Alphabet Inc.

Alphabet Inc. is an American multinational technology conglomerate whose largest subsidiary, Google, operates the world's dominant search engine alongside businesses in digital advertising, cloud computing, artificial intelligence, and consumer subscription services, generating $402.8 billion in revenue in fiscal 2025. Through its "Other Bets" portfolio — most notably autonomous vehicle unit Waymo, now providing over 500,000 paid rides per week across 11 U.S. cities — Alphabet funds a collection of ventures that collectively lose several billion dollars a year but carry option value a pure-play search company could not replicate.

This is a story about an extraordinarily profitable advertising franchise funding what may be the most ambitious capital cycle in corporate history. Alphabet's core search business generated roughly $225 billion in Search & Other advertising revenue alone in FY2025, every dollar of which — and then some — is being redeployed into AI infrastructure at a pace that stunned even optimistic observers: $91 billion in CapEx in FY2025, guided to $180–190 billion in 2026, with management explicitly promising a "significant increase" in 2027. In June 2026, the company announced an $80 billion equity raise — the largest in its history — consisting of a $30 billion public offering, a $40 billion at-the-market program, and a $10 billion private placement to Berkshire Hathaway, reversing a decade-long buyback strategy that had retired roughly 13% of shares outstanding since 2016.

The file turns on a single question: whether the AI demand that justifies this investment is durable enough to outlast the depreciation cycle it creates. If it is, Alphabet is building an infrastructure moat that competitors will struggle to replicate. If it is not, the company will have turned a pristine capital-return story into an industrial-scale impairment. The answer is unknowable today, which makes this one of the more consequential judgment calls in large-cap technology.
