New York Federal Court Certifies Crypto Class Action With Modifications And Reserves Causation Question For Summary Judgment Proceedings

Duane Morris Takeaways: On March 6, 2025, Judge Katherine Polk Failla of the U.S. District Court for the Southern District of New York granted class certification with modifications in a case involving a stablecoin issuer's alleged issuance of unbacked or debased stablecoins in furtherance of an alleged scheme to manipulate the market prices for crypto commodities and futures in the litigation captioned In Re Tether & Bitfinex Crypto Asset Litigation, No. 19 Civ. 9236, 2026 WL 629826 (S.D.N.Y. Mar. 6, 2026). The ruling is significant as it shows that while crypto purchasers who file class action complaints alleging violations of the Sherman Act and Commodities Exchange Act may be able to satisfy Rule 23 so long as they offer reliable expert models on class-wide causation and damages and limit their proposed classes to purchasers who used fiat currency or stablecoins to make their purchases on domestic or stateless exchanges, such class actions may also be subject to dismissal based
