Next Claude Sonnet released by 2026?

Platform comparison

Market context

The real-world event is whether Anthropic will publicly launch its next Claude Sonnet model before the settlement deadline of 31 July 2026. With a current crowd-implied probability of 92% YES, the market reflects strong confidence that the next Sonnet variant—such as Sonnet 4.7 or 5.0—will be made available to the general public within this window.

Historically, Anthropic has maintained a tight release cadence for Sonnet models, with Sonnet 3.5 arriving in July 2024, Sonnet 3.7 in February 2025, and Sonnet 4.6 in February 2026[1][5]. The deprecation of Sonnet 4 on 15 June 2026 further signals an imminent successor, as users were given only eight weeks to migrate before API calls failed[4]. Comparable patterns suggest a new Sonnet release is likely in the first half of 2026, aligning with the 92% probability.

Traders should monitor Anthropic’s official announcements, particularly any scheduled updates to the Claude Platform or API, and watch for mentions of Sonnet 4.7 or 5.0 in transparency reports[7]. Recent community speculation points to a potential Sonnet 5 release in January 2026, though an updated Sonnet 4 variant could arrive sooner[2]. The regulatory context includes German GlüStV implications for gambling-style markets and US CFTC reach over prediction contracts; the “no-KYC up to $1,500” threshold means this market remains accessible to UK and EU traders without identity verification, provided they stay under the limit.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
