Two stories are reshaping online gambling in 2026. The first is American: prediction-market platforms such as Kalshi and Polymarket offer event contracts, including on sports, under federal commodities law, while states argue those contracts are sports betting that needs a state license. The second is global: governments are raising gambling taxes and tightening player protections, from the UK and the Netherlands to Brazil and Sweden.
The legal picture changes by the week. The facts below come from press coverage and industry roundups as of late October 2026, and several tables we found disagreed with each other. Check current status with a gambling-law specialist before relying on any of it.
Prediction Markets: Federal Exchange or State Gambling?
Prediction-market platforms list contracts on elections, economics and, since 2025, sports. Their position is that these are event contracts under the Commodity Exchange Act, overseen by the CFTC. States counter that a contract on a game's outcome is a sports wager and needs a gaming license.
As of late October 2026, reporting describes a fast-moving, split picture: the CFTC has reportedly sent two rules to the White House for review that would classify event contracts as swaps, strengthening its claim to exclusive jurisdiction; the Third Circuit sided with Kalshi while another appeals court ruled that its sports contracts do not meet the legal definition of a swap; and the Supreme Court has so far declined to take the question up immediately. Kalshi is seeking en banc rehearing at the Sixth Circuit after a third consecutive circuit loss (Coin360 summary).
On the ground, enforcement is escalating: Utah sued Kalshi in state court on 20 October and the CFTC then sued to stop Utah enforcing its gambling laws against the platform; Baltimore has sued both Kalshi and Polymarket; and Polymarket has reportedly stopped new sports contracts in Michigan, becoming the fourth prediction-market exchange to block residents of a state from buying them. A bipartisan Senate bill, the Prediction Markets Are Gambling Act, would bar CFTC-registered entities from listing contracts that resemble sports betting, but we could not confirm its status.
Why it matters to builders. If you integrate a prediction market, build on top of one or accept its users, assume availability can change by state overnight. Geofencing and per-state product flags are not optional.
Sweepstakes Casinos: Ban, Tax or Tolerate?
Sweepstakes casinos give players virtual currency that can be converted into prizes, which operators argue keeps them outside gambling law. States are increasingly unpersuaded. One legislative tracker reports that Virginia lawmakers narrowly advanced a bill to legalize online casinos while banning sweepstakes casinos, while Illinois is considering taxing and regulating them under its existing iGaming framework instead (Gambling Insider tracker). The pattern is that states that already license online casinos tend to ban sweepstakes rivals, and states without a licensed market debate regulating them.
UK, Netherlands, Sweden and Brazil: Higher Taxes, Tighter Rules
Industry guides we reviewed report the following, but they are secondary sources, so verify against the regulators before using any figure:
| Market | Reported 2026 change |
|---|---|
| United Kingdom | Remote Gaming Duty raised to 40% of profits from April 2026; slot stake cap of £5 (£2 for ages 18-24); bingo duty abolished from 1 April 2026 |
| Netherlands | Gaming tax at 37.8% of gross gaming result from January 2026; untargeted advertising restricted; CRUKS exclusion register |
| Sweden | Credit-funded gambling banned from April 2026; first five-year licenses expire in October 2026 |
| Brazil | Regulated market with a 13% GGR tax in 2026, reported to rise to 15% by 2028; enforcement and consolidation underway |
| Canada (Alberta) | Competitive iGaming market reported open from 13 July 2026 |
The direction is consistent: governments want licensed, taxed markets, and they are paying for it with tighter player protections and higher operator costs. Margins shrink, so compliance automation and efficient payments matter more.
What Operators and Builders Should Do
1. Treat jurisdiction as a first-class variable. Product availability, odds formats, bonuses and advertising rules should be driven by a per-market configuration, not hard-coded.
2. Invest in identity and affordability. KYC, age checks and source-of-funds checks are tightening everywhere, and regulators increasingly expect them to be proactive rather than reactive.
3. Model the tax hit. A move from low-20s to 37-40% duty changes unit economics; rework bonus budgets and affiliate deals accordingly.
4. Prepare for crypto and stablecoin questions. Many platforms accept or settle in stablecoins; make sure your approach fits the licensing and AML rules in each market. See our overview of stablecoin payments for business.

Frequently Asked Questions
Are prediction markets legal?
It depends on who you ask and where. The CFTC regulates platforms such as Kalshi as federally registered exchanges, while several states say sports event contracts are unlicensed gambling. Courts have ruled both ways, and the issue is not settled.
What is the difference between a prediction market and a sportsbook?
A sportsbook sets odds and takes the other side of your bet under a state gambling license. A prediction market lists event contracts that users trade with each other on an exchange, and the exchange earns fees. Regulators and courts disagree on whether that difference matters for sports contracts.
What is a sweepstakes casino?
A sweepstakes casino lets players use virtual coins that can be won as redeemable prizes, which operators argue avoids gambling law. Some US states are moving to ban such platforms; others are considering taxing and regulating them.
What compliance basics do iGaming platforms need?
Licensing per jurisdiction, geofencing, identity and age verification, anti-money-laundering controls, responsible-gambling tools and, increasingly, affordability checks and advertising limits.
