Event Summary

U.S. hyperscalers including Microsoft, Alphabet, Amazon, Meta Platforms, and Oracle are investing heavily in AI infrastructure, with capital expenditures expected to exceed free cash flow by 2027. According to a Reuters analysis of London Stock Exchange Group consensus estimates, the companies will generate about $340 billion more in annual operating cash flow in 2027 than in 2025, but capex is expected to rise by roughly $534 billion. Microsoft's AI business has surpassed a $37 billion annual revenue run rate, and Amazon reported 28% growth at AWS. However, Oracle's free cash flow has turned negative, and its shares have lost 36% this year. Investors are concerned about sustained spending and cash depletion, with buybacks potentially at risk if AI monetization takes longer than expected.
