# Who owns a public company?

Legally, a public company is owned by its **shareholders** - anyone from an index fund holding 8% to a retail investor holding eight shares. So when people ask "who owns Alaska Air?" or "who owns Zions Bancorporation?", the useful answer is a breakdown: how much belongs to **insiders**, how much to **institutions**, and whether any single holder has real control.

## The three ownership groups

- **Insiders** - directors, executives, and [10%+ beneficial owners](https://insideralpha.ai/learn/what-is-a-10-percent-owner). Their stakes and every trade they make are public via Forms 3, 4, and 5.
- **Institutions** - index funds, mutual funds, pensions, hedge funds. At many large U.S. companies the biggest holders are index-fund managers such as Vanguard, BlackRock, and State Street, each with a stake of several percent: ownership without operational control.
- **Retail and everyone else** - the remaining float.

## Where to look it up (all free)

- **The proxy statement (DEF 14A)** has a "beneficial ownership" table listing every director, officer, and 5%+ holder.
- **Schedules 13D and 13G** are filed when anyone crosses 5%: a 13D when the holder may try to influence the company, a 13G for a passive holding.
- **Form 13F** shows each institution's quarterly holdings.
- **[Form 4](https://insideralpha.ai/learn/sec-form-4)** reports each change in an insider's stake within two business days, with the shares owned afterward. InsiderAlpha lists these filings on every [company page](https://insideralpha.ai/companies); the [ownership percentage guide](https://insideralpha.ai/learn/insider-ownership-percentage) explains how to read them.

## Quick answers to common "who owns" questions

- **Alaska Air** - [Alaska Air Group](https://insideralpha.ai/company/ALK) is a public company (NYSE: ALK); it in turn owns Alaska Airlines and, since 2024, Hawaiian Airlines. No controlling shareholder - its largest holders are institutions.
- **Zions Bancorporation** - public ([Nasdaq: ZION](https://insideralpha.ai/company/ZION)) and mostly held by institutions, with no controlling shareholder.
- **FNF** - [Fidelity National Financial](https://insideralpha.ai/company/FNF) is public (NYSE: FNF) and is not part of Fidelity Investments, a common mix-up. FNF itself majority-owns F&G Annuities & Life.
- **KBR** - [KBR](https://insideralpha.ai/company/KBR) has been an independent public company since Halliburton spun it off in 2007.
- **AAON** - [AAON](https://insideralpha.ai/company/AAON) is public (Nasdaq) and mostly held by institutions.
- **BJ's Wholesale** - [BJ's Wholesale Club Holdings](https://insideralpha.ai/company/BJ) has been public since its 2018 IPO, when its private-equity owners began selling down; today it is mostly held by institutions.

## "Who owns X" vs "what does X own"

The reverse question matters just as often - a listed parent can own many famous brands:

- **[Altria](https://insideralpha.ai/company/MO)** owns Philip Morris USA (Marlboro in the U.S.), U.S. Smokeless Tobacco (Copenhagen, Skoal), John Middleton, NJOY, and stakes in Anheuser-Busch InBev and Cronos Group (about 41% of Cronos).
- **[Royal Caribbean Group](https://insideralpha.ai/company/RCL)** owns Royal Caribbean International, Celebrity Cruises, and Silversea, plus half of TUI Cruises and Hapag-Lloyd Cruises.

When a brand you searched for turns out to be a subsidiary, the insider filings and the stock you can buy belong to the parent.

## Holdings versus trades

An ownership table tells you who held the stock on the date it was prepared. [Insider trades](https://insideralpha.ai/learn/insider-buying-signals) tell you which owners have been adding or cutting since. Purchases by the people who run the company get the closest reading of all, because they are putting their own cash into a business they see from the inside.
