The chairman of conglomerate Reliance Industries, the largest company in India by market cap, enjoyed a US$8-billion increase in his assets as of 3.09 p.m., according to real-time data by Forbes.

His gain was second only to the world’s top billionaire Elon Musk who added $10 billion to his fortune, which reached $878.5 billion.

In Asia, Ambani is richer than TikTok founder Zhang Yiming ($84 billion), infrastructure tycoon Gautam Adani ($79 billion), and Uniqlo founder Tadashi Yanai ($65 billion).

Ambani’s wealth has been boosted after the listing of his new digital and telecom platform business, Jio Platforms, which raised $3.2 billion last week following a 27% jump in its Mumbai debut.

Reliance Industries’ shares have risen 8.5% in the past five days.

Other world’s biggest wealth gainers on Tuesday were Amazon founder Jeff Bezos with a $4.7-billion increase, and Rob and Jim Walton, heirs of the Walmart retail giant, each with $3.8 billion added to his fortune.
