Fed rate hike by 2026?

Platform comparison

Market context

The Federal Reserve faces a decision on whether to raise interest rates between mid-December 2025 and the conclusion of its scheduled FOMC meeting in late October 2026. The current 0% crowd probability reflects widespread expectation that rate increases remain off the table during this window, given the Fed's recent pivot toward accommodation and persistent uncertainty over inflation's trajectory. The market's settlement hinges on any upward adjustment to the upper bound of the target federal funds rate, including emergency moves outside regular meeting schedules.

Historical precedent suggests rate hikes become plausible only when inflation accelerates sharply or financial stability risks emerge suddenly. The Fed held rates steady through 2024 and into 2025 after a tightening cycle that began in March 2022. Previous episodes of reversal—such as the 2019 pivot from hiking to cutting—took months to reverse course once conditions shifted. A return to hiking would require either a significant rebound in core inflation above the Fed's 2% target or an external shock severe enough to warrant emergency action, neither of which markets currently price as probable.

Traders should monitor December's inflation data releases, particularly the PCE deflator figures due in January 2026, alongside any Fed communications signalling concern about price pressures. The FOMC's December 2025 meeting statement and Chair Powell's subsequent remarks will set the tone for expectations through the resolution window. Geopolitical developments, labour-market strength, and any financial-stability concerns could rapidly shift probabilities, though current consensus among major forecasters aligns with the market's assessment that rate cuts or holds remain the baseline scenario.

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.

UK Frequently Asked Questions

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

What are the best prediction markets for UK traders in 2026?
