How IPOs Work
A company that wants to go public files a registration statement (Form S-1 or F-1) with the SEC, works with banks to gauge demand, and sets a price range. The night before trading, the final offer price is set and the IPO is marked ● Priced. Until then it shows as ● Expected.
On the first day, shares open at a price set by buyers and sellers, which can be well above or below the offer price. Deal size is the offer price times the shares sold.

What is an IPO?
An initial public offering (IPO) is when a private company sells shares to the public for the first time and its stock starts trading on an exchange like the Nasdaq or NYSE.
When can I buy an IPO stock?
Most everyday investors can buy shares once the stock opens for trading on its first day. Some brokers also offer access to shares at the IPO price before trading begins.
What does Expected vs. Priced mean?
Expected means the IPO is scheduled but the final price is not set yet. Priced means the company and its banks have set the offer price, usually the night before trading starts.

Companies can move an IPO earlier or later, or cancel it, based on market conditions and SEC review. This month Rezera postponed its IPO and OPay called off its NYSE debut after pricing.
