Fed Decision in September?

Platform comparison

Market context

The Federal Reserve’s September meeting is now a straight handicapper’s call on whether the upper bound of the target range moves from 3.5% to 3.75%, and the market is treating a hike as a deep underdog with only a 1% implied chance. That pricing sits well below the broader prediction-market and media consensus, which has leaned towards no change or, at most, a modest tightening move later in the year rather than by September.[16][19][20]

Historically, September FOMC meetings matter because they arrive with a full policy statement, fresh Summary of Economic Projections and the dot plot, so traders often use them to confirm or reverse the summer narrative.[1][3][7] The latest policy backdrop is already more divided than in earlier 2026 meetings: the Fed kept rates at 3.5%-3.75% in July, but the vote showed dissent and the balance of views has shifted more hawkish at the margin.[2][15] For a market this one-sided, the value question is whether the crowd is over-anchored to a hold and underweights a surprise hike if inflation data stays firm.

The main catalysts are the August and early-September data run, any shift in inflation or labour readings, and the meeting itself on 15-16 September, with the decision due at 2:00 p.m. Eastern on 16 September and the press conference following at 2:30 p.m. Eastern.[1][3][7] Recent coverage has also highlighted a stronger hawkish constituency inside the Fed, with some officials already signalling that inflation still leaves room for tighter policy, so traders will watch whether incoming data validates that line or forces the committee back to neutral.[5][15]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win 2026, which mirrors the Polymarket order book directly.

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.
