2026 be the hottest year on record priced at 80.5% on Polymarket, up 2.5 points, on $718K traded

Polymarket’s contract on whether 2026 will be the hottest year on record was priced at 80.5%, up 2.5 probability points, with $718K traded, in the supplied market update published Oct 18, 2026, at 2:39 AM ET.

The figures show a higher market-implied probability, but the supplied material does not identify a fresh climate development behind the move. The accompanying news summary reported no significant new platform headline in the preceding 15 minutes, with search results limited to recirculated items from Oct. 17.

Reading the repricing

According to predictionbubbles.net, its movers dashboard compares prices over 24 hours and refreshes every 15 minutes, using prices from Polymarket and Kalshi. The supplied page records a venue-data snapshot taken on 18 Oct 2026, 06:17 UTC.

The dashboard orders markets by their absolute change in probability points, rather than their relative percentage change. It covers 2,037 markets lasting longer than 14 days and excludes markets without a valid day-old price comparison, according to predictionbubbles.net.

What the figures leave open

The supplied dashboard text explains the methodology but does not display the hottest-year contract’s individual entry. Its 80.5% price, 2.5-point rise and $718K trading figure come from the supplied headline; the material does not specify the period covered by that trading total or provide the contract’s settlement criteria.

That limits what can be concluded about the move. Trading volume and price movement describe different aspects of a market, and neither the headline nor the dashboard excerpt establishes why traders raised the price.

What it means for prediction markets

• The change is 2.5 probability points, not a 2.5% relative increase. The quoted price indicates that traders favor the record-temperature outcome.
• $718K traded is activity context, not a measure of available liquidity. The supplied material does not show order-book depth.
• No catalyst is established. The quiet 15-minute news window does not explain a move measured against a 24-hour dashboard framework.
• Settlement details remain important. The supplied material does not identify the temperature benchmark or resolution rules for the contract.
