Fed Decision in July?

Platform comparison

Market context

The Federal Open Market Committee convenes on 29 July 2026 to determine whether the upper bound of the target federal funds rate, currently 3.75%, shifts by any basis points. This market resolves on the specific change in that upper bound versus the pre-meeting level, with the crowd currently pricing a zero-change outcome at 100% certainty, implying no hike or cut is expected.

Historically, July meetings have rarely triggered rate adjustments when inflation data remains volatile but growth moderates, mirroring the June 2026 unanimous hold at 3.50%–3.75% under Chair Kevin Warsh [4]. While CME Fed funds futures previously showed a 40% hike probability earlier in June, that figure dropped to roughly 30% by late June as traders trimmed bets following data showing inflation hitting a three-year peak [1]. The current 0% probability aligns with the June FOMC minutes, which indicated no rate cuts until early 2027 and a split outlook on tightening, though renewed Middle East tensions have since lifted September hike odds to 70% [2].

Programmatic traders should monitor the 2:00 PM ET rate announcement and Chair Warsh’s 2:30 PM ET press conference on 29 July, as conditional orders often trigger on the precise basis point change rather than the direction alone. Key catalysts include the upcoming inflation gauge and any geopolitical disruptions, with the Fed’s own dot plot now leaning toward at least one rise before year-end rather than a cut [4]. Recent reporting confirms traders view a September hike as the likely scenario, reinforcing the July hold expectation [1]. Automated strategies should watch for deviations from the 25-basis-point rounding rule if the Fed announces an unlisted rate level.

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

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.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
