1 Fed rate hike happen in 2026 priced at 18.5% on Polymarket, down 3.0 points, on $559K traded

Polymarket’s contract on exactly 1 Fed rate hike in 2026 was priced at 18.5%, down 3.0 percentage points over 24 hours, with $559K traded, according to the supplied PredictionBubbles snapshot. The figures accompanied an Oct 28, 2026 update published at 6:24 PM ET.

A narrower bet on the Fed’s path

The decline reflects a lower market-implied probability of the single-hike outcome. It does not, by itself, show whether traders shifted toward no hikes or multiple hikes: the supplied material does not include prices for those alternatives.

PredictionBubbles’ finance-board summary recorded 187 open markets and $162.3M in traded volume at its Oct. 28, 22:13 UTC crawl. The service aggregates finance and economics contracts from Kalshi and Polymarket, displaying probabilities, 24-hour changes and traded volume.

Snapshot differences matter

The accompanying page text gives a different market count: 194 open contracts, comprising 24 from Kalshi and 170 from Polymarket. Those figures should be distinguished from the crawl summary rather than treated as one consistent snapshot. According to PredictionBubbles, its data refreshes every 15 minutes, while trading on the underlying venues continues between updates.

The page also identifies the Polymarket contract on no Fed rate cuts in 2026 as its highest-volume finance market at the last refresh, with $9.2M traded. That is a separate question from exactly 1 hike; its trading activity does not establish the probability of the single-hike outcome.

PredictionBubbles describes itself as an information service displaying venue-published prices, not a platform that accepts wagers or holds funds. It also cautions that related contracts across venues can differ in wording and resolution rules.

What it means for prediction markets

• The move is outcome-specific: The 3.0-point decline concerns exactly 1 hike in 2026, not the probability of any hike.
• Volume is not certainty: The $559K figure measures total traded volume, not the reliability of the 18.5% probability.
• Timing and terms matter: A 15-minute refresh cycle can leave displayed prices behind live trading, and cross-venue comparisons require checking contract wording and resolution rules.
