Bain says the global AI industry must reach roughly $6 tln in annual revenue by
2031 to justify current large‑scale capital spending on global data centers. Its
annual global tech report issued Tuesday estimates consumer and enterprise AI
services will contribute at most $1.8 tln, leaving an approximate $4.2 tln gap
that would need to be filled by automation and robotics and new applications
such as drug R&D, mental health and energy production. Bain's global TMT head
and lead author David Crawford warned AI infrastructure build‑out is outpacing
demand growth; sustainable financing would likely require global GDP growth
about 1 percentage point higher than otherwise.
