Who Owns Microsoft? Shareholder Structure Breakdown
Key Takeaways:
- Steve Ballmer is the largest individual owner (4.48%, ~$150B)
- Bill Gates now owns just 1.34% after decades of donations
- Vanguard leads institutional ownership at 9% (~702M shares)
- Institutions control 82% of all Microsoft shares
- No single entity controls the company
Who owns Microsoft? Ballmer’s got 4.48%, Gates is down to 1.34%, and Vanguard plus other index funds hold the lion’s share. So if someone asks who owns Microsoft, tell them it’s mostly passive index funds and one very patient ex-CEO. The company trades on NASDAQ under MSFT, anyone with a brokerage account can buy in.
Here’s the full breakdown based on recent SEC filings. You’ll find exact share counts and percentages for every major holder.
Microsoft Ownership Structure Overview
Here’s how it breaks down (Q4 2025 data):
| Investor Type | Percentage | Approximate Shares |
|---|---|---|
| Institutional Investors | 82.23% | 6.11 billion |
| Company Insiders | 6.24% | 464 million |
| Retail Investors | 11.54% | 858 million |
Total shares outstanding: 7.43 billion. Microsoft only has one class of stock, so every share gets one vote. No founder shares with extra voting power like you see at Google or Facebook.
Who Owns Microsoft – Institutional Shareholders
Big asset managers own most of Microsoft. They pool money from pension funds, 401(k) plans, and regular investors who buy index funds. When these firms vote on company matters, it can swing board elections and merger decisions.
Vanguard: Top Microsoft Shareholder
Vanguard sits at the top with roughly 702 million shares, about 9% of Microsoft. But here’s the thing: Vanguard doesn’t pick stocks. They just buy whatever’s in the index. So their massive position says more about Microsoft’s size in the market than any belief in the company.
BlackRock: Second Largest
BlackRock comes in second with about 591 million shares (7.6%). Same story here: iShares ETFs and institutional money. Put Vanguard and BlackRock together and you’re looking at 16% of all Microsoft stock in just two firms.
State Street: Third Place
State Street rounds out the “Big Three” with around 300 million shares (4%). They run the SPDR S&P 500 ETF, one of the oldest and biggest index funds out there.
Other Major Institutional Holders
| Institution | Shares (millions) | Percentage |
|---|---|---|
| Vanguard Group | 702 | 9.0% |
| BlackRock | 591 | 7.6% |
| State Street | 300 | 4.0% |
| FMR (Fidelity) | 90 | 1.2% |
| T. Rowe Price | 75 | 1.0% |
| Capital Research | 68 | 0.9% |
| Geode Capital | 55 | 0.7% |
Add up the top 10 institutions and they control over 33% of Microsoft. That sounds like a lot of power, but these passive managers almost always vote with whatever management recommends. They only push back when something really controversial comes up.
Who Owns Microsoft – Individual Shareholders
Individual stakes look small next to the institutions, but we’re still talking about positions worth over $150 billion. Two names matter here.
Steve Ballmer: Largest Microsoft Shareholder
Steve Ballmer owns more Microsoft than anyone else walking the planet. We’re talking 333 million shares, 4.48% of the whole company. At today’s prices? North of $150 billion. He joined as employee number 30 back in 1980, ran the place as CEO from 2000 to 2014, then just… kept his shares.
What makes Ballmer different:
- Holds more Microsoft stock than any other person
- Receives over $1 billion yearly in dividends
- Keeps 80%+ of his portfolio in MSFT stock
- Has not sold significant shares since 2003
Since Ballmer stepped down, the stock’s up about 1,000%. Nadella pushed hard into Azure and AI stuff. Turned out to be the right call.
Bill Gates: From 45% to 1.34%
Gates started Microsoft with Paul Allen back in 1975. When they went public in ’86, he owned 45%. Now he’s got about 1.34%.
He’s been selling and giving away shares for 30 years to fund the Gates Foundation. In late 2025, the foundation dumped 65% of its Microsoft position in one quarter. Went from $13.9 billion down to $4.76 billion. The foundation needs cash for grants, and keeping everything in one stock doesn’t make sense for a charity.
Microsoft Executive Shareholdings
Current executives hold smaller stakes. Per September 2025 SEC filings:
| Executive | Position | Shares | Value (approx.) |
|---|---|---|---|
| Satya Nadella | CEO | 900,572 | $430M |
| Amy Hood | CFO | 465,746 | $223M |
| Bradford Smith | Vice Chair | 402,131 | $192M |
Who Owns Microsoft: Ownership Changes Over Time
Microsoft’s ownership structure shifted dramatically since the 1986 IPO. Here’s the evolution:
| Year | Bill Gates | Paul Allen | Steve Ballmer | Institutions |
|---|---|---|---|---|
| 1986 (IPO) | 45% | 25% | 8% | ~15% |
| 2000 | 14% | 5% | 4% | ~60% |
| 2014 | 3% | 2% | 4% | ~70% |
| 2026 | 1.34% | 0% (estate sold) | 4.48% | ~82% |
Paul Allen died in 2018. His estate gradually sold off the shares. Gates kept selling and donating. Ballmer? Didn’t budge.
Index funds changed everything. When Vanguard’s Total Stock Market fund hit a trillion dollars, it had to buy Microsoft stock proportional to the company’s market size. Same with every other index fund. That’s why institutions now own 82% and climbing.
Voting Power and Corporate Control
Microsoft keeps it simple: one share, one vote. No fancy dual-class setup like you see at Meta or Alphabet where founders get 10x voting power. Everyone plays by the same rules here.
Voting power by shareholder:
| Shareholder | Voting Power | Can Block Major Actions? |
|---|---|---|
| Vanguard Group | 9.0% | No |
| BlackRock | 7.6% | No |
| Steve Ballmer | 4.48% | No |
| State Street | 4.0% | No |
| Bill Gates | 1.34% | No |
Nobody can block a merger or fire the board on their own. You need 50%+ of votes for anything big. Good for small investors, but it also means management has a lot of room to do what they want.
The Big Three together hold about 21% of votes. They use advisory firms like ISS to figure out how to vote, and mostly just rubber-stamp whatever management asks for. Takes something pretty bad to get them to vote no.
What This Means in Practice
With ownership spread this thin, nobody’s really in charge except management. Here’s how it plays out:
- No boss: Nobody can tell Satya Nadella what to do
- Board calls the shots: 13 independent directors, no founder control
- Passive investors stay passive: Vanguard and BlackRock vote yes on almost everything
- Ballmer could cause trouble: 4.48% is enough to rally other shareholders if he wanted to
Works great when the stock keeps going up. If Microsoft starts missing numbers, there’s nobody to hold management accountable quickly. For now though, AI and cloud growth keep everyone happy.

Does Bill Gates still own Microsoft?
A little. About 1.34%, way down from 45% at the IPO. He’s been selling and donating for years. The Gates Foundation gets most of it. Microsoft ownership isn’t really his thing anymore.
Which institution owns the most Microsoft shares?
Vanguard, with around 702 million shares (9%). BlackRock is close behind at 591 million (7.6%). State Street takes third at 300 million (4%). These three together own over 20% of Microsoft.

What percentage of Microsoft do institutional investors own?
About 82%. Company insiders have 6.24%, and regular retail investors hold the remaining 11.54%.
Does Warren Buffett own Microsoft stock?
Nope. Berkshire Hathaway has zero Microsoft shares. Buffett says being friends with Gates made it feel weird to invest. He’s stuck to that for decades even though Microsoft crushed it. Apple’s his only big tech bet.
How much is Microsoft worth in 2026?
Around $3.8 trillion market cap as of late 2025. Top three in the world, right there with Apple and NVIDIA. Azure and Copilot AI are driving a lot of that.
Bottom Line
Nobody owns Microsoft. Not really. Vanguard has the biggest chunk at 9%, Ballmer’s the top individual at 4.48%, and Gates is down to 1.34% after giving most of it away.
The scattered ownership keeps activists away and lets management think long-term. Whether that’s good or bad depends on how much you trust Satya Nadella. So far, the stock price says investors trust him plenty.
