SBF Would Be Worth $126 Billion Today If He Wasn’t Caught — Here’s the Insane Math Behind His AI Bets

Sam Bankman-Fried is sitting in a federal prison serving 25 years. His net worth is officially zero.

But if FTX had never collapsed, his investment portfolio would be worth approximately $126 billion today. That would make him the fourth-richest person on Earth, ahead of Larry Ellison and just behind Jeff Bezos.

The number is not speculation. It is simple math applied to real investments that FTX actually made, at prices that are publicly verifiable today.

Here is how a 30-year-old playing with stolen money accidentally assembled the greatest venture portfolio in history.

The Portfolio That Would Have Changed Everything

Before FTX collapsed in November 2022, the company and its sister trading firm Alameda Research held stakes in several companies that have since exploded in value.

Anthropic: $500 million invested at a $2.5 billion valuation for an 8% stake. That stake would be worth $82.3 billion today at Anthropic’s current valuation. A 165x return.

SpaceX: An indirect stake of approximately $225 million through K5 Global investments. Worth an estimated $15 billion today. A 75x return.

Cursor: Alameda invested $200,000 in Anysphere (the company behind the AI coding tool Cursor) in April 2022, buying roughly 5% of the company at a $4 million valuation. That stake would be worth $3 billion today. A 15,000x return.

Robinhood: FTX held a significant stake worth approximately $4.9 billion at current prices. An 8x return.

Solana: FTX was the largest institutional holder of SOL tokens. Those holdings would be worth $5.1 billion today. A 27x return.

Genesis Digital: Valued at approximately $3.5 billion. A 3x return.

Total estimated portfolio value: $114 billion. Add in FTX’s own exchange revenue and SBF’s personal holdings, and the number climbs to roughly $126 billion.

How SBF Got Into These Deals

The Anthropic investment is the crown jewel of this hypothetical portfolio, and the story of how it happened reveals everything about the world SBF was operating in.

In early 2022, Anthropic was a promising but unproven AI safety startup founded by former OpenAI researchers Dario and Daniela Amodei. They needed serious capital to build computing infrastructure. The AI funding environment in early 2022 was nothing like it is today. Finding an investor willing to write a single $500 million check was extremely difficult.

Enter SBF. He approached the Anthropic team with a pitch that combined two things they cared about: bullishness on AI and concern about AI safety. In Dario Amodei’s own words, SBF at the time appeared to be “bullish on AI and concerned about safety,” which aligned with Anthropic’s mission.

The practical reality was simpler. SBF had $500 million in cash (well, customer funds) and was willing to deploy it in a single check. Alameda led Anthropic’s Series B, investing $500 million out of the total $580 million raised. That one check bought 8% of what would become one of the most valuable AI companies in the world.

The DOJ later alleged that this $500 million came directly from FTX customer deposits. SBF was not investing his own money. He was investing yours.

The Cursor Bet Nobody Talks About

The Cursor investment might be the most painful number in the entire portfolio.

In April 2022, Alameda wrote a check for $200,000 to a tiny startup called Anysphere. At the time, the company had no product, no revenue, and a $4 million valuation. The $200,000 bought roughly 5% of the company.

After FTX collapsed, the bankruptcy estate sold that stake in 2023 for the same $200,000 Alameda had paid. The trustees apparently saw no reason to hold a pre-product AI startup when they needed to liquidate assets to pay back creditors.

Anysphere went on to build Cursor, which became the fastest-growing AI coding tool in the world. That $200,000 stake would be worth $3 billion today.

The bankruptcy trustees sold a $3 billion position for $200,000. A decision that will be studied in business schools for decades.

The SpaceX Connection

FTX’s SpaceX exposure came through K5 Global, a venture fund run by Michael Kives and Bryan Baum that served as a bridge between Hollywood, Silicon Valley, and the crypto world. K5 was one of SBF’s key connectors to deals that a crypto exchange normally would never access.

Through K5, FTX got indirect exposure to SpaceX at a time when SpaceX shares were trading at a fraction of their current value. That indirect stake would be worth approximately $15 billion today.

SBF’s ability to get into these deals was not about investment brilliance. It was about having seemingly unlimited capital and a willingness to write checks that made other investors nervous. When you can casually commit $500 million to a single round, doors open that would normally be closed to a 29-year-old in cargo shorts.

Could He Have Paid Everyone Back?

This is the question that haunts the entire story.

At the time of FTX’s collapse in November 2022, the company owed approximately $8.7 billion to customers. SBF’s hypothetical portfolio is now worth $114 billion. He could have paid back every single customer more than 13 times over and still been worth over $100 billion.

SBF himself has made this argument from prison. His position has always been that if FTX had survived the liquidity crisis — if CZ had not triggered the bank run, if the market had not panicked — the company would have recovered. The investments would have matured. Customers would have been made whole. And nobody would have gone to jail.

There is a version of this argument that is technically plausible. FTX’s bankruptcy estate has actually returned more than customers’ original account balances to creditors, largely by liquidating these same investments (though at much lower prices than today). If the estate had held longer, the returns would have been even larger.

But this argument has a fatal flaw. SBF did not have permission to make these bets with customer money. The returns do not retroactively make the fraud legal. A bank teller who steals from the vault to play poker and wins big still committed robbery.

Why Was He Caught?

SBF was not caught because of a Bitcoin crash. He was caught because of a balance sheet leak and a business rival.

On November 2, 2022, CoinDesk published an investigation revealing that Alameda Research’s balance sheet was loaded with FTT tokens — the house token created by FTX itself. Alameda’s supposed assets were largely backed by a token that FTX controlled, which meant the entire financial foundation was circular and fragile.

Four days later, Binance CEO Changpeng “CZ” Zhao announced he was selling all of Binance’s FTT holdings. This was the match in the gas tank.

Caroline Ellison, CEO of Alameda, made what CZ later called “a fatal mistake” — she publicly offered to buy CZ’s FTT at $22 per token. This accidentally revealed a floor price. Professional traders immediately shorted FTT through that floor. The token crashed from $22 to $5 in 72 hours.

FTX customers panicked. $6 billion in withdrawal requests hit in days. FTX could not honor them because the money was not there. It had been sent to Alameda to cover trading losses and fund venture investments.

Binance briefly agreed to acquire FTX on November 8. One day later, Binance walked away after due diligence revealed “mishandled customer funds.” On November 11, FTX filed for bankruptcy.

CZ recently revealed in his memoir that SBF had casually asked him for a $6 billion bailout before the collapse — a request so audacious that CZ initially thought it was a joke.

What If He Had Kept Going?

The darkest hypothetical is this: if the CoinDesk article had never been published, or if CZ had decided not to dump FTT, SBF might have continued operating for years.

The $8.7 billion hole in customer funds was real but hidden. As long as no one triggered a bank run, the illusion held. And meanwhile, the investments were compounding at extraordinary rates.

Anthropic’s value went from $2.5 billion (when SBF invested) to over $60 billion by late 2024 to over $800 billion in early 2026. At some point between 2024 and 2025, the Anthropic stake alone would have been worth enough to fill the entire customer deficit several times over.

In theory, SBF could have quietly returned the customer funds, closed the hole, and no one would have ever known. He would be a billionaire hero instead of a federal inmate.

But that theory requires believing that a person who had already demonstrated a willingness to commit fraud would have voluntarily stopped. History suggests otherwise. The more likely scenario is that SBF would have used the growing portfolio as collateral to take even bigger risks, creating an even larger disaster when the music finally stopped.

The Bottom Line

Sam Bankman-Fried was not a genius investor. He was a guy with unlimited access to other people’s money who happened to write checks during the most transformative technology shift since the internet.

Anyone with $500 million in 2022 and the willingness to bet big on AI would look like a prophet today. The difference is that legitimate investors used their own capital. SBF used his customers’ savings.

The $126 billion hypothetical is not a story about investment skill. It is a story about what happens when stolen money lands in the right place at the right time. And about the thin line between the world’s greatest investor and a federal prisoner serving 25 years.

SBF’s current net worth: $0.

His hypothetical net worth: $126 billion.

The difference between those two numbers is a CoinDesk article, a CZ tweet, and a $22 floor price that should never have been spoken out loud.
