Kapur, the Indian auto-components billionaire and chairman of Sona BLW Precision Forgings Ltd. (Sona Comstar), died in England on June 12, 2025. He was 53.
Kapur collapsed while playing polo at Guards Polo Club in Windsor. Sona Comstar and the Automotive Component Manufacturers Association of India (ACMA) confirmed his death. Initial statements described the event as a sudden heart attack; a later Surrey Coroner’s report attributed his death to natural causes, specifically left ventricular hypertrophy and ischemic heart disease.

Under his leadership, Sona Comstar expanded beyond conventional automotive components and increased its focus on electric-vehicle driveline systems and other mobility technologies. The company supplies components used in passenger vehicles, commercial vehicles and electric-vehicle applications.
What was Sunjay Kapur’s cause of death?
Kapur collapsed during a polo match at Guards Polo Club in Windsor, England, on June 12, 2025. Sona Comstar’s initial announcement referred to a sudden heart attack.
In August 2025, reporting on a Surrey Coroner’s finding gave a more specific medical explanation. The coroner determined that Kapur died of natural causes, listing:
- Left ventricular hypertrophy, a thickening of the heart’s main pumping chamber; and
- Ischemic heart disease, a condition in which reduced blood flow affects the heart muscle.
Early reports suggested that Kapur may have swallowed or been stung by a bee during the match and suffered anaphylactic shock. That account was not established by the coroner’s findings. The later official finding identified cardiac disease and natural causes instead.
How much was Sunjay Kapur worth?
Forbes estimated Kapur’s net worth at approximately $1.2 billion in 2025. That estimate was based on Forbes’ April 1, 2025 billionaire assessment and largely reflected his stake and connection to Sona Comstar.
A billionaire ranking is not the same as cash held in a bank account. Such estimates generally depend on the market value of publicly traded shares, privately held assets and other known holdings. The figure can therefore rise or fall with the company’s share price and with changes in the value of other assets.
For personal-finance purposes, the important distinction is between:
| Term | What it means |
|---|---|
| Net worth | The estimated value of assets minus debts |
| Company stake | Ownership in a business, which may not be immediately liquid |
| Liquid wealth | Money or investments that can generally be accessed quickly |
There is no verified public breakdown showing how much of Kapur’s wealth was held in cash, listed shares, private investments, property or other assets.

Kapur helped guide Sona Comstar’s transition toward higher-value and technology-focused automotive components. The business became increasingly associated with electric-vehicle driveline products and mobility systems rather than relying only on traditional forged components.
His role combined ownership, board leadership and operational management during different stages of his career. That matters when assessing his financial legacy: the value associated with Kapur was tied not just to inheritance, but also to the growth and strategic direction of the company he led.
After his death, responsibility for the company’s operations and governance rests with its board and management under the company’s formal succession arrangements. Public reports should not be treated as confirmation of the eventual distribution of his personal estate or the ownership of any shares.
Kapur’s role in India’s auto-components industry
In addition to his work at Sona Comstar, Kapur held a prominent industry position. He served as president of ACMA and was described by the organization as its immediate past president in 2024.

Personal and family background
Kapur was previously married to Bollywood actor Karisma Kapoor and later married Priya Sachdev. Those relationships formed part of his public profile, but his principal business significance came from his leadership of Sona Comstar and his position in India’s automotive-components sector.

- From the acclaimed, award-winning author of Alexander Hamilton: here is the essential, endlessly engrossing biography of John D. Rockefeller, Sr.—the Jekyll-and-Hyde of American capitalism.
- In the course of his nearly 98 years, Rockefeller was known as both a rapacious robber baron, whose Standard Oil Company rode roughshod over an industry, and a philanthropist who donated money lavishly to universities and medical centers.
- He was the terror of his competitors, the bogeyman of reformers, the delight of caricaturists—and an utter enigma.
- Separate business ownership from management. A founder or family member may be both a shareholder and an executive. Those roles require different succession plans.
- Document access to assets. Families should maintain an up-to-date inventory of bank accounts, brokerage accounts, insurance policies, property, company shares and digital assets.
- Use appropriate estate documents. Wills, trusts, nominations and powers of attorney can reduce uncertainty, although the right structure depends on the person’s country, assets and family circumstances.
- Plan for key-person risk. Companies with substantial value tied to one leader need board-level succession planning, delegated authority and clear communication procedures.
- Do not confuse valuation with spendable money. A large shareholding may be valuable but difficult to sell quickly without affecting the price or triggering tax and regulatory consequences.
