Greatest Corporate Raids
16 battles scored on Impact, Returns, and Drama — each out of 10, totaling /30
TWA (Trans World Airlines)
1985The raid that made Icahn a household name. Launched a hostile takeover of TWA, won control, stripped assets, loaded debt, extracted hundreds of millions. Became the archetype of the 1980s corporate raider.
Texaco
1988Bought a massive stake during Texaco's bankruptcy following the Pennzoil verdict. Forced management changes. Extracted a $2 billion profit in months. Proved that bankruptcy was opportunity, not disaster.
RJR Nabisco
1989Entered the most famous leveraged buyout in history alongside KKR. The battle that inspired 'Barbarians at the Gate.' Icahn was one of several raiders circling — the feeding frenzy that defined an era.
Netflix
2012-2015Bought 10% of Netflix at ~$58/share when everyone thought streaming was dead. Rode the stock to $700+ before selling. Made $2 billion+ on a contrarian bet that changed how he was perceived — from raider to visionary.
Apple
2013-2016Took a $4.7 billion position and publicly pressured Tim Cook to return cash to shareholders. Demanded a $150 billion buyback. Apple ultimately returned $200 billion+. Icahn made $2 billion profit in 3 years.
Herbalife
2013-2018Took the opposite side of Bill Ackman's $1 billion short, buying 26% of Herbalife. The most public investor feud in history — screaming matches on live CNBC. Icahn won. Ackman lost $1 billion.
Xerox
2017-2021Gained control of Xerox's board and attempted a hostile takeover of HP Inc. — a company 3x Xerox's size. The audacity was staggering. HP resisted. COVID killed the deal. But the ambition was pure Icahn.
eBay
2014Demanded eBay spin off PayPal. Management resisted for months. Icahn was right. PayPal was spun off in 2015 and became worth more than eBay. Classic Icahn: saw the hidden value, forced the unlock.
Phillips Petroleum
1985Attempted hostile takeover of Phillips 66. Forced the company into a leveraged recapitalization that paid shareholders a massive premium. Made $75 million in greenmail. Bartlesville, Oklahoma still remembers.
Marvel Entertainment
1997Fought for control of bankrupt Marvel. The legal battle was vicious — Icahn vs. Ronald Perelman vs. bondholders. Eventually lost to Perelman but proved his willingness to fight in bankruptcy courts.
Motorola Solutions
2007-2011Pushed for the split of Motorola into two companies. Won board seats. Motorola Mobility was later sold to Google for $12.5 billion. The split unlocked massive value exactly as Icahn predicted.
Dell Technologies
2013Fought Michael Dell's $24.4 billion management buyout, arguing the price was too low. Lost the vote by a narrow margin. Dell went private, then public again at a much higher valuation — proving Icahn right.
Chesapeake Energy
2012-2013Forced out founder and CEO Aubrey McClendon after corporate governance scandals. Gained 4 board seats. Brought accountability to one of the most poorly governed companies in the energy sector.
Occidental Petroleum
2019-2020Opposed Occidental's $38 billion acquisition of Anadarko, calling it overpriced. Oil prices crashed. Icahn was proven right. Fought for board seats and accountability. The deal nearly destroyed Occidental.
Illumina
2023Waged a proxy fight to replace Illumina's entire board over the disastrous GRAIL acquisition. Won the fight. CEO was ousted. One of Icahn's most decisive recent victories — proof he's still dangerous at 87.
Blockbuster
2004-2010Took control of Blockbuster and tried to transform it. Too late. Netflix and streaming destroyed the model. One of Icahn's rare total losses — but he tried to fight the future head-on.

On the nature of activism
The Greatest Investor Feud
Icahn vs. Ackman — The Herbalife War
In December 2012, Bill Ackman of Pershing Square announced a $1 billion short position in Herbalife, calling it “the best-managed pyramid scheme in the history of the world.” It was the biggest public short in history.
Carl Icahn took the other side. He bought 26% of Herbalife, making it one of his largest positions. The stage was set for the most public investor feud Wall Street had ever seen.
On January 25, 2013, Icahn and Ackman had a legendary screaming match on live CNBC that lasted nearly 30 minutes. Icahn called Ackman “a liar” and “a crybaby.” Ackman called Icahn “a bully.” Scott Wapner tried to moderate. Nobody could look away.
The feud had personal history. Ackman had previously invested with Icahn, and their relationship ended in a lawsuit. This wasn't just about Herbalife — it was personal vendetta amplified by billions of dollars.
Carl Icahn — LONG
- Bought 26% of Herbalife
- Stock rose from $38 to $72+
- Made hundreds of millions
- Declared total victory on CNBC
Bill Ackman — SHORT
- $1 billion short position
- Held for 5 years
- Lost approximately $1 billion
- Called it his “worst investment”
The Herbalife war proved what everyone already knew: you don't bet against Carl Icahn. Especially when it's personal.
Investment Philosophy
The six pillars of Icahn's activist approach
Buy What Nobody Wants
Icahn targets deeply unloved companies — businesses where pessimism has compressed valuations below intrinsic value. The worse the sentiment, the bigger the opportunity.
Find Bad Management
A great business run by mediocre management is the ideal target. Icahn looks for companies where the board is asleep, the CEO is overpaid, and capital allocation is irrational.
Accumulate Quietly, Then Strike
Build a large position before anyone knows you're there. File the 13D. Then apply maximum pressure — public letters, proxy fights, media campaigns. The element of surprise is a weapon.
Force the Catalyst
Don't wait for the market to realize the value. Create the catalyst yourself — demand spinoffs, buybacks, management changes, asset sales, or outright acquisitions.
Use Leverage and Scale
Icahn doesn't take small positions. He takes stakes large enough to demand board seats, launch proxy fights, and threaten hostile takeovers. Size is influence.
Be Willing to Fight Forever
Most activists fold when management pushes back. Icahn doesn't fold. He escalates. The willingness to wage a multi-year war is what separates him from everyone else.
Market Phenomenon
The Icahn Lift
When Carl Icahn discloses a significant position in a company, the stock price almost always jumps — often dramatically. The market knows that Icahn's involvement means change is coming: buybacks, spinoffs, management shake-ups, or outright sales. This phenomenon is known as the Icahn Lift.

Major wins include Netflix ($2B+), Apple ($2B+), and Texaco ($2B+).

While Buffett buys great companies and holds forever, Icahn buys troubled companies and forces change. Buffett is patient capital; Icahn is a catalyst.
