OECD, “Artificial Intelligence Markets: Recent Developments and Competition Issues”
The OECD finds a mixed competitive picture: foundation-model performance continues to improve while quality-adjusted prices decline and leadership changes hands, but structural concentration persists in the inputs that determine long-term market power, particularly advanced chips, cloud infrastructure, compute, proprietary data, and specialized talent. The report warns that vertical integration, first-mover advantages, and preferential partnerships between model developers and dominant chip or cloud providers could entrench a small group of firms even if the model layer currently appears dynamic.
