Kalshi Fights NY Gambling Enforcement Following Record $9B Month
Kalshi appealed to the Second Circuit today after a New York federal judge denied the platform's request to block state gambling officials from enforcing local laws against its sports event contracts. The legal escalation comes immediately on the heels of a massive growth period for the platform. According to DefiLlama data, Kalshi's June trading volume topped $9 billion, driven significantly by the expanded FIFA World Cup.
Traders Sue Polymarket Over Rule Change
Meanwhile, Polymarket is facing its own legal challenges. Two users, William Wood and Thomas Bush, filed a complaint in the Supreme Court of the State of New York against the prediction market platform, its holding entities, and CEO Shayne Coplan. The plaintiffs allege that Polymarket wrongly resolved a market concerning whether "Strategy" would sell Bitcoin by adding a rule after the fact, effectively turning their winning "Yes" bet into a loss.
Despite these domestic legal hurdles and existing geoblocks, US users continue to dominate Polymarket's political betting markets, according to recent data from Allium.
Global Regulatory Headwinds
Regulatory scrutiny is also tightening abroad. The European Securities and Markets Authority (ESMA) warned this week that many event contracts may already fall under the EU's existing ban on marketing binary options to retail investors. The regulator emphasized that companies cannot circumvent financial rules simply by rebranding binary-style products. For traders navigating these shifting global regulations, utilizing reliable prediction market tools is essential to track platform compliance and market availability.
