  • How many superinvestors hold CMCSA?

  • How much CMCSA stock do superinvestors hold?

    Superinvestors tracked by InsiderSet disclosed approximately $3.98B in CMCSA holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value, and it covers the curated superinvestors on this page rather than every institutional filer.

  • When were CMCSA superinvestor holdings last updated?

    The latest CMCSA superinvestor holdings on InsiderSet are based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time holdings.
