Why EQIX is in the WallStreet AI Index
Interconnection + data centers that host the AI cloud's private infrastructure.
Its role in the AI value chain
Equinix Inc. belongs to the Data & Infrastructure layer of the AI economy. The foundation layer: the databases, data platforms, colocation/data-center real estate, integrators, and device ecosystems that AI workloads actually run on.
The WallStreet AI Index is built to capture the entire AI value chain rather than a single hot sub-sector, so a name like EQIX is weighted for its contribution to the AI stack, not just its headline market cap. A per-name cap of 8% keeps any single mega-cap from dominating the index, which means EQIX's inclusion is about the role it plays in enabling AI, not merely its size.
How EQIX is weighted
WallStreet AI Index uses a segment-balanced, capped, price-return methodology. Each of the index's six segments receives a target weight; constituents are weighted within their segment; and an 8% per-name cap is applied and redistributed. On that basis, Equinix Inc. represents roughly 1.33% of the index. You can see its live contribution to the index each day on the index dashboard.
