Adani's gains this year total $17.1 billion—more than double the $8.02 billion rise in Ambani's wealth during the same period. The sharp upswing comes after India's market regulator, the Securities and Exchange Board of India (SEBI), cleared the Adani Group in its final ruling on the Hindenburg short-selling case. SEBI dismissed allegations of fund routing and related-party transactions, finding no regulatory violations.
