Kalshi Inc. is an American web-based prediction betting platform launched in July 2021, that offers a platform for users to place bets on future events, including economic indicators, sports and cultural events and political outcomes. More than 90% of the activity on the site is sports gambling. [1]
The site has been involved in controversies and lawsuits. In 2025, the site entered into a partnership with CNN and CNBC; the news outlets said the gambling on Kalshi provided useful indicators of public sentiment in real time. [2] Scholars have challenged that Kalshi efficiently and accurately aggregates information about outcomes. [3]
In 2018, Kalshi was established by Tarek Mansour and Luana Lopes Lara, [4] two financial analysts. Initially, the project was called "Kownig", however that was changed for marketing reasons. The current name translates to "everything" in Arabic. [5]
In November 2020, the website attained a license from the Commodities Futures Trading Commission registering the casino as a designated contract market. [6] [7] [8] In July 2021, the site was publicly launched. [9]
In April 2024, Susquehanna International Group became Kalshi's first dedicated institutional market maker. [10] In March 2025, Robinhood launched a betting markets hub powered by Kalshi. [11]
In January 2025, controversial public figure Donald Trump Jr. announced that he would be joining Kalshi as a strategic adviser. [12]
The company was valued at $2 billion in June 2025. [13] Later that year, Kalshi announced worldwide expansion of its operations, following a $300 million Series D funding, that values the company at $5 billion. [14]
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 backlash, the related social media post and webpage have been taken down. [15] [16]
Kalshi allows traders to place bets on various issues spanning topics like climate change, economic indicator, events in music and film as well as presidential approval ratings and the passing of significant cases in Congress and Supreme Court in the form of a yes/no question. [5] [17] [18] [19] [20] [21] [22] [23]
During the 2024 presidential race, the casino hosted bets on popular vote, Electoral College margins, swing state results and individual Senate contests, totaling in a volume of $3 million dollars bet. [24]
Although Kalshi lacks formal standing with the Securities and Exchange Commission (SEC), its current offerings are limited enough that it is expected to operate under the regulations of the Commodity Futures Trading Commission (CFTC) alone. Matthew Kluchenek, a partner at Mayer Brown, stated that the SEC may intervene if the contract market is perceived to have an impact on securities prices in other markets. [25] Kalshi has engaged in talks with brokerage firms to include its platform in their listings and with other investment firms to act as market makers on the exchange. Orders on Kalshi remain on the books until a second trader is willing to take the opposing side of the contract, potentially resulting in lower volumes and liquidity. The company has an affiliate called Kalshi Trading, which trades and provides liquidity for many of its contracts. [25]
The company aims to attract larger investors who may leverage it for hedging purposes and capitalize on opportunities presented by less-informed participants. However, broader adoption faces hurdles, such as the zero-sum nature of prediction markets and the need for increased liquidity to entice larger investors. [26]
Kalshi's application faced delays as the CFTC closely examined whether Kalshi's contracts could effectively serve as hedges. Commissioner Caroline Pham, one of the CFTC's top two Republican officials, dissented on the decision to review Kalshi's political event contracts in August 2022. She argued that the underlying activity of the contracts, which involves political control, is not prohibited and that the agency had not established a clear test for what goes against the public interest, eliminating the need for a public interest test. In October 2022, the commission staff recommended against Kalshi's proposal to introduce higher-stakes futures contracts related to the control of Congress resulting from the midterm elections, and the CFTC delayed a decision on Kalshi's application. [27]
In 2023, a monthslong legal dispute began between the Kalshi and the CFTC over political event contracts. The company maintains that its contracts serve the public interest by offering accurate election forecasting data and enabling individuals to hedge against various outcomes. 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. [28]
In June 2023, Kalshi proposed a new plan that would allow hedge funds and other major Wall Street firms to wager up to $100 million on which US political party would control Congress. Under the plan, all users could wager up to $250,000, but large trading firms could trade $50 million on the outcome of the next congressional elections, with those demonstrating an economic hedging need allowed to bet even more. [29] The CTFC opted to request a second round of public comment on Kalshi's plans. The two Republican commissioners, who were in the minority on the CFTC's board, dissented against the prolonged process, arguing that the question of whether Kalshi's products constitute prohibited "gaming" should be addressed directly through a clear rule. [30]
In September 2023, the CFTC rejected Kalshi's proposal to offer derivatives contracts on congressional control, which it deemed contrary to the public interest, citing concerns that the planned contracts would violate derivatives market regulations. The decision prohibited the listing, clearing, or trading of Kalshi's political event contracts. [31] In November, Kalshi filed a lawsuit against the CFTC over their denial of the company's bid, alleging that it had exceeded its authority in blocking their proposal. [32]
On September 12, 2024, DC District Court Judge Jia Cobb rejected the CFTC's attempt to delay the company's congressional control contracts, ruling in favor of Kalshi. Cobb stated that the agency had exceeded its authority by blocking these contracts, emphasizing that Kalshi's offerings do not constitute illegal activity or gaming, as they pertain to elections. [28] The CFTC quickly appealed the judge's decision to the DC Circuit Court of Appeals, requesting an emergency stay. [33] They argued that the contracts were illegal and could potentially undermine election integrity. [28] Kalshi launched its election wagers just hours before the appellate ruling. The company warned that pausing Cobb's ruling would severely impact its operations, describing the CFTC's request as a tactic to stall their progress, while also noting the rise of the unregulated prediction market Polymarket following a recent presidential debate. [28] On October 2, 2024, a US federal appeals court denied the CFTC's request and upheld the lower court's decision, allowing Kalshi to offer political event contracts. The D.C. Circuit Court determined that the CFTC failed to demonstrate any potential harm to the public interest from Kalshi's event contracts. This ruling enabled Kalshi to offer trading ahead of the November 5 elections and may set a precedent for other firms looking to enter the prediction market space. [33] Judge Patricia Millett indicated that the CFTC could renew its request for a stay if new evidence emerges during the appeal process. [34] Politico described the ruling as a "major win for the burgeoning political betting complex in the U.S.," enabling Kalshi to offer trades on which party would control Congress, with plans to expand into other political contests, including the presidential election. [35]
In July 2025, Kalshi launched prediction markets for trading on the probability of tech companies going public via IPOs by year-end. These markets reflected investor sentiment through contract prices, focusing on companies like Databricks (21%), OpenAI (5%), Klarna (72%), Stripe (6%), Brex (9%), and xAI (4%).
Kalshi relaunched its congressional control contracts on the same day, [36] allowing Americans to wager on which party will control the House and Senate in 2025. These contracts were initially introduced on September 12 after the US District Court judge rejected the CFTC's attempt to block them, but the CFTC's rapid appeal temporarily halted the offerings. [28]
In December 2025, Kalshi signed a deals with news companies CNN and CNBC to become a official prediction markets partner of this two companies. [37] [38]
Kalshi claims that bringing political trading to their platform would improve oversight and accessibility, transforming a historically underground practice into a regulated financial option for retail participants. CEO Tarek Mansour has stated their platform is another form of risk management through hedging against significant economic or political changes. [39] They have argued that political event contracts not only serve the public interest by delivering accurate forecasting data but also empower users to manage financial uncertainties tied to evolving political landscapes, and have highlighted the significant activity in unregulated markets like Polymarket, which has seen over $1 billion in wagers on presidential races. [28]
Kalshi's proposals have been backed by wealthy owners and executives in commodities trading, including Vivek Ranadivé, co-owner of the Sacramento Kings, Jason Furman, a former White House economist, Intercontinental Exchange, which operates the New York Stock Exchange, as well as several former CFTC officials. [40] [41] Some market participants, including Angelo Lisboa, managing director of JPMorgan's private wealth management division, have expressed their support for Kalshi's proposals, recognizing election risk as a significant concern for their clients and noting the potential impact of bringing such capabilities to a broader population that lacks access to large banks' resources. [42]
Critics of election betting contracts argue that the contracts could threaten election integrity. [33] Consumer advocacy groups, such as D.C.-based Better Markets, express fears that such trading could turn elections into a new vehicle for day trading and further erode public trust in election results. In August 2023, in a letter to the CTFC, senators Jeff Merkley, Sheldon Whitehouse, Ed Markey, Elizabeth Warren, Chris Van Hollen and Dianne Feinstein urged the CFTC to reject Kalshi's proposal, raising concerns over electoral integrity. [43] Stephen Hall of Better Markets labeled the ruling "a sad and ominous day for election integrity" in the US following the October 2024 ruling allowing Kalshi to list contracts on election outcomes. [28]
In September 2025, Massachusetts Attorney General Andrea Campbell filed a lawsuit which accused Kalshi of "promoting and accepting sports wagers" without following Massachusetts gambling laws, as the practice is banned there. [44]
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." [45]
