India's young billionaires rise on digital infrastructure

India's new generation of self-made billionaires has a median age of 33, less than half the 67-year median for all Indian billionaires. Fintech is the biggest wealth creator, built on digital infrastructure like UPI, Aadhaar, and cheap data, plus a matured venture-capital ecosystem. Earlier fortunes like those of Dhirubhai Ambani and Azim Premji took nearly a lifetime; today's founders compress that journey into a decade or two.
