United States
Founded

Occidental Petroleum is an American oil and gas company headquartered in Houston, Texas, founded in Los Angeles in 1920 and listed on the New York Stock Exchange under the ticker OXY. It explores for and produces crude oil and natural gas, with its largest position in the Permian Basin of west Texas and New Mexico, where it is the biggest operator, alongside operations elsewhere in the United States and production sharing arrangements in the Middle East and North Africa. It also runs midstream and power assets and an enhanced oil recovery business that reinjects carbon dioxide into mature fields. A separate carbon innovation arm pursues direct air capture and carbon management, built up through the purchases of Carbon Engineering in 2023 and Holocene in 2025. The company roughly doubled its size in August 2019 by acquiring Anadarko Petroleum for about 57 billion dollars.

Source

Occidental Pete Corp files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from About Occidental (Oxy) and Occidental Petroleum (Wikipedia). The ownership figures below come from the holders' filings instead, and are sourced row by row.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. Many other shareholders can hold Occidental Pete Corp without appearing here, and nothing on this page rules them out, because this page is only the disclosing holders' side. Percentages are of Occidental Pete Corp where a holder stated one, and are missing where no holder did.
