Federal prosecutors in New York’s Southern District have called for a new trial for MIT alumni Anton and James Peraire-Bueno, who are accused of orchestrating a $25 million

maximal extractable value (MEV) scheme. The retrial is expected to take place in late February or early March 2026

. The first trial concluded with a mistrial on November 7, 2025, after jurors could not reach a unanimous decision despite three days of discussion

[CryptoNews]

. As the first criminal case focused on MEV manipulation, the proceedings have ignited debate about the scope of legal responsibility in decentralized finance

The brothers are charged with wire fraud, conspiracy to commit wire fraud, and money laundering, each carrying a possible 20-year prison sentence if found guilty

. Prosecutors allege the Peraire-Bueno brothers manipulated Ethereum’s validator layer to reorder transactions and divert funds, describing it as “the first exploit of its nature”

The defense maintains that their automated bots operated within Ethereum’s established protocols, characterizing their actions as “legitimate competition” in an “intensely competitive” environment

The mistrial underscored the challenges of applying conventional fraud laws to blockchain systems. Jurors reportedly found it difficult to interpret technical evidence and legal standards, including whether “wrongful means” required intent to break the law

[Coinotag]

. The jury’s final note described the process as emotionally draining, with members experiencing sleeplessness and anxiety

[CryptoNews]

. U.S. District Judge Jessica Clarke refused to prolong deliberations or substitute a departing juror, stating, “This is their 11th note, no progress. I am going to declare a mistrial”

[CryptoRank]

This case has significant ramifications for the broader crypto sector. The Department of Justice has stressed the importance of tackling MEV exploits, which are increasingly seen as a threat to blockchain scalability

[Coinotag]

. Research from Flashbots shows that MEV bots now account for more than half of the gas consumption on Ethereum rollups such as Base and OP Mainnet

[CryptoRank]

. Legal analysts caution that the verdict could shape future regulatory strategies for MEV, with a conviction possibly discouraging similar activities and an acquittal potentially emboldening others

[Coinotag]

The prosecution’s insistence on a 2026 retrial highlights the Justice Department’s resolve to pursue digital asset-related offenses. The upcoming trial is expected to focus more closely on technical evidence and the question of intent, with both sides likely to rely on expert witnesses to explain blockchain operations

[Coinotag]

. Meanwhile, Ethereum developers are fast-tracking solutions to reduce MEV risks, such as proposer-builder separation (PBS), which simulations indicate could cut down on exploitable opportunities by as much as 90%

[Coinotag]

The ongoing legal dispute involving the Peraire-Bueno brothers highlights the ongoing struggle between technological innovation and regulatory oversight in the crypto space. Their defense, supported by advocacy group Coin Center, warns that criminalizing unconventional validation techniques could destabilize decentralized networks

[CryptoRank]

. On the other hand, the DOJ argues that the exploit compromised the integrity of Ethereum, setting a legal precedent for prosecuting MEV-related fraud
