Largest IPO by market cap in 2026?
7 live outcomes · highest priced: OpenAI at <1% · first close Dec 31, 2026 · $6.6M total volume
About this event
This event tracks which company will complete an Initial Public Offering in 2026 and record the highest market capitalization in U.S. dollars based on its first-day closing share price. Markets evaluate individual candidate companies.
How the outcomes relate
The event contains individual markets for candidate companies. Because the rules specify that resolution goes to the single company with the highest first-day market capitalization (with alphabetical tie-breaking), at most one company can resolve Yes.
How it resolves
Each market evaluates whether a specific company completes an IPO between January 1 and December 31, 2026, 11:59 PM ET, and secures the highest market capitalization based on total outstanding shares multiplied by the official closing price on its first trading day. Non-USD figures convert via the Federal Reserve H.10 reference rate. A company may resolve to No early if it becomes unable to complete an IPO due to an acquisition, merger, or absorption by a publicly traded entity. If a tie occurs, the company whose listed name comes first alphabetically resolves Yes.
Key dates

Resolution source
The primary exchange’s official listing page, with currency conversions using the U.S. Federal Reserve Board’s H.10 foreign exchange reference rate.
