Own a Piece of a Company
What the World's Richest Person's Fortune Could Buy Outright
Elon Musk is worth an estimated $405.74B right now. We measured that fortune against the live market value of 20 of the world's biggest public companies — from Apple and Nvidia to Reliance Industries and Saudi Aramco — to see exactly how much of each Elon could buy outright, today, with cash alone.
Elon could buy Alibaba, Nestlé, LVMH, Toyota, Reliance Industries, HDFC Bank, and Tata Consultancy Services outright — 100% of each company — and still have money left over. Alibaba alone is valued at $282.76B.
Among the rest, Elon's fortune would buy about 80% of Tencent (market cap $505.90B), tapering down to roughly 38% of Berkshire Hathaway. Market caps move every trading day, so these percentages shift right along with them.
Frequently Asked Questions
- Could Elon Musk really buy a company outright?
- Only in theory — this compares net worth (mostly stock in one company) to another company's total market value. Buying real shares at scale would move the price, and most of Elon's wealth is tied up in their own holdings, not free cash.
- Which companies are included in this comparison?
- 19 major global companies across the US, India, Europe, the Middle East, and Asia — the same list used in our "Own a Piece of a Company" calculator.
- How often does this update?
- Every time the page loads — both the billionaire's net worth and every company's market cap are pulled live, so the percentages here are never more than a few minutes stale.
