Market context
Anthropic, the San Francisco-based AI safety company founded in 2021, has not yet filed for public listing. The question turns on whether the firm will complete an initial public offering and commence trading on a recognised securities exchange by 1 July 2027. The 1% crowd probability reflects the absence of any announced IPO timeline, regulatory filings, or public statements from leadership signalling imminent public markets entry.
Comparable venture-backed software and infrastructure firms typically require 7–10 years to IPO maturity, though timelines vary sharply. OpenAI remains private despite substantial valuation; Databricks, founded in 2013, has not yet listed. Anthropic's founding in 2021 places it within the typical pre-IPO window, yet the absence of filed Form S-1 documentation or SEC pre-filing activity suggests no near-term public markets transition. The 1% reading aligns with base rates for unlisted companies in their third operational year absent explicit IPO signals.
Traders should monitor announcements regarding funding rounds, regulatory engagement with the SEC, and any public statements from Anthropic's board or executives regarding capital structure strategy. Recent reporting from TechCrunch and Bloomberg has covered funding developments but contains no IPO timeline disclosures. The German GlüStV framework and US CFTC reach do not materially affect this market's accessibility; prediction markets on IPO events remain available to UK-domiciled traders under Polymarket's regulatory model. No-KYC access up to £1,500 applies to this market, permitting retail participation without identity verification below that threshold, though larger positions require standard customer due diligence.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
