Kalshi, a prediction market platform, has formally asked the Securities and Exchange Commission to slow down Cboe's move into the same space. The request, made to the SEC, targets Cboe's planned entry into event-based trading, a field Kalshi already operates in. It's a direct regulatory challenge from one competitor to another, and it puts the SEC in the middle of a turf war.
The request
The details of Kalshi's filing aren't public. What is clear: Kalshi wants the SEC to intervene before Cboe launches its own prediction products. Cboe, a major exchange operator with decades of trading infrastructure, has been building out its presence in event contracts. Kalshi's move suggests it sees Cboe as a threat to its own business model.
Prediction markets let people trade on the outcome of future events — elections, economic data, even weather. They're not new, but they've gained attention recently as more platforms push into the space. Kalshi has been one of the most active participants, offering contracts on everything from inflation rates to political races.
Why the competition is heating up
Cboe's entry would bring a heavyweight into a market that's still young and lightly regulated. The company has decades of experience running exchanges and handling large volumes. That could pressure smaller players like Kalshi, which relies on a narrower base of traders and a tighter product lineup.
But the fight is also about regulatory advantage. Kalshi has already navigated the SEC's approval process for its own contracts. That process is slow and case-by-case. If Cboe gets a similar green light quickly, it could jump ahead. Kalshi's request to the SEC may be a way to force a more careful review of Cboe's plans, or at least to level the playing field.
What the SEC has to weigh
The SEC's job is to protect investors and ensure orderly markets. With prediction markets, that means deciding whether a given contract looks more like gambling or more like a legitimate financial product. Kalshi's own contracts have been approved before, so the SEC has already taken a view on the product type. But Cboe's scale is different — it brings a much bigger exchange platform and a broader customer base.
There's also the question of whether prediction markets fall under the SEC's jurisdiction at all. Some contracts could be seen as gaming, which might land with the Commodity Futures Trading Commission instead. The SEC hasn't yet said how it will treat Cboe's filing, or Kalshi's request.
What happens next
The SEC has no deadline to respond to Kalshi's request. Cboe hasn't said publicly when it plans to launch its prediction products. The regulatory review could take months, and the outcome will set the pace for everyone else in the space.
For now, Kalshi has put its complaint on the table. The question is whether the SEC treats it as a protective measure or as a competitor's attempt to block a new market entrant. That call won't be quick, but it will shape who gets to run the next generation of event trading.
