Every few years, a company goes public that feels like a once-in-a-generation opportunity. In June 2026, it was SpaceX. In 2021, it was Rivian. In 1999, it was Pets.com and a hundred others. Each time, the media runs the same stories. Retail investors open brokerage accounts. Stock prices surge on Day 1. And most people who bought at the hype peak spend the next three years watching the stock trail the broader market.
The short answer: Buying a hyped IPO at listing is almost always the wrong move for retail investors. A study of 1,479 US IPOs from 2012–2021 found average 36-month returns of −16% vs the market. In India, 59% of 2025 IPOs were trading below their listing price by year-end. The Day 1 pop is real. The long-term return is not. The research below explains why, gives you a numerical framework to evaluate any IPO, and tells you when it actually does make sense to buy.
What You Are Actually Buying at an IPO
Most retail investors believe they are getting early access to a great company at the ground floor. They are not.
When a company goes public, the price is set by investment banks (underwriters) through a process called bookbuilding. Institutional investors - sovereign wealth funds, pension funds, hedge funds, mutual funds - submit bids. The underwriters set a price that maximizes what the company raises, which is not the same as a price that is fair to buyers.
Then retail investors are offered shares. But the retail “IPO price” is the bank-set price that already reflects institutional demand. And on listing day, the price typically opens above even that. The “pop” everyone talks about - the 19% first-day gain on the SpaceX IPO, or the 109% surge when LinkedIn listed - is not a gift to investors. It is the cost of small supply meeting enormous demand.
Here is the math of how artificial demand gets created:
SpaceX sold approximately 4.2% of its total shares outstanding in the IPO. That means 95.8% of the company was not available for purchase. Now imagine every major investment bank, 50 sovereign wealth funds, 200 mutual funds, and 30 hedge funds all wanting exposure to the world’s most talked-about company. They are competing for 4.2% of it. Of course the price gets bid up. Of course there is a Day 1 pop. But that pop measures supply constraint, not value.
The retail investor buying at the market open on Day 1 is buying at the peak of that artificial supply constraint - paying the price set by institutional competition, not by independent valuation.
There is a second thing most investors do not know: you are almost never getting the actual IPO price. The IPO price ($135 for SpaceX) goes to institutional investors and the preferred clients of underwriting banks. Retail investors who buy on the exchange on listing day pay the market-open price - $160.95 for SpaceX, already 19.2% above the IPO price. The “opportunity” retail investors access is already marked up before trading begins.
The SpaceX Case Study - Facts, Not Narrative
SpaceX debuted on the Nasdaq on June 12, 2026, raising $75 billion at a valuation of $1.77 trillion. It was the largest IPO in financial history, surpassing Saudi Aramco’s $29.4 billion raise in 2019.
The business is genuinely extraordinary. Consider the 2025 financials from SpaceX’s S-1 filing:
- Total revenue: $18.7 billion (up 43% year-on-year from $13.1 billion in 2024)
- Starlink revenue: $11.4 billion (61% of total, up 48% from $7.7B in 2024)
- Starlink operating profit: $4.4 billion
- Starlink subscribers: grew from 4.6 million (end-2024) to 10.3 million across 160 countries
- Adjusted EBITDA: $6.6 billion
Those numbers are impressive. SpaceX is a real business generating real cash. Starlink, the satellite internet division, is on a trajectory that would make it one of the most valuable standalone businesses in the world if it were listed separately.
And yet.
Morningstar’s independent DCF analysis valued SpaceX at $780 billion - less than half the $1.77 trillion IPO valuation. Analyst Nicholas Owens assigned the company’s core launch and Starlink businesses a combined enterprise value of $611 billion, plus $170 billion of probability-weighted scenarios for AI operations, for a total fair value of $780 billion. That is a 56% discount to the listing price.
Morningstar was not saying SpaceX is a bad company. They were saying: at $1.77 trillion, you are paying for a scenario that has only a small probability of occurring. The price assumes Starlink will penetrate markets - in the developing world, in aviation, in maritime - at a scale that the data does not yet support. You are paying today for a future that may or may not arrive.
Meanwhile, on Reddit: “Lol no one is buying SPCX on fundamentals.” That quote, reported by Benzinga from r/investing discussions, is the most honest description of the IPO market in 2026. Retail investors openly acknowledged they were speculating, not investing. The stock added roughly $800 billion in market cap within two trading days of listing - powered largely by retail trading flows.
By late June 2026, SPCX had retraced from its intraday high of $225.64 to around $153 - still above the $135 IPO price, but 32% below the peak that retail FOMO created.
The company is real. The valuation at IPO was not.
The Math That Decides Long-Term Returns
To understand why most hyped IPOs underperform, you need one ratio: Price-to-Sales (P/S).
P/S = Market Cap ÷ Annual Revenue
It tells you how much investors are paying per rupee (or dollar) of revenue. It is the most useful metric for companies that are pre-profitability or whose profits are distorted by heavy investment - which describes most large IPOs.
SpaceX at IPO:
- Market cap: $1.77 trillion
- Revenue (2025): $18.7 billion
- P/S ratio: ~95x
That means investors paid $95 for every $1 of SpaceX revenue.
Is that rational? Here is the historical data from Jay Ritter’s IPO research database (University of Florida) and WisdomTree analysis:
- For companies with P/S above 25, only 4% outperformed the market over 20 years
- Median relative return in year 1 for P/S >25 companies: −36% vs the benchmark
- 3-year annualized return for high P/S stocks: −4.4% annualized vs +9% for the market
At 95x revenue, SpaceX is priced many standard deviations above even the “risky” category.
A practical calculation framework:
A useful shorthand is to compare P/S to the revenue growth rate:
P/S ÷ Revenue Growth Rate
If this number is under 1, you have some margin of safety. If it is over 2, you are paying a premium that requires perfect execution of an optimistic plan.
- SpaceX: 95 ÷ 43 = 2.2 (expensive)
- A company with P/S 8 and revenue growth 30%: 8 ÷ 30 = 0.27 (reasonable)
- Rivian at peak IPO: ~3,000 ÷ estimated growth = effectively infinite
This does not tell you whether a company will succeed. It tells you how much perfection is already priced in.
There is a second number to check: GAAP vs. adjusted profitability. SpaceX reported $6.6 billion in “adjusted EBITDA” but a GAAP net loss of $4.9 billion. Both numbers are true and both are disclosed in the S-1. The adjusted number strips out stock-based compensation, debt interest, and xAI integration costs. The GAAP number is what accounting standards say the company actually earned. Most IPO marketing materials show the adjusted number. The income tax department cares about the GAAP number. So should you.
Five Historical Precedents That Repeat Every Cycle
1. The Dot-Com Bubble (1999–2002)
In October 1999, 199 internet companies had a combined market cap of $450 billion on annual revenue of $21 billion - a blended P/S of 21x, with collective losses of $6.2 billion. Companies like Pets.com, Webvan, and eToys went public with zero path to profitability and multi-billion dollar valuations because the narrative of “internet changes everything” overwhelmed any valuation discipline.
VA Linux set an IPO record with a 700% first-day surge in December 1999. It never came close to that price again.
The NASDAQ fell 75% between March 2000 and October 2002, erasing over $5 trillion in market value. The signal that it was over: in the month before the NASDAQ peaked, insiders at publicly listed tech companies were selling shares at a rate 23 times higher than they were buying. Retail investors, reading the same bullish headlines, poured $260 billion into equity funds in that final month.
The internet did change everything. Amazon, Google, and Apple became the most valuable companies in history. But investors who bought the narrative at peak hype in 1999 had to wait until 2013 - fourteen years - for the NASDAQ to recover its highs.
The lesson: A correct thesis about an industry does not tell you when or at what price the market will price that thesis fairly.
2. Rivian (2021 - United States)
Rivian Automotive IPO’d in November 2021 at $78 per share. Within days, the market cap hit $153 billion - approximately 3,000 times its 2021 revenue of $55 million. The company had genuine products: it had won a contract to build 100,000 electric delivery vans for Amazon. Ford had invested in it. The technology was real.
By June 2026, RIVN traded at $15.63 - a decline of 89% from the IPO price.
Revenue grew from $55 million in 2021 to over $5 billion over the next four years. The company built real vehicles. The stock still lost 89% of its value for IPO buyers. The valuation math simply never worked.
If you had invested ₹10,000 in Rivian at IPO and held through 2026, you would have ₹1,100 left.
3. LinkedIn (2011 - United States)
LinkedIn is the most cited counter-argument: a Day 1 pop that preceded long-term success. LinkedIn IPO’d at $45 in May 2011, surged 109% on listing day to $94, and was eventually acquired by Microsoft in 2016 for $196.
But here is what the counter-argument misses: investors who bought at the Day 1 high of $94 had to wait 18 months just to break even. The stock pulled back 33% through the end of 2011 before recovering. Even in the success case, buying at the Day 1 price cost you a year and a half of returns compared to buying in the secondary market three months later.
4. India 2025 IPO Market
India’s 2025 IPO market was the largest primary market in the world by capital raised: 108 mainboard IPOs raising ₹1,83,432 crore. The headline numbers looked good - 65% of IPOs listed at a gain.
But here is the data that does not get covered: 59% of those 2025 IPOs were trading below their listing price by year-end. Median listing gains fell sharply to 3.8% in 2025 from 15.2% in 2024 - meaning even the average gain on listing day was barely a SIP return. And for investors who chased the grey market premium and bought above the listing price, results were materially worse.
The world’s largest IPO market, by capital raised, delivered negative real returns for the majority of retail buyers who got in on listing day.
5. Facebook (2012 - United States)
Facebook IPO’d in May 2012 at $38/share, valuing it at $104 billion. It was the most hyped IPO since the dot-com era. The stock fell to $17.55 within three months of listing - a 54% decline from the IPO price. For a full year, the stock traded below its IPO price.
Facebook’s business was real and ultimately became one of the most profitable in history. But investors who bought at the IPO and sold in frustration at $17 in September 2012 locked in a 54% loss. Patience and a lower entry point - both available to anyone who simply waited - would have given dramatically better returns.
The Three Hidden Clocks Every IPO Investor Must Track
Most retail investors track one number: the IPO price. The sophisticated framework tracks three time-based events that structurally affect supply and price.
Clock 1 - The Lock-Up Expiry
In India, under SEBI’s ICDR regulations:
- Retail investors who receive shares through the public issue have no lock-in. They can sell immediately.
- Promoters holding the minimum 20% contribution are locked in for 18 months from allotment.
- Excess promoter holdings above 20% are locked in for 6 months.
- Pre-IPO investors (VC funds, PE firms) face a 6-month lock-in.
- Anchor investors have 90-day lock-in on 50% of their allocation.
In the US, the standard is 180 days (approximately 6 months).
Here is why this matters practically: the people who are locked up - promoters, pre-IPO investors, anchor investors - have cost bases that are a fraction of the IPO price. When the lock-up expires, they have a strong incentive to sell, even if the business is doing well. That creates a predictable supply shock approximately 6 months after listing. Stocks frequently see a second significant drawdown around this date, regardless of business performance.
Mark the lock-up expiry date in your calendar on Day 1 of any IPO you are watching. It is the most important date for entry planning.
Clock 2 - The Quiet Period End (25–40 days post-IPO)
For 25–40 days after an IPO, investment banks that underwrote the deal are barred from publishing research on the company. When the quiet period ends, those banks release analyst reports - and they have a financial incentive to publish bullish coverage (they were paid by the company to list it). This can create a short-term price bump.
Independent research - from firms like Morningstar that had no role in the IPO - is the only unbiased analysis. And as the SpaceX case showed, independent analysis often arrives at valuations dramatically below the IPO price.
Clock 3 - The First Earnings Report Post-IPO
The IPO prospectus (S-1 or DRHP in India) is a marketing document as much as a legal disclosure. It shows historical financials but also management projections and forward-looking statements. The first quarterly earnings report as a public company is when the market gets its first unfiltered look at whether the business is actually performing to the narrative. This typically comes 90–120 days after listing.
If the first earnings miss is even slightly below expectations, an overvalued IPO stock can fall sharply. This is when disciplined investors find their entry points.
What Indian Investors Specifically Need to Know
The SpaceX IPO is a US-listed stock, not directly accessible to most Indian retail investors without an international brokerage (like Vested, INDmoney’s US stocks platform, or a foreign brokerage account) and LRS (Liberalised Remittance Scheme) funds. So why does it matter for Indian investors?
Because the behavioral patterns that inflate SpaceX are identical to what inflates every hot Indian IPO. The mechanism - small float, institutional FOMO, narrative compression, retail herd behavior - is the same whether you are talking about SPCX or an Indian startup IPO listing on BSE.
Five India-specific facts to know:
1. The grey market premium (GMP) is not a valuation signal. GMP is an off-market, unregulated indicator that SEBI does not recognize. It reflects speculative demand in a thin, informal order book. Business Standard and SEBI have both explicitly warned investors not to use GMP to decide IPO applications. It measures excitement, not value.
2. Retail allotment does not mean retail investors won. SEBI mandates that at least 35% of an IPO be reserved for Retail Individual Investors (RIIs, those investing up to ₹2 lakh). Getting shares allotted does not mean the price was right - it means you participated. The question is whether you paid the right price for what you received.
3. Oversubscription numbers are a hype signal, not a quality signal. An IPO that is oversubscribed 100 times means 100 people wanted every share available. It tells you about demand. It tells you nothing about whether the price is fair or whether the business will perform. The most oversubscribed IPOs in history have included catastrophic losses for investors.
4. India’s 2025 data confirms the global pattern. Of 108 mainboard IPOs in 2025, 65% listed at a gain. But 59% were trading below their listing price by year-end. Median listing gains of 3.8% compare unfavorably to even a fixed deposit. The lottery of which 41% were above listing price is not a strategy.
5. The LRS route for US IPOs has its own risks. If you use LRS funds to invest in a US IPO through an international broker, you face currency risk (USD/INR), PFIC tax complications if the US company has foreign subsidiaries, TDS implications on US dividends under DTAA (Double Taxation Avoidance Agreement), and the same behavioral traps as described above - amplified by the glamour of investing in a “global” story.
The Decision Framework - With Actual Numbers
Here is a framework that applies to any IPO, in any market, at any time. Not based on a prediction about SpaceX specifically - based on what has historically determined returns.
Step 1 - Calculate the P/S ratio
P/S = Market Cap ÷ Annual Revenue. This tells you how much investors are paying per rupee of sales.
- P/S below 5 - Low concern. Focus on business quality.
- P/S 5 to 15 - Moderate. The growth rate must justify the premium.
- P/S 15 to 25 - High. Strong evidence of a durable moat is required.
- P/S above 25 - Statistically unfavorable. Only 4% of such companies beat the market over 20 years.
- P/S above 50 - Effectively speculative, not investment-grade.
Step 2 - Calculate the PEG-equivalent
Divide the P/S by the company’s revenue growth rate (as a percentage). This adjusts the valuation for how fast the business is growing.
- Below 0.5 - Reasonable margin of safety.
- 0.5 to 1 - Priced fairly for the growth rate.
- 1 to 2 - Premium pricing with minimal margin of safety.
- Above 2 - The story is fully priced in. You need to be right about everything.
Step 3 - Check the profitability basis
Is profitability reported only on an “Adjusted EBITDA” basis? If yes, the company is GAAP-loss-making - discount the valuation further. If the company is GAAP-profitable, evaluate normally.
Step 4 - Check the float size
Float = Shares sold in IPO ÷ Total shares outstanding.
- Below 5% - Artificial scarcity. Day 1 price is meaningless. Wait.
- 5% to 15% - Moderate. Some artificial demand still present.
- Above 20% - More representative price discovery.
Step 5 - Set your calendar
Mark two dates immediately: the lock-up expiry date and the first post-IPO earnings release. These are your structural re-evaluation points, not guesses - they are predictable events that structurally affect supply and price.
Step 6 - Decide
- P/S above 50, GAAP loss-making, and float below 10% - Wait. No position. Watch from the sideline and re-evaluate at lock-up expiry.
- P/S between 15 and 50, strong revenue growth (30%+), GAAP improving - Small position only (1 to 2% of portfolio), not before lock-up expiry, and not more than you can afford to lose completely.
- P/S below 10, revenue growing 25%+, path to GAAP profitability within 3 years - Serious research is warranted. Read the DRHP or S-1 and evaluate the business on its merits. Can size more normally (3 to 5% of portfolio) with genuine conviction.
The overriding rule: Size your position in inverse proportion to the valuation premium. The more the market is paying for the story, the less of your money should be in it.
10 Things Retail Investors Get Wrong About IPOs
1. I am buying at the IPO price
You are not. Institutional investors get the IPO price. You pay the market-open price on listing day - already above the IPO price. The Day 1 pop happened between the IPO price and your first available purchase price.
2. Great company = great stock
Rivian is a real company building electric vehicles for Amazon. Down 89%. Uber completely changed global transportation. Traded below its IPO price for years. Facebook became one of the most profitable businesses in history. Fell 54% in its first three months as a public company. The business quality is not the question. The price you pay is.
3. The Day 1 pop means the market is confirming the value
The Day 1 pop means supply was constrained. That is all. A pop of 19% (SpaceX) or 109% (LinkedIn) or 700% (VA Linux) tells you how many institutional buyers wanted a share of a tiny float. It tells you nothing about whether the business will grow into its valuation.
4. I will flip it on Day 1 and take the profit
This works sometimes. It fails when you buy at the intraday high on a volatile listing. SpaceX peaked at $225 intraday four days after listing and retraced to $153 within weeks. Identifying the intraday peak requires luck, not skill. Many retail investors chasing the pop buy near the top and sell near the first drawdown.
5. The grey market premium tells me what to do
GMP is to IPO investing what horoscope readings are to career planning. It is unregulated, informal, manipulable, and has no demonstrated predictive accuracy for listing performance - let alone three-year returns.
6. High oversubscription means this is a good deal
Oversubscription measures demand at a given price. It does not validate the price. In a hot IPO market, retail investors will oversubscribe almost anything with media coverage. The 1,500x oversubscribed IPOs that subsequently lost investors money are not rare exceptions; they are the statistical norm.
7. If insiders are keeping their shares, it must be a good sign
Insiders cannot sell for 6–18 months (depending on category, under SEBI rules). Their “decision” not to sell is not a decision - it is a regulatory constraint. Watch what happens at lock-up expiry. That is when informed selling becomes visible.
8. Adjusted EBITDA profitability means the company is profitable
No. Adjusted EBITDA strips out stock-based compensation (real economic cost to shareholders), depreciation on assets (real economic wear), debt interest (real cash outflow), and restructuring costs (often recurring). GAAP net income is the legally recognized measure of profitability. SpaceX: $6.6B adjusted EBITDA, $4.9B GAAP net loss. Both numbers are real. The adjusted one gets used in the pitch deck.
9. I need to act fast before the opportunity disappears
This is the manufactured urgency of IPO marketing. The stock trades every day after listing. It will be available at lower prices more often than higher prices over the first three years, based on historical data. The “opportunity” does not disappear - it often improves. Morningstar explicitly advised SpaceX investors to wait for a better entry point after the IPO hype fades.
10. Elon Musk / [Famous Founder] running it makes it a safe bet
Tesla IPO’d at $17 in June 2010. Within seven months, it had fallen to $9. An investor who bought at the IPO and sold in early 2011 lost nearly half their money. Tesla ultimately became one of the best-performing stocks in history - but that story took a decade to play out, and included a 50% drawdown within the first year.
Founder quality does not insulate you from paying too much.
When IPOs ARE Worth Buying
The data is not a blanket argument against all IPO investing. It is an argument against buying at the wrong price, at the wrong time, for the wrong reasons. Here are the conditions under which IPOs have historically rewarded investors.
1. When the float is large and price discovery is real
When a company sells 20–30% of its shares in the IPO, the listing price reflects more genuine supply-and-demand equilibrium. The Day 1 pop is smaller. The long-term performance is more correlated to actual business quality. Large float IPOs are boring headlines - they are better investments.
2. When you buy after the lock-up expiry, not at listing
Lock-up expiry creates predictable selling pressure. Stocks frequently see their best secondary-market entry points in the 6–9 month window after listing, when insider lock-ups have expired and initial hype has faded. The business is now a public company with a trading history. You can evaluate actual quarterly results rather than prospectus projections.
3. When the P/S ratio is under 10 with strong revenue growth
At a P/S below 10 with 25%+ revenue growth, you have a quantitative margin of safety. The market is not pricing perfection. Historical data gives you reasonable odds of market-beating returns over a 3–5 year horizon.
4. When the IPO is in a boring industry with no media narrative
The most reliable IPO returns historically come from industries that do not generate YouTube thumbnails. Logistics companies, specialty manufacturers, financial services firms - these rarely have 700% Day 1 pops, but they also do not require paying for narratives about colonizing Mars or ending transportation as we know it.
5. When your time horizon is 5+ years and you size conservatively
Even an overvalued great company can become a good investment if you hold long enough and did not oversize the position. Facebook buyers who held from $38 through the 2012 crash to $400 in 2021 made exceptional returns. The psychological cost of watching a 54% drawdown in year 1 is real - only concentrated conviction and a long time horizon make that tolerable.
The Questions to Ask Before Any IPO
If you are seriously considering investing in an IPO - Indian or international - work through this checklist:
About the business:
- What does this company actually sell and to whom?
- Is revenue growing, and at what rate?
- Is the company GAAP profitable, or only on an adjusted basis?
- What is the largest risk to revenue - competition, regulation, technology change?
About the valuation:
- What is the P/S ratio? (Market cap ÷ revenue)
- What is the P/S ÷ revenue growth ratio? Is it under 1?
- What would an independent DCF model produce at conservative assumptions?
- Is there a Morningstar, ICICI Securities, or similar third-party research note that is independent of the underwriters?
About the structure:
- What percentage of shares are being sold (float size)?
- Who is selling - the company (primary shares, money goes to business) or founders (secondary shares, money goes to founders)?
- When is the lock-up expiry for promoters and pre-IPO investors?
- When does the first earnings report post-IPO come out?
About yourself:
- Am I reading about this IPO everywhere right now? (If yes: that is the hype signal, not a quality signal)
- If the stock falls 40% in the first year, will I hold or will I panic-sell?
- Is this position sized so that losing it all does not change my financial plan?
- Would I be comfortable buying this same stock at this same price if it were a boring, un-hyped company?
If you cannot answer all of these questions, you are not ready to invest - you are ready to speculate. Both are choices. Only one should be deliberate.
The Honest Summary
SpaceX is a genuinely extraordinary company. Reusable rockets, 10 million Starlink subscribers, 43% revenue growth, the first company to commercially prove orbital-class reusability. The narrative is real.
The valuation at IPO was not.
At $1.77 trillion on $18.7 billion in revenue - a P/S of ~95x - the price assumed a version of SpaceX’s future that Morningstar assessed has less than a 10% probability of occurring within a reasonable timeframe. Retail investors who chased the peak at $225 in the days after listing were buying the story at its most expensive. Those who wait - for the lock-up expiry, for the first earnings cycle, for the inevitable convergence of price toward fundamental value - will likely find better entry points.
This is not a prediction about SpaceX specifically. It is a pattern that has repeated in every market, in every cycle, with every generation of once-in-a-generation companies.
The internet did change everything. Amazon and Google are the most valuable companies in history. But you had to survive from 1999 to 2013 - fourteen years - to recover the NASDAQ from its dot-com peak.
Great companies make bad investments at bad prices. Price paid is the variable you control. Everything else - the business, the macro, the competition, the technology - you do not.
Buy the math, not the story.
