“Trump signs housing bill by end of July?” YES price plunges 30.1 pp to 2.4% on Polymarket

The Polymarket contract asking if “Trump signs housing bill by end of July?” saw its YES price collapse by 30.1 percentage points in the last 24 hours, dropping from 32.5% to 2.4% as of the July 11 snapshot. This sharp repricing contrasts significantly with on-chain data, where the Polydata mid-price stands at 56.5%, more than double the Polymarket price.

Volume on the market over the past day reached $28K, a notable figure given the contract’s lifetime volume of just $346 and only seven unique traders involved overall. Despite the steep selloff reflected in the price, whale trading flow diverged from the tape, signaling a disconnect between large traders’ actions and the rapid drop in odds. This divergence suggests that while the market price fell dramatically, whale activity did not confirm the bearish move.

The gap between the Polymarket price and Polydata’s on-chain mid-price, combined with the opposing whale flow, highlights a rare moment where the market’s sentiment and large trader positions are not aligned. Such a divergence raises questions about the underlying drivers of the price collapse and indicates potential volatility or uncertainty in how the market is digesting information about the housing bill’s timeline.

Overall, the 30.1 percentage point decline in YES odds alongside contrasting whale behavior signals unsettled market dynamics and a possible reassessment phase for this contract’s probability.
