SpaceX commands an overwhelming 86.5% implied probability as the largest 2026 IPO by market cap, driven by its soaring private valuation—recently pegged at $350 billion in secondary trades—and explosive Starlink subscriber growth surpassing 5 million. Elon Musk's recent comments on a potential Starlink spin-off IPO in 2025-2026, contingent on Starship orbital success, have amplified trader optimism amid accelerating Starship test flights. xAI trails at 25.5% following its $6 billion funding round valuing it at $24 billion post-money, fueled by Grok AI advancements and Musk's cross-company synergies. Lower odds for Anthropic (5.2%) and OpenAI (5.1%) reflect smaller valuations ($18-40 billion range) and regulatory scrutiny on AI firms, while legacy unicorns like Stripe lag without firm IPO signals. Key watch: Starship Flight 6 in late 2025.

This market will resolve to a company that completes an Initial Public Offering (IPO) between January 1 and December 31, 2026, 11:59 PM ET.
Market capitalization is defined as the total number of outstanding shares multiplied by the closing share price on the first trading day.
If two or more companies have exactly equal highest closing market capitalizations, this market will resolve to the company whose listed name comes first alphabetically.
Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used.
In case the respective company's primary exchange’s official listing page does not report in U.S. dollars, it will be converted to U.S. dollars using the U.S. Federal Reserve Board’s H.10 foreign exchange reference rate for the relevant currency pair on the company’s first trading day (https://www.federalreserve.gov/releases/h10/). If no such rate is available for the relevant trading day, the most recent previously published rate will be used. If the relevant currency is not listed, another credible exchange rate source will be used.
A listed company may resolve to "No" as soon as it becomes unable to complete an IPO, including due to acquisition, merger, or absorption by an entity that is already publicly traded.
In the event of an interruption in the course of the normal trading session on the respective companies’ 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 as the first day of trading for purposes of this market.
