Trader consensus on Polymarket overwhelmingly favors SpaceX for the largest 2026 IPO by market cap, with an 87.5% implied probability, propelled by its record $210 billion private valuation from recent tender offers and Elon Musk's repeated teases of a Starlink spin-off IPO as early as 2025 amid surging satellite internet subscribers past 4 million. xAI trails at 25.5% on explosive AI growth, including the Grok-3 model's December training announcement and a $24 billion post-money valuation from its Series B, tying into Musk's Tesla ecosystem synergies. OpenAI (5.1%) and Anthropic (5.0%) lag due to unconfirmed restructuring talks, profitability hurdles, and intensifying regulatory scrutiny on AI safety, while laggards like Stripe and Databricks face repeated delays from choppy venture markets. Uncertainties persist as no firm S-1 filings exist, with timelines prone to slippage.

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.
