CSIS reports that by September 2026, leading academics declared the AI performance gap between US and Chinese models effectively closed.

For a financial institution, this structural narrowing challenges the competitive moat of US frontier model vendors and suggests AI leadership may shift toward lower-cost open ecosystems.
