Dan Sundheim - The Art of Public and Private Market Investing - [Invest Like the Best, EP.460]

My guest today is Dan Sundheim. Dan is the founder and CIO of D1 Capital Partners. He thinks about markets and businesses constantly, and has built a career entirely around that obsession. He manages over $30B across both public and private markets, with investments in SpaceX, OpenAI and Anthropic, and a public portfolio of names you may never have heard of. Dan shares the story of the short case he wrote on Orthodontic Centers of America and posted on Value Investors Club, which crashed the stock, and helped him land his first job. He shares why he backed Anthropic at a moment when many people told him it was the Lyft to OpenAI’s Uber, what reading Dario Amodei’s essays reminded him of Jeff Bezos, and how he thinks about LLM business models through the lens of Netflix and Spotify. We spend time on the extraordinarily stressful moment in early 2021 when GameStop hit the firm, and what Dan believes is the single biggest tail risk facing the global economy right now.
