Alphabet's tree has one giant trunk — Google — a portfolio of Other Bets, and only three legal subsidiaries it calls significant

Asked:

“What is alphabet's corporate hierarchy structure? name all the companies in the hierarchy tree”

This map covers 25 nodes assembled from Alphabet’s official 2025 Form 10-K and Exhibit 21 plus public company lists, scanned 2026-09-02: 23 currently in Alphabet’s controlled tree and 2 former companies shown separately. Alphabet reports Google through two segments — Google Services and Google Cloud — plus Other Bets; its SEC filing names just three significant legal subsidiaries and expressly omits the rest, so no public source gives an exhaustive worldwide entity list.

holding company Google side: operating company or subsidiary reportable segment / grouping — not a company Other Bets operating company Alphabet investment business no longer controlled (shown apart)

Two official views that overlap but are not the same

Reporting view — Form 10-K segments

Alphabet describes itself as “a collection of businesses — the largest of which is Google”, reports Google in two segments, Google Services and Google Cloud, and all non-Google businesses collectively as Other Bets. These segments are groupings for reporting, not incorporated companies. sec.gov

Legal view — official significant subsidiaries (Exhibit 21)

As of 2025-12-31 Alphabet names only three significant legal subsidiaries, all Delaware entities, and states that insignificant subsidiaries are omitted. The filing does not disclose their downstream children.

Google LLC — Delaware
XXVI Holdings Inc. — Delaware
Alphabet Capital US LLC — Delaware

Not in the controlled tree now

Verily (precision health) and Mineral (agriculture AI) are no longer Alphabet-controlled companies; they appear here only to correct stale hierarchy lists, not as children of Alphabet. beri.net

Alphabet’s 10-K reports Google in exactly two segments — Google Services and Google Cloud — with everything non-Google grouped as Other Bets. sec.gov

Only 3 legal subsidiaries — Google LLC, XXVI Holdings Inc. and Alphabet Capital US LLC — are named as significant; the filing explicitly omits insignificant ones, so the operating layer here is a best public-facing map, not a definitive legal ownership chain. sec.gov

The 2026 picture is moving: Wiz closed into Google Cloud in March 2026, Intrinsic was merged into Google, and Alphabet sold down GFiber to a minority stake. industrytap.com

Verily and Mineral left Alphabet’s control and appear in many stale “Alphabet companies” lists; they are shown apart here, not as children of Alphabet. beri.net

Corporate hierarchy map of Alphabet Inc., 25 rows scanned 2026-09-02: 23 currently-controlled nodes plus Verily and Mineral, no longer controlled. Backbone from Alphabet’s 2025 Form 10-K and Exhibit 21 (as of 2025-12-31); operating-company placements from public company lists and may differ across secondary sources during 2026 reorganizations. Alphabet omits insignificant subsidiaries, so this is not an exhaustive legal-entity list. Evidence quotes trimmed for space.
