A little over a year ago, the federal government acquired a stake in Anthropic without paying a penny.
The shares were seized from associates of the crypto fraudster Sam Bankman-Fried. From there, they disappeared into a legal black hole.
As Anthropic rockets toward what could be the biggest IPO in history, those shares could now be worth billions of dollars.
Bankman-Fried’s own Anthropic stake was liquidated in the bankruptcy of his failed cryptocurrency exchange. The Anthropic equity owned by Caroline Ellison and Nishad Singh, two associates who invested alongside him, took a different path. The government seized those shares and sold them to existing Anthropic shareholders, according to a person familiar with the sale.
It’s still unclear whether the proceeds will be paid out to victims of the $11 billion fraud case, or if the feds will just keep the money.
It also remains a mystery which investors bought Singh’s and Ellison’s stock and how much they paid, but Anthropic shares have been on such a dizzying climb that it’s likely those investors made a killing on them.
Bankman-Fried was convicted in 2023 on fraud and money laundering charges and sentenced to 25 years in prison after the collapse of his cryptocurrency empire. Prosecutors said he used his crypto hedge fund, Alameda Research, to siphon billions of dollars from customers of FTX, his crypto exchange.
The story of the crypto criminals’ Anthropic shares is a tale with extraordinary elements, including one of the biggest financial frauds in modern history, a messy bankruptcy docket, and a company that experienced one of the fastest appreciations in business history as the world suddenly realized AI’s existential importance.
An intelligent investment
Bankman-Fried, Singh, and Ellison each invested in Anthropic’s 2022 Series B funding round. Bankman-Fried bought $500 million worth, which according to court records represented 13.56% of Anthropic at the time. Singh acquired $40 million in shares, and Ellison acquired $10 million in shares, court records reviewed by Business Insider show.
The artificial intelligence company’s valuation has soared over the past four years. On the secondary market, Anthropic has been valued at $1.5 trillion. It is the most valuable private company in the world, according to Crunchbase.
The Anthropic shares purchased by Singh and Ellison could together be worth between $4.17 billion and $5.03 billion today, based on the $965 billion valuation the company announced this May, according to Olav Sorenson, who teaches venture capital strategy at UCLA. Harrison Rolfes, an analyst at PitchBook, put the combined figure at $2.62 billion. If Anthropic went public at a $2 trillion valuation, the shares would be worth about $5.44 billion, Rolfes said.
Four of Bankman-Fried’s close friends and executives at his companies pleaded guilty as co-conspirators. Two of them, Singh and Ellison, testified against him.
Ellison was the CEO of Alameda Research, which traded and invested funds that belonged to FTX depositors. She was also Bankman-Fried’s on-and-off romantic partner. Singh, an FTX executive and early employee, helped hide the commingling of funds between the two companies.
After the collapse of FTX, Bankman-Fried’s Anthropic shares — which were owned by Clifton Bay, an entity affiliated with Alameda Research — ended up in bankruptcy court along with the other dredged-up remains of his companies. His Anthropic shares were liquidated to pay FTX’s creditors.
The estate in 2024 sold Bankman-Fried’s Anthropic shares to a few dozen buyers for a total of $1.3 billion, more than double what he paid. The largest stake went to an entity affiliated with the United Arab Emirates sovereign wealth fund, bankruptcy court filings show.
The feds take a stake in Anthropic
As part of their sentences, a judge required Singh and Ellison to forfeit their Anthropic shares, which prosecutors said could be considered proceeds of their crimes.
At Singh’s sentencing hearing, one of his attorneys, Andrew Goldstein, said Singh purchased his shares before participating in the criminal conspiracy and “he actually may have had a legitimate legal claim” to the shares but agreed to give them up as part of his plea agreement “because it was the right thing to do.”
Reached for comment for this story, Goldstein told Business Insider that Singh hopes the government is able to quickly distribute proceeds of the sale to FTX victims. An attorney for Ellison declined to comment.
A federal judge ordered Ellison’s and Singh’s Anthropic shares to be transferred to the federal government, which took ownership of Ellison’s shares in February 2025 and Singh’s in April of that year, according to previously unreported court records.
Ordinarily, victims of crimes are compensated through a restitution process, which is overseen by courts. But the number of potential FTX victims could be in the millions, prosecutors said in court filings. As a result, the judge ruled, victim compensation would be handled through a process called remission, which is overseen by the Justice Department.
During Ellison’s sentencing hearing, Justice Department prosecutors told the judge that the DOJ would either set up its own claims administration process to compensate victims, or work with the FTX bankruptcy process to identify victims and provide forfeited funds to them.
At the time, FTX’s bankruptcy process was in full swing. A Delaware court appointed Sullivan & Cromwell, the elite Wall Street law firm, to untangle the company’s assets, figure out who was owed money, and pay them.
The creditors in the FTX bankruptcy, prosecutors noted, largely overlapped with FTX’s victims. They were generally depositors, lenders, and investors who were defrauded by Bankman-Fried and other executives. Prosecutors said the Justice Department could work with the bankruptcy estate’s lawyers to get money back to them, as it had in previous large-scale financial frauds such as Bernie Madoff’s Ponzi scheme.
There was an unusual twist that set the FTX bankruptcy apart. Bankman-Fried’s investments — especially the Anthropic shares, along with some cryptocurrency — had grown substantially in value since FTX’s collapse. Earlier in 2024, the Sullivan & Cromwell lawyers who’d taken over FTX projected that all the creditors would be repaid in full, with interest.
The Marshals take control
While prosecutors said they intended to use Singh’s and Ellison’s Anthropic shares for remission, the Justice Department could technically do whatever it wanted with them, according to Duncan Levin, a white-collar defense attorney who teaches a course on forfeiture at Harvard Law School.
“It’s a very opaque process,” he said. “It’s completely at the discretion, by law, of the attorney general of the United States.”
Typically, when the feds seize shares of private companies through criminal asset forfeiture, they send the shares to the US Marshals Service Complex Assets Unit for liquidation. The unit tries to value the shares as any other investor would, said Michael Bachner, a white-collar criminal and securities litigation attorney.
“They may look to: What would an institutional purchaser pay for these securities?” Bachner said. “Are there funds that are valuing the securities? Is there a secondary market already out there?”
For the sale of the Anthropic shares, timing was crucial. The Marshals Service is supposed to preserve as much value as possible, Bachner said. By the time the feds got hold of the shares, Anthropic had become an economy-shifting AI giant. In its March 2025 Series E fundraising round, Anthropic was worth $61.5 billion. By its Series G round at the start of 2026, it was worth $380 billion.
At the same time, each fundraising round diluted the Series B shares. The FTX estate told the bankruptcy court that Bankman-Fried’s shares, which in 2022 represented 13.56% of Anthropic, represented 7.84% of the AI company in January 2024.
The Marshals Service sold Singh’s and Ellison’s shares to existing Anthropic investors sometime last year, according to the person with knowledge of the sale.
It’s not clear when exactly the agency sold the shares, to which investors, how those investors were chosen, at what price the shares were sold, or how much money the government made in the sale. Depending on when they were sold in 2025, the combined shares could have been worth between $300 million and $1.1 billion, according to Sorenson, the UCLA professor. Rolfes, the PitchBook analyst, estimated a range between $250 million and $630 million, depending on the timing.
The Marshals Service declined to comment. A representative for the Justice Department said information about asset sales and victim compensation is confidential.
The revenue from the sale of Singh’s and Ellison’s Anthropic shares doesn’t appear to have been transferred to the FTX estate as of the end of June this year, according to bankruptcy court filings from the estate, which continues to compensate victims and creditors.
The FTX estate received $638 million last year from assets seized by the Justice Department, according to the estate’s annual report for 2025. Other filings show that nearly all of that amount came from the sale of Robinhood shares previously owned by Bankman-Fried. The estate expects to receive about $400 million more from the government at some point in the future, according to the annual report. That would include proceeds from cryptocurrency and other investments made by Bankman-Fried.
One of Bankman-Fried’s victims, Sunil Kavuri, told Business Insider that the Justice Department should use the proceeds of Ellison’s and Singh’s Anthropic shares to compensate victims. It would be “diabolical” for the government to hold onto the proceeds, he said.
Victims haven’t actually been made whole, he said, because the bankruptcy court calculated the losses of FTX depositors using the time of FTX’s bankruptcy declaration, when crypto prices were at a low ebb. Kavuri previously argued in bankruptcy court that the FTX estate should have held on to its Anthropic shares for longer to take advantage of the company’s swift growth.
Representatives for the FTX estate declined to comment. The Justice Department spokesperson said the matter was ongoing, and that the DOJ “prioritizes victim compensation from forfeiture and takes all steps to ensure forfeited funds are provided to victims.”
The government could end up just keeping the money, Bachner said.
“They’ve invested millions and millions and millions of dollars in prosecuting Bankman-Fried. And they want to get at least reimbursed for their costs, so sometimes they’ll do that,” he said. “It’s really a unilateral government decision.”
