Three crypto executives extradited from Singapore appeared in federal court in Oakland Monday as U.S. prosecutors expanded a wash‑trading probe that now charges 10 foreign nationals linked to four market‑maker firms. The Justice Department says the cases involve Gotbit, Vortex, Antier and Contrarian and allege coordinated schemes to inflate token prices and volumes so assets appeared more liquid and in demand than they 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 filed 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, and the Securities and Exchange Commission brought parallel actions describing “market‑manipulation‑as‑a‑service” offerings tied to Gotbit and associated actors.
The DOJ says 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 a California court on Monday.
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 follow prior guilty pleas and penalties: 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. In a related matter, UAE‑based CLS Global pleaded guilty in Massachusetts to manipulating trading in NexFundAI (an FBI‑created token used to expose fraudulent market‑making), agreed to pay a $428,059 fine, forfeit funds on multiple exchanges and accept a U.S. trading ban.
U.S. prosecutors and regulators have repeatedly warned that wash trading remains a persistent problem in crypto markets because artificial volume can mislead investors about liquidity and demand.
