Even muli-billionaires often don't have a direct controlling interest. Sometimes have special shares that give them 10x votes like Larry and Sergey. Bezos, Zuck, and Musk have significant direct amounts of their companies.

The list almost always reads the same on every major corporation. Vanguard, Blackrock, State Street, ect... Numbers may be slightly out of date in some cases. If the Institutionals all vote together or collectively, almost none of the wealthy have "controlling amounts". (wikipedia listings)

  - NVIDIA: The Vanguard Group(8.280%), BlackRock(5.623%), Fidelity Investments(5.161%), State Street Corporation(3.711%), *Jensen Huang(3.507%)*, Geode Capital Management(2.024%), T. Rowe Price(2.013%), JPMorgan Chase(1.417%)

  - Tesla: *Elon Musk(12.9%)*, The Vanguard Group(7.2%), BlackRock(4.5%), State Street Corporation(3.4%), Geode Capital Management(1.7%), Capital Research & Management(1.3%)

Basically, it usually reads like "if Vanguard, Blackrock, and State Street agree on anything, you lose the vote." Alphabet being somewhat exception because of the 10x special votes. Everything listed has more than $1,400,000,000,000 share cost outstanding. Even $100,000,000,000 won't buy enough.

Notably, in-practice they probably usually just vote whatever one of the main founders, CEO's, ect... recommends unless there's some actual major issue. Although that's so far above my pay grade, no idea what actually goes on.

Funnily, the next one on the list is JPMorgan and they're controlled by ... Vanguard, Blackrock, State Street... Who in turn control major portions of NVIDIA, Apple, Amazon, Meta... It's all rather incestuous and circular.

And funnier, they all own each other.

  Vanguard itself is weird, like a mutual fund, and owned by its funds, then in turned owned by shareholders.  However, *those* owners, are almost entire large institutional also.  Bank of America, Morgan Stanley, Wells Fargo, UBS Group, JPMorgan Chase, LPL Financial, Envestnet Asset Management, Ameriprise Financial, TIAA Trust, Dimensional Fund Advisors, Beacon Capital Management, Betterment, Wealthfront Advisers, and Cove Street Capital

  Blackrock is pretty the same circular ownership: The Vanguard Group(9.08%), BlackRock Inc(7.02%), State Street Corporation(4.95%), Temasek Holdings Ltd(4.28%), Bank of America Corp(4.28%), Capital Research Global Investors(3.78%), Morgan Stanley(3.62%), Charles Schwab Corporation(3.14%), Capital World Investors(2.68%), Geode Capital Management(2.32%)

  State Street is ... of course, the same ownership: Vanguard Group Inc(13.23%), Blackrock Inc(8.71%), JPMorgan Chase(6.06%), State Street Corporation(4.83%), FMR, LLC(4.05%), Invesco Ltd(3.00%), Harris Associates L.P(2.73%), Geode Capital Management, LLC(2.66%), Dodge & Cox Inc(2.43%), Morgan Stanley(1.71%)
