Kalshi's legal history is central to understanding how prediction markets operate in the United States. From its landmark CFTC approval to courtroom battles over election contracts, Kalshi has been at the forefront of defining the legal framework for event trading. This guide covers the major lawsuits, regulatory milestones, and state-by-state legality questions that traders need to understand.
The CFTC approval story
Kalshi's legal journey began with its application to the Commodity Futures Trading Commission (CFTC) for designation as a Designated Contract Market (DCM). In 2020, Kalshi became the first exchange to receive CFTC approval specifically for event contracts.
This approval was groundbreaking because it established that binary contracts on real-world events could be legally traded by US retail investors on a regulated exchange. Prior to Kalshi's approval, prediction markets in the US were limited to academic platforms with strict caps (like PredictIt's CFTC no-action letter) or offshore platforms operating outside US jurisdiction.

The election contract lawsuit
The most significant legal battle in Kalshi's history centered on election event contracts. When Kalshi sought to list contracts on US congressional elections, the CFTC initially blocked the effort, arguing that election contracts constituted "gaming" and were contrary to the public interest.
Kalshi sued the CFTC in federal court, challenging the agency's interpretation. This case raised fundamental questions about what types of events can be traded on regulated exchanges:
- Kalshi's argument: Election contracts are legitimate financial instruments that provide valuable price discovery and risk management. They are not gambling because the outcomes affect real economic and policy decisions.
- CFTC's argument: Election contracts are effectively political betting and fall outside the scope of legitimate futures trading. Allowing them could undermine election integrity.
- Court ruling: The federal court ruled in Kalshi's favor, finding that the CFTC had exceeded its authority in blocking election contracts. This ruling was a watershed moment for the prediction market industry.
- Appeals: The legal process involved multiple stages, including appeals and temporary stays, before Kalshi was able to list election contracts.
The election contract lawsuit established important legal precedent for the entire prediction market industry, not just Kalshi.
State-by-state legality
While Kalshi is federally regulated by the CFTC, individual states also have authority over whether their residents can access the platform. This creates a patchwork of availability across the US. For detailed state-level information, see our Kalshi state restrictions guide.
Here is a summary of how state legality works:
States where Kalshi is available: The majority of US states allow Kalshi trading. Residents of these states can create accounts, deposit funds, and trade all available markets.
Restricted states: Some states have laws or regulatory interpretations that prevent Kalshi from offering services to their residents. These restrictions may apply to all prediction market contracts or only to specific categories (like election contracts).
Common questions by state:
- California: California has historically been one of the more restrictive states for prediction market trading. Kalshi's availability in California depends on the current regulatory environment and any agreements between Kalshi and California regulators.
- Texas: Texas has generally been more permissive toward financial trading platforms. Kalshi has operated in Texas, but traders should verify current availability on the platform.
- Washington state: Washington has complex gambling and trading regulations. The state's laws have created uncertainty about prediction market legality, and Kalshi's availability has varied.
State-level legality can change as regulations evolve and as Kalshi negotiates with individual state regulators. Always check the Kalshi website for current availability in your state.
The regulatory framework
Kalshi operates under a specific regulatory framework that distinguishes it from gambling and traditional financial markets:
- DCM designation: As a Designated Contract Market, Kalshi is subject to CFTC oversight, including capital requirements, customer protection rules, and market surveillance.
- Segregated funds: Kalshi is required to keep customer funds segregated from company funds, providing protection in the event of financial difficulties.
- KYC/AML compliance: All users must complete identity verification, and Kalshi monitors for suspicious trading activity.
- Position limits: The CFTC may impose position limits on certain contracts to prevent market manipulation.
- Market surveillance: Kalshi conducts ongoing market surveillance to detect and prevent manipulation, wash trading, and other prohibited activities.
This regulatory framework is what makes Kalshi different from offshore prediction markets. For a comparison with less-regulated alternatives, see our Kalshi vs. Polymarket analysis.
Ongoing legal considerations
The legal landscape for prediction markets continues to evolve:
Congressional interest: Multiple bills have been introduced in Congress that could affect prediction market regulation, ranging from expanding access to imposing new restrictions.
State-level developments: Individual states continue to evaluate their approach to prediction markets. Some are moving toward explicitly permitting them, while others are considering restrictions.
CFTC rulemaking: The CFTC periodically issues new rules and guidance that affect how prediction markets operate. Proposed rules go through public comment periods where industry participants and traders can provide input.
Sports and entertainment markets: The legal status of specific market categories, particularly sports-adjacent contracts, remains an active area of regulatory discussion. See our article on Kalshi sports betting for more context.
What this means for traders
For active Kalshi traders, the legal landscape has several practical implications:
- Platform stability: Kalshi's CFTC regulation provides strong legal protection. The platform is unlikely to be shut down absent extraordinary circumstances.
- Contract availability: Legal battles may temporarily affect which contracts are available. Election contracts, for example, were unavailable during part of the litigation.
- Tax obligations: Kalshi's regulated status means your trading activity is reported to the IRS. Understand your tax obligations. See our Kalshi taxes guide.
- State moves: If you move to a restricted state, you may lose access to your Kalshi account. Factor this into your planning if relocation is possible.
Kalshi's legal history is a story of expanding access to prediction markets in the United States. While challenges remain, the trajectory has been toward greater availability and clearer regulation, which benefits traders and the broader market ecosystem.
