Spain joined a growing list of national authorities restricting or banning prediction market platforms amid concerns over unlicensed gambling activities. Spain’s gambling regulator blocked local users from Polymarket and Kalshi “as a precautionary measure” as authorities there address allegations the prediction markets platforms were in violation of gambling laws. On Tuesday, Spain’s Directorate General for the Regulation of Gambling (DGOJ) said the country’s Ministry of Social Rights, Consumption, and Agenda 2030 had opened legal proceedings against the two companies, as they appeared to be operating without necessary licensing. The DGOJ issued an order blocking Spanish users from Kalshi and Polymarket until the proceedings were resolved, expected in three to four months. “The DGOJ wishes to remind the public that, in Spain — in line with other European jurisdictions — prediction markets are deemed to constitute games of chance when bets are placed on uncertain future outcomes,” according to a Tuesday notic...
"We’re not going to be outspent or out-organized by entrenched interests protecting their monopolies," said John Bivona, head of government relations at Kalshi. Kalshi has backed a new lobbying group for prediction markets called Americans for Fair Markets, which has tapped former deputy White House chief of staff Taylor Budowich as its strategic advisor. Kalshi said on Friday that the organization is positioning itself against sportsbooks and casinos, which it claims are “focused on protecting their monopolies and seeding lies about prediction markets to policymakers.” Americans for Fair Markets, which Kalshi said was launched with its support, would join a broader lobbying push that includes the Coalition for Prediction Markets, an advocacy group for prediction markets launched in December 2025, backed by Coinbase, Crypto.com, and Robinhood.

The Commodity Futures Trading Commission has urged the Sixth Circuit Court of Appeals to rule that the agency has jurisdiction over prediction markets.

The CFTC filed an amicus brief in the Sixth Circuit Court of Appeals on Tuesday, accusing Ohio of “jurisdictional overreach” after state authorities told Kalshi last year to stop offering sports event contracts in the state, calling them unlicensed sports gambling. Kalshi sued Ohio authorities in October, seeking to have a federal court stop the Ohio Casino Control Commission and the state attorney general from taking action, but the court denied the request in March, leading Kalshi to appeal the decision.

Brazil has blocked 27 prediction market platforms, including Kalshi and Polymarket, as new rules classify many contracts as gambling. Brazilian authorities have moved to shut down 27 prediction market platforms, including Kalshi and Polymarket. The decision, announced Friday, follows a directive from the Ministry of Finance and enforcement by the National Telecommunications Agency (Anatel), according to state-owned news outlet Agência Brasil. Authorities claimed that such services fall outside Brazil’s current legal framework and therefore operate illegally. “We have been monitoring the evolution of this sector in Brazil, which suffered a period of anarchy because there were no rules, no oversight, from 2018 to 2022,” Finance Ministry executive secretary Dario Durigan reportedly said during a press conference at the Palácio do Planalto.

Wisconsin’s lawsuit against Kalshi, Robinhood, Coinbase, Polymarket and Crypto.com deepens the battle between state gambling enforcers and federal regulators over sports prediction markets.

Oracle network Pyth Network has been selected as the resolution data source for Kalshi’s expansion into commodities markets, underscoring the growing focus on reliable pricing infrastructure in event-based trading. Kalshi said on Wednesday that Pyth will supply real-time pricing data for its newly launched commodities hub, which debuted in April. The data will be used to determine how event contracts tied to commodity prices are settled. The move reflects a broader push among prediction market platforms to strengthen backend infrastructure as they expand into more complex asset classes. Accurate, tamper-resistant data feeds are critical for ensuring fair and transparent contract resolution, particularly in markets tied to real-world financial benchmarks. Read more

CEO Tarek Mansour said in an interview that Kalshi would prevent kids from using a parent’s ID to skirt its age restrictions by launching a parent portal and AI verification. Kalshi co-founder and CEO Tarek Mansour reportedly announced a new strategy for the prediction markets platform to crack down on minors illegally using its services. According to a Wednesday Semafor report, Mansour said that Kalshi was launching a “portal for parents” to submit their identification to check whether their children were using the platforms under their names. There have been incidents in which minors have been able to bypass Kalshi’s age requirements — a US-based user must be 18 years old — by using one of their parent’s IDs for verification. “We are also adding selfies to accounts, where you can basically look at the face of a person, and it can tell you obviously if this person is not the actual parent that’s 50 years old,” said Mansour, according to Semafor.

A federal judge in Arizona has temporarily barred state officials from enforcing gambling laws against Kalshi, siding with the CFTC. A federal judge in Arizona has temporarily barred state officials from enforcing gambling laws against Kalshi, siding with US regulators in a growing dispute over how event-based trading products should be classified. In an order issued on Friday, Judge Michael Liburdi of the US District Court for the District of Arizona granted a request from the Commodity Futures Trading Commission (CFTC) and the federal government to halt any state-level action targeting contracts listed on CFTC-regulated markets . The ruling centers on whether Kalshi’s “event contracts” fall under federal derivatives law or state gambling statutes. Last month, Arizona authorities sought to pursue enforcement against Kalshi under local gambling rules, but the CFTC asked a court order on Wednesday to stop the action. Read more
The US Justice Department and commodities regulator asked a federal court to block Arizona’s action against Kalshi, arguing federally regulated event contracts fall under CFTC jurisdiction. The US Department of Justice (DOJ) and Commodities and Futures Trading Commission (CFTC) asked a federal court to block Arizona from enforcing state gambling law against Kalshi’s event contracts, arguing that they fall under the CFTC’s exclusive authority over swaps markets. The Wednesday filing argues that event contracts listed on federally regulated platforms such as Kalshi are swaps under the Commodity Exchange Act and therefore fall within the CFTC’s exclusive jurisdiction. The filing says Arizona’s enforcement effort unlawfully intrudes on the CFTC’s exclusive jurisdiction over federally regulated event-contract markets. Read more
As states seek to regulate prediction markets, a panel of federal judges ruled in favor of Kalshi’s position that only the CFTC has jurisdiction. A US appellate court has ruled against New Jersey gaming authorities for bringing an enforcement action against prediction market platform Kalshi over sports event contracts. In a Monday-issued opinion, a panel of judges in the US Court of Appeals for the Third Circuit ruled 2-1 in favor of Kalshi’s argument that the company had a ”reasonable chance of success” claiming that the Commodity Exchange Act preempted state law, setting the stage for a potential battle over gaming laws in the US Supreme Court. "This is a big win for the industry and millions of users," Kalshi CEO Tarek Mansour said in a social media post on X. Read more
The judge said Kalshi’s event contracts are indistinguishable from sports betting, supporting the state’s position that the platform requires a gaming license. A Nevada judge has reportedly extended a ban preventing Kalshi from offering event-based contracts in the state, ruling that the products constitute unlicensed gambling under state law. Judge Jason Woodbury said at a hearing in Carson City on Friday that he will grant a preliminary injunction requested by the Nevada Gaming Control Board, barring the company from allowing residents to trade on outcomes such as sports, elections and entertainment events without a gaming license, according to Reuters. The decision extends a temporary restraining order issued on March 20, which will remain in effect through April 17 while the court finalizes longer-term restrictions. Read more
