Next Claude Opus released on 2026?

Platform comparison

Market context

Anthropic’s next **Claude Opus** release is the first public, generally available model with an explicit Opus name after Opus 4.8, so the market resolves only when that branding appears on a launch page or equivalent public announcement. At present, Opus 4.8 is the latest official Opus model on Anthropic’s site, which means a “yes” needs a clearly named successor rather than a Sonnet, Haiku, or other family update.[1][6]

For comparable cases, Anthropic has been shipping Opus upgrades in fairly short cycles: Opus 4.7 was announced as generally available on 16 April 2026, and Opus 4.8 followed on 28 May 2026, roughly six weeks later.[2][6] That cadence matters for market reading because a steady sequence of numbered Opus launches makes a near-term successor plausible, but the market should still ignore naming drift or adjacent releases. For a programmatic approach, many traders would key off Anthropic’s news page and model-overview endpoints, then trigger conditional orders when a public page includes “Opus” in the model name and confirms general availability.

The main catalysts are official product posts, model docs, and cross-platform availability notices, because Anthropic has typically published launches alongside API identifiers and cloud rollout details.[1][2][6] A recent wrinkle is that the current Opus page was updated on 28 May 2026, so any fresh change there would be a strong signal to monitor closely.[1] For a bot, the practical watchlist is: new Anthropic news items, changes to the Claude models overview, and launch pages that move from preview language to “generally available” or “available today”.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Bot UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.
