Chinese competitors are now matching Western AI capabilities at a fraction of the cost, validating the low-moat thesis that has haunted the sector since 2023. Foundation models lack defensible advantages once the base technology diffuses globally. This isn't margin compression alone; it's structural. If performance parity is achievable by well-funded teams outside the U.S., the venture capital narrative around "winner-take-most" AI platforms weakens. Valuations across every downstream application layer face recalibration. The question is no longer whether China catches up, but whether American AI companies can find defensible positions beyond raw inference speed and scale—a much harder problem than simply being first.
