Market context
OpenAI has not publicly confirmed a GPT-6 release date, and the market only resolves **Yes** if a model explicitly named GPT-6 becomes broadly available to the public before the end of 2025. That matters because recent OpenAI releases have shown a tendency to ship successor models under different branding or as interim versions, which makes name discipline more important than hype when reading the odds.[1][13][14]
The closest comparable case is the model many observers expected to become GPT-6 but which shipped on 23 April 2026 as **GPT-5.5** instead, with rollout first to paid ChatGPT tiers and then API access the next day.[1][14] That is useful framing for the current **0% yes** price: even where OpenAI has an internal model ready, the public-facing label can still remain within the GPT-5 family. More broadly, the absence of an announced architecture, pricing, or launch date keeps the probability of a 2025 public GPT-6 release extremely low on the information available.[1][12][13]
For traders, the main catalysts are official OpenAI product announcements, release-note updates, and any public schedule changes around model rollout or safety review. OpenAI’s help centre maintains model release notes, so a named entry there would be a strong signal; by contrast, private testing, enterprise-only access, or a rolling waitlist would not satisfy this market’s settlement rule.[10][13] On the market-access side, German **GlüStV** rules can complicate access for users in Germany because prediction markets may be treated as gambling-like products, while the **US CFTC** has broad reach over event contracts that touch US persons or US-facing activity; separately, “**no-KYC up to $1,500**” means a platform can allow relatively small-volume use before identity verification, but that does not remove jurisdictional restrictions or change how this specific market resolves.
Methodology
This overview of GPT-6 released by…? reviews the four comparable platforms from a regulatory perspective: which is accessible in your jurisdiction, where KYC kicks in, how the platform is classified by your country of residence. Live probability is the Polymarket mid; comparison columns show regulatory status, KYC thresholds and settlement options for each platform.

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. Is Polymarket Legal in Canada has a different geo footprint.
- Do I need to KYC for Is Polymarket Legal in Canada?
- 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.
- What happens during a tax audit?
- You're responsible for documenting your trades. Is Polymarket Legal in Canada 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.
- 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).
