The first NFT “insider trading” conviction just got thrown out, and the implications could reach far beyond one OpenSea employee.

Nate Chastain was once the poster child for the DOJ’s push to bring traditional market policing into the world of digital assets. As OpenSea’s former head of product, he was accused of quietly buying NFTs just before featuring them on the platform’s homepage —a move that reliably drove their prices up — and then selling for a quick profit. Chastain made about $57,000 from buying and selling 15 NFTs, court papers show. For each trade, he used an anonymous account in an attempt to conceal his activity.

In 2023, prosecutors secured a guilty verdict for wire fraud and money laundering, calling it the “first-ever NFT insider trading case.” Chastain was sentenced to three months in prison, and the case became a landmark moment for defining what counts as fraud in crypto markets.

Yesterday, the U.S. Court of Appeals for the Second Circuit vacated Nate Chastain’s wire fraud and money laundering convictions, ruling that OpenSea’s confidential homepage-pick information didn’t qualify as “property” under federal fraud statutes. The decision is a sharp rebuke to the DOJ’s attempt to stretch legacy laws to fit crypto-era behavior and raises questions about how far prosecutors can go in future digital asset cases.

To break down what this means for the case and future enforcement, we spoke with Carlo D’Angelo, the attorney and writer behind The DeFi Defender, who attended the trial and has followed this case from day one.

Matt Medved: What are the biggest legal implications of this ruling?

Carlo D’Angelo: In a federal wire fraud case, the government bears the burden of proving that the defendant engaged in a scheme to defraud the victim out of either money or property. The Chastain NFT “insider trading” case tested the limits of whether confidential information qualifies as “property” under the wire fraud statute. Chastain argued that the NFT listing information did not qualify as property as a matter of law because (1) it lacked commercial value to OpenSea and (2) the company failed to take meaningful steps to safeguard its confidentiality. The defense objected at trial to a jury instruction that defined “property” as including “confidential business information” acquired or created for a business purpose — even if the information lacked commercial value to the company.

On appeal, Chastain argued that he was prejudiced by the jury instructions because the government did not prove that the featured NFT information constituted OpenSea’s property, and the jury may have convicted him based on conduct it deemed unethical rather than meeting the legal standard for wire fraud. The Second Circuit reversed Chastain’s wire fraud conviction because the jury instruction caused him to be convicted based on the misappropriation of information — labeled as “property” — that lacked any commercial value.

The Second Circuit noted that if the wire fraud statute punished conduct based solely on departures from traditional notions of honesty and fair play, then “nearly any deceptive act could be deemed criminal.”

“We agree with Chastain that confidential business information must have commercial value to a company to qualify as its property under the wire fraud statute. The district court erred by instructing the jury that it could find Chastain guilty of wire fraud even if it found that he misappropriated information that lacked commercial value to OpenSea.”

How much does this decision undermine the DOJ’s use of wire fraud as a catch-all in crypto cases?

The Second Circuit’s holding sharply limits the government’s ability to bring insider trading wire fraud charges based solely on the misuse of confidential information, making clear that only information with demonstrable commercial value qualifies as “property” under the code. As a consequence, the Second Circuit’s decision in Chastain significantly undercuts the DOJ’s use of wire fraud as a catch-all tool in crypto-related prosecutions by reaffirming that the statute applies only to schemes targeting traditional property interests — not merely unethical or deceptive conduct involving confidential information lacking commercial value.

Could this open the door to appeals in other crypto fraud cases?

Only to the extent those convictions hinged on similarly broad interpretations of “property,” especially those built on misappropriation theories involving intangible information or reputational harm rather than financial loss. More broadly, the Second Circuit’s opinion casts doubt on how far insider trading prosecutions can stretch in both crypto and traditional market cases by making clear that access to nonpublic information alone is not enough to support criminal liability. Unless prosecutors can tie the nonpublic information to a tangible economic “property” interest, they may fail to meet the essential elements required for a wire fraud conviction.

How should platforms rethink internal policies after this reversal?

For NFT platforms like OpenSea, the Chastain holding serves as a clear warning to tighten internal policies and define enforceable rules around access and use of nonpublic information — particularly if they expect unauthorized use of such information to lead to legal consequences.

What does this mean for Chastain and his case going forward?

The Second Circuit’s reversal means that Chastain’s conviction for wire fraud and money laundering has been vacated. His case is now remanded back down to the district court for further proceedings. Although a remand back to the district court opens the door for a possible retrial, that’s unlikely given that the government now faces a higher burden of proof. Prosecutors would now need to prove that the information Chastain allegedly misused had some tangible commercial value to OpenSea. If the government lacks confidence that its evidence can meet that threshold, it may opt to either drop the case entirely or explore a narrower theory of prosecution — though its legal avenues are now significantly limited by the Second Circuit’s holding.
