Anthropic IPO by 2027?

Platform comparison

Market context

Anthropic would need to complete a public listing on a US exchange and have its shares open for trading before the market’s deadline for this contract to resolve **Yes**. The company confidentially filed its IPO prospectus with the SEC in June 2026, which means the process is live, but no final pricing date has been announced and confidential filings do not commit the issuer to a timetable.[9][13]

The 0% crowd-implied probability is consistent with how IPO markets usually price in delay risk until a public S-1, roadshow dates and exchange listing confirmation appear. CNBC and other recent reporting say Anthropic could come as soon as October 2026, but that remains conditional; market commentary also points to a typical three- to six-month review cycle after confidential filing, leaving room for slippage if SEC comments, market conditions or underwriting plans push the deal back.[1][5][10]

For traders, the main catalysts are a public registration statement on EDGAR, any announcement of the roadshow window, and a formal exchange notice from Nasdaq or the NYSE. In crypto terms, the event is still an off-chain equity listing, but it settles on-chain in USDC, so flows will mostly reflect how participants position around the deadline rather than any direct BTC or ETH linkage unless broader risk appetite or funding conditions shift sharply.[6][9]

Methodology

This page reads Anthropic IPO by 2027? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
