A federal judge’s refusal to block New York gambling enforcement against Kalshi is the week’s clearest signal that prediction markets’ U.S. expansion may be decided as much in state courts and legislatures as in Washington. Reuters, via MarketScreener, reports that the judge denied Kalshi’s bid for a preliminary injunction, ruling that the Commodity Exchange Act did not preempt New York gambling laws for Kalshi’s sports-event contracts. For market watchers, that raises the stakes around a central question: when does a federally regulated event contract become a state-regulated sports bet?
Kalshi Takes Hits in New York and Michigan
The New York ruling comes as Kalshi is already constrained in Michigan. Axios Detroit reports that the company began blocking Michigan users from sports-related markets after a state court order temporarily barred it from offering sports event contracts there.
Together, the cases point to a fragmented legal map for sports-linked prediction markets. Even if a platform operates under federal commodities rules, states are asserting authority when contracts resemble gambling products. That could slow rollout plans, limit liquidity in certain jurisdictions, and force platforms to segment offerings by state.
Polymarket Tries to Rebuild U.S. Trust
AP reports that Polymarket is trying to re-enter the U.S. conversation with a more compliance-forward posture, including hires, partnerships, and a separate CFTC-regulated platform. The story frames the effort as a trust-rebuilding campaign after years of controversy tied to its offshore exchange.
That matters because Polymarket has remained a major brand in prediction markets, but its U.S. opportunity depends on convincing regulators, partners, and users that it can operate inside the lines. Its push also contrasts with Kalshi’s court fights: one major player is emphasizing re-regulation and institutional credibility, while another is testing the boundaries of federal preemption.
North Carolina Considers Legal Recognition
Axios Raleigh reports that North Carolina’s proposed state budget would authorize CFTC-licensed prediction markets and tax their net trading fee revenue at 6%. Gambling-policy opponents are already criticizing the proposal.
If enacted, the measure would be notable because it treats federally licensed prediction markets as a legitimate category rather than simply as gambling to be blocked. That would give platforms a clearer path in one state, even as New York and Michigan move in the opposite direction.
Manipulation Risk Gets a Spotlight
WIRED reports that Spotify confirmed artificial streaming after a Kalshi trader flagged suspicious chart activity. The episode highlights a structural risk for markets tied to third-party metrics: if payouts depend on external rankings or data feeds, participants may have incentives to influence those inputs.
Why it matters
Prediction markets are moving from niche product to regulatory battleground. The immediate story is not just demand or volume; it is whether platforms can win durable legal status, protect market integrity, and avoid being reclassified as gambling state by state.
