Kalshi Faces Citadel and Cboe Lawsuit Over Perpetual Futures
United States.- 10 November 2026 | www.zonadeazar.com Kalshi has become the focus of a new Wall Street regulatory dispute after receiving approval to offer perpetual futures contracts linked to individual stocks.
The authorisation granted by the US Commodity Futures Trading Commission (CFTC) prompted a lawsuit brought by an industry association backed by Citadel Securities and Cboe Global Markets.
The dispute highlights growing competition between established financial institutions and platforms introducing derivatives originally popularised in cryptocurrency markets.
Kalshi Launches Contracts Linked to Over 50 Stocks
The platform received regulatory approval to introduce perpetual futures linked to more than 50 individual securities.
The underlying assets include companies such as:
- Meta, owner of Facebook and Instagram.
- McDonald’s, the international restaurant group.
- SpaceX, the aerospace company.
The contracts allow traders to gain exposure to price movements without purchasing the underlying shares.
Tarek Mansour, CEO of Kalshi, said the launch became the company’s most successful product introduction within its first 24 hours.
What Are Perpetual Futures?
Perpetual futures, commonly known as perps, are derivatives designed to track the price of an underlying asset.
Unlike conventional futures, they do not have a fixed expiry date.
Their main characteristics include:
- Exposure to price movements without ownership of the underlying asset.
- No mandatory contract expiry date.
- The possibility of leveraged trading.
- Potentially amplified gains and losses.
- Continuous trading, depending on the platform’s arrangements.
These instruments gained popularity within cryptocurrency markets and are now expanding into other financial assets.
Citadel and Cboe Challenge Regulatory Approval
An industry association supported by Citadel Securities and Cboe has filed a lawsuit against the CFTC seeking to halt trading in the new contracts.
The claimants argue that perpetual futures linked to individual stocks should legally be classified as security-based swaps.
Under that interpretation, the contracts would fall within the regulatory framework overseen by the US Securities and Exchange Commission (SEC).
The legal dispute therefore concerns which authority has jurisdiction over these financial products.
SEC Rules Could Restrict Retail Access
If the contracts are classified as security-based swaps, they would become subject to a different regulatory framework.
The relevant rules restrict certain transactions to institutional participants and impose additional investor protection requirements.
Consequently, the classification sought by the claimants could significantly limit access for retail traders.
Citadel and Cboe argue that permitting the contracts under the CFTC framework could weaken safeguards established for securities markets.
Kalshi Says Lawsuit Threatens Competition
Kalshi has rejected the allegations, arguing that the legal challenge is intended to restrict competition from emerging trading platforms.
From the company’s perspective, perpetual futures offer an alternative to certain financial instruments available through traditional exchanges.
The dispute also has commercial implications for derivatives exchanges and market-making firms.
A shift towards perpetual futures could change trading volumes across established markets.
Federal Judge Raises Questions Over Approval
US District Judge Valerie Caproni has introduced an expedited timetable to consider whether trading in the contracts should be temporarily suspended.
During preliminary proceedings, she indicated that the claimants’ legal arguments appeared likely to succeed on their merits.
However, no final ruling has determined the legal classification of the products.
The court’s decision will be important in establishing whether Kalshi can continue offering the contracts while litigation proceeds.
CME and Intercontinental Exchange Join Wider Debate
The dispute comes amid growing interest in perpetual futures across financial markets.
CME Group previously filed a lawsuit against the CFTC concerning the approval of cryptocurrency perpetual contracts.
Meanwhile, Intercontinental Exchange (ICE), owner of the New York Stock Exchange, has announced plans to introduce Hyperliquid-based perpetual products in the United States, subject to regulatory approval.
These developments demonstrate that the debate involves different strategies among both established financial institutions and emerging trading platforms.
Industry Impact and Next Steps
The outcome could establish an important precedent for prediction markets, cryptocurrency-related platforms and financial derivatives providers.
The central question is whether these instruments should be regulated as futures under CFTC supervision or as securities-related products subject to SEC requirements.
With contracts linked to more than 50 stocks and a lawsuit backed by Citadel Securities and Cboe, Kalshi is at the centre of a dispute that could reshape the boundaries between traditional financial markets and emerging trading platforms.
The next development will be the court’s decision on the request to temporarily suspend trading.
