Herbalife: Bill Ackman's Billion-Dollar War

TL;DR: In 2012, billionaire hedge fund manager Bill Ackman publicly declared that the massive nutritional supplement company Herbalife was a global, illegal pyramid scheme. He placed a massive $1 billion "short" bet that the stock would crash to zero. However, his bitter billionaire rival, Carl Icahn, saw an opportunity to destroy Ackman. Icahn aggressively bought millions of Herbalife shares to force the price up, triggering a vicious, highly public "Short Squeeze." Ackman fought for five years, ultimately losing roughly $1 billion in one of the most spectacular and deeply personal billionaire feuds in Wall Street history.

Introduction: The "Pyramid Scheme" Accusation

Bill Ackman is the highly aggressive founder of Pershing Square Capital Management. He is an activist short-seller known for attacking companies he believes are fraudulent.

In December 2012, Ackman rented out an auditorium in Manhattan and gave a massive, 3-hour, 342-slide presentation. His target was Herbalife, a multi-level marketing (MLM) company that sold weight-loss shakes.

Ackman didn't just criticize the company's financials. He explicitly accused Herbalife of being a massive, illegal Pyramid Scheme.

He argued that Herbalife distributors didn't actually make money by selling protein shakes to real retail customers.
He argued they only made money by recruiting other desperate people into the scheme and forcing them to buy massive amounts of unsellable inventory.
He stated that Herbalife aggressively preyed on lower-income immigrant communities, ruining thousands of lives.

Ackman confidently announced to the world that his hedge fund had placed a massive $1 Billion short bet against Herbalife. His target price for the stock was $0.

The Feud: Carl Icahn Enters the War

Ackman's presentation was incredibly convincing. Herbalife's stock price immediately plummeted by 20%. Ackman was winning.

But then, Carl Icahn entered the arena. Icahn is a legendary, ruthless corporate raider. He also held a deep, intensely personal hatred for Bill Ackman stemming from a bitter lawsuit they fought a decade earlier over a real estate deal.

Icahn looked at Ackman's massive short position and realized that Ackman was highly vulnerable. If the stock price went up, Ackman would be forced to buy the stock at a loss to cover his short bet, causing him massive financial pain. Icahn didn't necessarily care about protein shakes. He just wanted to destroy Bill Ackman.

Icahn began aggressively buying millions of shares of Herbalife stock. He bought so much stock that he eventually owned 26% of the entire company.

The Short Squeeze and the Live TV Fight

Because Icahn was buying massive amounts of stock, the price violently reversed and started rocketing upwards. This triggered a Short Squeeze. Ackman was bleeding millions of dollars every week.

The feud escalated to unprecedented levels of public hostility. In January 2013, both billionaires called into live CNBC television at the same time. For 30 minutes, on national television, the two billionaires screamed at each other, trading deeply personal insults.

Icahn called Ackman a "crybaby in the schoolyard" and a "major loser."
Ackman called Icahn a "bully" and said he was "not used to someone standing up to him."

The FTC Investigation and the Surrender

Ackman refused to back down. He spent the next five years aggressively lobbying the US Government to shut Herbalife down, spending millions on PR campaigns, hiring private investigators, and lobbying Congress.

In 2016, his lobbying actually worked. The Federal Trade Commission (FTC) officially investigated Herbalife. The FTC found that Herbalife's business practices were deeply deceptive and forced the company to completely restructure its business model and pay a $200 million fine to compensate victims.

However, the FTC stopped short of officially declaring it an illegal pyramid scheme. They did not shut the company down.

Conclusion

Because the company wasn't shut down, the stock price survived. By 2018, Ackman could no longer withstand the massive financial losses. He completely surrendered, closing his short position. Ackman lost an estimated $1 Billion on the crusade. Carl Icahn, having successfully orchestrated the squeeze, eventually sold his massive stake years later, making hundreds of millions in profit. The Herbalife war remains the ultimate example of how a Wall Street short thesis can be completely destroyed by the sheer gravitational pull of a rival billionaire's ego.
