Hindenburg Research LLC was an American investment research firm founded in 2017 by Nathan Anderson, focusing on activist short-selling strategies. The firm took its name from the 1937 Hindenburg disaster, symbolizing a preventable, human-caused catastrophe. It became known for releasing reports that accused corporations of fraud and misconduct. Among the companies scrutinized by Hindenburg were Super Micro Computer, Adani Group, Nikola, Clover Health, Block, Inc., Kandi, and Lordstown Motors.
Hindenburg advocated for short-selling as an essential mechanism to uncover fraudulent activities and safeguard investors' interests. As of 2024, the company employed 11 staff members and was based in New York City. The firm ceased operations in January 2025, with founder Nathan Anderson announcing its closure on the official website. At that time, the Wall Street Journal described Hindenburg as "Wall Street’s Pre-Eminent Short Seller." Its concluding investigation centered on Carvana.
Operations
Hindenburg Research compiled its investigative reports by examining publicly available documents, internal company materials, and conducting interviews with employees. These reports were initially distributed to Hindenburg’s limited partners, who, alongside the firm, established short positions in the targeted companies prior to making the findings public. The firm’s revenue was generated through profits realized from declines in the stock prices of these companies.
Nikola report
In September 2020, Hindenburg Research released a report accusing Nikola Corporation, a collaborator with General Motors on hydrogen and battery electric trucks, of orchestrating "an elaborate fraud based on numerous falsehoods," implicating founder Trevor Milton in deceptive conduct. Following this publication, Nikola's share price plummeted by 40%, prompting an investigation by the SEC. Milton initially refuted the accusations but subsequently resigned as Executive Chairman and was convicted of wire and securities fraud charges. Nikola later disclosed substantial costs related to regulatory and legal proceedings resulting from the report. On February 19, 2025, Nikola filed for Chapter 11 bankruptcy protection, citing consequences linked to Hindenburg’s allegations.
Clover Health report and Chamath Palihapitiya
In February 2021, Hindenburg issued a report concerning Clover Health’s Medicare Advantage program, alleging that the company failed to inform investors about an ongoing Department of Justice inquiry. The report also criticized billionaire Chamath Palihapitiya for insufficient due diligence and for providing misleading information during Clover’s SPAC public offering. Hindenburg clarified that it held no financial positions in Clover Health. In response, Clover Health denied all accusations and confirmed receipt of a notice from the SEC.
Adani Group report
In January 2023, Hindenburg revealed its short positions against India's Adani Group while raising concerns over debt levels and accounting irregularities. The firm's report accused the conglomerate of manipulating stock prices and engaging in accounting fraud over several decades, resulting in a significant drop in Adani’s share value. By February 2023, the group had lost $150 billion in market capitalization, with Gautam Adani’s ranking among the world’s wealthiest individuals falling from third to thirtieth place.
The Adani Group dismissed Hindenburg’s allegations as a "deliberate assault" on India. Hindenburg reaffirmed its conclusions and invited legal action from the conglomerate. These claims led MSCI to downgrade the free-float status of four Adani entities and prompted Moody's to lower their ratings outlook. Additionally, Credit Suisse stopped accepting Adani bonds as collateral for margin lending.
The Securities and Exchange Board of India (SEBI) issued a show cause notice to Hindenburg accusing it of utilizing insider information to short Adani shares and inciting market disruption. Hindenburg refuted these charges, characterizing SEBI’s move as an effort to suppress dissent and noting that its profits from short positions were minimal.
In August 2024, Hindenburg published another report alleging that SEBI chairperson Madhabi Puri Buch and her spouse held interests in offshore entities involved in artificially inflating Adani share prices. Both denied these claims as unfounded.
Claims of unlawful conduct involving Block
On March 23, 2023, Hindenburg revealed a short position in Block, which resulted in a 15% decline in the company’s stock price on that day. The firm accused Block of inflating user figures, inadequately preventing fraudulent and illegal activities on Cash App, and permitting impersonation of prominent individuals. The report asserted that Block had "adopted predatory products and poor compliance practices to drive growth and profit from enabling fraud against consumers and government entities." Block refuted these accusations and stated it was considering pursuing legal action against Hindenburg.
In May 2024, NBC News reported that prosecutors from the Southern District of New York were examining Block’s financial transactions and internal operations, concentrating on alleged compliance lapses within its Square and Cash App divisions. The company faced allegations of insufficient customer data collection, processing payments involving sanctioned nations, and managing cryptocurrency transactions linked to terrorist organizations.
By November 2024, Block revealed in its third-quarter earnings statement that it was in discussions to potentially settle with multiple state regulators concerning its anti-money laundering efforts. Simultaneously, negotiations were underway with the Consumer Financial Protection Bureau (CFPB) addressing Cash App’s handling of customer complaints and dispute resolution. Block acknowledged accruing liabilities related to these possible settlements but noted that these amounts were not significant enough to impact its financial results as of September 30, 2024.
Icahn Enterprises analysis
In May 2023, Hindenburg published a report on Icahn Enterprises, which saw its share price fall by more than half following the disclosure of Hindenburg’s short position. The report characterized Icahn Enterprises’ dividend mechanism as "ponzi-like" and criticized research by Jefferies Group as "among the most egregious examples of sell-side research malpractice."
Additional analyses
Hindenburg has also scrutinized companies such as online gambling operator DraftKings,[1] geothermal energy provider Ormat Technologies,[2] electric vehicle manufacturer Mullen Technologies,[3] and Chinese blockchain and cryptocurrency mining firm SOS.[4]
In March 2023, Hindenburg accused Block, under the leadership of Jack Dorsey, of exaggerating user statistics, enabling illicit activities, and being subject to a potential SEC probe. This led to a 22% plunge in the stock price before some recovery.
In June 2023, Hindenburg alleged widespread fraud at Tingo Group, including falsified founder credentials, dubious financial statements, and fabricated partnerships. Following this report, Tingo’s shares listed on NASDAQ experienced a steep decline. The company dismissed the allegations as "misleading and defamatory" and retained White & Case for legal assessment.
In August 2023, Hindenburg’s investigation into Freedom Holding triggered an inquiry by the U.S. Department of Justice. In August 2024, Hindenburg disclosed a short position in Supermicro, citing accounting concerns described as "red flags." Subsequently, Supermicro postponed filing its annual report, causing its share price to fall over 25%. A preliminary DOJ investigation commenced a month later. In October 2024, auditor Ernst & Young resigned due to worries about internal controls, board independence, and accounting procedures, resulting in Supermicro losing approximately one-third of its market value.
Other activities
In October 2021, Hindenburg announced a $1 million bounty seeking information about the mechanism behind the Tether cryptocurrency's peg to the U.S. dollar, as well as details regarding Tether's deposit holdings, emphasizing that they did not possess any cryptocurrency positions at that point.
In May 2022, after Elon Musk revealed plans to acquire Twitter, Hindenburg initiated a short position on Twitter shares. When Musk attempted to back out of the agreement, Hindenburg reversed course and took a substantial long position, anticipating the deal would ultimately be finalized.
