Another Fed rate hike in 2026 priced at 80.5% on Polymarket, up 2 points, on $873K traded

Fed hike probability moves higher

Polymarket put the probability of another Fed rate hike in 2026 at 80.5%, up 2 percentage points, with $873K traded, in the supplied market update published Oct 19, 2026, at 10:24 PM ET.

The accompanying news summary identified no significant new platform headline in the preceding 30 minutes. It described search results as recirculating material already handled that day, leaving no fresh reported catalyst for the probability move.

Reading the market snapshot

According to predictionbubbles.net, its finance board reports market-implied probabilities, changes over the previous 24 hours and total traded volume where available. The site refreshes its data every 15 minutes, while trading on the underlying venues continues between updates.

The board covered 192 open finance markets: 20 on Kalshi and 172 on Polymarket. According to predictionbubbles.net, the largest by traded volume at its latest refresh was Polymarket’s contract on unchanged Fed interest rates after the October 2026 meeting, with $14.4M traded.

That October decision contract addresses a different question from whether another hike occurs in 2026. Its volume therefore provides context on trading activity, not a directly comparable probability. PredictionBubbles also cautions that related contracts across venues can differ in wording, settlement rules and deadlines.

What it means for prediction markets

• The reported shift is toward another hike: the 80.5% reading represents a 2-percentage-point increase, not confirmation of a Fed decision.
• The catalyst remains unidentified: the supplied news review offers no new headline explaining the repricing.
• Volume and probability measure different things: $873K is reported trading volume, not a separate measure of the likelihood of a hike.
• Contract scope matters: an October meeting outcome and a broader 2026 hike outcome should not be treated as interchangeable.
