Analysis
The market is pricing in a 72% probability of Anthropic releasing Mythos by September 2026, but the extremely thin liquidity ($68 open interest) and wide 9¢ spread raise questions about price reliability. The dramatic yield asymmetry—651% for No versus 109% for Yes—suggests the No side is severely underpriced relative to tail risk, indicating potential mispricing or that sophisticated traders view a Mythos release as quite unlikely despite the headline probability. The 7-point price decline over a week combined with 137 days to expiry and low volume ($68 in 24h) suggests this market lacks conviction and could see sharp repricing on any credible Anthropic announcement.
Resolution rules
If Anthropic releases A model called Mythos before Sep 1, 2026, then the market resolves to Yes.
