7 Servers Worked. The 8th Burned $460M in 45 Minutes.

On August 1, 2012, one forgotten server started sending orders it could never stop. In 45 minutes, Knight Capital lost more than $460 million, more than the entire company was worth. This is the true story of the most expensive software mistake in Wall Street history: a piece of code asleep for seven years, one server nobody checked, 97 warning emails nobody opened, and a fix that made everything worse. Halfway through, we rebuild the bug ourselves in a simulator and watch it happen. ⏱️ CHAPTERS 0:00 This Inbox Cost $460 Million 1:13 One in Ten 2:26 The Ghost 3:53 Seven Out of Eight 5:30 9:30 AM 6:50 The Fix That Made It Worse 8:57 9:58 AM 10:19 The Price of Survival 12:22 Ninety-Seven 📚 SOURCES U.S. SEC, Order Instituting Proceedings against Knight Capital Americas LLC, Release No. 70694 (October 16, 2013) U.S. SEC, Press Release 2013-222: "SEC Charges Knight Capital With Violations of Market Access Rule" Reuters and Bloomberg reporting, August 2012 Some figures are rounded or simplified for storytelling.
