Musk: Only OpenAI, Anthropic and SpaceX’s Cursor Have Enough Coding Data for Top AI

Musk's framing matters less as a scorecard than as a claim about data scarcity: coding corpora, not compute or capital, are being cast as the binding constraint on frontier model quality. That logic cuts against the wave of cloud and chip commitments in the same roundup, since those deals scale capacity rather than proprietary training data. The open question is whether data-access arguments gain traction with regulators and customers, or remain a rhetorical edge for incumbents.
