How Sam Bankman-Fried’s FTX-Alameda empire vanished overnight

The Kimchi Swap put Sam Bankman-Fried on the map.

The year was 2017, and the ex-Jane Street Capital quant trader noticed something funny when he looked at the page on CoinMarketCap.com listing the price of bitcoin on exchanges around the world. Today, that price is pretty much uniform across the exchanges, but back then, Bankman-Fried previously told CNBC that he would sometimes see a 60% difference in the value of the coin. His immediate instinct, he says, was to get in on the arbitrage trade — buying bitcoin on one exchange, selling it back on another exchange, and then earning a profit equivalent to the price spread.

“That’s the lowest hanging fruit,” Bankman-Fried said in September.

The arbitrage opportunity was especially compelling in South Korea, where the exchange-listed price of bitcoin was significantly more than in other countries. It was dubbed the Kimchi Premium – a reference to the traditional Korean side dish of salted and fermented cabbage.

After a month of personally dabbling in the market, Bankman-Fried launched his own trading house, Alameda Research (named after his hometown of Alameda, California, near San Francisco), to scale the opportunity and work on it full-time. Bankman-Fried said in an interview in September that the firm sometimes made as much as a million dollars a day.

Part of why SBF, as he’s also called, earned street cred for carrying out a relatively straightforward trading strategy had to do with the fact that it wasn’t the easiest thing to execute on crypto rails five years ago. Bitcoin arbitrage involved setting up connections to each one of the trading platforms, as well as building out other complicated infrastructure to abstract away a lot of the operational aspects of making the trade. Bankman-Fried’s Alameda became very good at that and the money rolled in.

From there, the SBF empire ballooned.

Alameda’s success spurred the launch of crypto exchange FTX in the spring of 2019. FTX’s success begat a $2 billion venture fund that seeded other crypto firms. Bankman-Fried’s personal wealth grew to over $16 billion at its peak in March.

Bankman-Fried was suddenly the poster boy for crypto everywhere, and the FTX logo adorned everything from Formula 1 race cars to a Miami basketball arena. The 30-year-old went on an endless press tour, bragged about having a balance sheet that could one day buy Goldman Sachs, and became a fixture in Washington, where he was one of the Democratic party’s top donors, promising to sink $1 billion into U.S. political races (before later backtracking).

It was all a mirage.

As crypto prices tanked this year, Bankman-Fried bragged that he and his enterprise were immune. But in fact, the sector-wide wipeout hit his operation quite hard. Alameda borrowed money to invest in failing digital asset firms this…
