Myth one: “prediction markets aren’t gambling, they’re trading”
That line has been doing a lot of work for a lot of platforms, and a US federal appeals court just took a chunk out of it. In late September, the Sixth Circuit held that Kalshi’s sports-event contracts are not swaps under the Commodity Exchange Act, which means they don’t sit inside the CFTC’s exclusive jurisdiction, which means state gambling regulators get a say. Days later, Brazil moved to dismantle the regulated online betting market it had only just built. Two events, one lesson: in the debate over prediction markets vs sports betting, the label on the product matters far less than the law of the place you’re sitting in.
Here’s what each thing actually is, what the rulings said, and why an Indian reader should care about a court in Cincinnati.
Prediction markets vs sports betting: the real difference
The short version: a prediction market is a marketplace where you trade contracts against other participants, and a sportsbook is a counterparty that prices a bet and takes the other side of it. The economics overlap heavily. The plumbing does not.
Event contracts explained
An event contract is a binary instrument tied to a real-world outcome. It settles at a fixed value if the event happens and at zero if it doesn’t. If a contract on “Team A wins the match” trades at 60 cents and settles at $1, the buyer collects 40 cents of profit per contract; the person who sold it at 60 cents loses that amount. The price itself reads as a probability: 60 cents implies roughly a 60% chance.
The feature that platforms lean on is tradability. You can sell a position before the event resolves, at whatever the market will pay. The exchange’s revenue comes from fees and spread rather than from being on the losing side of your bet. Prices move because participants disagree, not because a risk desk adjusted a line.
Traditional sports wagering
A licensed sportsbook sets the odds and carries the risk. Decimal odds of 1.80 mean ₹100 returns ₹180 including stake. Across a two-way market, the bookmaker’s prices add up to more than 100% implied probability, and that excess is the margin, or overround. It is the sportsbook’s equivalent of a house edge, and it is why the book profits over time regardless of which side you back.
Neither model removes the cost of participating. A prediction market charges fees and makes you find someone willing to take your price; a sportsbook builds its margin into the odds. In both, most participants lose money over a long enough horizon.
| Feature | Prediction markets (event contracts) | Licensed sportsbooks |
|---|---|---|
| Who you’re up against | Other traders on the exchange | The operator itself |
| How the price is set | Order book, supply and demand | Odds compilers and risk management |
| Operator revenue | Trading and settlement fees | Built-in margin on the odds |
| Exit before the result | Yes, sell your position at market price | Only if cash-out is offered, at the book’s price |
| Typical regulator (US) | Claimed federal: the CFTC | State gaming commissions |
| Product range | Elections, economics, weather, sport | Sport and racing markets |
Kalshi ruling explained: what the Sixth Circuit actually decided
Kalshi is a CFTC-designated exchange, and its legal argument has been consistent: its sports-event contracts are federally regulated derivatives, so state gambling laws are pre-empted. The Sixth Circuit disagreed on the first step. In its consolidated appeal covering Ohio and Tennessee, the court held that “Kalshi’s sports-event contracts do not constitute swaps as defined in the CEA and thus do not fall within the scope of the CFTC’s exclusive jurisdiction.” You can read the decision itself if you want the reasoning in full.
The practical outcome was split before the appeal and tidy after it. A Tennessee district court had granted Kalshi a preliminary injunction against state officials in February; an Ohio judge had refused one. The Sixth Circuit affirmed Ohio and vacated the Tennessee injunction. It also lined up with the Ninth Circuit, which reached the same conclusion on the swaps question.
What that does not mean: Kalshi has not been shut down, and this is not a final nationwide verdict. These were preliminary injunction fights, further review remains possible, and the CFTC has signalled that dedicated rules for sports-event contracts could land within a couple of months. What it does mean is that the “we’re a derivatives exchange, state law doesn’t apply to us” shield is now failing in two federal circuits, and state regulators have fresh authority to act.
So, is Kalshi legal? As a federally designated contract market, yes. Whether its sports contracts are lawful in a given US state is exactly the question the courts are still chewing on. For Indian residents the answer is simpler: it is not an Indian-regulated venue, and nothing in these rulings changes that.
Brazil’s online betting ban: regulation in reverse
Brazil spent years building the opposite of a grey market. Fixed-odds betting was legalised in 2018, and a full licensing regime went live at the start of 2025 with paid licences, tax obligations and compliance rules. Then, less than two years after launch, the government moved to dismantle it.
This is the part worth sitting with. Brazil’s reversal was not aimed at offshore pirates operating in the dark; it hit the operators that had paid to come into the light. The implementation details and timelines were still being argued over as the news broke, so anyone with money on a Brazilian platform should be checking the current official position rather than a news summary.
Two implications stand out. First, a ban on online wagering doesn’t pause to ask what you call your product. An event contract on a football match looks a lot like a bet on a football match to a legislature that has decided it wants neither, so prediction-market operators get no quiet carve-out. Second, prohibition rarely deletes demand; it relocates it. The predictable consequence is traffic drifting to unlicensed offshore sites with no local recourse, slower payouts and no obligation to honour anything. Players lose the protections, not the temptation.
Legal status: who licenses what, and where
Prediction market regulations
Event contracts are regulated as financial products where they’re regulated at all. In the US that means CFTC oversight of designated contract markets, with the open question being whether sports outcomes belong in that category or in gambling law. Most other jurisdictions have never written a rule for them, which leaves platforms arguing from analogy to derivatives trading and regulators free to reach for existing gambling statutes.
Sports betting licences
Licensed sportsbooks live in a far more settled world: a gaming authority issues a licence, imposes KYC, advertising limits, responsible gambling tools and tax collection, and can revoke it. The UK, Malta, several US states and, until this reversal, Brazil all run versions of that model. It’s slower and more expensive for operators, and it’s the reason a player has someone to complain to.
India sits in a third category. Betting and gambling are state subjects, so the rules have always varied, and the Promotion and Regulation of Online Gaming Act, 2025 prohibits online money gaming at the national level while supporting e-sports and casual online games. There is no SEBI-recognised venue offering sports event contracts to retail Indian traders, and no Indian licensing route for a prediction market. Winnings from online gaming, where they arise, are taxable with TDS applying on net winnings, and that is informational rather than tax advice. If an offshore platform tells you it’s “a trading app, not betting”, the Kalshi litigation is a useful reminder of how much weight that sentence carries.
What event contract betting’s bumpy month signals
Three trends are visible in these two stories, and neither was an isolated accident. The same weekend brought Florida widening its sweepstakes casino crackdown and a sweeping Pennsylvania bill proposing changes across sports betting, iGaming and fantasy contests.
- Regulatory arbitrage is closing. Describing a wager as a financial instrument bought time, not permanence. Courts are now examining the economics of the product instead of the label on it.
- Clearer lines, written by rulemakers. If the CFTC publishes specific rules for sports-event contracts, the category stops being defined by litigation and starts being defined on paper, with whatever restrictions come attached.
- Policy can reverse fast. Brazil shows a licensed market can be unwound in under two years. Legality on the day you deposit is not a guarantee of legality on the day you withdraw.
For a player, the practical takeaways are unglamorous. Know which regulator stands behind the platform holding your money, because “CFTC-regulated exchange” and “licensed sportsbook” and “offshore site with a flashy app” are three very different levels of protection. Withdraw balances you aren’t actively using. Complete KYC early, since verification problems surface at exactly the moment a market is being wound down. And treat prediction markets with the same discipline as any wager: the fees and spread are a real cost, being right about probability is harder than it looks, and no amount of market structure converts a negative-expectation activity into income.
If you do participate where it’s legal to do so, set deposit and loss limits before you start, keep it to money you can afford to lose, and use self-exclusion or cool-off tools if it stops being entertainment. Help is available in India through organisations that support problem gambling.
Frequently asked questions
What are prediction markets?
Marketplaces where participants trade binary contracts on real-world outcomes. A contract settles at full value if the event happens and zero if it doesn’t, and its price reflects the market’s implied probability. Positions can usually be sold before the event resolves.
How do prediction markets differ from sports betting?
In a prediction market you trade against other participants and the exchange earns fees. With a sportsbook, the operator sets the odds, takes the other side of your bet and earns a built-in margin. Different mechanics, same core problem of beating a priced market.
Is Kalshi legal?
Kalshi is a CFTC-designated exchange, but the Sixth and Ninth Circuits have both held that its sports-event contracts are not swaps under the Commodity Exchange Act, which opens the door to state gambling law. The question is unresolved and varies by state. It is not available as a regulated option for Indian residents.
Why did Brazil ban online betting?
Brazil moved to dismantle its regulated online betting market less than two years after licensing began. The policy detail was still developing as the decision was announced, so check the current official position before assuming any Brazil-facing platform can legally hold your funds.
