Market context
The Federal Reserve raising the upper bound of the funds rate at any point in 2026 is the event being priced here, and the market is currently implying **63% YES**, so the favourite is a hike rather than no change. That sits above the broad economist consensus, which is still tilted to the Fed staying on hold through year-end; Reuters’ June poll found nearly 70% of economists expected no move in 2026, while J.P. Morgan and Goldman Sachs both still called for no hike this year in their base cases.[10][1][16]
The comparable-case read is that this market is trading a more hawkish path than many house forecasts, but not wildly so. The Fed’s own June projections showed nine of 19 policymakers expecting at least one hike in 2026, and the July Monetary Policy Report said fed funds futures were pricing the rate about 30bp higher by year-end, close to 4%. That leaves the underdog case as a clean “no hike” outcome if inflation cools or growth softens, while the value angle for YES is that official projections and market pricing have already shifted towards at least one move.[4][2][9]
For traders, the key catalysts are the next inflation prints, the labour market run-rate, and the Fed’s remaining meetings, especially the September, October and December FOMC decisions. The market cannot resolve “No” until after the December 8-9 meeting, so late-year CPI and payroll data matter more than usual, alongside any change in Fed rhetoric about price stability and the path of policy. CNBC reported in June that traders were already pricing at least one hike in 2026 and a better-than-even chance of another by December, which shows how sensitive this market is to each new inflation surprise.[3][18]

Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
UK Frequently Asked Questions
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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%.
