Next Claude Sonnet released by 2026?

Platform comparison

Market context

Anthropic has just deprecated its original Claude Sonnet 4 and Opus 4 models on 15 June 2026, creating urgent pressure for a public successor before the settlement window closes in July 2026[4]. This deprecation is not a soft sunset; API calls using pinned identifiers will fail immediately, forcing production applications to migrate or break[4]. The market’s 82% YES probability reflects the high likelihood that Anthropic will launch a new Sonnet variant to replace the retired models before the deadline.

Historically, Anthropic has released Sonnet updates roughly every six to eight months: Claude 3.5 Sonnet arrived in June 2024, Claude 3.7 Sonnet in February 2025, and Claude Sonnet 4.6 in February 2026[1][5]. Following this pattern, a Sonnet 4.7 or 5.0 release is plausible by mid-2026, aligning with the crowd’s confidence[2]. The recent release of Claude Opus 4.8 in May 2026 suggests the company is actively rolling out upgrades, increasing the chance a Sonnet variant follows soon[3].

Traders should monitor Anthropic’s official announcements and API update logs for any mention of a Sonnet 4.7, 5.0, or similar variant becoming generally available[6]. The migration deadline for deprecated models ends in eight weeks, making a public launch before late July 2026 highly probable[4]. Any delay in releasing a qualifying Sonnet model would directly threaten the YES outcome, so watch for press releases or platform docs confirming public accessibility[7].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
