Traders Sue Polymarket Over Bitcoin Resolution as Kalshi Hits $9B June Volume

by Editorial Team

Polymarket faces a lawsuit over a retroactive rule change on a Strategy Bitcoin sale market, while Kalshi's June trading volume topped $9 billion.


Traders have filed a lawsuit against Polymarket following a controversial resolution regarding a market on Strategy's Bitcoin sale. According to Decrypt, plaintiffs allege the decentralized prediction platform added a rule retroactively, which flipped their winning "Yes" shares into a losing "No" resolution. This legal challenge arrives just days after Allium data revealed that U.S. users continue to dominate Polymarket's political markets, successfully bypassing the platform's geographical blocks.

Kalshi Surges Past $9 Billion in June

While Polymarket battles legal and geographical hurdles, its regulated U.S. competitor is experiencing explosive growth. DefiLlama data shows that Kalshi posted a record-breaking month, topping $9 billion in trading volume in June. The surge was primarily fueled by heightened prediction market activity surrounding the expanded FIFA World Cup.

ESMA Warnings and Supreme Court Rulings

Regulatory landscapes for event contracts are shifting violently on both sides of the Atlantic. The European Securities and Markets Authority (ESMA) issued a stark warning that prediction market event contracts may already violate the bloc's existing ban on marketing binary options to retail investors. The regulator emphasized that firms cannot bypass financial rules simply by rebranding binary-style products as event contracts.

Meanwhile, in the United States, a landmark 6-3 Supreme Court ruling in Trump v. Slaughter has overturned the 91-year-old Humphrey's Executor precedent. This decision clears the path to fire SEC and CFTC commissioners at-will, just as the CLARITY Act nears a floor vote. Concurrently, the SEC, under Chair Paul Atkins, has opened a 60-day comment period on 'Novel' ETF rules. This follows Atkins' May statement pausing launches for over two dozen pending applications covering crypto-asset and prediction-market funds.
