The prediction market on whether July 2026 will be the hottest month on record experienced a dramatic shift, with the YES contract price climbing 51.0 percentage points over the past 24 hours to reach 80.5% from an estimated 29.5% a day earlier.
This sharp repricing was supported by whale activity, which aligned with the price move. Over the same period, 33 unique whales collectively bought $16K and sold $4K, resulting in a net inflow of $11K into YES positions. The overall 24-hour trading volume on Polymarket for this contract was $17K, indicating that whales accounted for the majority of recent market turnover.
Since inception, the market has seen $28K in lifetime volume and engaged 124 unique traders, reflecting sustained interest in this climate-related question. The strong whale buying alongside the rapid price increase suggests growing conviction among large traders that July 2026 will set a new temperature record.
The combined evidence of a 51.0 pp price jump and $11K net whale inflow reinforces the market’s heightened expectation for an unprecedented heat record next July, marking a significant update in climate event odds on Polymarket.
