Fed Decision in October?

Platform comparison

Market context

The October 2026 FOMC meeting will set the upper bound of the federal funds target range, and this market settles on the size of any change versus the pre-meeting level. With the crowd currently implying only 1% for YES, the base case is effectively no move, so a programmatic trader would treat any shift in pricing as a sparse-event re-hedge rather than a normal directional swing. [5][6]

For context, comparable rate markets have moved sharply when labour or inflation data changed the path of policy. Reuters reported in June that short-term rate traders were pricing about a 60% chance of a hike by the October meeting, while other market monitors later showed the balance shifting back towards no change; the gap between these readings is a reminder that the event price can be sensitive to each macro print. [4][7] More broadly, the Federal Reserve’s own 2026 calendar places the October meeting on 27–28 October, with the policy announcement following on 28 October, so any bot or conditional order logic should key off that timestamp rather than the broader month. [5][14]

The main catalysts are the inflation and labour releases that land before the meeting, plus any guidance from the Fed speakers who shape expectations in the final stretch. Traders using automated tooling typically watch the CME FedWatch odds, compare them with Polymarket’s live price, and only adjust exposure when the probability of a hike or cut materially re-rates after a data surprise. Reuters’ June coverage and CME-based market reads both point to how quickly the market can reprice once the data flow turns. [4][12]

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

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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%.
