History
Founded in 2018, Kalshi was established by Tarek Mansour and Luana Lopes Lara.
The idea for the company emerged during their tenure as
financial analysts, where they identified challenges faced by investors attempting to
hedge

their investments amidst uncertainties such as the
Brexit referendum. The founders note that the absence of a direct safeguard against unfavorable outcomes was what prompted them to envision a platform that would allow investors to engage in wagers on future events, providing a means to hedge uncertainties and capitalize on insights.
After attempting for 18 months, Mansour and Lara obtained a federal license from the
Commodities Futures Trading Commission (CFTC) on November 3, 2020,
registering as a designated contract market. Kalshi's case was strengthened by the presence of several prediction markets that operated without seeking regulatory approval, such as

As of April 2023, the bet limit allowed on the platform is $25,000,

Kalshi charges transaction fees per trade but does not rely on traders' losses for its revenue.

Axios'' noted as marking a significant milestone in the platform’s efforts to provide consistent liquidity. In March 2025,
Robinhood launched prediction markets hub powered by Kalshi, offering contracts on sports and policy outcomes.
Election contracts
On October 2, 2024, a
federal appeals court in
Washington D.C. allowed Kalshi to revive the first fully regulated election markets in the U.S. by lifting a temporary freeze on trading. The three-judge panel rejected Wall Street regulators' emergency request to halt the markets during an appeal process. Judge Patricia Millett highlighted the CFTC's failure to prove that these contracts threatened election integrity, and ''Politico'' described the ruling as a "major win for the burgeoning political betting complex in the U.S." It enabled Kalshi to offer trades on which party would control Congress, with plans to expand into other political contests, including the presidential election. Kalshi CEO Tarek Mansour described it as a "new era for financial markets." Fully regulated by the CFTC, Kalshi allows wagers of up to $100 million on election markets, unlike offshore markets and academic ventures, which previously restricted American traders to small wagers of a few hundred dollars.
On October 3, Kalshi introduced a contract on the presidential election winner, providing a mechanism for
hedging potential losses. Following the favorable ruling, the platform listed over two dozen new options related to political outcomes, including the
presidential race,

Mansour has emphasized that these contracts serve as a tool for investors to hedge against financial impacts from various political outcomes, rather than trying to influence elections, and that they capture risks such as the potential effects of presidential tariffs on financial situations. He has also noted that Kalshi's political outcome contracts offer a more direct hedging approach compared to traditional investment bank "bundles" that hedge against the election of specific candidates and has highlighted a diverse customer base that includes both risk hedgers and speculators.

Kalshi faces challenges in dealing with questions that have continuous answers and providing clear results to a large user base.
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.
Election markets proposals
Kalshi has faced regulatory challenges in its efforts to create markets regarding political control of Congress. The company has sought approval from the CFTC to introduce election contracts resembling
options or futures. These contracts are "cash-settled, binary contracts" based on questions such as which political party will control a specific chamber of Congress.
2022
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.
2023
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.
In June 2023, Kalshi proposed a new plan that would allow hedge funds and other major

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. 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.
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. 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.
2024
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.
The CFTC quickly appealed the judge's decision to the

, requesting an emergency stay.
They argued that the contracts were illegal and could potentially undermine election integrity.
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.
On October 2, 2024, a U.S. 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.
Judge
Patricia Millett indicated that the CFTC could renew its request for a stay if new evidence emerges during the appeal process. ''
