Three crypto executives extradited from Singapore appeared in federal court in Oakland as the U.S. Department of Justice expanded its probe into alleged wash trading that now targets 10 foreign nationals tied to four market‑maker firms. Prosecutors say the cases involve Gotbit, Vortex, Antier and Contrarian, and allege coordinated schemes to inflate token prices and volumes so assets looked more liquid and in demand than they actually were.
The enforcement action traces to an undercover operation first unsealed in October 2024. According to the DOJ, a Gotbit‑related indictment was filed in March 2025, a Vortex case followed in August 2025, and a Contrarian‑Antier case was added in September 2025, building on the initial charges revealed in 2024. In that earlier phase, U.S. authorities charged 18 individuals and entities in a global operation targeting widespread crypto investment fraud and market manipulation. The Securities and Exchange Commission has brought parallel actions and described “market‑manipulation‑as‑a‑service” offerings tied to Gotbit and related actors.
U.S. officials say Vortex CEO Gleb Gora, Contrarian CEO Manu Singh and Contrarian employee Vasu Sharma were arrested in Singapore in October 2025, extradited to the United States, and made their first appearances in California federal court this week.
Indictments allege tactics including wash trading, matched orders and other prearranged transactions designed to manufacture fake volume, prop up token prices and create the appearance of organic investor interest before insiders sold into the market. These charges come after earlier guilty pleas and settlements: Gotbit agreed to cease operations and to forfeit roughly $23 million in seized cryptocurrency under a plea deal over alleged manipulation of thinly traded tokens. Separately, UAE‑based CLS Global pleaded guilty in Massachusetts to manipulating trading in NexFundAI — an FBI‑created token used to expose fraudulent market‑making — and agreed to pay a $428,059 fine, forfeit funds on multiple exchanges and accept a U.S. trading ban.
Prosecutors and regulators have repeatedly warned that wash trading remains a persistent problem in crypto markets because artificial volume can mislead investors about true liquidity and demand.
