New York-based Hindenburg Research shocked the markets when it alleged in a scathing January 24 report that the Adani Group "engaged in a brazen stock manipulation and accounting fraud scheme over the course of decades."

The report hit investor sentiment and sent Adani-related stocks into a tailspin, losing over $150 billion in about five weeks, according to Bloomberg. This also sent founder Gautam Adani's wealth plunging with his net worth halved to about $60 billion so far this year, per Bloomberg Billionaires Index. 

The Adani Group defended itself vigorously against Hindenburg's accusations, but the research firm also doubled down on its initial report.

The fallout from the short seller's report spilled over into the broader Indian markets and prompted concerns about corporate governance and debt in the country.

Shares of Adani Enterprises, the conglomerate's flagship company, were down 0.7% at last check. The stock is down about 53% so far this year.

Hindenburg Research did not immediately respond to Insider's request for comment sent outside regular business hours.
