Pricing an IPO is probably more art than science
In the long arc of capitalism's evolution, the act of a private company opening itself to public ownership remains one of the most consequential rituals of modern economic life. SpaceX, the company that has already reshaped humanity's relationship with space, is preparing to undergo that ritual in 2026, joined by AI giants OpenAI and Anthropic in what could become a landmark year for markets. The process — from SEC filings to investor roadshows to the delicate alchemy of share pricing — is a reminder that even the most visionary enterprises must eventually submit to the scrutiny and judgment of the crowd.
- Three of the most consequential private companies in the world — SpaceX, OpenAI, and Anthropic — are moving simultaneously toward public markets, creating a convergence that could shatter IPO records set just a year ago.
- SpaceX's expected S-1 filing this week triggers a months-long regulatory gauntlet, forcing the secretive rocket company to open its finances and business model to full public scrutiny for the first time.
- A planned June event targeting 1,500 individual investors signals that SpaceX is not just courting Wall Street institutions but attempting to build broad retail enthusiasm — a strategy that carries its own risks if market sentiment shifts.
- The ghost of failed IPOs looms large: fintech firm Clear Street abandoned its listing in February after failing to generate investor interest, a cautionary tale about the volatility that can derail even well-prepared debuts.
- The pricing decision — too high and the stock craters on day one, too low and billions are left unclaimed — remains the razor's edge on which the entire enterprise balances, with only a few dollars per share separating triumph from disaster.
Last year, American companies raised $70 billion going public. This year could surpass that entirely. SpaceX is preparing its first public share offering, and so are OpenAI and Anthropic. If all three proceed, 2026 may rewrite the record books for initial public offerings.
The machinery of an IPO is simple in concept and brutal in execution. It takes months, costs millions, and demands that a company open its books entirely — to regulators, investors, and the public. The reward, if done right, is access to vast capital and a publicly traded stock that can fuel acquisitions, employee compensation, and growth.
The first decision is where to list. In the United States, two exchanges dominate: the New York Stock Exchange, with its storied trading floor in lower Manhattan, and the Nasdaq, the fully electronic home of most of the world's largest technology companies. A company must also choose a ticker symbol — the short code that will define it on every financial screen going forward.
Before any shares can be sold, the company files an S-1 with the Securities and Exchange Commission — an exhaustive document detailing finances, business model, risks, and leadership. The SEC reviews it, asks questions, demands clarifications. This back-and-forth can stretch for months. SpaceX is expected to file its S-1 this week.
Once paperwork is in motion, executives hit the road. City to city, and increasingly screen to screen, they pitch to pension funds, hedge funds, and individual investors. SpaceX is planning a special June event for 1,500 retail investors. Not every company makes it this far intact — fintech firm Clear Street abandoned its IPO in February after failing to generate sufficient interest amid market volatility.
The hardest moment may be pricing. Underwriting banks want to raise as much as possible, but price too high and there is no demand on opening day — the stock falls while executives watch in real time. Price too low and billions go uncaptured. Cerebras, a chip startup, revised its target price twice before settling at $185 a share; the stock soared 68 percent on its first day of trading. That is the dream. But between triumph and disaster, the margin is often just a few dollars per share.
Last year, American companies raised $70 billion by going public. This year could be different. SpaceX, the rocket manufacturer and space logistics company, is preparing to sell shares to the public for the first time. So are OpenAI, the artificial intelligence company behind ChatGPT, and Anthropic, another AI startup. If all three proceed, 2026 could rewrite the record books for initial public offerings—the formal process by which a private company becomes a publicly traded one.
The machinery of an IPO is both simple in concept and brutally complex in execution. It takes months, sometimes years. It costs millions of dollars. And it requires a company to open its books entirely to scrutiny—to regulators, to investors, to the public. The payoff, if done right, is access to vast pools of capital and a currency (publicly traded stock) that can be used for acquisitions, employee compensation, and growth.
The first decision is where to list. In the United States, two exchanges dominate: the New York Stock Exchange, the oldest and most storied, with its physical trading floor in lower Manhattan, and the Nasdaq, a fully electronic system that has become home to most of the world's largest technology companies. Together, these two exchanges represent roughly half the total value of all stocks traded globally. A company must also choose a ticker symbol—the short letter code that will identify it on screens and in financial news. Microsoft uses MSFT. Krispy Kreme chose DNUT. Avis went with CAR. SpaceX will need to pick one too.
Before any shares can be sold, the company must file a document called an S-1 with the Securities and Exchange Commission, the federal agency that polices financial markets. This filing is exhaustive. It details the company's finances, its business model, the risks it faces, the people who run it. The purpose is dual: to register the securities with the government and to give ordinary investors enough information to make an informed decision about whether to buy. The SEC reviews the filing, asks questions, demands clarifications. This back-and-forth can take months. SpaceX is expected to file its S-1 this week, according to sources familiar with the company's plans.
Once the paperwork is in motion, the real selling begins. Company executives travel city to city—and increasingly, hop on video calls—in what is called a roadshow. They pitch their company to institutional investors like pension funds and hedge funds, but also to individual retail investors who might buy a few shares. SpaceX is planning a special event in June for 1,500 individual investors, according to reporting from CNBC. Not every company survives this stage. Clear Street, a fintech firm, abandoned its IPO plans in February after failing to generate sufficient investor interest, citing market volatility as the reason.
The hardest part may be deciding what price to charge for a single share. This is where art meets science, or perhaps where science loses entirely. The underwriting banks advising the company want to raise as much money as possible—a higher share price means more capital flowing into the company's coffers. But they also need to leave room for the stock to rise once trading begins. If the initial price is too high, there will be no demand on day one. The stock will fall. The executives ringing the opening bell will watch their company's value crater in real time. "If you really seek to maximize the share price, you're going to have very little aftermarket demand and the IPO can flop," said Matthew Kenney, an IPO specialist at Renaissance Capital. Sometimes companies misjudge. Cerebras, a chip startup, revised its target price twice before finally pricing its IPO at $185 a share. On the first day of trading, the stock soared 68 percent. That is the dream. But it is not guaranteed, and the margin between triumph and disaster is often just a few dollars per share.

Why does SpaceX need to go public now? Hasn't Elon Musk been able to fund the company privately?
SpaceX has grown enormous—it's launching rockets, building satellites, planning Mars missions. At a certain scale, the capital needs outpace what private investors and founders can reasonably provide. Going public unlocks a much larger pool of money, and it gives employees a way to cash out their equity stakes.
What's the SEC actually checking for in that S-1 filing?
They're making sure the company isn't lying or hiding material risks. They want investors to understand what they're buying into—the financials, the competition, whether the business model actually works. It's a protection mechanism, though imperfect.
Why would a company price its IPO too low if it means leaving money on the table?
Because pricing it too high is worse. If nobody wants to buy at that price, the stock tanks on day one, and you've humiliated yourself in front of the entire market. Better to be conservative and watch it pop than to be greedy and watch it crash.
Is there any chance SpaceX's IPO doesn't happen?
It's possible. Market conditions matter. If volatility spikes or investor appetite for tech stocks cools, SpaceX could delay. Clear Street did exactly that. But SpaceX has more momentum and clearer revenue than most startups, so the odds seem good.
What happens to Elon Musk's stake when SpaceX goes public?
He'll own a percentage of a publicly traded company instead of a privately held one. His shares will have a market price, which means they're more liquid—he could sell them—but also more volatile. His net worth will fluctuate with the stock price every single day.
