Tech companies are spending hundreds of billions annually on AI infrastructure while revenues remain a fraction of those outlays, raising urgent questions about the sustainability and profitability of the AI boom. The Financial Times' running tally of hyperscaler capex shows Amazon, Microsoft, Alphabet, and Meta collectively planning approximately $725 billion in capital expenditure for 2026, a 77% increase from roughly $410 billion in 2025.
