How it resolves

Kalshi's rule, word for word
(Each outcome is its own contract. This is the rule for the favourite, Before Mar 1, 2027; the others read the same way with their own outcome.) If Anthropic confirms an IPO before Mar 1, 2027, then the market resolves to Yes. An IPO is confirmed if 1) the SEC declares the company's Form S-1 effective OR 2) the IPO is priced OR 3) a securities exchange has assigned a ticker to it. As long as any of those events occur, the market will immediately resolve to Yes, even if the company does not start trading until after Mar 1, 2027.
