# Paris Stock Exchange shaken by artificial intelligence concerns > Early November 2026, the Paris Stock Exchange fell, penalized by the technology sector, while debates opened on a possible bursting of the artificial intelligence bubble. On November 6, the CAC 40 plunged and investors questioned the timetable, cost and financing of AI's future. On November 9, the Paris market rebounded and closed up more than 1%, driven notably by STMicroelectronics and Airbus. On November 12 and 13, the CAC 40 resisted Nvidia's fall on Wall Street but remained held back by rising oil, doubts about AI and the departure of Nvidia's CEO. The week ultimately ended with a 2.8% gain for the CAC 40, without a down session. **In brief**: Ongoing story bringing together 14 events nationwide, followed from 3 November 2026 to 13 November 2026. 21 articles from 4 sources (economy); last updated on 13 November 2026 at 17:58. -
