Holder counts are more reliable. Implied quarter-end price ≈ $441.29. Options: 8 managers hold calls ($29.1m notional), 7 hold puts ($19.5m).

Major shareholders (over 5%)
Anyone who owns more than 5% of a class of the company's shares has to say so: on Schedule 13D if they may try to influence or control the company, on 13G if they're a passive investor, and update it as the stake changes. Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
