Infiniti Intelligence Hourly Briefing — Oct 28, 2026 · 6:24 PM ET

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.

A Polymarket contract on a 5kt meteor strike in 2026 was priced at an implied probability of 11.5%, down 0.5 percentage points, with $315K traded in the supplied market snapshot dated Oct 28, 2026, at 6:24 PM ET.

The accompanying news summary identified no significant new platform headline in the preceding 30 minutes. It said search results resurfaced material already used that day, assigned to website-only batches or excluded by a banned list. That leaves no fresh reported catalyst in the supplied material to explain the price decline.

What the available data establishes

According to PredictionBubbles, its market data comes from Polymarket and Kalshi and refreshes every 15 minutes, although trading on the venues is continuous. The service defines probability changes as percentage-point moves over the last 24 hours and reports total traded volume where the venue publishes it.

The supplied PredictionBubbles page explains those conventions but does not display the meteor contract itself. The headline provides its price, change and volume; the material does not include the contract’s full wording or resolution criteria. Those omissions limit what can be concluded about precisely which event would qualify for a payout.

What it means for prediction markets

• A modest downward move: The 0.5-point decline leaves the quoted probability at 11.5%; the supplied reporting does not establish why it moved.
• Volume is not a fresh inflow: The $315K figure is reported as traded volume, not money traded during the latest news window.
• Resolution details remain important: Without the contract rules, readers cannot verify how the 5kt threshold or confirmation of a qualifying strike would be assessed.
