GPT-6 released by…?

Platform comparison

Market context

OpenAI has not publicly released a model explicitly named GPT-6, and the best-known adjacent event was the April 2026 launch of GPT-5.5, which some observers had expected to be the next numbered release instead. That matters for this market because the contract only settles “Yes” if a publicly accessible GPT-6 appears before the end of 2025, so any private testing, internal preview, or renamed intermediary model would not count under the rules. [1][12][18]

The main historical frame is that OpenAI has often shipped major model updates in stages, with broader availability following earlier limited access, so traders tend to separate an announcement from true public release. In the current case, recent commentary has repeatedly noted that OpenAI had no published architecture, parameter count, pricing, or launch date for GPT-6, and that the model expected by some watchers was instead released as GPT-5.5 in April 2026. That leaves the crowd’s 0% YES price aligned with the absence of any public GPT-6 commitment before the settlement window. [1][12][16][18]

For catalysts, the market hinges on three things: an official OpenAI announcement naming GPT-6, a distribution channel that is plainly public, and timing that fits the contract’s deadline. A closed beta, enterprise-only rollout, or waiting-list that does not amount to general public access would not be enough. The regulatory overlay also matters for access: German GlüStV rules can affect whether a prediction market is offered locally, US CFTC reach shapes how a venue is structured for US users, and “no-KYC up to $1,500” generally means a low-friction onboarding path where smaller positions may be allowed without full identity verification, though higher activity typically triggers checks.

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 Tax UK has a different geo footprint.

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 Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
