The South Korean automaker plans to raise up to $3 billion at a valuation of about $20 billion, sources previously told Reuters.
This will make it the first carmaker in India to go public in two decades, with market leader Maruti Suzuki issuing an IPO in 2003.
Hyundai India did not respond to a request for comment outside business hours.
The automaker is trying to regain market share from fast-growing domestic rivals such as Tata Motors by expanding its SUV range.
Three sources with knowledge of the company's plans previously told Reuters it plans to launch its first India-made electric vehicle early next year and introduce at least two gasoline-powered models for the market from 2026. India is the third-largest revenue generator globally for Hyundai after the US and South Korea, and it has already invested $5 billion in the country, with a commitment to invest another $4 billion over the next decade. Separately, Sebi also approved the IPO of SoftBank-backed food delivery giant Swiggy, which is targeting a valuation of about $15 billion and aims to raise $1-1.2 billion, according to multiple sources familiar with the matter.
