IBMInternational Business Machines Corporation
Diversified incumbent, not a quantum pure-play - but the most credible Western superconducting-qubit program (Qiskit, Heron/Condor roadmap) and now the policy-backed national champion: >$10B five-year commitment plus a US Commerce Dept LOI (~$1B grant + a minority federal equity stake) co-funding the Anderon 300mm quantum foundry in Albany, fault-tolerance targeted 2029. Quantum is a sub-1%-of-revenue option today; the bubble placement reflects narrative / co-movement (the May-2026 re-rating was quantum-policy-driven), not revenue mix.
