The Polymarket contract “Trump signs housing bill by end of July?” saw its YES price collapse by 31.8 percentage points over the past 24 hours, dropping from 33.0% to 1.2% as of July 11, 2026. This sharp decline in market-implied probability contrasts with substantial whale buying activity during the same period.
Whales collectively purchased $10K worth of YES contracts and sold only $462, resulting in a net inflow of $9K into YES positions. Fourteen unique whale wallets participated, indicating concentrated interest from large traders. Despite this, the overall 24-hour volume on Polymarket for this market was $36K, while lifetime volume remains at $10K with 22 unique traders, highlighting relatively low overall engagement.
Notably, the whale flow diverged from the price movement, signaling a disconnect between large trader behavior and the broader market sentiment reflected in the price. Moreover, the Polymarket Breaking YES price at 1.2% significantly differs from the Polydata on-chain mid-price of 56.5%, underscoring a sharp discrepancy between market feeds.
The combination of a steep price drop and strong whale buying indicates a complex dynamic in market expectations surrounding the likelihood of Trump signing the housing bill by the end of July.
