Fed Decision in October?

Platform comparison

Market context

The next FOMC decision in October will matter because this market settles on the change in the upper bound of the federal funds target range versus the level in place before the meeting, with any non-standard move rounded up to the nearest 25 basis points for settlement. At present, the crowd is assigning only 1% to a positive outcome, which is far below recent futures-style pricing that has treated October as a live meeting for a possible hike, rather than the base case.[1][4][16]

That low probability sits against a year of repeated holds and a still-wide gap between official guidance and market pricing. The Fed kept rates at 3.50%–3.75% at its July 2026 meeting, while Reuters reported short-term rate traders then priced roughly a 60% chance of a hike by October.[4][16] Earlier comparable episodes show how quickly pricing can re-rate when inflation or labour data change: after a prior Fed move, rate futures briefly shifted to favour another October adjustment, and in late 2025 the same contract type had priced an October cut at 86% immediately after a different decision.[8][11] For this market, that history suggests the 1% crowd price is reading October as an almost-no-change event, despite the contract’s binary settlement.

Catalysts to watch are the FOMC calendar, the September meeting and statement, the October 27–28 meeting itself, and any fresh dot-plot or press-conference signalling on the policy path.[6][15] Macro releases between now and then, especially inflation and payrolls, will be the main drivers of repricing, because they shape whether traders expect the Fed to stay on hold or move 25 basis points. For crypto, the transmission runs through USDC liquidity, BTC and ETH funding conditions, and the broader risk bid: a surprise hike would likely tighten dollar funding and weigh on leveraged crypto positioning, while a hold would leave the market focused on growth and liquidity rather than immediate policy restraint.[1][6]

Methodology

This page reads Fed Decision in October? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

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%.
