Institutional ownership

Held by 4 of the superinvestors we track (plus 6 quant / multi-strat books), based on each investor’s most recent 13F (latest Q1 2026).

From quarterly Form 13F filings, which can be up to 45 days delayed. Long US-listed positions only: excludes short positions, options, cash, bonds, and non-US holdings, so this is not a manager’s complete portfolio. Counts are of the investors we track, not all institutions. Not investment advice.
