Sam Bankman-Fried's law professor parents have stuck close by their son through the fallout from FTX's collapse. Here's what we know about them.

Bankman-Fried, who faces multiple fraud charges tied to the spectacular collapse of FTX, was released on $250 million bail Thursday, shortly after he landed in the US after being extradited from the Bahamas.

As part of his bail terms, Bankman-Fried, who also cofounded crypto trading firm Alameda Research, is required to stay at his parents' home while he awaits trial.

His parents, Joseph Bankman and Barbara Fried, live in a multimillion-dollar home in Stanford, in the San Francisco Bay Area, according to news reports and state records.

Zillow estimates the value of the five-bedroom home at about $4 million, while Redfin's estimate is $3.1 million.

Bankman-Fried was arrested in the Bahamas on December 12. The next day, his parents attended his court hearing in Nassau, the capital of the Bahamas, where he was denied bail. They later visited the prison where their son was being held.

The Wall Street Journal reported the couple as telling friends that they expected their son's legal bills to wipe them out financially.

Bankman is a professor of law at Stanford University. He's described in his biography on Stanford's website as a "leading scholar in the field of tax law."

He's also a clinical psychologist, having earned an degree in the field from Palo Alto University. New York Magazine reported that he's offered lunchtime sessions to first-year Stanford law students on cognitive behavioral therapy and managing anxiety.

A spokesperson for Bankman told The Wall Street Journal that Bankman was a paid FTX employee for 11 months, in which time he worked on charitable projects, and was not involved in running the company.

Bankman helped FTX recruit its first lawyers, joined FTX executives in meetings on Capitol Hill, and advised his son as he prepared to testify before the House Financial Services Committee, The New York Times reported. Bankman regularly flew to the Bahamas, per The Times.

The Times also reported that Bankman organized an FTX event at Miami Heat's FTX Arena in March, where local high school students pitched business ideas to a panel of judges.

A tax-policy class that Bankman was set to teach in the winter quarter was canceled, and The Journal reported that he'd postponed the course to the spring. A reading group he was set to lead has also been canceled, according to Stanford's course catalog.

Barbara Fried worked as a professor of law at Stanford until she retired from teaching in September. Her scholarly interests were "at the intersection of law, economics, and philosophy," according to her biography on the university's website.

The New York Times reported that Fried and her husband were popular faculty members at Stanford and regularly hosted dinners for colleagues.

Fried writes short stories and poems. She also penned a biography of the economist and lawyer Robert Hale and worked as a review editor for the journal Philosophy & Public Affairs.

Fried graduated from Harvard University in 1983, per her Stanford biography. Her first job after graduating was as a law clerk to US circuit judge J. Edward Lumbard of the Court of Appeals. She went on to practice as an associate at Paul, Weiss, Rifkind, Wharton & Garrison.

Fried joined Stanford as an assistant professor in 1987 and went on to win multiple awards for excellence in teaching. She also had stints as a visiting professor at New York University Law School, her biography says.

Fried cofounded Mind the Gap, a Democratic super-PAC, from which she resigned in November 2022, The Times reported.

Prior to FTX's collapse, Bankman-Fried was a poster boy for effective altruism, a movement in which followers commit to doing the most good for the largest number of people using science, evidence, and reason.

Will MacAskill, an academic at Oxford University and a central force behind effective altruism, is said to have introduced Bankman-Fried to the movement. However, Bankman-Fried's parents appear to have had some hand in shaping his philosophical outlook.

An article published on the website of Sequoia Capital, the venture capital firm, said Bankman and Fried raised their son on utilitarian beliefs, including family discussions about how to do the greatest good for the largest number of people.

Both have an academic interest in corporate ethics, and his mother has written a review of a book by Peter Singer, seen by many as the originator of the effective altruism movement.

Bankman and Fried aren't named as defendants in the lawsuits filed by US regulators and federal prosecutors against FTX and their son. However, the Securities and Exchange Commission has accused their son of misappropriating FTX customers funds to purchase Bahamian real estate for various people, including his parents.

Reuters reported in November that Bankman and Fried were listed as signatories for a $16.4 million home in a gated community in the Bahamas, which was described in property records as a vacation home.

A spokesperson for Bankman and Fried told Reuters they'd tried to return the property deeds to FTX before the company entered bankruptcy.

Bankman-Fried said last month that he didn't know the details of the property purchase.

Bankman-Fried said at The New York Times DealBook Summit that his parents "bore no responsibility" for FTX's downfall.

"Anyone close to me, including my parents and employees and coworkers, who fought with the company to push forward, they were hurt by this," he said."I feel really grateful for the support my parents are still giving me throughout all of this."
