Polymarket Moves to Time-Weighted Prices Following Exploit
Following months of unheeded warnings from onchain analysts, a brief "five-second trick" allowed traders to drain millions from Polymarket. To combat this vulnerability, the leading decentralized prediction market is officially moving to time-weighted prices. The structural change is designed to make artificial price pushes too costly for malicious actors to execute successfully. For traders looking to adapt their strategies to these shifting platform mechanics, predictionmarketstools.com provides essential tracking resources.
Kalshi Faces Mounting Legal and Regulatory Pressure
As blockchain markets adjust their technical infrastructure, regulated platform Kalshi is fighting a multi-front legal battle. On July 31, New York sued Kalshi over an alleged illegal gambling operation, escalating a clash between state gambling laws and federally regulated prediction markets. The situation intensified on August 4 when a New York judge denied a CFTC motion to halt the state's enforcement action, though the federal regulator is permitted to renew its request before Judge Victor Marrero.
The regulatory scrutiny extends beyond state borders. Democratic lawmakers are currently urging federal regulators to ban wildfire event contracts, arguing that betting on natural disasters creates dangerous incentives for arson, insider trading, and disaster profiteering.
CLARITY Act Odds Plummet as Trump Media Exits Sector
Political and legislative markets are also seeing significant repricing. On Kalshi, the implied probability of the CLARITY Act passing this year has collapsed. After Senator John Thune skipped a cloture filing, the platform's Sept. 1 enactment contract now trades at just 2 cents, with traders pushing the likelihood of passage firmly into 2027.
Meanwhile, Truth Social's parent company is abandoning its prediction market ventures. Under new leadership, Trump Media is unwinding two major Crypto.com deals to pivot its focus toward media, data licensing, and a planned merger with fusion energy company TAE.
