Fed decisions (Apr-Jul)

Platform comparison

Market context

The Federal Open Market Committee will convene three times between April and July 2026 to decide whether to lower the upper bound of the target federal funds rate, currently sitting at 3.75%. This market tests if a qualifying cut occurs across the April 28–29, June 16–17, or July 28–29 meetings, with the crowd-implied probability of such an event currently at zero per cent.

Historical precedent from late 2025 shows the Fed executed a series of cuts before halting in December, leaving rates unchanged at 3.50%–3.75% through March and April 2026 as inflationary pressures muddied the outlook [1][2]. The zero per cent probability reflects a market consensus that the Fed will maintain this pause to balance its dual mandate, mirroring the stability seen in the June 17 statement where the target range was explicitly maintained at 3.50%–3.75% [4]. Traders comparing platforms should note that Polymarket displays decimal odds while Kalshi and Betfair often emphasise implied probabilities, and fee structures diverge significantly between these books, with Kalshi requiring strict KYC that Polymarket does not enforce for this specific market type.

Key catalysts include the upcoming FOMC statements and any shifts in inflation data that could force a policy adjustment, though derivatives markets currently suggest only a 60% chance of a hike by year-end rather than a cut [2]. Investors must monitor the June and July meeting calendars closely, as any deviation from the 3.50%–3.75% range would resolve the market, while the current stance of holding rates steady remains the dominant narrative supported by recent FOMC introductory statements [3]. The divergence in fee structures between Smarkets and Kalshi further impacts net returns for traders betting on this outcome, with Smarkets offering lower commissions but Kalshi providing deeper liquidity for federal funds rate contracts.

Methodology

This page compares Fed decisions (Apr-Jul) specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Kalshi Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
