US prosecutors have decided not to retry the insider trading case against a former manager at OpenSea, Nathaniel Chastain. This decision follows a federal appeals court’s ruling in July that reversed his conviction. The prosecutors entered into a one-month deferred prosecution agreement, and after the agreement expires, the case will be formally dismissed.

Deferred Prosecution Agreement Reached

In a letter to the court, Manhattan US Attorney Jay Clayton confirmed the agreement. Chastain had already served part of his sentence, including three months in prison, and had paid a $50,000 fine. He also agreed to forfeit 15.98 Ether (ETH), which prosecutors said was obtained through his insider trading activities.

“The interest of the United States will be best served by deferring prosecution of this matter,” Clayton stated. The agreement ensures that Chastain will not face any further legal supervision, and he may seek to recover the financial penalties imposed after his initial conviction. The decision marks the end of a high-profile case that drew attention due to its focus on digital asset trading.

Appeals Court Overturns Conviction

Chastain’s conviction for wire fraud and money laundering was overturned by a federal appeals court in July 2025. The court ruled that the jury had been improperly instructed during the trial. Furthermore, it concluded that NFT homepage data, involved in the case, lacked commercial value and thus did not meet the criteria for wire fraud under federal law.

Chastain had been accused of using his position at OpenSea to purchase NFTs that would later be featured on the platform’s homepage. He then sold these NFTs once their visibility on the site led to a price increase. This case marked the first instance of insider trading involving digital assets, raising questions about how existing laws apply to NFTs.

OpenSea Case Adds to Crypto Legal Shifts

The decision to abandon the case aligns with a broader trend in US crypto regulation. Following the leadership change at the Securities and Exchange Commission (SEC), crypto enforcement actions have decreased. A report from Cornerstone Research revealed that in 2025, the SEC launched 60% fewer crypto-related cases than the previous year. This change suggests a shift in regulatory focus toward more straightforward cases of fraud.

This adjustment in enforcement strategy is evident in Chastain’s case and in the SEC’s approach under the leadership of Paul Atkins. The agency is now concentrating on cases with clear evidence of investor harm, rather than testing broad legal theories.
