Leopold Aschenbrenner's $35bn July trading loss on Jane Street Capital has topped the global leaderboard of fund facepalms. The Financial Times used a Wikipedia table of financial disasters to visualize these catastrophic losses, color-coding them by entity type and adding interactive pop-ups with detailed information.

Most of the top 25 losses come from banks and companies, not funds. Only seven are from funds, with Millennium Management needing just a few per cent drop to generate a $2bn loss. The article explains that fund losses require first inspiring confidence with strong ideas and risk management, then abandoning those principles with high-conviction bets and leverage.

Other notable losses include Tiger Global's $40bn bloodbath in 2022 and reported hits to Jane Street and Millennium Management. The author questions whether these leaderboards capture only the most dramatic meltdowns that make good copy, suggesting many significant losses go unrecorded.
