FOMC Polymarket Odds: A Rate Hold Regains the Edge in October Pricing

MACROECONOMICSFOMC Polymarket Odds: A RateHold Regains the Edge inOctober Pricing45IMPORTANCECLOSED3NEWS MEDIA4PIECESSep 30, 2026 10:08blockboard.net

Polymarket pricing on the October 27-28 Federal Reserve meeting moved from favoring a 25-basis-point hike to favoring no change over the same week. Across the six updates, the hold side ranged from 57% to 66%, while hike odds fell from the mid-60s to the mid-30s or low-40s. The shift left the October decision unresolved, with some coverage also noting attention to later meetings or to Bitcoin.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

What has changed in practice is the market’s balance on the October 27-28 decision: earlier snapshots had a hike in front, and later snapshots put no change ahead. What has not changed is that the contract still leaves both outcomes active, and one update also kept an eye on higher cumulative hike odds by December. That means the October contract is still a pricing screen, not a settled policy outcome.
