Polymarket Moves to Time-Weighted Prices to Halt Exploit
Following months of public warnings from onchain analysts, Polymarket is officially changing its pricing mechanism to stop a five-second trick that allowed traders to drain millions from the prediction market. The platform is transitioning to time-weighted prices, a structural shift designed to make artificial price pushes too costly for bad actors to execute profitably. For traders looking to analyze how these structural changes impact liquidity, utilizing the data trackers at predictionmarketstools.com is essential for navigating the updated order books.
Trump Media Scraps Prediction Market Plans
In a major strategic pivot, Truth Social's parent company is unwinding its prediction market ventures and two major Crypto.com deals. Under new leadership, Trump Media is abandoning its crypto treasury strategy to focus entirely on media, data licensing, and an upcoming planned merger with the fusion energy company TAE.
Regulatory Heat Mounts for Kalshi and Event Contracts
As blockchain platforms adjust their technical frameworks, regulated markets are facing severe political headwinds. Democratic lawmakers are actively urging federal regulators to step in, arguing that wildfire event contracts create risks of arson, insider trading, and disaster profiteering. The push for a CFTC ban on these specific contracts adds to the mounting pressure on platforms like Kalshi.
Kalshi is already fighting a multi-front legal battle regarding its operations. On August 4, a New York judge denied a CFTC motion to halt the state's enforcement action against the platform, leaving New York's recent lawsuit over an alleged illegal gambling operation firmly in place while the CFTC prepares to renew its request before Judge Victor Marrero.
Meanwhile, political bettors on Kalshi are adjusting their timelines for crypto legislation. Traders have pushed the implied probability of the CLARITY Act's passage into 2027 after Senator John Thune skipped a crucial cloture filing. Consequently, Kalshi's September 1 contract plummeted to just 2 cents, while prices for enactment before January 1, 2028, ticked upward.
