**Deep Fission’s IPO pricing and closing market cap reflect investor caution toward an early-stage, pre-revenue small modular reactor (SMR) developer despite nuclear tailwinds from AI data-center power demand.** The company filed its S-1 in mid-May 2026 targeting $24–$26 per share for roughly 6 million shares (plus greenshoe), implying a $1.66–1.7 billion fully diluted valuation at the midpoint to fund its first underground “Gravity” pressurized-water reactor pilot in Kansas under the DOE Reactor Pilot Program. By mid-June 2026, however, trader consensus has coalesced around a sub-$1.25 billion outcome (52% implied probability) because the firm remains years from revenue or regulatory approval, carries unproven deep-borehole deployment risks, and follows a prior non-trading reverse-merger attempt. The $3 billion-plus bucket (28.9%) captures residual hype around nuclear revival, while the $1.25–1.5 billion range (21.9%) represents a modest premium to the original range.

This market will resolve based on Deep Fission's market capitalization at the closing price on its first day of trading.
As of market creation, the IPO is scheduled to price on May 29 (ET). If no such IPO occurs by July 31, 2026, 11:59 PM ET, the market will resolve to "No IPO before August 2026".
Market capitalization expresses the monetary value of a company's outstanding shares, stated in its pricing currency.
It is calculated as the total number of outstanding shares, multiplied by the official closing share price of the publicly traded class on the first trading day.
If necessary, to accurately capture the company's total market capitalization, rather than a stock-class-specific market capitalization, the calculation will include all outstanding share classes and apply any stated conversion ratios to the publicly traded class. Where no conversion right exists, such shares will be counted at their stated outstanding amount without discount, unless official filings explicitly specify differently.
The number of outstanding shares will be determined from official company filings or disclosures (e.g., SEC filings). The closing share price on the first trading day will be determined from the primary exchange's official listing page.
If the relevant value falls exactly between two brackets, this market will resolve to the higher range bracket.
The primary resolution source for this market will be official company filings and the primary exchange's official listing page. The market capitalization will be determined through appropriate calculation using the total outstanding shares and the closing price from the first day of trading.
In the event of an interruption in the normal trading session on the specified company's first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that day as the first day of trading for the purposes of this market.**Deep Fission’s IPO pricing and closing market cap reflect investor caution toward an early-stage, pre-revenue small modular reactor (SMR) developer despite nuclear tailwinds from AI data-center power demand.** The company filed its S-1 in mid-May 2026 targeting $24–$26 per share for roughly 6 million shares (plus greenshoe), implying a $1.66–1.7 billion fully diluted valuation at the midpoint to fund its first underground “Gravity” pressurized-water reactor pilot in Kansas under the DOE Reactor Pilot Program.
