Appeal Successfully Reverses Insider Trading Conviction for Ex-OpenSea Director
In a surprising turn of events, the US District Court for the Southern District of New York has overturned the convictions of Nathaniel Chastain, a former manager at the popular NFT marketplace OpenSea, for alleged wire fraud and money laundering. This decision was made on appeal, citing flawed jury instructions.
Chastain, who served as a product lead at OpenSea, was accused of using insider knowledge to buy NFTs, knowing that certain collections would be featured on OpenSea’s homepage. This, in turn, allegedly boosted the value of these NFTs. He was convicted and sentenced in 2023, but upon appeal, the 2nd U.S. Circuit Court of Appeals in Manhattan reversed the conviction in 2025.
The appellate court found that the jury had been given incorrect instructions, allowing them to convict Chastain for unethical behaviour rather than criminal wrongdoing. The judges agreed with Chastain’s argument that this was an error since the misappropriated intangible interest wasn’t connected to traditional property rights, which are necessary for such a fraud conviction.
However, the court did uphold the conviction for market manipulation. This decision was based on Chastain's personal purchasing of numerous tokens before listing them on the homepage, which allegedly allowed him to manipulate their prices.
It's important to note that the jury was not properly instructed on the requirements for criminal activity related to fraud and laundering when it comes to property law. The court recognized that the jury may not have found the defendant guilty if it had been properly instructed that fraud requires the appropriation of a property interest rather than unprofessional business conduct.
As of August 2023, OpenSea's active users count is growing amid the buzz surrounding its native token. However, no further details about the specific NFTs Chastain allegedly bought before featuring them on OpenSea’s homepage for profit were provided.
The decision opens the possibility of a retrial for Chastain in the Southern District of New York court. Readers are reminded to verify information and consult with a professional before making any financial decisions based on the content.
