At a Glance
- SpaceX's IPO was this summer's most talked-about offering. OpenAI and Anthropic have both confidentially filed for public offerings. Additional marquee IPOs may be coming.
- An exciting company and an attractively priced stock are two different questions, and only one is something you control.
- Four questions worth asking before you buy an IPO — this one or the next one.
Few investments attract more attention than the initial public offering of a well-known private company.
SpaceX provided the latest example. The company priced its June IPO at $135 per share, and demand was intense. The stock rose sharply after trading began and then experienced a meaningful pullback, falling below the offering price by late July.
That early volatility is not a verdict on SpaceX's long-term prospects. It is a reminder that the price an investor pays matters. Investors who received shares at the offering price began in a materially different position from those who bought after public trading opened and the initial excitement had already lifted the stock.
OpenAI and Anthropic may create the next wave of IPO attention. Anthropic announced that it confidentially submitted a draft registration statement to the SEC in June, and OpenAI has reportedly done the same. Neither company has established an offering price or timetable. That uncertainty has not stopped investors from imagining what an allocation might be worth.
An Exciting Company and an Attractive Stock Are Different Questions
A company may have an extraordinary product, a large market and an impressive management team. Its stock can still disappoint if investors pay a price that already assumes years of exceptional growth.
This is particularly relevant for companies associated with transformative technologies. Investors are not merely evaluating the business as it exists today. They are paying for expectations about market share, future profitability and opportunities that may take years to develop.
The question is not simply whether SpaceX, OpenAI or Anthropic could become much larger businesses. It is how much of that possible success is already reflected in the price.
The First-Day Gain May Not Be Your Gain
IPO headlines often focus on the difference between the offering price and the first day's closing price. That can create the impression that the gain was broadly available.
It usually was not.
The offering-price return belongs to the investors who actually received an allocation. The most sought-after IPOs may be heavily oversubscribed, leaving investors with only a small allocation or none at all. Everyone else must decide whether to buy after trading begins, when the initial increase may already be reflected in the market price.
That distinction does not make an IPO allocation automatically attractive or a post-IPO purchase automatically unattractive. It means they are different decisions and should be evaluated separately.
The Historical Record Calls for Restraint
Some newly public companies become exceptional long-term investments. The challenge is identifying them in advance and paying a price that leaves room for the business to exceed expectations.
Research compiled by University of Florida professor Jay Ritter documents both the substantial average first-day gains associated with U.S. IPOs and their less impressive longer-term record. Studies have repeatedly found that IPOs as a group have tended to lag comparable public companies after their first day of trading.
The evidence does not tell us that every IPO will disappoint. It tells us that excitement, familiarity and a large first-day increase have not historically improved the odds for investors buying afterward.
Investing and Speculating Serve Different Purposes
Long-term investing begins with a financial objective. The portfolio is built around the investor's time horizon, cash-flow needs and ability to withstand market declines. Success should not depend on one company, one technology or one forecast being correct.
Speculation begins with a particular outcome: a company dominates a new industry, a technology develops as expected or other investors agree to pay a much higher price in the future.
There is nothing inherently wrong with making a speculative investment. Some investors can comfortably reserve a small portion of their assets for opportunities they find compelling. The important part is labeling the position correctly and sizing it so that a disappointing result would not alter the financial plan.
Four Questions to Ask Before Buying an IPO
- Am I receiving the offering price or buying after trading begins? The potential return and downside can be very different once the first-day demand is reflected in the price.
- What future does the valuation already assume? A compelling story is not enough. The company must eventually produce results that justify the price being paid.
- Is this part of my investment strategy or a speculative position? A speculative holding should be deliberately sized rather than quietly allowed to become a core position.
- What would happen if the stock declined by 50%? If that decline would affect spending plans, retirement security or the ability to stay disciplined, the position is probably too large.
You Do Not Have to Be First
Fear of missing out creates urgency. Investors can feel as though the opportunity will disappear if they do not buy immediately.
For a company capable of compounding its value over decades, the first day should not be the only opportunity. Waiting allows investors to review public financial statements, observe management's execution and see how the stock trades once the initial scarcity and excitement begin to normalize—and if you decide it is worth owning.
SpaceX's post-IPO volatility provided a useful reminder. OpenAI and Anthropic may provide the next one. The objective is not to avoid every new offering. It is to make sure that excitement does not replace valuation, diversification and position-size discipline.
There will always be another highly anticipated IPO. Your financial plan should not depend on correctly predicting which one reaches orbit.
