Steve Ballmer's net worth is roughly $130 billion to $145 billion as of February 2026, making him one of the wealthiest people on Earth. Forbes' Real-Time Billionaires List pegged him at $130 billion and 14th globally that month, while the Bloomberg Billionaires Index put him higher, at roughly $145 billion and 13th-richest. Ballmer built almost none of that fortune as a founder. He spent 34 years as a Microsoft employee and executive, and his wealth today still tracks the company's stock price far more than any business he has started since.

How Did Ballmer Accumulate This Much Wealth?
Ballmer joined Microsoft on June 11, 1980 as its 30th employee and the company's first business manager, hired directly by Bill Gates, according to Wikipedia's account of his career. He became CEO on January 13, 2000 and ran the company until February 4, 2014, when Satya Nadella succeeded him.
That early hire date matters because it meant Ballmer received Microsoft stock and stock options for more than three decades while the company grew into one of the world's most valuable corporations. By July 2024, Fortune reported his net worth had reached $157 billion, making him the sixth-richest person alive and putting him ahead of Gates — a milestone Fortune called unprecedented, since no one else has built a fortune over $100 billion purely through salary and equity as an employee rather than as a company founder.
Why Microsoft Stock Still Drives His Fortune
When Ballmer stepped down as CEO in 2014, he chose not to sell down his position the way many retiring executives do. He kept approximately 333 million shares, around a 4% stake in the company, according to Fortune's reporting on his holdings.
That decision means Ballmer's net worth rises and falls almost in lockstep with Microsoft's share price, rather than being spread across a diversified portfolio of unrelated assets. He has sold some shares over the years — in November 2010 he sold about 49.3 million shares for roughly $1.3 billion, cutting his stake by about 12% and leaving him with about 359 million shares, or 4.2% of the company, according to The Register's coverage of the sale. At the time, that still made him the second-largest individual shareholder behind Gates.
- A holder this concentrated in one stock sees wealth swings most diversified billionaires don't.
- The gap between the Bloomberg and Forbes estimates for Ballmer reflects differences in how each index values his Microsoft stake and other holdings on a given day, not a dispute over what he owns.
The Los Angeles Clippers and the Intuit Dome
Ballmer's highest-profile business outside Microsoft is the Los Angeles Clippers. Shelly Sterling agreed in May 2014 to sell the team to Ballmer for $2 billion, a record price for an NBA franchise at the time, with the league's Board of Governors later approving the sale, as reported by ESPN via the Washington Informer. That purchase has turned into one of the better-performing assets in his portfolio.
Forbes' 2025 NBA franchise valuations list the Clippers at $7.5 billion, up 36% year-over-year, with $569 million in revenue and $154 million in operating income — gains Forbes attributed to a 61% revenue jump after the team moved into its new arena, according to Forbes' valuation coverage. Ballmer personally financed that new arena, the Intuit Dome in Inglewood, California. The project's cost ran well above its original estimate of roughly $1.2 billion because of post-COVID materials and supply-chain inflation, and Ballmer separately spent more than $60 million on land and about $400 million to buy a nearby venue, according to arena coverage reported by Yahoo Sports.
What Has Ballmer Done With the Money?
Ballmer and his wife, Connie, have directed a significant share of their fortune into philanthropy through Ballmer Group. In March 2022, the couple pledged more than $425 million to the University of Oregon to fund a children's behavioral-health institute, part of a giving effort the Chronicle of Philanthropy estimated at roughly $2.1 billion in combined cumulative giving as of that year, according to the Chronicle's reporting. That scale of giving sits alongside his two major holdings — Microsoft stock and the Clippers — as the third visible piece of how Ballmer's wealth moves through the economy rather than sitting static in a single account.
- Microsoft stake: roughly 333 million shares, about 4% of the company, as of 2024.
- Los Angeles Clippers: purchased for $2 billion in 2014, valued at $7.5 billion in 2025.
- Intuit Dome: a stadium project Ballmer financed personally, exceeding its original $1.2 billion estimate.
- Ballmer Group philanthropy: roughly $2.1 billion in cumulative giving as of 2022, including a $425 million pledge to the University of Oregon.
Frequently Asked Questions
Why do estimates of Ballmer's net worth differ between Bloomberg and Forbes?
The two trackers calculate his wealth using different methodologies and timing for valuing his Microsoft shares and other assets, which is why Bloomberg's February 2026 estimate of roughly $145 billion sits above Forbes' $130 billion figure from the same month.
Did Ballmer build his fortune by founding a company?
No. He earned his wealth as a salaried Microsoft employee and executive from 1980 to 2014, which Fortune noted makes him the only person to build a fortune over $100 billion that way rather than as a founder.
How much did Ballmer pay for the Los Angeles Clippers?
He agreed to pay $2 billion in May 2014, a record price for an NBA franchise at the time.
