Next Claude Opus released on 2026?

Platform comparison

Market context

Anthropic has already made a new Opus model publicly available, so the market is now trading on whether another **new Opus release** lands before the 31 July 2026 settlement cut-off. Anthropic’s own Opus page shows a May 2026 launch date, and later release notes indicate Opus 4.7 and Opus 4.8 were both generally available across Claude products, the API and major cloud channels, which is the sort of broad public access this market requires.[2][3][6]

The recent cadence matters more than the headline model name. Public timelines in the results show Opus versions arriving in quick succession through spring and summer 2026, including 4.7 on 16 April and 4.8 on 28 May, with a further July 2026 entry on a public Claude timeline, so traders will watch for another Anthropic post, model card, or API release note before month-end.[7][1][5] In practice, the earlier flow into this market came from low-friction funding routes: fast deposits, cheap on-ramp fees, and easy withdrawals via SEPA, Klarna or USDC tend to support tighter books, while slower fiat rails can leave a 0% market thin even when the underlying event looks active.
