Kalshi

In 2018, Kalshi was established by Tarek Mansour and Luana Lopes Lara, two financial analysts. Initially, the project was briefly known as "Kownig". In November 2020, Kalshi attained a license from the Commodities Futures Trading Commission (CFTC), registering the platform as a designated contract market. The site was publicly launched in July 2021. Beginning in 2022, Kalshi's attempts to offer political and election-related betting faced sustained legal and regulatory challenges from the CFTC. The CFTC delayed decisions on these contracts, questioning whether they constituted valid risk-hedging tools and if they served the public interest. Internal disagreement emerged, with Commissioner Caroline Pham dissenting and arguing the contracts were not prohibited and did not require a public-interest test. In 2023, another months-long legal dispute began between Kalshi and the CFTC. Kalshi repeated that its contracts serve the public interest. In contrast, the CFTC contends that these contracts constitute illegal gambling and that it lacks the resources to oversee them effectively. Chairman Rostin Behnam has cautioned that allowing election contracts could "ultimately commoditize and degrade the integrity" of the electoral process. Despite revised proposals allowing very large bets by hedge funds and institutions, the CFTC ultimately rejected Kalshi's congressional control contracts in September 2023. Kalshi responded by suing the agency, claiming it exceeded its authority. After a 2024 ruling by the DC District Court, CFTC had overstepped by blocking the contracts, and an appellate court later rejected the CFTC's request for a stay, Kalshi was allowed to relaunch its congressional control betting operations. In 2025, Kalshi became the infrastructure for Robinhood's event contracts Prediction Markets Hub. In 2025, Kalshi signed formal partnerships with media outlets CNN and CNBC, possibly bringing betting odds into NFL television broadcasts, as is already common for data from traditional sportsbooks. A volume of $3–5 billion was bet on NFL games, with Barron's saying that "Kalshi [...] Need[s] the NFL. As of March 2026, the company is valued at $22 Billion. == Controversies ==

Efforts to make the site accessible for younger audiences In 2025, Kalshi engaged in efforts to create a "student ambassadors" program where students could sign up to promote Kalshi on their campuses, in order to "[bring] the next 100M users to prediction markets." Following the backlash, the related social media post and webpage were taken down. Betting on Gaza war The site has been heavily criticized for including and thus capitalizing on humanitarian issues, such as whether the Palestinian population would be suffering from a food shortage due to the Gaza war. Opposition to Kalshi's election betting While Kalshi argues that betting on political event would improve oversight to political and economic developments while also providing accurate forecasting data (which has been challenged by scholars), critics such as Consumer advocacy groups like Better Markets contend that election betting could undermine election integrity and public trust by turning elections into speculative trading vehicles. Holding back payouts of won NFL bets In January 2026, users who held correct positions on certain NFL bets were only repaid their original stake, rather than the full winnings. Only following backlash by many users and gambling industry analyst Dustin Gouker, Kalshi reacted and paid out the users. AI-generated ads During the NBA finals, Kalshi aired an ad that was created using generative AI models, such as Google's Veo 3 and OpenAI's ChatGPT. Reactions to the ad that was created by a self-proclaimed "AI filmmaker" were decidedly mixed, with Business Insider deeming it "chaotic". Insider trading In February 2026, a video editor for YouTuber MrBeast was fined and suspended from Kalshi for suspected insider trading. In April 2026, Kalshi fined and suspended three congressional candidates for betting on their own political races, including Matt Klein, a Democrat State senator in Minnesota. Khamenei death A market for the ousting of the Supreme Leader of Iran was hosted on the site. Upon Ali Khamenei's death, Kalshi froze the trade, citing it does not allow transactions "directly tied to death". A total of $77 million in winnings for people who had bet that Khamenei would be out of office by 1 March 2026 were not paid out. == Legal issues ==

Massachusetts In September 2025, Massachusetts Attorney General Andrea Campbell filed a lawsuit that accused Kalshi of "promoting and accepting sports wagers" without following Massachusetts gambling laws, as the practice is banned there. In January 2026, a Massachusetts Superior Court judge issued a preliminary injunction against Kalshi, effectively banning the platform from offering sports-based betting within the state. Under the court order, Kalshi was required to implement geofencing technology to block Massachusetts residents from accessing sports-related markets on its platform. New York In November 2025, a proposed class action lawsuit was filed against Kalshi in New York state, alleging that Kalshi "engaged in illegal deceptive activity, and unjustly enriched itself at the expense of tens of thousands of consumers" by operating unlicensed sports betting as well as leading users to unknowingly bet against Kalshi or its partners rather than against other users. Kalshi co-founder Luana Lopes Lara called the lawsuit "baseless". Ohio On March 9, 2026, Ohio federal judge Sarah D. Morrison ruled that Kalshi's products amounted to gambling in the state of Ohio and should come under the jurisdiction of the Ohio Casino Control Commission rather than the CFTC. Morrison's opinion expressed she wanted to "avoid absurdity". Ohio Attorney General Dave Yost celebrated the ruling, commenting on X that the ruling was a "big win" for the state. Kalshi, in its response, pledged to appeal, citing a positive injunctive ruling coming from Tennessee. Arizona In March of 2026, Arizona Attorney General Kris Mayes and state prosecutors filed criminal charges against Kalshi, alleging that it was running an illegal gambling business and election wagering. The release noted that Arizonans were able to bet on professional and sporting events, individual player performance, and political issues, like whether the SAVE Act would become law. The 20 charges were all misdemeanors, punishable by fines up to $20,000. Kalshi said in a statement that the charges were "meritless" and they were looking forward to fighting the charges in court. Nevada In March of 2026, a temporary ban on Kalshi was enacted in the state of Nevada. On 20 March 2026, the first Judicial District Court of Nevada issued a 14-day restraining order, barring the company from "offering a derivatives exchange and prediction market which offers event-based contracts relating to sports, election, and entertainment related events" without having first obtained gambling licenses. Washington On March 27, 2026 the state of Washington filed a lawsuit against Kalshi, alleging that the company has been operating in violation of state laws concerning illegal gambling. On the same day Kalshi filed a notice of removal to federal court, arguing that the charges concern federally regulated derivatives. Native Reservations In July 2025, three Californian tribesthe Blue Lake Rancheria, Chicken Ranch Rancheria of Me-Wuk Indians and Picayune Rancheria of Chukchansi Indiansfiled a federal lawsuit against Kalshi, alleging that it is conducting illegal sports gambling on tribal lands in violation of federal gaming laws. They argue that Kalshi’s sports event contracts constitute Class III gaming under the Indian Gaming Regulatory Act and thus violate their exclusive right to regulate gaming on reservation lands. In September of the same year the Ho-Chunk Nation of Wisconsin filed a similar lawsuit. Michigan In March 2026, Michigan Attorney General Dana Nessel in collaboration with the Michigan Gaming Control Board filed a lawsuit against Kalshi. They allege that the platform conducts illegal sports betting, as Kalshi's operations in Michigan circumvent the state's Lawful Sports Betting Act, requiring such platforms to be licensed through the Michigan Gaming Control Board. In a press statement, Nessel said that "Corporations cannot circumvent state gaming laws." and that her office is working towards "[...] ensur[ing] that betting in [Michigan] remains lawful, fair and subject to the oversight of [its] residents expect and deserve.” == See also ==
