Prediction markets have become a jurisdictional fight. Federal regulators and U.S. states are now openly contesting who has the authority to oversee these markets — and, by extension, who controls a fast-growing new segment of trading activity.

A federal appeals court ruled this week that Kalshi’s sports contracts are federally regulated derivatives, not gambling. The CFTC, in parallel, sued three states to block their enforcement actions.
Polymarket began rolling out its largest infrastructure upgrade to date. Binance Wallet added direct access to prediction markets for retail users.
Product and distribution moved forward. The legal fight moved into the courts.
What Moved the Markets This Week
Courts and Regulators Take the Lead
The legal fight over prediction markets advanced on several fronts this week. The Third Circuit ruled that Kalshi's sports contracts fall under derivatives law, not state gambling statutes limiting states' ability to block them. The ruling is preliminary, not a final determination on the merits, but it buys Kalshi time.
The CFTC and the Department of Justice separately filed suit against Arizona, Connecticut, and Illinois, arguing that state enforcement actions are preempted by federal law. More cases are in motion.
The Ninth Circuit is set to hear consolidated arguments involving Kalshi, Robinhood, and Crypto.com on April 16. The dispute now centers on which authority regulates them.
Polymarket Rebuilds its Core
Polymarket is rolling out what it calls its largest infrastructure upgrade since launch. The platform is replacing its core collateral asset with a proprietary token — Polymarket USD — backed 1:1 by USDC held in reserve.
The move cuts reliance on bridged assets and the risks tied to third-party infrastructure. Polymarket is also rebuilding its trading engine to reduce costs and improve execution speed. The upgrade adds support for multi-signature wallets, a requirement for institutional users.
The timing is deliberate. A fully controlled collateral layer and an upgraded trading system are preconditions for a regulated U.S. relaunch and broader institutional access.

Retail Gets in — And Gets Credited
Access to prediction markets is expanding beyond dedicated platforms. Binance Wallet introduced a feature this week allowing users to take positions on real-world events directly from the app, lowering the barrier for retail participants. The rollout is part of a broader push to reach users who don't want specialized setup.
Kalshi's founders, meanwhile, continue to argue that retail users are not just participants — they are a key source of predictive accuracy. CEO Tarek Mansour said the platform's performance comes from a broad base of users "trading out of their garage," not from traditional finance professionals.
More users now have direct access, and platforms are actively positioning retail traders as central to price formation.
Quote of the Week
Kalshi CEO Tarek Mansour appeared on The Axios Show on April 7, addressing insider trading enforcement on prediction markets:
"It's our responsibility as an exchange and the responsibility of regulators to identify these bad actors, as well as to detect and deter their actions. You punish them when you find someone who did something bad. It's a good thing."
Mansour added that if there were a yes/no contract on Kalshi about whether the CFTC would open an insider trading investigation within the next year, he would expect it to trade at "yes."
Number of the Week
$30 million. That's how much has been traded on Kalshi's market tracking whether tech layoffs in 2026 will exceed last year's total.
The contract is growing fast and has already surpassed some of the platform's major entertainment markets — a sign of rising demand for contracts tied to economic data.
The Friction of the Week
The central tension this week is between federal regulatory expansion and state authority over consumer protection. The CFTC is not just defending its jurisdiction in court — it is actively suing states, filing for injunctions, and using the Third Circuit ruling as a template.
Its argument is consistent: prediction market contracts are federally regulated derivatives, and states cannot recharacterize them as gambling to justify enforcement.
States are not retreating. Connecticut AG William Tong called the contracts "plainly unlicensed illegal gambling." Over 34 states filed amicus briefs asserting their regulatory authority. A bipartisan coalition of more than 20 senators has urged the CFTC to stay out of the litigation entirely.

The platforms sit in the middle. They argue they are regulated exchanges operating under federal law — while simultaneously running markets on war, political outcomes, and now tech layoffs.
Mansour welcomed federal enforcement against bad actors this week. But the same federal authority Kalshi is relying on to defeat state gambling laws is also drafting rules on margin trading, insider trading, and public-interest prohibitions — rules that could constrain which contracts the platforms can list at all.
The CFTC is Kalshi's shield and its regulator at the same time. How much authority it chooses to exercise on both fronts is the question neither side has answered.
Bottom Line
The regulatory question was not resolved this week. The Third Circuit sided with Kalshi. The CFTC escalated by suing three states. More rulings are coming, and the outcome will likely be shaped across multiple jurisdictions rather than by any single decision.
The market is not waiting. Platforms are rebuilding infrastructure, expanding distribution, and listing contracts tied to economic data alongside politics and sports.
Prediction markets are now running on two tracks: legal definitions are being tested in court, while usage continues to grow.
