One of financial advisor Jeff Barnett\u2019s clients called him when SpaceX went public on June 12<\/a>. Had Barnett bought any shares for the portfolio? He had not\u2014SpaceX came nowhere close to the client\u2019s preset criteria on valuation and governance.<\/p>\n

The client listened, then asked Barnett, \u201cCan we just buy 10 shares?\u201d Barnett got it done. He likens it to buying a lottery ticket when the jackpot hits $1 billion. You know the odds are slim, but a small bet buys a share of the buzz\u2014and scratches that deep down what-if itch\u2014without jeopardizing your portfolio.<\/p>\n

The fear of missing an on-ramp to the next generation of world-changing companies is the most expensive force in the market this summer. Investors call this trio the new Magnificent Three. SpaceX, Anthropic, and eventually OpenAI are the IPOs people are dreaming about, especially if they feel the ache of missing out on Nvidia: $10,000 in Nvidia<\/a> a decade ago would be worth roughly $1.8 million today. When SpaceX went public, more than 500 million shares traded\u2014marking the second-heaviest first-day IPO volume<\/a> in Nasdaq history, behind only Facebook\u2019s 580 million in 2012.<\/p>\n

But here\u2019s the thing. If you missed day one, all is not lost. And in fact, history shows you may have better opportunities to buy in the future.<\/p>\n

The typical (median) IPO is down about 26% three years after its first-day closing price, and some of the initial winners aren\u2019t the ones that become household names. Familiar with the biotechs Abgenix or Enzo Biochem? They had stellar debuts, up 2,071% and 2,445% from their first-day close, data from IPO expert Jay Ritter shows. However, they eventually cooled while it was the patient investors that backed Moderna<\/a> who saw the fifth-highest return among the 1,020 life-science IPOs from 1980 to 2024.<\/p>\n

\"\"<\/p>\n

Here are three top rules investing pros use to evaluate the biggest IPOs.<\/p>\n

Rule No. 1: Don\u2019t buy the first day.<\/p>\n

Barnett has some cold water to pour on the hot IPO summer. If the shares are easy to get, it\u2019s probably because more privileged buyers already passed. SpaceX spent more than two decades as a private company, and its early investors hold 12.5 billion shares at an average cost of $6.48. Elon Musk\u2019s space company then priced its shares at $135; the stock opened at $150; and it ended its first day on a 19% surge at $160.95.<\/p>\n

Even if you got in at $135, that\u2019s a hefty markup for a company trading at about 95 times its trailing annual sales, based on SpaceX\u2019s $18.7 billion in 2025 revenue and $1.77 trillion IPO valuation.<\/p>\n

That doesn\u2019t mean public markets are a dead end\u2014far from it, argues Matt Witheiler of Wellington Management, who invests in companies before they go public. Yes, more and more value is being created while a company is private. For instance, SpaceX grew from a startup into a $2 trillion company before it raised gross proceeds of $85.7 billion in its IPO.<\/p>\n

\u201cBut that does not mean there is not value creation in the public market as well,\u201d notes Witheiler. Look at the scoreboard, he says. The world had never seen a trillion-dollar public company until Apple<\/a> crossed the line in 2018. Eight years later there are 16, with Nvidia pushing toward $5 trillion.<\/p>\n

Just like at a job, the first day is just that and usually isn\u2019t the standout. A newly public stock stays \u201cunseasoned\u201d for about three years, explains Avery Marquez, director of investment strategies at Renaissance Capital, and those years are usually its most volatile and transformative period. Better entry points often open up months after the IPO, when all the hype has died down. SpaceX spiked to $225 within days of the IPO, then fell back to $160. Missing the IPO does not mean you\u2019ve missed out on anything.<\/p>\n

Rule No. 2: Follow the revenue.<\/p>\n

Witheiler has a blunt instrument for telling a lasting company from a good story.<\/p>\n

\u201cYou show me the numbers, and it\u2019s obviously real or not,\u201d the Wellington private-company money manager says.<\/p>\n

By early 2026, OpenAI\u2019s annualized run rate figures had crossed $25 billion. By May, Anthropic\u2019s had reached roughly $47 billion and publicly guided to more than $50 billion. That\u2019s a far cry from the dotcom bust, when investors bought companies that looked cheap on an \u201ceyeball basis\u201d but had no sales underneath.<\/p>\n

\u201cWe have companies whose customers are opening their wallets and spending gigantic amounts of money,\u201d Witheiler says. It\u2019s a meaningful tell.<\/p>\n

Still, the addressable market has to be \u201cabsolutely unbounded,\u201d he notes\u2014like the orbital data centers from SpaceX that could perhaps be among the largest data centers ever. The takeaway is to ask what the company sells, who\u2019s paying for it, and whether it all seems big enough to be worth the hype.<\/p>\n

Rule No. 3: Read the prospectus.<\/p>\n

Every fund manager who bought SpaceX read its S-1\u2014the disclosure document every company files with the Securities and Exchange Commission before going public. It\u2019s free and easy to read, and you can read it, too, says Marquez of Renaissance Capital.<\/p>\n

When it comes to retail investors, \u201ca lot of people don\u2019t,\u201d she notes. \u201cThey read the headlines, and that\u2019s pretty much it.\u201d<\/p>\n

Case in point: The headlines will tell you Musk aims to build a human colony on Mars with 1 million inhabitants, and that if he ever does, it\u2019ll help him make $1 trillion. The prospectus will tell you that SpaceX doesn\u2019t think he\u2019ll ever do it and hasn\u2019t set aside a penny of that $1 trillion, but it\u2019s giving him the shares underlying the pay package before he sends a speck of dust to Mars anyway. You\u2019ll also see that control of SpaceX resides firmly with Musk via billions of Class B super-voting shares that convert to Class A if he ever sells.<\/p>\n

The prospectus is also where a company priced on a five- or 10-year growth story details how it plans to achieve this, because what matters most is whether it can execute. All that happens post-IPO.<\/p>\n

One final tip: Look for the picks and shovels, says Bryan Wong, a portfolio manager at Osterweis Capital Management who manages its small-cap growth strategy. All the infrastructure and tooling companies (some already public) offer a much bigger field to pick a winner from\u2014giving you a much better shot at owning the next Nvidia, rather than the next Enzo Biochem.<\/p>\n
