Three cryptocurrency executives extradited from Singapore appeared in federal court in Oakland on Monday as US Department of Justice prosecutors broadened a wash-trading case that now involves 10 foreign nationals connected to four crypto market-making companies. The court appearances represent the latest development in a US crackdown on alleged manipulation in digital asset markets. The enforcement effort originated with an undercover operation whose charges were first unsealed in October 2024.
The cases center on four firms — Gotbit, Vortex, Antier, and Contrarian — over conduct dating back to 2018. Prosecutors allege the companies engaged in schemes to artificially inflate token prices and trading volumes through coordinated transactions. The goal, according to the DOJ, was to make digital assets appear more liquid and in demand than they actually were.
The indictments were filed in stages: a Gotbit-related indictment in March 2025, a Vortex case in August 2025, and a combined Contrarian-Antier case in September 2025. These built upon the initial October 2024 enforcement action, in which US authorities charged 18 individuals and entities in a global operation targeting crypto investment fraud and market manipulation. A parallel action by the United States Securities and Exchange Commission at that time described so-called market-manipulation-as-a-service offerings linked to Gotbit and associated actors.
Vortex CEO Gleb Gora, Contrarian CEO Manu Singh, and Contrarian employee Vasu Sharma were arrested in Singapore in October 2025 before being extradited to the United States. All three made their first appearances in a California court on Monday. The indictments describe tactics including wash trading, matched orders, and other prearranged transactions intended to generate artificial volume and support token prices before insiders sold their holdings into the market.
Earlier phases of the crackdown produced guilty pleas and financial penalties. Gotbit agreed to cease operations and forfeit approximately $23 million in seized cryptocurrency as part of a plea deal related to alleged manipulation of thinly traded tokens. The agreement marked one of the more significant outcomes of the broader enforcement campaign against coordinated crypto market manipulation.
In a related case concluded in January, CLS Global, based in the United Arab Emirates, agreed to plead guilty in Massachusetts to charges of manipulating trading in NexFundAI, a token created by the FBI specifically to expose fraudulent crypto market-making schemes. As part of its agreement with prosecutors and the SEC, CLS Global agreed to pay a fine of $428,059, forfeit funds held on multiple exchanges, and accept a ban on trading in US markets.
US prosecutors and regulators have consistently described wash trading as a persistent problem across crypto markets, arguing that fabricated volume can mislead investors regarding the genuine liquidity and demand for a given asset. The series of cases signals continued regulatory focus on market integrity in the digital asset sector, with enforcement actions spanning multiple jurisdictions and involving cooperation between US agencies and foreign authorities.
