Prediction markets experience explosive growth, but also new legal challenges
Jeffrey Bandman, a former Commodity Futures Trading Commission official who led Kalshi’s regulatory strategy from 2019 and has returned after a two-year hiatus, told me that the founders were determined to build the business in close cooperation with regulators. “They understood early on that taking regulation seriously could be a competitive advantage,” he said.

TL;DR
- Kalshi, a leader in prediction markets, is experiencing rapid growth, with monthly trading volumes surpassing $37 billion and a valuation reaching $40 billion.
- The company's business model relies on trading fees from binary events contracts, which are priced based on the probability of an outcome.
- Kalshi's regulatory status is contested, with states arguing its offerings constitute gambling, while the company and the CFTC maintain they are derivatives.
- Numerous lawsuits have been filed by state attorneys general and tribes, with some seeking substantial penalties, and cases are advancing through federal appeals courts.
- The legal challenges may culminate in a Supreme Court ruling that will determine the future of prediction markets and the CFTC's regulatory authority over them.
