Next Claude Sonnet released by 2026?

Platform comparison

Market context

Anthropic’s deprecation of its original Sonnet 4 and Opus 4 models on 15 June 2026 has created a clear operational gap for developers, pushing the market to anticipate a public Sonnet successor before the settlement deadline of 31 July 2026. With crowd-implied probability at 94% YES, traders are betting the next Sonnet variant—whether named Sonnet 4.7, 5.0, or another Sonnet iteration—will be launched and publicly accessible within the remaining 35 days.

Historically, Anthropic has filled similar gaps swiftly: after deprecating earlier models in 2024, it released Claude 3.5 Sonnet just two months later in July 2024, and followed with Claude 3.7 Sonnet in February 2025. The pattern shows a roughly six-to-eight-month cadence between major Sonnet updates, but the recent 4.6 release in February 2026 and the imminent 4.8 Opus launch in May suggest accelerated iteration. This compressed timeline supports the high probability that a Sonnet 4.7 or 5.0 will emerge before the deadline, especially given the urgency created by the 15 June API break.

Traders should monitor Anthropic’s official announcements, particularly any press releases tied to the upcoming Opus 4.8 launch on 28 May 2026, which often include parallel Sonnet updates. The company’s transparency hub and developer forums are key sources for early signals, as seen when Sonnet 4.6 was announced alongside Opus 4.7 in February. With the settlement window closing in late July, the market is leaning on the catalyst of an imminent Sonnet 4.7 or 5.0 release, likely announced within the next two weeks to allow time for public deployment.

FAQ

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
