Fed decisions (Jun-Sep)

Platform comparison

Market context

The market bets on whether the Federal Reserve will raise the upper bound of its target federal funds rate across three upcoming FOMC meetings in June, July, and September 2026. With the crowd-implied probability of a qualifying cut at 0%, traders are effectively pricing in a scenario where rates either hold steady or rise, reflecting the Fed’s recent hawkish pivot under new Chair Kevin Warsh.

Historically, a 0% probability for cuts aligns with periods of elevated inflation and geopolitical stress, such as the 2022–2023 tightening cycle. In June 2026, the Fed’s dot plot flipped from expecting cuts to projecting at least one hike by year-end, with nine of 18 officials now anticipating tighter policy [6][8]. This mirrors past inflection points where market expectations for easing were abandoned amid inflation spikes, notably when the median year-end rate projection rose from 3.4% to 3.8% [6][8].

Traders should monitor the July 28–29 and September 15–16 FOMC outcomes, alongside CME Fed funds futures, which currently show an 80% expectation for a September hike [2]. Renewed Middle East tensions, particularly Iran-related conflicts, have already pushed September hike odds to approximately 70% [5]. The June meeting minutes confirmed no cuts until early 2027, reinforcing the absence of downward pressure [5]. Key catalysts include inflation data releases and Warsh’s post-meeting remarks, which will shape whether the 0% cut probability holds or shifts.

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.
