✦ Cloud, TPUs & AI InfrastructureNarrow moat

Alphabet (Google) (GOOGL) — the future bets

The TPU turned Google's third-place cloud into the only store selling a proven alternative to Nvidia — and Anthropic just ordered a million of them.

Google Cloud spent a decade as the also-ran — a distant third behind AWS and Azure, roughly an eighth of the market by the share trackers3 — and then the AI cycle handed it the one card the leaders do not hold. Revenue growth accelerated to 103 percent while the backlog swelled to $561 billion1, the fastest growth of any hyperscaler by a wide margin.

Growth went from 28% to 103% in six quarters - the acceleration the backlog had been promising.

The card is the TPU. Google has designed its own AI silicon since 2015, and for years that read as an internal cost saving. In October 2025 it became a product: Anthropic contracted for up to one million TPUs and more than a gigawatt of capacity, a deal worth tens of billions2 — the first proof that a frontier lab will bet its training runs on non-Nvidia silicon at scale. Gemini itself trains on TPUs; the sales pitch is simply Google's own infrastructure, rented out.

The honest caveats: an eighth of the market is still an eighth, AWS and Azure hold the enterprise relationships, and every hyperscaler now builds custom chips — the TPU's edge is a head start, not a patent. But a third-place cloud growing at twice the leaders' pace, holding half a trillion in contracted work and the only proven Nvidia alternative an outsider can buy, is a different asset than the one the market filed away years ago. Watch the backlog: it nearly doubled in three months, and it converts to revenue on a schedule.

Moat trajectory: Widening

Widening from third place: 103% growth is the fastest of any hyperscaler, the backlog reached $561 billion with just over 55% of it due to convert inside two years, and the Anthropic TPU deal proved outside frontier labs will build on Google silicon at scale. The gap to AWS and Azure is still large, and closing.

The number that tests this moat
Reported
Cloud backlog, and the share with a date on it
$561B, just over 55% within 24 months

The backlog grew from $514 billion a quarter earlier, and for the first time management said how fast it converts: just over 55% is expected to become revenue within twenty-four months. That turns a headline number into a schedule. Watch both halves - a backlog that keeps growing while the 24-month share falls is a promise being pushed further out.
