Grok 4.6 released by 2026?

Platform comparison

Market context

SpaceX's xAI division must release Grok 4.6 or a direct successor variant to the general public by mid-August 2026 for this market to settle affirmatively. The current 0% crowd probability reflects scepticism about the timeline; xAI has not yet publicly committed to a Grok 4.6 roadmap or release window, and the company has historically prioritised X platform integration over broad public availability schedules.

xAI's release cadence offers limited precedent for forecasting. Grok 3 launched in March 2024 as an X Premium exclusive; Grok 4 arrived in December 2024 with gradual rollout to X users and limited API access. The jump from 4.0 to 4.5 occurred within months, suggesting xAI can iterate rapidly once a major version ships, but no pattern yet exists for predicting when point-release variants reach general public status. Comparable frontier labs—OpenAI, Anthropic, Google—typically space major releases 6–12 months apart, though xAI has shown willingness to compress timelines when engineering capacity permits.

Traders should monitor xAI's public statements at earnings calls, X announcements, and developer documentation for roadmap hints. Elon Musk's commentary on AI development velocity and xAI's computational scaling (tied to Starlink and Tesla infrastructure) will signal engineering bandwidth. Any announcement of Grok 4.5 general release or API expansion would materially shift near-term probability, as it would clarify whether xAI intends to push 4.6 within the settlement window or defer to 2027. Funding rate movements on prediction markets tracking competing models (Claude, GPT-5) may also correlate with xAI momentum shifts.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

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%.
