How it resolves

Kalshi's rule, word for word
(Each outcome is its own contract. This is the rule for the favourite, Before Jan 1, 2027; the others read the same way with their own outcome.) If Anthropic releases A model called Mythos before Jan 1, 2027, then the market resolves to Yes. Release must be to the public, outside of a closed beta, though limiting it to a high-cost subscription tier is acceptable.
