Capgemini is Europe's biggest systems integrator and the world's number two behind Accenture. Its AI bet is the integrator’s bet: it does not build its own frontier models, it rents them, and it wires them into clients. It is aligned with OpenAI through the Frontier Alliance, runs an NVIDIA AI Factory for sovereign on-prem work, and assembles its agentic offering (RAISE) on top of whichever models the client needs.

Its real differentiation is not the model layer but the engineering muscle around it, Intelligent Industry work in manufacturing, automotive and defense, and the European sovereignty angle that plays well with governments wary of US hyperscalers. The $3.3B WNS deal bolted on scaled operations and a test-bed for pricing that is not just billed by the hour.

The catch: it is the lower-margin number two, about 400 basis points below Accenture, growing barely above flat organically, and it discloses no AI revenue at all. It even took an equity stake in the OpenAI deployment company, which is the integrator’s paradox in one move: funding the very lab that could one day disintermediate it, in exchange for roadmap access.

In the price: investors treated the transition as a restructuring burden rather than a breakout, marking the stock down about 36% over the year to roughly €96.72 and near a multi-decade-low multiple.
