FOMC Polymarket Odds: A Rate Hold Regains the Edge in October Pricing
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 this rests on
What it means
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.
Market reaction
The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
