About Daniel Sundheim

Daniel Sundheim, formerly CIO of Viking Global, founded D1 Capital to run a hybrid public-private book, quickly becoming one of the highest-profile launches of its generation — and one of the most tested during 2021's meme-stock short squeeze and the 2022 growth drawdown.

D1's 13F shows a concentrated public sleeve in internet platforms, travel, and financial infrastructure, sitting beside a large private portfolio the filing doesn't capture.

Methodology: turnover is min(value bought, value sold) ÷ average reported value across the two quarters — value-based, so market moves inflate it slightly versus a share-based measure. Concentration and largest position are shares of the filing’s total reported value, options excluded. New/exited counts compare against the prior filed quarter. All figures derive solely from the fund’s 13F filings.
