Fed Decision in October?

Platform comparison

Market context

Polymarket is pricing this October FOMC outcome at **1% YES**, so the contract is effectively saying a change in the upper bound of the federal funds target range next month is still a tail event. On Polymarket, that view is expressed through conditional tokens settled in **USDC on Polygon**, with the market resolving to the size of the rate move versus the level before the October 2026 meeting; if the Fed delivers an unlisted step, the move is rounded up to the nearest 25 basis points. The relevant official meeting date is the October 27–28 FOMC meeting, with the decision due on 28 October.[6][15]

That is much lower than the broader rates backdrop traders are watching. CME’s FedWatch tool has recently shown materially higher odds of a move by the October 2026 meeting, with Reuters reporting around a **60%** chance of a hike by then in June, while later commentary and market summaries have also pointed to a growing probability of a higher target rate by late 2026.[4][2][3] For comparison, a high-60s “no change” price on Polymarket for the October meeting would still leave a small but non-zero tail for a surprise hike or cut, which is why a 1% change contract can persist even when futures markets are noisier.[7][19]

For traders, the main catalysts are the summer and early-autumn data releases that feed the Fed’s reaction function: payrolls, inflation prints, and any shift in financial conditions before the late-October meeting. The market will also track FOMC communications and the official calendar for any signs of a policy pivot, because October is a standard meeting but not a dot-plot month, so the decision itself will matter more than projections.[6][15] If incoming data re-accelerates inflation or labour-market tightness, rates pricing can reprice quickly; if not, the current 1% price reflects how far the contract is from a routine hold.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Is this market available outside the US?
