Amidst the biggest scandal in the crypto world, there’s an overlooked story: Sam Bankman-Fried’s $500 million investment in an AI company via Alameda Research, which he once controlled. That investment could now be worth $30 billion. The story begins elsewhere.

In the mid-2010s, there was a group of people in San Francisco. They lived in the same neighborhoods and aligned around the same philosophy: Effective Altruism—EA. The core idea was simple—every dollar should, in a mathematical sense, go toward the greatest good. Names like Dario Amodei, Holden Karnofsky, and Paul Christiano circulated in this circle. They were all part of the same social network. SBF was connected to it too, but he embraced a more radical version: win and donate. He moved from Wall Street to the crypto world and said his goal was altruism.

Anthropic’s mission—develop safe AI—was almost the standard solution in EA. In May 2021, Jaan Tallinn launched Series A with $124 million. In April 2022, SBF stepped in. He wrote a $500 million check for Series B funding. He had accounted for 86% of the entire series in that one time. Alameda Research CEO Caroline Ellison and Nishad Singh, FTX’s engineering director, also took part.

But Dario Amodei was extremely careful. In a later interview, he said he saw “enough red flags.” He took the money but gave SBF non-voting shares and kept him out of the board. There was a strange contradiction: if the danger signals were so numerous that they required isolation at the governance level, why was the money still taken? The answer lies in the logic of the EA world. The “cleanliness” of capital is never the priority—only “effectiveness” matters. It isn’t about what will happen; it’s about how well it can be done.

Everything collapsed in November 2022. CoinDesk disclosed Alameda’s balance sheet, and FTX fell apart within nine days. SBF was arrested, tried, and sentenced to 25 years in prison. That $500 million—FTX customers’ deposits—vanished. Anthropic shares were frozen.

In March 2024, a liquidation auction began. Mubadala invested $500 million—exactly the same amount SBF had put in years earlier. The second-largest buyer was Jane Street, SBF’s former employer. In total, $1.34 billion was recovered. The money was paid to FTX creditors, and affected users got back part of their investments.

In February 2026, Anthropic completed a $30 billion funding round in its G round. The valuation reached $380 billion. Without accounting for dilution, that 8% stake could theoretically be worth $30 billion. But the liquidity team sold, because their job was to pay debtors. The disparity is striking—$1.34 billion against potential $30 billion.

In prison, SBF is currently set to remain until 2049, when he will be released at age 57. During that time, the AI company he invested in with dirty money drew the Pentagon’s attention, and its founder became a frequent guest on Times and Congress. If everything had been legal, this $500 million bet could have made SBF one of the most successful venture capital investors.

The truth is this: Dario and SBF grew up on the same ground, joined the same parties, embraced the same philosophy. But one reached a $380 billion AI empire, while the other landed in federal prison. The $500 million check that connected them remains one of the strangest pages in Anthropic’s history. In the crypto world, this story is still being talked about.
