3M CO
2,303 institutions still hold 3M CO as of Q1 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
MMM Q1 2026 institutional ownership is a $53.6B book across 2,052 holders. Every reported position is classified NEW, indicating the prior-quarter comparison dataset is unavailable. MMM underwent Medtronic separation in 2025/2026 -- book discontinuities are structural rather than genuine one-quarter total turnover. JPMorgan is reported at $6.6B (46.4M shares, NEW), which is consistent with a post-separation re-statement. BlackRock $6.2B (42.7M shares, NEW). Vanguard Capital Management $5.0B (34.2M shares, NEW); Vanguard Portfolio Management $1.4B (9.5M shares, NEW). State Street $4.0B (27.7M shares, NEW). Geode Capital $1.7B (11.9M shares, NEW). FMR LLC $1.4B (9.5M shares, NEW). Capital World Investors $1.3B (9.2M shares, NEW). State Farm $1.2B (7.9M shares, NEW). Morgan Stanley $1.1B (7.5M shares, NEW). Northern Trust $817M (5.6M shares, NEW). Newport Trust $812M (5.6M shares, NEW). Bank of America $793M (5.5M shares, NEW). Goldman Sachs $786M (5.4M shares, NEW). UBS AM $532M (3.7M shares, NEW). UBS Group $616M (4.2M shares, NEW). Charles Schwab IM $498M (3.4M shares, NEW). Janus Henderson $493M (3.4M shares, NEW). Legal & General $478M (3.3M shares, NEW). Invesco $611M (4.2M shares, NEW). New positions: entire reported book. The 75.50 whaleScore reflects AUM. Smart-money read: snapshot only. MMM institutional book is $53.6B across 2,052 holders. JPMorgan $6.6B and BlackRock $6.2B are the #1 and #2 holders post-Medtronic separation -- this is a significant structural shift. Without prior-quarter comparison, directional read is neutral. Post-separation name reconstruction (3M spin-off completed Sep 2024, Medtronic thoraco separate) means the institutional holder mix shifted substantially -- many positions that looked "NEW" in Q1 2026 filings may have migrated from legacy 3M holdings. MMM's institutional IOV has contracted marginally vs. pre-separation levels, but the $53.6B book remains large for a diversified industrials/healthcare name. Read: neutral snapshot, no directional signal until prior-quarter data is available for comparison.
