FINMA warns of risks from Anthropic’s AI tool, impacting IPO outlook

Switzerland’s financial regulator FINMA raised alarms over Anthropic’s AI tool Mythos, citing severe risks to financial systems. On Polymarket, the prediction for Anthropic’s IPO market cap to land between $100B and $200B by December 31, 2027, sits at 0.6% YES.

Market reaction

The FINMA warning introduces regulatory uncertainty that could weigh on Anthropic’s market perception. The risk Mythos poses to financial infrastructure is now the dominant concern, and traders may anticipate tighter scrutiny from other regulators affecting Anthropic’s market cap projections. The $100B–$200B market cap prediction is priced at 0.6% YES, unchanged from yesterday but down from 1% earlier this week.

Why it matters

Trading volume at just $21 in USDC over the past 24 hours. Liquidity is thin enough that $55 could shift the odds by 5 percentage points, making this market highly susceptible to small trades. The lack of movement suggests traders are waiting for more regulatory clarity before placing large bets.

What to watch

Regulatory headwinds could dampen Anthropic’s IPO prospects. Buying YES shares at 0.6¢ is a high-risk play with outsized returns if regulatory concerns fade and market cap expectations recover. Current sentiment is skeptical, and a YES bet requires belief that Anthropic can navigate FINMA-style pushback from multiple jurisdictions. Watch for statements from US and UK regulators in particular; any sign of a coordinated regulatory approach could move these odds further.
