Kalshi faces legal injunctions and regulatory scrutiny

Prediction market operator Kalshi is facing intensifying legal and regulatory challenges across the United States. In Michigan, an Ingham County Circuit Court judge issued a preliminary injunction prohibiting the company from offering sports-related contracts to state residents. The court noted that Kalshi’s platform allows 18-year-olds to participate, whereas Michigan law requires users to be at least 21. Non-compliance with this order could result in penalties of up to $500,000 per day.

Beyond state-level enforcement, Kalshi is navigating broader legal disputes regarding its classification. While state regulators in places like New Jersey and Nevada argue the platform functions as illegal sports betting, Kalshi maintains its products are federally regulated event contracts under the Commodity Futures Trading Commission (CFTC). The company is currently preparing for potential Supreme Court involvement following legal battles over whether state or federal law takes precedence.

In other developments, Kalshi has expanded its offerings to include regulated crypto derivatives, such as perpetual futures for BNB and Bitcoin. However, the company also faces private litigation; FlightAware has sued Kalshi in federal court, alleging the platform used its data and trademark without permission to settle wagers on flight cancellations. Despite these legal hurdles, Kalshi has seen significant growth in web traffic and trading volume, with monthly notional trading reaching approximately $40 billion in August.
