MU institutional ownership: what the Q2 2026 13F filings show
2 of the 59 funds tracked here hold Micron Technology Inc (MU) at 5% or more of their reported 13F portfolio. The largest weighting belongs to Appaloosa (15.06%), followed by Coatue Management (7.46%). A 5% position is a deliberate one: at that size MU is among the handful of names that decide how the fund's quarter goes.
On the buying side, 4 tracked funds increased their MU position in Q2 2026. Ranked by the size of the position they now report, the list is led by Coatue Management ($3.63 bn), Marshall Wace ($1.56 bn) and Sands Capital ($608 m). Sands Capital and Altimeter Capital reported it as new positions, with no MU in the previous filing. On the selling side, 8 funds cut their position, led by Appaloosa ($1.13 bn), D. E. Shaw ($887 m) and Citadel Advisors ($693 m). The dollar figures are the positions as reported at quarter end, not the amounts bought or sold — a 13F gives share counts on two dates, not the trades in between. Each list stops at 10 funds, so a count of 10 means 10 or more.
Among the funds with a page of their own on this site, Coatue Management (7.46%) and Marshall Wace (1.31%) report MU as one of their ten largest positions; the percentage is the share of that fund's reported portfolio. Each fund's page shows what else it holds alongside MU.
MU 13F: questions and answers
Which hedge funds own MU?
Among the 59 funds tracked here, those holding MU at 5% or more of their portfolio in Q2 2026 are Appaloosa (15.06%) and Coatue Management (7.46%). Funds holding it as a smaller position are not in that list, so this is the high-conviction end of the ownership, not the full shareholder register.
Which funds bought MU in Q2 2026?
Coatue Management, Marshall Wace, Sands Capital (new position) and Altimeter Capital (new position). “Bought” here means the share count in the Q2 2026 filing is higher than in the one before.
Which funds sold MU in Q2 2026?
Appaloosa, D. E. Shaw, Citadel Advisors, Two Sigma Investments, Tudor Investment, Point72, Renaissance Technologies and Bridgewater Associates. All of them still report a MU position at the end of Q2 2026, with a lower share count than in the filing before.
How current is this MU 13F data?
It reflects positions on 2026-06-30, the end of Q2 2026. Managers have 45 days after quarter end to file, so the holdings shown are always between six weeks and four and a half months old; filings for the quarter ending 2026-09-30 are due by 2026-11-14. The page is rebuilt daily, so a late or amended filing is picked up when it reaches the SEC.
Is this every institution that holds MU?
No. It covers the 59 funds tracked on this site, and within those only positions of 5% or more in the holders table and the 10 largest moves on each side. Index funds, pension plans and thousands of other 13F filers hold MU too; a fund with a position between 0.5% and 5% of its portfolio appears in the adds and trims only if it changed its share count.

It is neither the total number of institutions holding the stock nor every fund we track that holds it — smaller positions, down to the 0.5% reporting floor, do not appear here. 13F carries up to a 45-day reporting delay and options are excluded. Values are as reported in the filing, not current market value. Insiders are counted, never named. The company name is EDGAR's own spelling.
