Tether Sued Over $42.4M USDT Freeze Before Warrant
Tether is facing a federal lawsuit in the Southern District of New York over the alleged pre-warrant freeze of 42,417,785.62 USDT. Plaintiffs Nutthawat Rukthammachalern and Natthawat Kasamvilas filed the complaint on August 31, 2026, against four Tether entities.
The complaint alleges that Tether blacklisted 10 Ethereum addresses on October 30, 2025, after an informal request from a Homeland Security Investigations agent. The plaintiffs say no warrant, subpoena or court order existed when Tether froze the USDT. They claim to have acquired the tokens on the secondary market and seek removal of the blacklist, an injunction preventing the tokens from being burned or transferred, damages and income linked to the reserves backing the frozen USDT.
A federal magistrate judge issued seizure warrant No. 5:26-MJ-1267-JG on February 19, 2026, 112 days after the alleged freeze. Five days later, prosecutors in North Carolina announced the seizure of more than $61 million in USDT allegedly tied to cryptocurrency investment scams. The US Justice Department said Tether helped transfer the assets, but available information does not establish that all of those funds were connected to this lawsuit.
The claims against Tether have not been adjudicated. Tether has previously said it cooperates with law enforcement and has frozen more than $4.4 billion in assets, including over $2.1 billion linked to US authorities. The case could increase scrutiny of stablecoin issuer powers, compliance procedures and USDT counterparty risk, but it does not currently indicate a broader USDT solvency problem.
Neutral
The direct price impact on USDT is likely to be neutral. The lawsuit concerns an alleged freeze of specific addresses and Tether’s cooperation with law enforcement, rather than a shortfall in reserves or a redemption failure. USDT remains designed to trade near $1, and the article provides no evidence of a broader solvency problem.
In the short term, the case could prompt isolated concerns among traders and increase scrutiny of frozen wallets, exchange compliance and counterparty risk. That could cause temporary liquidity or sentiment effects if additional addresses are linked to the dispute, but it is unlikely by itself to create sustained USDT price dislocation.
Over the longer term, a court ruling against Tether could pressure the issuer to clarify its freezing procedures and could influence stablecoin regulation. A ruling supporting Tether’s actions could reinforce the role of centralized stablecoins in law-enforcement seizures. Neither outcome necessarily changes USDT’s market value immediately, although a wider loss of confidence in Tether’s reserves or redemption process would be a materially bearish development. Traders should monitor court filings, official seizure records, exchange restrictions and any deviation of USDT from its dollar peg.
