The Global Ledger of Market Meltdowns: Who Lost the Most

A Financial Times Alphaville piece visualizes a global leaderboard of the biggest trading losses, led by Leopold Aschenbrenner’s $35bn July hit at Jane Street, and notes that most top losses come from banks or large firms rather than pure funds. It discusses how overconfidence, leverage, and risk-management failures drive these meltdowns and cites famous episodes like Tiger Global’s 2022 downturn and Archegos-style collapses as prominent examples.
