Ilyas Khan Net Worth

Ilyas Khan has an estimated net worth of $1.4 billion, according to Forbes Real-Time Billionaires, Ilyas Khan profile (figures as of October 20, 2026).

Ilyas Khan is a British technologist and businessman known for building companies around quantum computing. He started in finance at Schroders, then moved to Hong Kong and worked with Citi Group and Nomura. Later, he ran the Asia-focused tech accelerator Tech Pacific and took it public on the Hong Kong Stock Exchange in 2000. He also founded Stanhill Capital Partners in 1998 during the 20 years from 1989–2009 that he lived and worked in Hong Kong.

His biggest business break came in 2014, when he started Cambridge Quantum after a conversation with Stephen Hawking inspired him to launch a quantum software company. In 2021, Cambridge Quantum merged with Honeywell's trapped ion computer unit to create Quantinuum. Honeywell then took Quantinuum public on the Nasdaq in June 2026. Khan is the company's Chief Product Officer and Vice-Chairman, and he owns around 15% of the stock, which is the main driver of his wealth.

How Ilyas Khan makes money

Khan built his fortune through finance, technology investing, and quantum computing. Early in his career, he worked at Schroders, Citi Group, and Nomura. He later led Tech Pacific, an accelerator focused on Asian technology businesses, and took it public in 2000. He also founded merchant banking firm Stanhill Capital Partners in 1998. Those roles gave him experience backing companies, raising capital, and spotting areas where new technology could become a business.

The biggest source of his wealth is Quantinuum. Khan founded Cambridge Quantum in 2014 to focus on quantum software and quantum cybersecurity. In 2021, that company combined with Honeywell's trapped ion computer unit. After the merger, he stayed in a senior leadership role and later became Vice-Chairman and Chief Product Officer in 2023. When Quantinuum listed on Nasdaq in June 2026, his stake of around 15% became the clearest measure of the value tied to his work in quantum computing.

Forbes net worth and the key driver

Forbes estimated Khan's net worth at $1.4 billion on its real-time billionaires tracker as of October 20, 2026. That figure is closely linked to Quantinuum, the company he helped build from Cambridge Quantum and the Honeywell deal in 2021. Because he owns around 15% of the business and serves as Chief Product Officer and Vice-Chairman, changes in the company's public market value can have a large effect on how Forbes values his fortune.

The public listing in June 2026 was the main money milestone in his recent story. It turned years of work in quantum software into a publicly traded holding that investors could price in real time. Before that, his background included banking, tech acceleration, and merchant banking, but Quantinuum is the centerpiece. Forbes places him in the Technology industry, and his billionaire status rests mainly on the stock value of the quantum computing company he founded and helped take to market.
