Dassault Plunges by Record in Latest Selloff Over AI Fears

Dassault Systemes SE shares plunged by the most ever after issuing weak guidance, stoking concerns that artificial intelligence will disrupt its business model and turning the stock into one of the biggest targets yet of a fear-driven selloff in businesses viewed as vulnerable to AI.

Sales will grow 3% to 5% in 2026, Dassault said in a statement Wednesday. That compared to an average 5.9% estimate from analysts in a Bloomberg survey. The company blamed stumbling sales on an anemic automotive sector and shrinking business at its life sciences division.
