New Jersey Petitions US Supreme Court Over Kalshi Case With Bitcoin (BTC) Event Contracts at Stake

New Jersey Takes Kalshi Fight to the Supreme Court

New Jersey's top law-enforcement officials escalated their battle with prediction market platform Kalshi on Wednesday, formally asking the US Supreme Court to decide who regulates sports event contracts traded on federally registered venues. Attorney General Jennifer Davenport and Mary Jo Flaherty, interim director of the state's Division of Gaming Enforcement, filed a petition for a writ of certiorari — the procedural vehicle a losing party uses to bring a dispute before the nation's highest court — in New Jersey's enforcement action against Kalshi over sporting event contracts. The court filing cites parallel civil cases brought by gaming authorities in at least 20 states and asks the justices to resolve whether a prediction market company can be in compliance with the Commodity Futures Trading Commission (CFTC) while violating state law. At the center of the dispute is a preemption question: whether the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act bars states from regulating sports bets placed within their borders when those bets are offered on CFTC-registered markets. “Companies like Kalshi claim to offer legal sports betting in all 50 States, but they refuse to follow the gambling laws of any State,” Davenport said in announcing the petition, arguing that Congress never silently made the sports-betting industry immune from state law. The filing challenges an April decision from the US Court of Appeals for the Third Circuit, where judges ruled 2-1 against New Jersey's gaming authorities and found Kalshi had a reasonable chance of success in arguing that the Commodity Exchange Act preempts state law. It also pushes back on the CFTC's position that sports bets on prediction platforms amount to “swaps” under federal oversight. Kalshi spokesperson Dani Lever responded that the company remains confident in the lower courts' rulings and cannot be “regulated by 50 different regulators.”

Kalshi Suspends Candidate Over Her Own Race

Separately, Kalshi moved against one of its own users in a case that shows how seriously the platform polices conflicts of interest. Republican House candidate Laurie Buckhout has been suspended from trading for three years after placing bets on her own election, according to the Washington Post, which first reported the settlement. After declaring her candidacy in December for North Carolina's 1st Congressional District, Buckhout bought less than $1,000 worth of contracts tied to her contest against incumbent Democratic Representative Don Davis. Kalshi determined that, as a candidate, she qualified as a “direct decision-maker” with direct influence over the outcome — the platform's threshold for insider trading — and a settlement that took effect last Friday bars her from betting for three years and imposes a $2,589.96 penalty. Buckhout, a retired Army colonel who lost to Davis in 2024 and has recently served in the Trump administration's War Department as a cyber policy official, acknowledged the lapse. “It was a stupid mistake, and as soon as I recognized there was an issue, I tried to correct it,” she said, adding that her career as a Kalshi trader was “fairly short-lived.” The episode lands at a delicate moment for the sector. Prediction platforms sit at the intersection of finance, gaming and crypto-adjacent speculation — a user base that overlaps with tokenized sports and fan-engagement projects such as Chiliz (CHZ) — and enforcement attention is intensifying on both the state and federal levels. For Kalshi, suspending a candidate over bets worth under $1,000 reads as a deliberate self-regulatory signal: the platform polices insider activity on its own books even as it fights states over who holds the right to supervise it at all.

Preemption Question Now Before the Justices

Taken together, the two developments sketch a sector maturing faster than its regulatory perimeter can hold. The document now before the Supreme Court is explicit: the petition asks whether Dodd-Frank preempts state regulation of sports bets on CFTC-registered markets, and it contests the agency's treatment of those contracts as “swaps,” stating that “federal law does not preempt state sports-gambling laws regardless.” Our reading: the answer will define the boundary for every CFTC-registered venue listing event contracts — including those tied to Bitcoin (BTC) price levels — and for decentralized rivals settled on networks such as TRON (TRX). Unlike token niches such as Regenerative Finance (ReFi), whose fortunes ride on market cycles, prediction markets' fate now turns on jurisdiction — and retail-scale event speculation of the kind that once surrounded GameStop (GME) sits squarely inside that contested line.
