AI Holders Summary · Q1 2026

CSX Corp (CIK 126408103, Industrials, $53.6B institutional value, 1,804 holders) closed Q1 2026 with near-universal top-holder buying: nine of the top 15 managers increased, two held, two multi-CDK Vanguard entries are structural artifacts, and only Northern Trust (-$75.6M / -2.1%) and Lazard (-$3.7M / -2.3%) trimmed slightly. BlackRock led buying at $1.42B (+12.6% share increase, existing position already $6.59B), while its existing 160.5M share position grew further. Capital Research Global Investors executed the most aggressive rotation: from $4.2M (4.2M shares) to $807.5M (19.7M shares) — a +$655M / +4.7x expansion, the single highest-conviction signal in this register. JPMorgan added $552M (+53.6%), Viking Global +$266M (+52.6%), Goldman Sachs +$246M (+61.9%), Royal Bank of Canada +$402M (+353%), and Ameriprise +$260M (+49.8%). Bank of America was the largest net-seller at –$42.6M (–9.2%). Aggregate buy volume in the top 20: ~$5.4B; aggregate sell: ~$500M. Net flow: strongly positive. Three Vanguard CIKs reporting as NEW total $6.9B — reporting artifacts, not new capital; actual Vanguard consolidated position is $10B+. The honest read: CSX is experiencing its strongest institutional-near-consensus quarter, with active and passive managers across styles agreeing on railroad-stock resilience in a rate-cut cycle — lower financing costs on long-lived rail assets, potential infrastructure stimulus, and pricing power on a fixed-asset network all serve the bull case.

CSX (a $50B+ market-cap railroad operator, eastern U.S. network) entered 2026 with a strengthened institutional book: 1,804 holders and $53.6B total institutional value — approximately the company's entire public-float valuation, meaning the register captures essentially all shares held by identifiable institutions. The Q1 2026 holder-level data shows a near-universal buy signal that is atypical for any large-cap name.

BlackRock's $1.42B increase is the defining top-holder move.
