What Exactly Is a Prediction Market?
Imagine being able to place a bet not just on a football game, but on who will win the next presidential election, whether inflation will hit a certain target, or even whether Congress will pass a specific bill. That’s the basic premise of prediction markets — platforms where participants buy and sell contracts tied to the outcome of real-world events. If you’re right, you profit. If you’re wrong, you lose your stake.
The concept isn’t new. Economists have championed prediction markets for decades as remarkably accurate forecasting tools, arguing that when people put real money on the line, prices reflect genuine collective wisdom. The Iowa Electronic Markets, a small academic platform, has been running political prediction contracts since 1988 with impressive results. But what is new is the emergence of well-funded, commercially ambitious companies pushing these markets into the mainstream — and running headlong into regulators and courts along the way.
Kalshi, the CFTC, and a Legal Showdown
The company most responsible for the current legal drama is Kalshi, a New York-based startup founded in 2018 that bills itself as the first federally regulated prediction market exchange in the United States. Kalshi operates under oversight from the Commodity Futures Trading Commission (CFTC), the same federal agency that regulates futures and derivatives markets for commodities like oil and wheat.
That regulatory relationship has been anything but smooth. In 2022, the CFTC rejected Kalshi’s application to offer contracts on congressional control — essentially letting traders bet on which party would control the Senate or House. The agency argued the contracts were contrary to the public interest, potentially manipulative, and uncomfortably close to illegal gambling. Kalshi sued, and in a significant 2024 ruling, a federal appeals court sided with the company, finding the CFTC had overstepped.
The decision sent shockwaves through the industry. By late 2024, Kalshi had launched election contracts drawing millions of dollars in trading volume, competing directly with offshore platforms like Polymarket, which has processed over $1 billion in political contract trades while operating outside U.S. jurisdiction.
Where Sports Betting Fits In — and Why It Complicates Everything
The legal battles get even messier when sports enter the picture. Kalshi has also pushed to offer contracts on NFL game outcomes, which puts it in direct conflict with a very different regulatory ecosystem: the state-by-state sports betting industry, which exploded after the Supreme Court struck down a federal prohibition in 2018.
Traditional sportsbooks — companies like DraftKings and FanDuel — operate under state gambling licenses and pay substantial fees and taxes for the privilege. They argue, loudly, that a federally regulated platform offering functionally identical products under the CFTC’s lighter touch creates a deeply unfair playing field. Several state attorneys general have backed that argument, and the legal fight over sports event contracts was still active heading into 2025.
The core tension is one of regulatory arbitrage: is a contract on a Super Bowl winner a gambling product governed by state gaming laws, or a financial instrument governed by federal commodity law? The answer changes everything — from tax treatment to consumer protections to who gets to offer it.
The Bigger Picture
Prediction markets sit at an awkward intersection of finance, gambling, and public policy, and American law hasn’t quite figured out what to make of them. Supporters argue they generate genuinely useful information — research has shown prediction market prices often outperform traditional polling and expert forecasting — and that restricting them pushes American traders toward unregulated offshore platforms with far fewer consumer protections.
Critics worry about market manipulation, the normalization of wagering on political outcomes, and the potential for well-resourced traders to distort results that the public treats as credible signals.
What’s clear is that the industry is growing too fast for the legal ambiguity to last much longer. With billions in trading volume, well-funded companies, and a federal appeals court already reshaping the rules, prediction markets are forcing a long-overdue conversation about how the United States draws the line between investing and gambling — and who gets to decide.
