OpenAI’s Astra released by…?

Platform comparison

Market context

A **YES** share pays out if OpenAI makes Astra, or a confirmed continuation of the same model, publicly available by 31 October 2026; a **NO** share pays out if it does not. The key point for this market is that OpenAI has already named Astra publicly and described it as its “next major model”, but has still not announced a release date or public access route.[6][12][14]

For readers new to prediction markets, the 4% crowd-implied price is the market’s current estimate of a fairly unlikely outcome, not a statement of fact. That reading is consistent with the public evidence so far: reporting says Astra is still internal, no API, pricing or launch page has appeared, and coverage has repeatedly noted the absence of a confirmed timetable.[2][4][12][17] Comparable OpenAI launches have often been teased before details were finalised, and the company has previously shifted naming at release, which means the branding itself is less informative than whether a public rollout is actually scheduled.[7][14]

The main catalysts to watch are any OpenAI post, product event, or developer update that moves beyond the August 1 disclosure and gives a date, access channel, or renamed successor. A second variable is the reported federal pre-release review process, which one source says could take about 30 days and, if it is genuinely in progress, makes September the earliest plausible public window; that is inference rather than confirmed timing.[1][8] Recent coverage also notes that no official benchmark data, pricing or launch schedule has been published, so traders are mostly waiting for an announcement rather than a technical clue.[4][6]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Market UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
