TL;DR

Microsoft, Meta, Alphabet, Apple and Amazon all reported to Wall Street this week, and all confirmed they intend to keep spending heavily on AI. Collective commitments now exceed $1tn (roughly £743bn). Investors responded by asking, with more force than before, what any of it has produced.

The starkest number came from Alphabet, which spent so much that free cash flow turned negative against $118bn of revenue — the first time that has happened since it went public. Meta was barely better, with $784m of free cash on $61bn of revenue, and its Reality Labs unit lost close to $9bn across the first six months. Neither company’s consumer AI products are generating meaningful revenue against what they cost to build.

Investors are no longer accepting deferred payoffs as an answer. Meta’s shares dropped to their second-lowest point in twelve months after Mark Zuckerberg described an AI agent and a business-facing AI product, neither of which exists yet and neither of which came with a date. Meta simultaneously raised the floor on its spending plans, likely exceeding $140bn this year.

The contrast was the story. Microsoft, planning to roughly match the $190bn it has spent over twelve months, rose to a six-month high on strong revenue and take-up of its main AI product — Forrester’s Tracy Woo said its investments were starting to deliver returns. Amazon, even with cash flow negative and $220bn of planned AI spending, hit a two-month high because its other businesses are working.

That is a market beginning to price execution rather than ambition, which is a healthier position than the one it held six months ago. Demand for the underlying products is genuine: Google says 950 million people use Gemini monthly, triple a year ago, and Apple reported Macs, iPhones and iPads outselling its own forecasts — warning of a slowdown only because it cannot source enough chips.

For UK businesses, the read-across is about supply and pricing rather than share prices. Chip scarcity severe enough to cap Apple’s sales sits upstream of every cloud contract, and hyperscalers under pressure to show returns are the ones setting enterprise AI rates.

Looking Forward

Apple will charge for heavier use of its rebuilt Siri, a decision Tim Cook, who is stepping down as chief executive, attributed to user testing. That is a straw in the wind: consumer AI is drifting towards paid tiers because advertising and bundling have not covered the cost. Expect the same logic to reach business tools.
