WILLIAMS COS INC (WMB)
Institutional ownership reported to the SEC as of Q2 2026, across 32 quarters.
Institutions report 1,099,102,749 shares against 1,223,167,472 outstanding. Shares only - option lines are excluded, which is why this can be compared with the company at all. The count comes from the cover page of the company's own most recent report, so it is dated when that was filed rather than at quarter end. A figure this high can overstate: where an adviser and a sub-adviser both report the same shares, both are counted.
Calls and puts are the parts of reported value carried in derivative lines rather than shares, and they point in opposite directions: a manager holding calls is positioned for the security, one holding puts against it - or hedging shares they already own, which is why index funds carry so many. Most sites add the two together and report one figure, which averages away the only interesting part.

Q2 2026 in brief
In Q2 2026, 1,848 managers that file Form 13F reported holding Williams Cos Inc (WMB), $84.3B in all, or about 90% of the shares outstanding. 159 managers opened a position and 145 sold out completely, against 1,834 holders the quarter before. Largest holders: Blackrock, Inc., Vanguard Capital Management Llc and State Street Corp. Largest new positions: 1832 Asset Management L.P. ($557.5M), Massachusetts Financial Services Co /Ma/ ($354.2M) and Ontario Teachers Pension Plan Board ($329.1M).
Q2 2026 is the latest quarter whose 13F deadline has passed. A 13F shows long US stock positions at quarter end, filed up to 45 days later; an adviser and a sub-adviser can both report the same shares.
What the company announced
Form 8-K filings from the last 120 days, showing only the items worth a reader's attention. Earnings releases, exhibit attachments and general disclosures are filed constantly and are left out. Filed is when the SEC received it; event is the date the company says the thing happened.
| Filed | Event date | What | Source |
|---|---|---|---|
| 2026-09-10 | 2026-09-10 | Material agreement entered | filing |
| 2026-08-21 | 2026-08-21 | Directors or officers departed or appointed | filing |
What the insiders did
Open market purchases and sales reported on Form 4 in the last 180 days. Grants, option exercises and shares surrendered to cover tax are left out: they are compensation rather than a decision to buy or sell. Where a broker filled one order in tranches the lines are summed, because it was one decision.
