Next Claude Opus released by 2026?

Platform comparison

Market context

The real-world event is whether Anthropic will publicly release its next model explicitly named Claude Opus before the end of 2026. In prediction markets, a YES share pays out if the event occurs, while a NO share pays out if it does not; here, the crowd assigns a 95% chance to the release happening, reflecting strong confidence in Anthropic’s timeline.

Historically, Anthropic has maintained a rapid flagship cadence, with Claude Opus 4.8 launched on 28 May 2026 and Opus 4.7 preceding it in late 2025[1][2]. Given the typical six-to-eight-week cycle for new flagship models in 2026, a point-bump Opus refresh is expected within weeks rather than months, making a 2026 release highly probable[3]. Past suspensions, such as the June 2026 halt of Mythos-class models due to export controls, have not disrupted the Opus line, which remains the stable general-purpose flagship[3].

Traders should monitor Anthropic’s official announcements for any confirmation of an Opus 4.9 or Opus 5.0, as well as updates on the suspended Fable 5 and Mythos 5, which may influence release sequencing[3]. The API availability pattern—where new Opus versions appear immediately on the Claude API and major cloud platforms like Amazon Bedrock and Google Vertex AI—offers an early signal[1][4]. With no confirmed next model named as of late June 2026, the next move is likely a safeguarded Opus refresh, aligning with the 95% market probability[3].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
