Nvidia loses $1 trillion amid CEO scandal, wiping out value equal to all of Brazil's B3

Nvidia lost US$1.081 trillion (about R$6.1 trillion) in market value between October 29 and November 10, 2026, amid a scandal involving CEO Jensen Huang, according to a survey by Elos Ayta. The drop exceeds the total market value of all companies listed on Brazil's B3 stock exchange by over R$1 trillion. The company's market value fell from US$5.149 trillion to US$4.068 trillion, a reduction of approximately 21% in just eight trading sessions. The losses were triggered by repercussions of an alleged marital infidelity by Huang and suspected Chinese espionage, raising concerns about information security, though Nvidia says it has no evidence its corporate secrets were compromised. For comparison, the loss equals about 1.22 times the total value of all B3-listed companies and nearly ten times Petrobras's market value. The decline in just the last two sessions, US$430 billion, represents roughly 96% of the combined value of Brazil's three most valuable sectors: banks, oil, and electric energy.
