Thai Lee Net Worth

Thai Lee has an estimated net worth of $7.4 billion, according to Forbes Real-Time Billionaires, Thai Lee profile (figures as of October 20, 2026). That is up from $2.1 billion in 2019.

Thai Lee is the co-owner, CEO and president of SHI International, an IT provider in the technology industry. She built her career after studying biology and economics at Amherst College in 1980 and earning an MBA from Harvard Business School in 1985. Before SHI, she worked at Procter & Gamble and American Express. Forbes reported SHI as the largest woman-owned business in the US in 2012, which helped raise her public profile.

Her wealth comes from SHI International, the company she and Leo KoGuan bought in 1989 for less than $1 million. That software reseller became the business now known as SHI. Forbes says she owns 60% and he owns 40%. Lee leads a company with $16 billion in gross sales and 17,000 customers, including Boeing and AT&T. SHI also put $20 million into an AI & Cyber lab using NVIDIA technology for customer testing.

How Thai Lee built her fortune

Lee made her money by turning a small software reseller into SHI International, a major IT provider. She and Leo KoGuan bought the predecessor company in 1989 for less than $1 million. Today, Forbes says she owns 60% of the business. That ownership stake is the core of her wealth. Her career before SHI included roles at Procter & Gamble and American Express, but SHI is the main reason she became a billionaire.

SHI's scale explains why Lee's wealth is so large. Forbes says the company has $16 billion in gross sales and serves 17,000 customers, including Boeing and AT&T. The business sells technology products and services, and it is also spending on newer areas. SHI recently invested $20 million in an AI & Cyber lab, where it tests AI solutions for customers using NVIDIA's technology. Lee's role as CEO ties her fortune closely to SHI's performance.

Forbes net worth update

Forbes has steadily raised its estimate of Lee's fortune over time. It put her net worth at $2.1 billion in 2019, then $3 billion in 2020 and $3.2 billion in 2021. The estimate moved to $4.1 billion in 2022 and $4.8 billion in 2023. Those increases tracked the value of her stake in SHI, the company that drives her wealth through its large customer base and strong sales.

The upward trend continued with Forbes estimating $5.3 billion in 2024, then $7 billion in 2025 and $7.5 billion in 2026 on its World's Billionaires list. Forbes' real-time tracker later showed $7.4 billion in October 2026, and that is the current figure as of October 20, 2026. Because Lee's fortune is tied to her 60% ownership in SHI, changes in the estimate reflect Forbes' updated view of that business and its market position.
