Fed decisions (Jun-Sep)

Platform comparison

Market context

The Federal Reserve held its benchmark rate steady at 3.50%–3.75% in June 2026, but the accompanying dot plot revealed a sharp pivot from expected cuts to anticipated hikes, with nine of eighteen officials now projecting at least one increase before year-end[2][5]. This hawkish reversal stems from inflation surging to 4.2% in May—the highest in three years—driven by Middle East conflict disrupting global energy supplies and pushing core PCE inflation to 3.4%[3][7]. Historically, such a sudden shift in the Fed’s internal projections, particularly when inflation remains well above the 2% target, has preceded rate increases within three to six months, making the current 0% crowd-implied probability for a cut appear misaligned with official sentiment[2][5].

Traders should monitor the July 28–29 FOMC meeting for any further clarification on the inflation outlook, followed by the September 15–16 decision, which CME Group’s FedWatch tool now prices at a 49.5% chance of a hike[1][6]. The primary catalyst is renewed geopolitical tension: President Trump declared a temporary Iran peace deal “over” and hinted at imminent strikes, pushing Brent Crude above $80 and lifting September hike odds to roughly 70%[3]. With unemployment steady and the Fed’s focus squarely on inflation risks, any escalation in the Strait of Hormuz or further oil price spikes will likely cement a qualifying hike rather than a cut in the June–September window[3][7].

Methodology

This page tracks Fed decisions (Jun-Sep) across four political prediction venues. Live odds come from the Polymarket order book (the deepest political prediction-market book). Kalshi is the CFTC-regulated US alternative, Betfair the established UK sports-exchange with politics markets, Manifold the open play-money variant. For users geo-blocked from Polymarket directly, brokers like Trump Prediction provide a 0%-fee route into the same order book.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
