Hindenburg Research, which targeted Adani Group in the past few years, declared its closure on January 15. Nate Anderson, the founder of the US-based research firm, said he has taken a decision to disband Hindenburg in a statement released on its website.
This announcement marked the end of an era for a company that had recently made headlines in India due to its influential reports, which triggered many controversies. The Hindenburg Research allegations shook Adani Group shares, wearing away Adani's personal wealth by over USD 100 billion. By February 27, the market capitalization of Adani Group companies had fallen below Rs 7 lakh crore, down from over Rs 19 lakh crore before the report was published in January.

Apart from the Adani Group report, the Hindenburg report also directed other companies globally who once were the talk of the town:
Hindenburg vs. Nikola: Trevor Milton's Fraud Allegations
In September 2020, Hindenburg Research published a report accusing Nikola Corporation of misleading investors about its technology, operations, and other prospects. The report triggered a massive controversy surrounding the electric vehicle (EV) startup. Hindenburg's report alleged that Nikola's founder, Trevor Milton, had exaggerated claims about the company's technology, particularly its hydrogen fuel-cell trucks, and even made a promotional video that misled investors into believing the company's trucks were operational when, in fact, they were not.
The fallout from the Hindenburg report was quite massive. Nikola's stock price plummeted, and the company had to face numerous investigations by the Securities and Exchange Commission (SEC) and the Department of Justice (DOJ). Trevor Milton, the company's founder and former executive chairman, was eventually charged with securities fraud and accused of misleading investors, who later stepped down from the position.
Hindenburg Allegations Against Carl Icahn and Icahn Enterprises
Hindenburg Research released a report in May 2023, alleging that Icahn Enterprises L.P. (IEP), led by Carl Icahn, operated with a "Ponzi-like" economic structure. The report stated that IEP's major dividends were funded by new investors, which raised major concerns about the company's financial grounds. After the release of Hindenburg's report, IEP's stock price experienced a sharp decline, falling by 20% on the same day, as per data on Wikipedia. In response to the allegations, IEP announced in August 2023 that it would reduce its dividend by half due to financial pressure.
The following year in August, the U.S. Securities and Exchange Commission (SEC) charged Carl Icahn and Icahn Enterprises as they failed to disclose billions of dollars that were secured as personal loans by IEP stock. The SEC's investigation resulted in a USD 2 million fine for Icahn Enterprises and a USD 500,000 fine for Carl Icahn. Both parties neither admitted nor denied the SEC's findings as part of the settlement, as per The Guardian's report.
Hindenburg Research Reports on Block Inc
A Hindenburg report in March 2023 alleged that Block Inc., the company behind Cash App and Square, falsely reported the number of users along with allowing the fraudulent activities to take place. Hindenburg claimed that Block Inc. had exaggerated the number of users on its Cash App platform and said that the reported figures were significantly higher than actual active users. Jack Dorsey, Block Inc.'s co-founder, however, denied the claims and stated the report as factually incorrect. However, Block Inc.'s stock after the report declined severely due to negative investor sentiments.
Hindenburg Accused SEBI Chief Madhabi Puri Buch of Conflicts
In a recent Hindenburg Research report released in August 2023, it was alleged that Madhabi Puri Buch, the chairperson of India's Securities and Exchange Board (SEBI), and her husband, Dhaval Buch, had conflicts of interest due to investments in offshore entities linked to the Adani Group. SEBI, under Madhabi Puri Buch's leadership, denied the allegations and said that the regulatory body operates independently and has no bias in this regard.
