Prediction market platform Kalshi is asking federal regulators to let traders buy event contracts with borrowed funds, a move that would bring Wall Street-style leverage into a market already drawing fire from state attorneys general and federal courts.
Kalshi Klear, the company's internal clearing house, filed with the Commodity Futures Trading Commission on Tuesday seeking approval to offer margin trading on its event contracts, CNBC reported. If the CFTC signs off, Kalshi would become the first regulated U.S. exchange to let users trade prediction market contracts on leverage, putting up a fraction of the cost and borrowing the rest.
Every event contract on a regulated U.S. exchange is currently backed dollar-for-dollar with cash. Kalshi's filing would change that model for the first time, opening the door to amplified gains, and amplified losses, on bets tied to real-world outcomes like elections, economic data, and geopolitical events.
Kalshi framed the request as a play for bigger, more sophisticated traders. In a memo provided to CNBC, the company argued that leverage would make longer-dated prediction markets more attractive to institutional investors. The logic is straightforward: hedge funds, trading firms, and asset managers are accustomed to margin trading on traditional equities and derivatives. Without it, tying up large sums of cash in a prediction contract that might not settle for months is an expensive proposition.
Kalshi already offers leverage on its perpetual futures contracts, a separate product line. But the company has not received approval to extend margin to its core prediction market offerings until now filing for it.
The platform's volume has surged over the past year, driven primarily by retail traders wagering on sports-related contracts. That retail boom has drawn significant legal attention. New York filed a sweeping lawsuit seeking billions from the company, and other states have followed with their own challenges.
But Kalshi's margin push is aimed at a different customer base entirely. Under the proposed rules, only self-clearing members with direct relationships with Kalshi Klear would gain access to leveraged contracts. Those members would need to meet certain capital requirements, thresholds the filing does not publicly specify.
One notable feature of Kalshi's proposal: the capital required to maintain a leveraged position would increase as a contract approaches its expiration date. The closer an event gets to resolution, the more cash a trader would need to post. That structure mirrors risk-management practices in traditional derivatives markets, where margin calls escalate as settlement nears and price swings become more volatile.
A Kalshi spokesperson told CNBC the company would not offer margin on its sports event contracts, its culture markets, or its so-called "mention" markets, categories that have drawn the heaviest regulatory scrutiny. The exclusion of sports contracts is notable given that Connecticut sued Kalshi over those very offerings, calling them unlicensed gambling.
The carve-out suggests Kalshi is trying to thread a needle: expand its product for institutional clients while steering clear of the categories that state regulators have targeted most aggressively.
Kalshi is not the only prediction market eyeing leverage. Bloomberg News reported in July that Polymarket, Kalshi's chief rival, made moves to obtain regulatory licenses that would eventually let it offer margin trading on event contracts in the United States. Whether Polymarket has secured any approvals remains unclear from available reporting.
The race to offer margin underscores how quickly the prediction market industry has matured, and how aggressively its biggest players are pushing to look and function like traditional financial exchanges. That ambition has put them on a collision course with state gambling regulators who view many of these contracts as wagers, not financial instruments.
Federal courts have produced mixed results on that question. A federal judge blocked Minnesota's prediction market ban, siding with Kalshi and the CFTC's authority over event contracts. But the Ninth Circuit ruled against prediction markets in a Nevada case, setting up a potential Supreme Court showdown over who regulates these products.
Adding margin to the mix raises the stakes considerably. Leveraged trading magnifies risk. When a trader puts down twenty cents to control a dollar's worth of contracts, a wrong bet doesn't just cost the initial stake, it can generate losses that exceed it. Traditional brokerages manage that risk with decades of infrastructure, regulatory oversight, and margin-call protocols. Whether a prediction market platform, one that lets 18-year-olds place bets that licensed sportsbooks won't touch, is ready for that responsibility is a question the CFTC will now have to answer.
One detail worth noting: CNBC disclosed that it has a commercial relationship with Kalshi that includes customer acquisition and a minority investment in the company. The size of that investment was not specified. The disclosure does not undermine the reporting, but readers evaluating coverage of Kalshi from that outlet should be aware of the financial connection.
The CFTC has not publicly responded to the filing or indicated a timeline for review. Kalshi Klear's submission is available as a public document through the company's regulatory filings page.
Prediction markets have earned their place as a legitimate financial tool. But letting traders bet on borrowed money before the basic question of who regulates these platforms is even settled looks less like innovation and more like building the second floor before the foundation has set.
