Fed decisions (Jul–Oct)

Platform comparison

Market context

The Federal Reserve's interest-rate trajectory over the next three months hinges on decisions at FOMC meetings scheduled for late July, mid-September, and late October 2026. The market resolves YES if any single meeting produces a rate cut (a reduction in the upper bound of the target federal funds rate) or a hike. At 0% implied probability on Polymarket, the crowd is pricing near-certainty that rates will remain unchanged across all three sessions. This contrasts with Kalshi's decimal-odds format, which may surface different liquidity patterns on tail outcomes; Betfair and Smarkets typically show tighter spreads on binary outcomes but charge commission rather than relying on order-book spreads, affecting how traders price conviction in a flat-rate scenario.

Historical precedent suggests extended holding periods are common when inflation moderates and labour-market data stabilises. The Fed held rates steady through six consecutive meetings in 2015–16 before cutting, and again through multiple sessions in 2018–19. Current economic data—inflation readings, employment figures, and GDP growth—will determine whether the July, September, or October meetings trigger action. The market's zero probability implies traders expect the Fed to maintain the current rate band through all three meetings, a positioning that requires sustained economic stability and no significant shocks to inflation or employment between now and late October.

Traders should monitor the Consumer Price Index releases (scheduled monthly), non-farm payroll reports, and any Fed communications signalling policy shifts. Chair Powell's remarks at Jackson Hole in late August often signal directional intent. Market-implied probability of 0% leaves no room for tail risk; even modest economic deterioration or inflation surprises could shift conviction on alternative platforms where liquidity and fee structures allow faster repricing.

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.
