Polymarket traders surge on Anthropic as 2026's top IPO bet
Polymarket traders are wagering Anthropic will become 2026's largest IPO, with the AI lab now at 45% probability and rising 37 percentage points in a week, according to Binance. Anthropic sits just below SpaceX at 55% in the market's ranking. Separately, Cointribune reported traders are pricing an October 2026 listing for the IPO. Anthropic, the company behind Claude, has attracted prediction-market interest as it moves toward a public debut. Specific volume figures and market depth data were not provided in the available source material.
The 37-point climb matters because it tests whether prediction markets can produce stable, tradable prices on long-duration corporate events. For Polymarket, Anthropic joins Paramount-Skydance and Tesla-SpaceX as a third major corporate-event contract where retail flow must prove sticky beyond headline spikes. Traders face wide spreads and stale prices in thin IPO markets, and the absence of published fillable orders or post-trade size means no one can verify actual liquidity.
The ranking flip against SpaceX also raises a measurement problem: the market's methodology for weighing rival IPOs is opaque, so a probability shift may reflect new money or simply churn from existing holders. Polymarket's credibility as a venue for tech-debut pricing depends on whether this contract generates repeat participation or fades like prior single-name experiments.
Kalshi's recent AI IPO and space market experiments, alongside its Paramount-Skydance and Tesla-SpaceX merger contracts, show both major regulated venues vying to make corporate events a repeatable vertical for retail pricing.
