Cboe and Citadel sue CFTC to block US stock perps

Cboe and Citadel Suing to Block Stock Perps: What Is the Lawsuit About?

The Capital Markets Alliance, which includes Cboe, Citadel Securities and the Healthy Markets Association, filed in federal court in Manhattan, arguing single-stock perpetuals are security-based swaps under SEC jurisdiction and should be restricted from retail access. The group asks the court to:

• Vacate the CFTC’s approval issued under Regulation 40.3
• Declare the contracts security-based swaps
• Freeze trading while the case proceeds

Cboe CEO Craig Donohue stated the issue concerns investor protection in securities trading and adherence to law. The CFTC responded that markets should be governed by law rather than litigation campaigns that block innovation.

Four exchanges await clarity: Kalshi filed on September 18, followed by Coinbase Derivatives, Bitnomial and Crypto.com’s North American Derivatives Exchange. CME Group is separately suing the CFTC over Kalshi’s Bitcoin perpetual approved in May.

How Big Are Stock Perps on Hyperliquid?

Stock and index perps are significant relative to Hyperliquid’s crypto markets. Hyperliquid’s crypto perpetuals recorded $7.14 billion in 24-hour volume, placing trade.xyz’s $4.99 billion at about 41% of chain-wide trading.

Leading contracts by 24-hour volume and leverage:

• S&P 500: $571 million, up to 50x
• SK hynix: $375 million
• Nvidia: $257 million, up to 20x
• SanDisk and SpaceX: $247 million and $198 million

Trade.xyz launched in October 2025 as the first HIP-3 market allowing external teams to list contracts. It accounts for roughly 98% of HIP-3 volume and reports $650 billion in cumulative trading. Hyperliquid’s front end blocks US users. The CFTC aims to enable US-regulated venues to offer similar products domestically.

What Could the Lawsuit Mean for Hyperliquid?

The lawsuit does not affect current offshore trading on Hyperliquid. It determines whether US exchanges can list stock perps and whether ICE can onshore trade.xyz-style markets.

• If the alliance wins: single-stock perpetuals are classified as SEC-regulated security-based swaps, closed to retail. Kalshi and Coinbase would not list them. Offshore venues retain that flow. ICE’s US venue would lose stock perp listings, though crypto, commodity and currency perps remain permissible.
• If the CFTC wins: US exchanges can list stock perpetuals. Coinbase and Kalshi gain access to US retail that Hyperliquid does not serve. ICE could pursue bringing trade.xyz onshore, which aligns with the prior HYPE rally.

Near-term timing: ICE’s exchange still requires separate CFTC approval and has no launch date. The immediate milestone is the court’s decision on a stay, which could pause US listings before any contracts go live.

HYPE Price Analysis: Can It Get Back to $90?

HYPE retraced most of its ICE-related spike: $97.74 on October 29, then a pullback to $81.01 after the lawsuit, and recovery to $85.93, slightly above its 20-day EMA at $84.02. Key levels:

• $89.99: October 30 close; a daily close above signals a rebound toward $97.74
• $97.74: October 29 high, just under the $97.96 record
• $81.01: post-lawsuit low; a daily close below increases risk toward $74.45
• $74.45: October 24 low

The current dispute centers on US market access for stock perps. Hyperliquid’s offshore markets continue to execute about $5 billion daily without direct impact from the case.
