NFT wash trading

As of September 2026: The Second Circuit vacated the OpenSea insider trading and money laundering convictions of Nathaniel Chastain on July 31, 2025, and press reports in January 2026 said prosecutors then agreed to defer prosecution and dismiss the case. Treasury's May 2024 assessment has not been updated. No US prosecution that we could verify has charged laundering through NFT wash trading as such; the cases below involve related NFT frauds.

What is NFT wash trading?

A non-fungible token (NFT) is a unique digital item recorded on a blockchain, such as an image, a collectible or a game asset. Unlike a share of stock, no two are identical, so there is no single market price. Each one is worth what someone will pay for it.

A wash trade is a sale where the buyer and seller are really the same person, acting through two or more accounts. In traditional markets it fakes activity. In NFT markets, the same move can serve two different goals. One is market manipulation: making a token look popular so real buyers pay more. The other is laundering: making illicit crypto look like the proceeds of an ordinary sale.

This page is about the second goal, and it is worth being plain about how far the evidence goes. Wash trading for profit is well documented. Wash trading to launder crime proceeds is described by regulators and researchers, but published enforcement examples are thin. The US Treasury said so itself when it published its first NFT risk assessment in May 2024.

How does NFT wash trading work?

Treasury’s assessment describes the core move as “self-laundering.” The steps below follow that description at a conceptual level.

1. A person holds crypto that came from a crime, such as a scam, a theft or a ransom.
2. They use it to buy an NFT, often on an open marketplace.
3. They then sell the NFT to a second wallet under their own control, at a price that may be many times higher. Each sale is recorded permanently on the blockchain.
4. The token may then be sold on to a real buyer, an unwitting one, who pays with funds that have no link to the original crime.
5. The seller can now point to the on-chain record and say the money came from selling an NFT.

Treasury also describes a second use: speed. Criminals who steal an NFT, or who use one as a stepping stone, may resell it fast, sometimes at a loss, to add “hops” that make tracing harder. The report adds that illicit actors may use several platforms or accounts so that no single platform sees the pattern, and may then run the crypto through a mixer before cashing out.

Why NFT wash trading works

The first gap is price. Treasury noted that it can be hard to tell whether an NFT is priced fairly or is part of price manipulation or laundering, and that criminals “may also easily inflate or reduce the price” of an NFT to hide the exchange of illegitimate funds. Art has the same weakness, and Treasury said the risk may be greater for NFTs because they move over a blockchain with none of the physical limits of the traditional art market. Prices can also swing hard. Treasury cited one industry report showing the average NFT price fell from $791.84 at its August 2021 peak to $38.17 in September 2023. In a market like that, an odd price is not automatically a red flag.

The second gap is identity. Treasury said law enforcement has observed that illicit actors take advantage of the fact that many NFT platforms do not require customer information. Anyone can create a wallet in seconds, so a second “buyer” costs almost nothing.

The third is the blur between manipulation and laundering. Some researchers estimate wash trading is very common. Treasury cited one study that concluded 58 percent of Ethereum-based NFT trades in 2022 were associated with wash trading, with over $30 billion in volume linked to it. That is a single study’s estimate, and it measures wash trading in general, not laundering of crime proceeds. But the volume creates cover. A platform full of self-trades makes any one self-trade look ordinary.

The fourth gap is that regulation has lagged. Treasury said NFT platforms differ in whether they apply the anti-money laundering rules that a bank or a regulated crypto exchange would. That varies with how each platform is built and what it does.

What the enforcement record shows

Treasury said it found few case examples partly because cases take years to conclude, and said this “does not necessarily reflect the level of risk.” Here is what is on the record.

Measured flows. Chainalysis, in a February 2022 report, looked at Ethereum NFT sales. It found 262 users who had sold an NFT to a self-financed address more than 25 times. Of these, 110 profited by a combined $8.88 million and 152 lost a combined $417,000, for a net profit of about $8.46 million. So wash trading could pay, but most participants lost money. On laundering, Chainalysis counted only about $1 million of illicit crypto entering NFT marketplaces in Q3 2021 and nearly $1.4 million in Q4, and called this “a drop in the bucket” beside the $8.6 billion it saw laundered through crypto that year.

The OpenSea case. The best-known NFT prosecution with a laundering charge was not a wash-trading case. On June 1, 2022, federal prosecutors in Manhattan charged Nathaniel Chastain, a former OpenSea product manager, with wire fraud and money laundering. They alleged he bought dozens of NFTs shortly before OpenSea featured them on its homepage, then sold them at two to five times the price, using anonymous wallets and accounts to conceal it. Treasury reported that he was sentenced to three months in prison in August 2023. On July 31, 2025, the Second Circuit vacated his convictions because of an error in the jury instructions about what counts as property under the wire fraud statute. Press reports in January 2026 said prosecutors agreed to defer prosecution rather than retry him. The case shows how concealment through fresh wallets can be charged as laundering. It also shows that the law here is still being tested.

Rug pulls and theft. Treasury’s assessment also lists NFT projects that were allegedly frauds, including a “rug pull” where creators take investors’ money and shut down the project. Examples include Baller Ape (charged June 2022, about $2.6 million) and Mutant Ape Planet (charged January 2023, over $2.9 million). Treasury also described the creators of a fake NFT platform who stole high-value NFTs worth about $200,000 and laundered the funds through the Tornado Cash mixer. In those cases the laundering was mostly ordinary crypto laundering that happened to sit next to NFTs.

Wash trading of tokens. On October 9, 2024, the US Attorney’s Office in Boston announced charges against 18 individuals and entities. These included “market makers,” firms hired to make tokens look active. It called them the first criminal charges against financial services firms for wash trading in the crypto industry. FBI agents had created a token of their own as bait, and more than $25 million in crypto was seized. These were fungible coins, not NFTs, and the charges were fraud and manipulation. Still, prosecutors made clear that wash trading is a crime they will pursue in crypto.

How NFT wash trading gets caught

The blockchain works against the launderer here. Every sale is public, permanent and searchable, so the useful question is not “was there a sale” but “who funded both wallets.”

Analysts follow the money into each wallet. If the seller’s wallet and the buyer’s wallet were both funded by the same source, or by each other, that is a “self-financed” pattern. Chainalysis used this test in its 2022 report, and 25 or more such sales was its threshold for calling a trader a habitual wash trader. Other signals include prices with no bidding history, repeat trades of the same token in a tight loop, and proceeds that move at once to a mixer or an unregulated exchange.

Platforms are the next line. Treasury’s assessment listed tools NFT platforms can use, including controls on how often a user can trade to curb wash trading, analytics that rate the risk of wallet addresses, and screening for sanctions exposure. It noted that platforms can use them voluntarily or to meet legal obligations. Firms that fall under money transmitter or virtual asset service provider rules must also file suspicious activity reports.

Finally, prosecutors use ordinary tools on a new asset. Fraud, laundering and manipulation statutes apply to the conduct rather than the technology, and undercover operations such as the FBI’s 2024 token show that agents will build the market themselves to catch the people wash trading it. The Chastain reversal is a reminder that some theories will not survive appeal, so the strongest cases usually rest on plain fraud with a clear victim.
