Estimate
Current Assessment
Chang built TSMC, but his personal fortune appears to come from a small stake in the company rather than control of it. A 2024 Wall Street Journal profile reported that he owned roughly 0.5% of TSMC. Forbes-linked reporting places his 2026 net worth around US$8.5 billion, which is consistent with the rise in TSMC's market value after the AI-chip boom lifted semiconductor valuations.
Key caveats
- The exact current share count is not public in the sources reviewed.
- Company revenue and market capitalization are not counted directly as personal wealth.
- Private assets, taxes, family trusts, and liabilities could move the estimate materially.
Evidence gaps
- Current beneficial ownership filing or equivalent Taiwan disclosure
- Direct licensed access to Forbes' current profile details
- Family ownership and pledged-share data
