Will Anthropic’s valuation hit 2027 by December 31?

Market context

Anthropic’s private market valuation would need to reach the stated threshold in Nasdaq Private Market’s daily published NPM Price before 31 December 2026. The current 12% yes price implies the market is treating that outcome as a low-probability tail event, even though Anthropic has already moved quickly from a $61.5 billion valuation in March 2025 to $380 billion in its February 2026 Series G, according to the company’s own announcement. That step-up matters because prediction markets on private valuations tend to reprice around formal rounds, not just headline rumours, and the NPM pricing lag means traders are effectively betting on what is recorded, not what is reported in secondary chatter.

Comparable cases suggest the path to settlement is less about ambition than timing and documentation. Public reporting from Bloomberg on 13 May said Anthropic was exploring a further raise at more than $900 billion, while Sacra and other tracking sites have already flagged early talks above $900 billion. If those talks turn into an executed round, the valuation question becomes mechanical: a single NPM print at or above the threshold is enough. Until then, the market is exposed to the usual private-market frictions — delayed pricing updates, cross-checking of trade data, and the possibility that a headline number never appears in NPM.

For traders, the key catalysts are any financing announcement, the timing of a signed term sheet, and whether Nasdaq Private Market publishes a new price shortly after a transaction closes. Because the contract settles in USDC, the main crypto linkage is indirect: broader BTC and ETH risk appetite can influence on-chain liquidity and stablecoin flows, but the event itself turns on a private equity mark rather than spot crypto. The relevant schedule risk is the NPM publication window, since prices are only updated once daily on the following trading day and unresolved data can keep the market open into early January.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

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.

FAQ

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
