Biography
Steve Ballmer spent 13 years as Microsoft CEO (2000-2014), growing revenue from $22 billion to $78 billion and returning tens of billions to shareholders — while also missing the smartphone revolution, ceding search to Google, and nearly watching Microsoft become irrelevant. His most famous moment came in 2007 when he laughed dismissively at the original iPhone: 'No chance that the iPhone is going to get any significant market share. No chance.'
Ballmer stepped down as CEO under shareholder pressure in 2014 — but cleverly retained his Microsoft stock, which has since appreciated massively under Satya Nadella's leadership. By never diversifying, he became one of the wealthiest people on Earth without making a single new investment. His 4% Microsoft stake is worth over $100 billion.
Since leaving Microsoft, Ballmer is primarily known as the owner of the Los Angeles Clippers NBA team (purchased for a then-record $2 billion in 2014) and as the founder of USAFacts.org, a civic data project documenting US government spending. He opened the Intuit Dome in Inglewood in 2024 — one of the most technologically sophisticated sports arenas in the world.
Did You Know?
Ballmer was employee #30 at Microsoft and has never needed to make another investment — his entire net worth is Microsoft stock he held for decades. He once owned more Microsoft shares than Bill Gates.
Elon MuskvsSteve Ballmer
Ballmer and Musk occupy different eras of tech: Ballmer is the last great boomer tech CEO; Musk is the first AI-era tech emperor. Their companies overlap in AI (Microsoft/OpenAI vs xAI) and enterprise software, but the biggest contrast is cultural — Ballmer's sweaty stage performances vs Musk's 3am tweet storms.

Rivalry Timeline
Ballmer laughs at the iPhone: 'No chance it gets any significant market share.' Musk tweets this quote periodically as a cautionary tale about dismissing disruption.
Ballmer buys the LA Clippers for $2B — then a record for an NBA franchise. Musk is busy landing the first Falcon 9 booster.
Microsoft invests $10B in OpenAI, making it the most powerful AI partnership in corporate tech. xAI is not yet founded. Ballmer's Microsoft stock surges.
Musk sues OpenAI, alleging it violated its non-profit charter by prioritizing Microsoft's commercial interests. Microsoft — and by extension Ballmer's Microsoft stake — is implicitly in the crosshairs.
