Market context
The Federal Reserve’s October 2026 meeting will decide whether the upper bound of the target federal funds range is left unchanged, lifted, or, less likely, cut. The crowd is currently pricing only a **1%** chance of a change to the current expectation, which is notably lower than some futures-based reads earlier in the summer that pointed to a meaningful risk of a hike by October.[3][18]
That low figure sits against a backdrop of conflicting but still mostly cautious market signals. Reuters reported in June that traders were pricing about a **60%** chance of a hike by the October meeting, while a later Reuters-linked market read put the October hike probability at **34.1%** and a larger share of the market looking for no move.[3][2] The Fed’s own calendar shows the October FOMC decision will land within the settlement window, so anything that shifts the policy path before then can matter directly for this market.[6]
The main catalysts are upcoming inflation and labour releases, plus the September and October FOMC communications that may clarify whether policymakers are leaning towards holding or tightening. Traders will also watch whether incoming data continue to support the “higher for longer” view described by Reuters and market-monitoring tools, or whether softer growth and inflation numbers restore expectations for no change.[2][3][12] The key dependency is not just the October meeting itself, but whether the run of data between now and then changes the FedWatch-style probabilities enough to move the market off its current near-hold pricing.[12][18]

UK Frequently Asked Questions
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- 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%.
