In January 2023, a U.S.-based firm known for exposing financial wrongdoing made headlines across the world with a fiery report. Hindenburg Research, named after the airship that famously caught fire in 1937, accused one of India’s biggest companies — the Adani Group — of serious financial misconduct. The report called Adani’s empire “the largest con in corporate history.”
The impact was instant. Shares of Adani Group companies crashed, wiping out over $150 billion in market value at one point. A record-breaking public offering from the company was also cancelled. For a brief moment, it looked like Gautam Adani, the billionaire industrialist behind the group, might lose everything.
But instead of panicking, Adani went into strategic mode — setting off what would later be known as “Operation Zeppelin”, a counter-effort as bold and dramatic as the attack itself.
The Shadow of a Scandal
The timing of the Hindenburg report raised eyebrows. It came just a week before Adani was scheduled to finalize a $1.2 billion deal to take over the Haifa Port in Israel, a key part of that country’s infrastructure strategy. The deal was historic — 18 global companies had shown interest, but only five made it to the final stage. In the end, a joint bid by Adani Ports and Gadot Masofim won.
The final signing took place on January 31, 2023, with Israeli Prime Minister Benjamin Netanyahu in attendance. But while the world focused on the Hindenburg controversy, something important happened behind closed doors in a quiet room at the Haifa port.
Sources say a top Israeli official asked Adani directly about the allegations. He responded firmly, calling them “absolute lies.” Also present in the meeting, reportedly, was Eshel Armoni, the outgoing port chairman and a former senior Mossad officer.
Some in Israel saw the report not as a financial investigation but as a political move — an attempt to disrupt the port deal, which Israel saw as crucial to the India-Middle East-Europe Economic Corridor, a strategic alternative to China’s growing regional influence.
How Adani Fought Back
Back in India, Adani quickly moved to rebuild investor confidence. He reduced debt by repaying loans early, cut down on shares pledged as collateral, brought in new equity from promoters and top-tier investors, and focused on the core strengths of the group.
At the same time, something much more secretive was unfolding.
Enter Operation Zeppelin
Behind the scenes, Adani’s team had begun a covert investigation, reportedly involving help from an Israeli intelligence agency. According to sources, the goal was to find out who was really behind the Hindenburg attack.
Surveillance began around Hindenburg’s offices in New York. The firm’s founder, Nathan ‘Nate’ Anderson, a certified financial analyst, also came under scrutiny. Investigators started uncovering a network of activist lawyers, hedge funds, journalists, and political influencers, some of whom were allegedly linked to Chinese interests or powerful figures in Washington.
One key breakthrough came in Oakbrook Terrace, a suburb outside Chicago, where encrypted messages were discovered connecting private asset firms with activists across India, the U.S., Europe, Canada, and Australia.
In January 2024, Adani was personally briefed on the covert operation during a trip to Switzerland.
Building a Legal and Cyber Arsenal
Adani’s response was methodical, not loud. He assembled a team of attorneys, intelligence experts, and cyber specialists. In Ahmedabad, a tech-heavy command center was set up to track digital trails and gather data. Legal teams worked across capitals — from New Delhi to New York — piecing together a global counteroffensive.
By October 2024, the effort had produced a 353-page dossier, reportedly filled with information on those allegedly involved in the anti-Adani campaign. Some leaked documents hinted at ties between U.S. agencies and media platforms that were pushing the Hindenburg story.
Then, in November 2024, a new twist emerged — the U.S. Department of Justice and the Securities and Exchange Commission (SEC) charged Gautam Adani and other top officials with being part of an alleged bribery scheme to secure green energy contracts in India. The Adani Group denied all charges.
Legal Battlelines Drawn
Despite the fresh legal trouble, the Adani Group decided to go on the offensive. It began preparing a lawsuit in New York against Hindenburg and Nate Anderson. A seven-page legal brief was reportedly sent to Hindenburg’s office at 295 Fifth Avenue in Manhattan. Sources say a meeting between Adani’s legal team and Hindenburg was proposed, but it’s unclear if it ever happened.
The Final Twist: Hindenburg Shuts Down
In a dramatic turn, on January 15, 2025, just days before the second anniversary of its report, Hindenburg Research announced it was shutting down.
Though much of Operation Zeppelin remains under wraps, what’s known is enough to make it one of the boldest corporate counter-strikes in modern business history. It was a campaign of strategy, surveillance, diplomacy, and cyber intelligence — one that helped Adani rise from the brink of collapse to reclaim his footing on the global stage.
