U.S. federal prosecutors have charged ten individuals linked to four crypto market-making firms over alleged wash trading and price manipulation schemes.
The indictments, unsealed on March 30, 2026, by the U.S. Attorney’s Office for the Northern District of California, accuse the defendants of using coordinated trading activity to create misleading market signals across digital asset platforms.
Market Makers Accused of Manipulation
According to prosecutors, the defendants used trading bots to generate artificial volume and inflate token prices.
The activity allegedly created the appearance of demand, encouraging investors to buy before prices were sold into by the same operators.
Authorities have seized more than $1 million in cryptocurrency. Several defendants are in custody, while others have already pleaded guilty.
The charges involve individuals connected to Gotbit, Vortex, Contrarian, and Antier Solutions Private Limited.
-
Gotbit: Named defendants include Antoine Tsao, Ian Sofronov, and Nemanja Popov. Tsao and Popov have pleaded guilty and have been sentenced.
-
Vortex: Led by Gleb Gora, along with Sergei Ryzhkov and Michael Vogel. Prosecutors allege the firm ran coordinated pump-and-dump strategies.
-
Contrarian and Antier: Defendants include Manu Singh, Kushagra Srivastava, Vasu Sharma, and Sabby Singh.
These firms marketed themselves as liquidity providers, offering services to crypto projects seeking trading activity and exchange visibility.
Prosecutors allege that, in practice, some of these services involved artificial trading designed to simulate organic demand.
Key Allegations From the Indictment
Federal grand juries returned three indictments outlining a similar pattern of activity across the firms.
The core allegation is wash trading—transactions where the same entity, or coordinated parties, act as both buyer and seller to create the illusion of market activity.
According to the filings, the schemes involved:
-
Automated bots executing large volumes of trades with no economic purpose.
-
Coordinated price increases followed by sell-offs of held tokens.
-
Targeting low-liquidity tokens where price impact could be amplified.
-
Inflating metrics used by listing platforms and exchanges.
Authorities also conducted an undercover operation called “Token Mirrors” in which they created test tokens to engage with these services.
The resulting evidence contributed to charges of wire fraud and conspiracy, each carrying potential prison sentences of up to 20 years.
Three defendants—Gora, Singh, and Sharma—were arrested in Singapore in October 2025 and later extradited to the United States.
Ongoing Scrutiny of Market-Making Practices
Market makers play a legitimate role in financial markets by providing liquidity. However, in crypto, the line between liquidity provision and manipulation has been a recurring issue.
Past enforcement actions, including cases in 2024 involving similar firms, highlighted the use of automated systems to generate artificial volume and influence market perception.
This latest set of charges continues that pattern, focusing on firms operating across multiple jurisdictions.
Binance Tightens Market Maker Rules
Separately, Binance announced new requirements for market makers on March 25, shortly before the indictments were unsealed.
The exchange now requires:
- Full disclosure of market maker identities and legal entities.
- Transparency around contractual terms with token issuers.
- A ban on profit-sharing or guaranteed-return agreements.
Binance also outlined several behaviors it considers high risk, including:
- Artificial volume generation.
- One-sided trading patterns.
- Coordinated selling across platforms.
- Large volumes with limited price movement.
The exchange said it would take action, including blacklisting, against entities found violating these standards.
