Federal prosecutors charge 10 in crypto market manipulation scheme as three executives extradited to US
Three leaders from cryptocurrency market-making firms Gotbit, Vortex, Contrarian and Antier have been brought to America in a coordinated enforcement action against what authorities describe as "market‑manipulation‑as‑a‑service."
A trio of cryptocurrency industry executives who were extradited from Singapore made their initial appearances in an Oakland federal courthouse on Monday, as federal prosecutors broadened their wash-trading investigation to encompass 10 foreign nationals connected to four cryptocurrency market-making firms.
These courtroom proceedings represent the most recent development in a United States enforcement campaign against purported wash trading activities in cryptocurrency markets, which kicked off with an undercover investigation made public in October 2024, as detailed in a Tuesday statement issued by the US Justice Department (DOJ).
According to the DOJ's announcement, the legal actions targeting Gotbit, Vortex, Antier and Contrarian for activities stretching back to 2018 revolve around coordinated schemes designed to artificially inflate token valuations and trading volumes through synchronized trading patterns that created false impressions of liquidity and genuine market demand for these digital assets.
The DOJ's statement reveals that the indictment associated with Gotbit was submitted to the court in March 2025, with the Vortex-related prosecution following in August 2025 and the combined Contrarian-Antier case arriving in September 2025, all part of an expanding international enforcement initiative that saw its initial charges revealed to the public in October 2024.
During that initial enforcement wave, American authorities brought charges against 18 individuals and corporate entities as part of a worldwide operation aimed at combating extensive cryptocurrency investment fraud and market manipulation activities, accompanied by a simultaneous United States Securities and Exchange Commission enforcement action that detailed "market-manipulation‑as‑a‑service" business models operated by Gotbit and associated participants.
According to the Justice Department's disclosure, Vortex chief executive officer Gleb Gora, Contrarian chief executive officer Manu Singh and Contrarian staff member Vasu Sharma were taken into custody in Singapore during October 2025, subsequently extradited to the United States, and presented themselves for their initial judicial proceedings at a California federal court on Monday.
DOJ builds on multi-year crypto wash trading crackdown
The criminal indictments outline specific methods including wash trading practices, matched order arrangements and additional prearranged transaction schemes created to manufacture artificial trading volume, prop up token valuations and manufacture the appearance of genuine investor demand before company insiders liquidated their holdings into the marketplace.
These latest enforcement actions build upon previous guilty pleas and financial sanctions in connected prosecutions, including the case against Gotbit, which accepted terms to shut down its operations and surrender roughly $23 million in confiscated cryptocurrency assets as components of a negotiated plea arrangement concerning alleged manipulation activities involving tokens with limited trading volume.
In a separate but related legal matter concluded in January, CLS Global, a company based in the United Arab Emirates, entered an agreement to plead guilty in Massachusetts to criminal charges of engaging in manipulation of trading activity in NexFundAI (NEXF), a token created by the FBI specifically to uncover fraudulent cryptocurrency market making operations, and committed to paying a $428,059 monetary penalty, surrendering funds held across multiple trading platforms and accepting a prohibition on United States trading activities as elements of its settlement agreement with federal prosecutors and the SEC.
Federal prosecutors and regulatory officials have consistently characterized wash trading as an ongoing challenge within cryptocurrency marketplaces, maintaining that artificially generated trading volume has the potential to deceive investors regarding actual liquidity conditions and authentic market demand.
