Headlines love to announce that a stock "soared 200% on its IPO debut." What they rarely explain is that almost nobody buying on the news actually got that 200% gain. Understanding how IPO pricing really works reveals why that gap exists — and why it matters before you decide to buy.
Two Different Prices, One Confusing Headline
Every IPO actually involves two distinct prices, and confusing them is one of the most common mistakes new investors make.
- The offering price is the price set the night before trading begins, and it's the price paid by institutional investors who receive shares directly through the offering.
- The opening price is the price at which the stock first trades publicly the next morning, determined by actual buy and sell orders once the exchange opens the stock to everyone.
The gap between these two prices is where the "IPO pop" headlines come from — and it's a gap that retail investors buying on the open almost never get to capture.
How the Offering Price Gets Set
Setting the offering price isn't a guess — it's the result of a structured process that plays out over weeks.
The Roadshow
Before an IPO prices, company executives go on a roadshow, pitching the business directly to large institutional investors like mutual funds, hedge funds, and pension managers. Retail investors typically don't get a seat at this table.
Bookbuilding
During the roadshow, underwriters collect indications of interest from these institutional investors — essentially gauging how many shares each one wants and at what price. This process, called bookbuilding, helps underwriters understand real demand before settling on a final price.
Pricing Night
The night before trading begins, the company and its underwriters use everything gathered during bookbuilding to set the official offering price. This price reflects investor demand, the number of shares being sold, and overall market conditions at that moment.
Shares at this offering price are typically allocated almost entirely to institutional investors and select high-net-worth clients of the underwriting banks — not to everyday retail investors.
How the Opening Price Gets Set
The next morning, the stock doesn't simply start trading at the offering price. The exchange needs time to match buy and sell orders from the broader public before establishing an opening trade price — which is why IPOs often don't begin trading right at market open, but sometime later in the morning.
If public demand is strong, the stock can open well above the offering price — a classic IPO pop. If demand is weaker than expected, it can open flat or even below the offering price.
This opening price is the first price retail investors can generally access — and it's often already significantly higher than what institutional investors paid the night before.
A Real Example: Rivian
Rivian's 2021 IPO is a clear illustration of this gap in action. The company priced its offering at $78 per share — the price institutional investors paid. When public trading opened the next day, shares started around $106, already 36% above the offering price, and surged as high as $116 before closing day one at $100.73, up nearly 30% from the offering price.
Anyone reading a headline about Rivian's stock "soaring nearly 30%" wasn't seeing a gain measured from a price they could have actually paid at the open — they were seeing a gain measured from the $78 offering price, which only institutional investors got. Retail investors buying at the open were already starting from $106 or higher.
Why This Matters: The "Mispricing" Signal
It might seem like a huge first-day pop is great news — proof the company is a hot investment. In reality, a large gap between the offering price and the opening price often signals the opposite: that underwriters priced the deal too conservatively and left money on the table.
In other words, the company and its underwriters could have raised more money by setting a higher offering price, but they didn't. That's not necessarily a reflection of the company's long-term quality — it's more a reflection of how demand was estimated during bookbuilding. There's no strong evidence that a bigger first-day pop leads to better long-term stock performance.
What This Means for You as an Investor
Understanding this gap changes how you should think about IPO headlines:
- A big reported "gain" doesn't reflect what you could have earned unless you had access to shares at the offering price, which most retail investors don't.
- Buying at the opening price means buying near the peak of initial excitement, not at the beginning of a bargain.
- A large pop is not a reliable signal of quality — it often just reflects how conservatively the deal was priced.
None of this means IPOs are never worth buying. It simply means the price you see in the news is not the price you're actually being offered, and the size of a first-day pop tells you very little about the company's actual long-term prospects.
The Bottom Line
If you remember nothing else from this article, remember this: the price in the headline and the price you can actually pay are rarely the same number.
- Seeing a huge reported "IPO gain"? That's measured from a price only institutional investors got, not what you'd pay at the open.
- Tempted by a big first-day pop? It often just means the deal was priced conservatively, not that the company is a guaranteed winner.
- Not sure what to focus on instead? Skip the headline entirely and go straight to the company's actual fundamentals in the S-1.
The next time you see a headline about a stock "soaring" on its IPO debut, remember to ask: soaring from what price, and who actually got to buy at that price? Usually, it wasn't you.
