(Anthropic) ## How this market settles If Anthropic confirms an IPO before Jan 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 Jan 1, 2027. ## Evidence you can inspect _These labels describe how a claim relates to the question.

No individual review. It rests on 30 claims from 10 publishers; anything not reported in those sources is not represented here. The report recorded 4 resolution risks, listed with this brief. - The end date metadata shows 2027-01-01T04:59:00Z but the description says 'before Jan 1, 2027', creating a potential timezone ambiguity of ~5 hours around midnight UTC on January 1, 2027. - The description does not specify which securities exchanges qualify for ticker assignment (e.g., does OTC or foreign exchange listing count?) - No official source is specified for confirming IPO pricing or ticker assignment beyond SEC filings. - 'Confirms an IPO' in the description is slightly broader language than the three specific criteria listed, which could cause disputes if Anthropic announces but does not yet meet any of the three listed criteria. ## Publication history - Published 9 November 2026; research dated 9 November 2026. - Published 5 November 2026; research dated 5 November 2026. ## Since the previous brief Compared with research dated 5 November 2026.
