Meta Platforms acquires AI data platform Sundial

The strategic signal here is less about Sundial itself than about where Meta sees AI bottlenecks: data infrastructure, not just models. Bringing an external data platform in-house suggests Meta wants tighter control over how training and operational data are handled, a build-versus-buy choice that other large AI spenders will be judged against. With deal terms and integration plans undisclosed, the practical effects on Sundial's existing customers and partners remain unclear. Whether the acquisition closes cleanly and how quickly Sundial's capabilities surface inside Meta's AI stack is the open question worth tracking.
