Big Tech's AI Spending Pledges Hit $3T, Up From $2.4T in July, With Alphabet Leading at $1T+

Bloomberg's tally of Q3 10-Qs puts Alphabet, Meta, Microsoft, Amazon and Oracle's cumulative AI-related commitments above $3T, up from about $2.4T for four of the five in July. Alphabet alone discloses $1T+ (nearly 8x a year ago), with Meta above $800B. Future leases run $1.3T (some for 30 years) and other orders $1.9T, spanning data centers, equipment, energy and content. Gartner warned 'much of this spending may never pay off' as free cash flow turns negative at some of the firms.
