Imagine being able to buy a contract that pays out if inflation rises above 3 percent next year, or if a particular party wins a congressional seat. That is essentially what prediction markets do, and they have spent years caught in a regulatory no-man’s-land somewhere between Wall Street and Las Vegas. The debate over how to classify them is not just philosophical. It has real consequences for who can operate these platforms, who can participate, and whether the information they generate is treated as useful data or a social harm.
How the Mechanics Actually Work
At their core, prediction markets let participants buy and sell contracts whose value is tied to whether a specific event occurs. A contract might be priced at 60 cents and pay out one dollar if the event happens, or nothing if it does not. That 60-cent price reflects the collective judgment of everyone trading that the event has roughly a 60 percent chance of occurring.
The appeal to economists and researchers has long been that these markets can aggregate scattered private knowledge into a single, legible probability. When many people with different information and incentives put real money behind their views, the resulting price can be more accurate than polls or expert panels alone. Research over the years has generally supported this claim for certain types of events, though the evidence is stronger for some domains (elections, commodity prices) than others.
Platforms like Kalshi, based in the United States, have worked to position their products as financial contracts rather than bets. Kalshi obtained designation as a designated contract market from the Commodity Futures Trading Commission, the federal agency that oversees derivatives markets, which gave it a legal foundation that most offshore betting sites lack. That regulatory status matters because the CFTC operates under a different framework than the state agencies that govern traditional gambling.
Where Gambling Law Enters the Picture
The distinction between a futures contract and a wager is older than the internet, and courts have wrestled with it for well over a century. The rough legal principle is that a futures contract serves an economic purpose beyond the bet itself, such as allowing a farmer to hedge against a drop in crop prices. A wager, by contrast, exists purely for the gamble.
Prediction markets on political events have faced the sharpest scrutiny under this framework. The concern raised by some regulators is that contracts tied to election outcomes serve no obvious hedging function and could affect the events they are supposed to merely predict. Kalshi fought a legal battle with the CFTC over its election contracts, and the dispute drew attention to how unsettled this area of law remains. A federal district court sided with Kalshi in 2024, and the CFTC dropped its appeal in 2025, but the broader regulatory questions were far from resolved. Kalshi’s sports contracts have since drawn state challenges, and federal appeals courts have split: the Third Circuit sided with Kalshi against New Jersey in April 2026, while the Ninth and Sixth Circuits ruled for the states. New Jersey asked the Supreme Court to resolve the split in September 2026. The CFTC, meanwhile, proposed new event-contract rules in June 2026.
State gambling laws add another layer of complexity. Even if a platform clears federal hurdles, it may still face restrictions depending on where its customers live. Polymarket long operated offshore partly to avoid this patchwork of state rules, though it has since acquired a CFTC-licensed exchange and launched a regulated U.S. app.
What It Means for Everyday Participants
For most people, prediction markets are still more of a curiosity than a practical financial tool. Participation limits, liquidity constraints, and regulatory uncertainty have kept them from becoming mainstream in the way that stock trading apps have. Still, interest has grown, and the volume of contracts traded on regulated platforms has increased meaningfully over the past few years.
The information these markets produce does reach a broader audience. During election cycles, journalists and analysts routinely cite prediction market probabilities alongside traditional poll averages. Whether those probabilities are genuinely more reliable, or simply more confident-sounding, is a live debate among researchers.
The regulatory path forward will likely depend on how policymakers answer a foundational question: is a contract on a future event a form of financial infrastructure, a form of entertainment, or something that shifts depending on what the event is? For now, the answer varies by jurisdiction, by agency, and sometimes by which way the wind is blowing in Washington. That ambiguity is both the industry’s biggest obstacle and, in a way, its most compelling selling point.
