#	Company	Sector	Idx Wt	Founder / Key Insider	Insider Stake	Ownership Stack	Big Three (V+BR+SS)	Governance	Notes
1	NVIDIA NVDA · 6.99%	Info Tech	6.99%	Jensen Huang Co-founder & CEO since 1993	3.6%~$181B at current price	3.6% ~18% ~49% ~29%	~18% Vanguard ~8% BlackRock ~7% State St ~3%	Single class 1 share = 1 vote. Huang has no super-voting rights.	Huang has sold ~$1.5B in shares via 10b5-1 plan since 2024 but remains by far largest individual holder. No controlling stake despite founder status.
2	Apple AAPL · 6.17%	Info Tech	6.17%	No founder active Steve Jobs died 2011; Tim Cook is hired CEO	~0.3%Tim Cook ~$1.5B (options)	<1% ~19% ~52% ~29%	~19% Vanguard ~9% BlackRock ~7% State St ~3%	Single class Standard one-share-one-vote.	Warren Buffett (Berkshire) held ~5.5% until selling most of stake in 2024. Berkshire remains a top-5 holder. Widely owned — 29% retail is among highest in mega-caps.
3	Microsoft MSFT · 4.18%	Info Tech	4.18%	Bill Gates (residual) Co-founder; no longer on board (left 2020); Satya Nadella is hired CEO	~1%Gates Foundation ~<1%	~1% ~18% ~52% ~29%	~18% Vanguard ~9% BlackRock ~7% State St ~2%	Single class Gates sold most stake over decades; effectively institutionally controlled.	Classic post-founder mega-cap: founder long departed, now fully institutionally owned. Nadella holds ~$800M via options.
4	Amazon AMZN · 3.74%	Cons Disc	3.74%	Jeff Bezos Founder; stepped down as CEO 2021; Executive Chairman	~9%~$230B stake	~9% ~15% ~45% ~31%	~15% Vanguard ~7% BlackRock ~5% State St ~3%	Single class No super-voting. Bezos controls via economic stake alone.	Bezos has been selling ~$8–10B/yr since 2023 but remains dominant individual shareholder. Andy Jassy (CEO) owns <0.1%.
5	Alphabet (Google) GOOGL/GOOG · 6.16%	Comm Svcs	6.16%	Larry Page & Sergey Brin Co-founders; stepped back 2019 but remain board members	~11%~$460B combined	~11% ~15% ~44% ~30%	~15% Vanguard ~7% BlackRock ~6% State St ~2%	Dual class Class B shares (10 votes each) held by Page/Brin give them ~51% of voting control despite ~11% economic stake.	Index has two share classes (GOOGL Class A, GOOG Class C). Page & Brin economic stake ~5.5% each but voting majority via Class B.
7	Broadcom AVGO · 2.62%	Info Tech	2.62%	No founder active Hock Tan is hired CEO (joined 2006); current Broadcom is merger entity	~2%Hock Tan ~$35B	~2% ~18% ~50% ~30%	~18% Vanguard ~8% BlackRock ~7% State St ~3%	Single class Standard governance. Hock Tan controls via contractual authority only.	Broadcom is effectively a financial-engineering rollup. Tan's pay package ($160M in FY2024) is famously large. No founder narrative.
8	Tesla TSLA · 2.13%	Cons Disc	2.13%	Elon Musk Co-founder & CEO (joined early); largest individual shareholder	~13%~$186B stake	~13% ~15% ~37% ~35%	~15% Vanguard ~7% BlackRock ~5% State St ~3%	Single class No dual class. Musk controls via economic stake; Delaware court voided $56B pay package in 2024.	Highest retail ownership of any mega-cap (~35%). Musk's political activities 2024–25 visibly affected consumer sentiment and stock. Pay package saga ongoing.
9	Meta Platforms META · 2.10%	Comm Svcs	2.10%	Mark Zuckerberg Founder, Chairman & CEO since 2004	~13%~$185B stake	~13% ~15% ~45% ~27%	~15% Vanguard ~7% BlackRock ~6% State St ~2%	Dual class Class B shares give Zuckerberg ~57% voting control despite ~13% economic stake.	Dual-class means Zuckerberg has near-unilateral control. The $65B "Year of Efficiency" 2023 and AI pivot are decisions he made essentially unilaterally.
10	Micron Technology MU · 1.92%	Info Tech	1.92%	No founder active Founded 1978; Sanjay Mehrotra is hired CEO	~0.2%CEO & insiders	<1% ~17% ~55% ~28%	~17% Vanguard ~8% BlackRock ~7% State St ~2%	Single class	Pure institutional ownership story. Memory semiconductor — highly cyclical, purely investor-owned.

GLP-1 drugs drove ~4× stock appreciation 2022–24.
12	Berkshire Hathaway BRK.B · 1.59%	Financials	1.59%	Warren Buffett Founder-equivalent; Chairman & CEO since 1965; stepping down Jan 2026	~14%~$150B stake (Class A & B)	~14% ~13% ~40% ~33%	~13% Vanguard ~6% BlackRock ~5% State St ~2%	Dual class Class A shares (1500× votes) give Buffett effective control. BRK.A trades at ~$700K/share.	Buffett began succession in 2025 (Greg Abel takes over as CEO). A paradigmatic case of identity-owner running a publicly listed vehicle as a personal investment partnership.
13	Walmart WMT · 1.36%	Cons Staples	1.36%	Walton Family Descendants of Sam Walton (d.1992); family trust controls largest stake	~46%Walton Enterprises + family ~$420B	~46% ~5% ~16% ~33%	~5% Vanguard ~2% BlackRock ~2% State St ~1%	Single class No dual class needed — family controls via sheer economic dominance. CEO Doug McMillon is hired.	The Walton family is collectively the world's wealthiest family (~$280B+). Their 46% stake makes Big Three irrelevant — family votes override any institutional bloc.
14	JPMorgan Chase JPM · 1.31%	Financials	1.31%	Jamie Dimon Not founder; but 19-year CEO with large stake — a quasi-owner CEO	~0.8%~$7B stake	~0.8% ~18% ~54% ~28%	~18% Vanguard ~9% BlackRock ~7% State St ~2%	Single class	Dimon's 0.8% stake worth ~$7B is meaningful but not controlling. He is a long-tenure CEO who behaves more like an owner than most — retained & not sold most of his shares.
15	AMD AMD · 1.29%	Info Tech	1.29%	Lisa Su Not founder; hired CEO 2014; transformed AMD — a manager-owner by performance	~0.3%~$2.5B stock/options	<1% ~17% ~54% ~29%	~17% Vanguard ~8% BlackRock ~7% State St ~2%	Single class	Su is 1st cousin once removed of Jensen Huang (NVIDIA). AMD was near-bankrupt in 2014; Su's turnaround is the canonical professional-CEO-as-builder story.
17	Visa V · 0.95%	Financials	0.95%	No founder active Dee Hock founded Visa in 1970; Ryan McInerney is hired CEO	<0.5%Insiders collective	<1% ~17% ~55% ~28%	~17% Vanguard ~8% BlackRock ~7% State St ~2%	Single class	Pure institutional ownership; no activist history. A structurally monopolistic asset — once in the network, switching cost near-infinite.
26	Oracle ORCL · 0.65%	Info Tech	0.65%	Larry Ellison Co-founder 1977; Executive Chairman & CTO; largest S&P 500 founder stake by %	~43%~$190B — one of world's largest individual stakes	~43% ~5% ~16% ~36%	~5% Vanguard ~3% BlackRock ~2% State St ~1%	Single class No dual class needed — 43% economic stake is de facto control. Big Three collectively own less than Ellison.	Ellison's 43% stake is the most extreme founder-control case in the large-cap index without dual-class structure. He effectively owns Oracle. Safra Catz (hired CEO) owns <0.1%.
32	Home Depot HD · 0.52%	Cons Disc	0.52%	No founder active Founded 1978 by Bernie Marcus & Arthur Blank; Ted Decker is hired CEO	<0.5%Insiders collective	<1% ~17% ~54% ~29%	~17% Vanguard ~8% BlackRock ~7% State St ~2%	Single class	Arthur Blank (co-founder) owns Atlanta Falcons but minimal HD shares. Classic mature consumer retail — fully institutional.
39	Netflix NFLX · 0.46%	Comm Svcs	0.46%	Reed Hastings Co-founder; stepped down as Co-CEO 2023; remains board member	~2%~$6B stake	~2% ~17% ~52% ~29%	~17% Vanguard ~8% BlackRock ~7% State St ~2%	Single class	Hastings stepped down Jan 2023; Greg Peters & Ted Sarandos are co-CEOs. Founder still on board but influence is diminishing.
43	Palantir PLTR · 0.41%	Info Tech	0.41%	Alex Karp & Peter Thiel Karp: CEO & co-founder.

Highest retail ownership (~42%) of any in top 50 — a cult-retail stock. 96× revenue/market cap ratio reflects pure conviction bet on government AI contracts.

Big Three ~17% is the de facto floor for S&P 500 mega-caps.

Observation 01

The Walton–Ellison outliers

Walmart (46% Walton family) and Oracle (43% Ellison) are structurally different from every other company in the top 50. The Big Three together own less than 10% of each — their governance voice is effectively moot. These are public companies that function like private ones.

Observation 02

The 17% floor

For companies without a dominant founder or family, the Big Three (Vanguard + BlackRock + State Street) consistently own approximately 17–20% of the company. This is not a choice — it is a mechanical outcome of index weighting. These three entities are structurally compelled to be among the largest shareholders of every major US public company simultaneously.

Observation 03

Dual-class: voting vs economic

Alphabet, Meta, and Palantir all have dual-class structures. Page & Brin control Alphabet's votes with ~11% economic stake. Zuckerberg controls Meta's votes with ~13%. This means the companies commanding ~23% of the S&P 500 index weight are effectively controlled by 3–4 individuals, regardless of what the other 80% of shareholders vote.

Observation 04

The owner–investor performance gap

The companies with meaningful founder stakes (Walmart, Oracle, Amazon, Meta, Alphabet, NVIDIA, Tesla, Berkshire) account for roughly 15% of index weight but have generated disproportionately higher long-term returns. Bain found founder-led firms outperformed 2.1× in TSR since 2015. The data suggests skin-in-the-game matters — owners make different decisions than managers.

Observation 05

Retail as signal, not noise

Tesla (~35%) and Palantir (~42%) have the highest retail ownership of any mega-caps. This is a governance and volatility signal: retail holders tend to be more sentiment-driven, hold shorter-term, and are more susceptible to personality-driven narratives. The extreme valuations of both companies are partly a retail-conviction phenomenon.

Observation 06

The post-founder problem

Apple (post-Jobs), Microsoft (post-Gates), Intel (post-Grove), Netflix (post-Hastings), ServiceNow (post-Luddy) — these transitions mark a shift from owner-operator to institutional-manager. The company's capital allocation becomes more conservative, more buyback-driven, and more focused on quarterly guidance. The index is slowly shifting from founder-owned to manager-operated.
