The AI angle
Carlyle has discussed AI in the context of its private-equity and technology investments but does not run a prominent public AI-infrastructure program like Blackstone or Apollo. For AI strategists, Carlyle's relevance is in how it allocates capital across the software and enterprise-technology portfolio that sits at the heart of the AI economy.
