Alphabet Lost About $482B in Its Worst Day Since Listing in 2004
Alphabet Class A shares fell 12.6% to $283.82 on 29 Oct 2026, their worst session since trading began in 2004, beating the −11.6% of March 2020. About $482B of market value was wiped out, by Yahoo Finance calculations from Bloomberg data, the second-biggest one-day loss for a US-listed company after Nvidia's roughly $593B on 27 Jan 2025; CNBC put it near $500B. The trigger was Q3 search and other revenue growth of 12% to $63.35B against about 15% expected.
