Gautam Adani, a prominent Indian billionaire and close ally of Prime Minister Narendra Modi, is facing serious legal troubles after US federal prosecutors accused him of orchestrating a $250 million bribery scheme. The allegations, which claim that Adani and his executives concealed bribes to Indian officials for lucrative contracts, have already caused a substantial drop in the market value of his companies and raised concerns about the implications for India’s economy and politics. As allegations mount, Adani’s global expansion ambitions could also be at risk.
