Plain read: Anthropic says it has a locked-down AI tier called Mythos that's too dangerous to release publicly. On April 22 2026 they announced they're investigating whether that tier got breached. On April 23 2026 Anthropic's market valuation hit $1 trillion, overtaking OpenAI — same 24-hour window. If a real breach happened and the market priced it correctly, the 'locked tier' claim is architecturally real. If the market shrugged because investors know the 'gated tier' is mostly regulatory theater (commercial customers get the full capability through side channels), the $1 trillion valuation confirms the claim is performative. This divergence tests which reading is right.
