Welcome to the rare Monday drop of a preview from Stealing the Future, my forthcoming book. I’m experimenting with the timing of the newsletter - I’ve always assumed Sunday was when people were most likely to sit around reading long-form essays, but let’s find out! On a similar note, keep an eye out this week for a reader survey as part of the weekly news roundup. With the book drawing bit by bit to a close, my focus will be shifting back towards growing Dark Markets, and that entails learning more about who my readers are, and what they want.

In the meantime, enjoy this meditation on trading, speculation … and witchcraft.

Though he didn’t know much about crypto at first, he discovered that trading it could be particularly lucrative, largely thanks to inefficiencies of the then-nascent market. And so he launched his next venture - the trading firm Alameda Research.

This is also the dynamic of the trader’s life: symbols of certainty and control constantly ringed around by the terrifying unknown. Operating in this semi-occlusion is one of the most important skills of a trader, the ability to make a decision based on half-knowledge or intuition.

In 2020, Bankman-Fried reflected on the motivation for the shift: β€œIf I really think I should be trying to maximize expected values, then that implies substantially riskier strategies than what seems intuitively right.” He was by this time earning more than a million dollars a year as a trader at Jane Street (despite losing the firm $300 million), but he wanted more.
