IPO pricing is the step in which a company and its lead [underwriters](https://www.quantisnow.com/glossary/underwriter) set the final price per share and number of shares for an [initial public offering](https://www.quantisnow.com/glossary/ipo). The offer price is what investors who receive allocations pay; trading in the open market starts the next day.

## How it works

Once the SEC review is nearly done, the company amends its [Form S-1](https://www.quantisnow.com/glossary/form-s-1) to include an expected price range and share count, then launches a roadshow. Underwriters run a bookbuilding process, collecting indications of interest from institutional investors at different prices. At the end of the roadshow, usually after market close, the company and underwriters agree on a price and size based on demand. The final terms are announced by press release and in a final prospectus filed under [Rule 424(b)](https://www.quantisnow.com/glossary/form-424b).

Outcomes fall into a few buckets:

- **Above the range:** demand well in excess of supply
- **Within the range:** normal demand
- **Below the range or downsized:** weak demand
- **Upsized:** more shares sold, often a bullish sign
- **Postponed:** the deal is pulled, often in volatile markets

The range can also be revised during the roadshow through an amended filing.

## Why it matters for traders

Pricing is the clearest read on institutional demand before the first trade. Deals priced above an already raised range tend to open well above the offer price, while downsized deals often struggle. Underwriters intentionally leave some upside, the "IPO discount," to reward investors who commit. The opening print can differ greatly from the offer price, so a strong pricing does not guarantee a buyable entry.

## Example

Hypothetical Northwind Robotics (NWRB) sets an initial range of $15 to $17 for 12 million shares. Midway through the roadshow it raises the range to $18 to $20. It prices at $21, above the revised range, and upsizes to 14 million shares, raising $294 million.

## FAQ

### When is an IPO priced?

Usually the evening before the stock begins trading, after the roadshow ends and the order book is complete.

### Why is the opening price different from the IPO price?

The IPO price is set by underwriters from institutional orders. The opening price is set by the exchange's opening auction, reflecting all market demand.
