Anthropic Odds Sink in Spacex IPO Race

Prediction markets now give SpaceX ($SPCX) a 66.5% chance of being 2026's largest IPO, more than double Anthropic's 27.6%, according to Polymarket odds tracked on November 3. The gap has widened after reports of a weaker Anthropic valuation target and a looming "high junk" credit rating for the AI startup. Traders are betting Anthropic won't out-value the rocket company's IPO this year.
