New book by biographer Walter Isaacson explores the billionaire’s leadership style and ‘demon mode’
4 min
Simply put: Elon Musk can be a real jerk.
And that has probably helped and hurt him in business, according to a new biography by Walter Isaacson.
In “Elon Musk,” out Tuesday, Isaacson puts forth the idea of “demon mode” to explain the temperamental impulses behind some of the tycoon’s successes—and setbacks. But it isn’t just demon mode that has fuelled his rise. Isaacson details other teachable ways the billionaire’s methods have helped make him the world’s richest man.
Both sides of Musk are sure to become part of B-school lore for a new generation of would-be entrepreneurs and business managers picking and choosing which traits and tactics to emulate.
Isaacson had previously made the concept of the “reality distortion field” popular with his bestselling 2011 book about Apple co-founder Steve Jobs and his ability to bend perception to motivate others.
Demon mode was on display in 2018 as Musk struggled to ramp up production of Tesla’s Model 3 sedan, which nearly destroyed the electric-car company and which the CEO dubbed production hell.
That experience through hell, the book says, also helped Musk shape five commandments for how he wants problems solved by his workers across his companies, from rocket maker SpaceX to social-media platform X, formerly Twitter.
Musk, in the book, calls the framework for problem solving “the algorithm.” In short, Musk urges his employees to:
“His executives sometimes move their lips and mouth the words, like they would chant the liturgy along with their priest,” Isaacson wrote of Musk’s mantra.
In the book, Musk acknowledges he talks about the approach often. “I became a broken record on the algorithm,” Musk is quoted as saying. “But I think it’s helpful to say it to an annoying degree.”
The approach builds off a long-held method for problem solving touted by Musk called first principles, a reasoning that breaks tasks into their very basics without simply reverting to what has been done before.
“The algorithm is a five-step process for not only making good products and designing good products, but manufacturing them,” Isaacson said in an interview Monday.
“It begins with first principles. He says, question every requirement, and, by first principles he means, look down at the physics. If somebody says, no, we can’t build it at this price, he says, tell me how much the materials cost. Tell me exactly what’s involved here and then tell me you can or can’t do it.”
There are other lessons in the book that Musk has long practiced, such as never asking an employee to do something you aren’t willing to do (hence his sleeping on factory floors), hiring employees based on their attitude, and saying “it’s OK to be wrong. Just don’t be confident and wrong.”
Telling Musk bad news, however, has been seen by some employees as dangerous to one’s career.
“One of his problems is people sometimes are afraid to tell him the bad news,” Isaacson said. “Those who succeed around Musk are those who figure out you got to give him the bad news even if it’s going to result in some unpleasant scenes.”
Their fear is often rooted in demon mode.
Claire Boucher, known as the musician Grimes and the mother of three of Musk’s children, coined the term in an interview with Isaacson.
“Demon mode is when he goes dark and retreats inside the storm in his brain,” Boucher said in the book. “Demon mode,” she added, “causes a lot of chaos but it also gets s— done.”
And Musk has gotten a lot done, helping usher in the electric-car era as Tesla chief executive and igniting the commercial space race with SpaceX, which he founded. His messy stewardship of X, however, is testing public perception of his business genius.
Isaacson, who shadowed Musk for two years in reporting the book, saw demon mode in person several times along with other personalities that he described as ranging from silly to charming. He suggests the roots of the dark clouds come from the 52-year-old’s childhood in South Africa.
“It’s almost like Dr. Jekyll and Mr. Hyde where a cloud comes over and he gets into a trance and he can just be tough in a cold way,” Isaacson said. “He never gets really angry, never gets that physical, but coldly brutal to people and he almost doesn’t remember afterwards what he’s done. Sometimes I’ll say, why did you say that to that person? And he’ll look at me blankly as if he didn’t quite remember what happened while he was in demon mode.”
In one instance, Isaacson described seeing demon mode emerge when Musk saw SpaceX’s launchpad in South Texas empty late one evening.
“He orders a hundred people to come in from different parts of SpaceX from Florida, California so they can all work for 24 hours a day getting this thing done even though there was no need to,” Isaacson said.
Such surges seem to play in tandem to Musk’s need for drama.
“He is a drama magnet,” Musk’s younger brother, Kimbal, said in the book. “That’s his compulsion, the theme of his life.”
Isaacson cautions that readers shouldn’t come away thinking they can be just like Musk and automatically succeed. Rather, he said, readers should see both how leaders such as Musk and the late Jobs were effective and also take away cautionary tales.
“You don’t have to be this mean,” he said.
Still, throughout his book, Isaacson chases the question of whether Musk could be successful any other way.
“I try to show how that’s one of the strands in a fabric and as Shakespeare said, we’re molded out of our faults,” Isaacson said. “If we pull that strand out, you might not get the whole cloth of Elon Musk.”

Selloff in bitcoin and other digital tokens hits crypto-treasury companies.
3 min
The hottest crypto trade has turned cold. Some investors are saying “told you so,” while others are doubling down.
It was the move to make for much of the year: Sell shares or borrow money, then plough the cash into bitcoin, ether and other cryptocurrencies. Investors bid up shares of these “crypto-treasury” companies, seeing them as a way to turbocharge wagers on the volatile crypto market.
Michael Saylor pioneered the move in 2020 when he transformed a tiny software company, then called MicroStrategy , into a bitcoin whale now known as Strategy. But with bitcoin and ether prices now tumbling, so are shares in Strategy and its copycats. Strategy was worth around $128 billion at its peak in July; it is now worth about $70 billion.
The selloff is hitting big-name investors, including Peter Thiel, the famed venture capitalist who has backed multiple crypto-treasury companies, as well as individuals who followed evangelists into these stocks.
Saylor, for his part, has remained characteristically bullish, taking to social media to declare that bitcoin is on sale. Sceptics have been anticipating the pullback, given that crypto treasuries often trade at a premium to the underlying value of the tokens they hold.
“The whole concept makes no sense to me. You are just paying $2 for a one-dollar bill,” said Brent Donnelly, president of Spectra Markets. “Eventually those premiums will compress.”
When they first appeared, crypto-treasury companies also gave institutional investors who previously couldn’t easily access crypto a way to invest. Crypto exchange-traded funds that became available over the past two years now offer the same solution.
BitMine Immersion Technologies , a big ether-treasury company backed by Thiel and run by veteran Wall Street strategist Tom Lee , is down more than 30% over the past month.
ETHZilla , which transformed itself from a biotech company to an ether treasury and counts Thiel as an investor, is down 23% in a month.
Crypto prices rallied for much of the year, driven by the crypto-friendly Trump administration. The frenzy around crypto treasuries further boosted token prices. But the bullish run abruptly ended on Oct. 10, when President Trump’s surprise tariff announcement against China triggered a selloff.
A record-long government shutdown and uncertainty surrounding Federal Reserve monetary policy also have weighed on prices.
Bitcoin prices have fallen 15% in the past month. Strategy is off 26% over that same period, while Matthew Tuttle’s related ETF—MSTU—which aims for a return that is twice that of Strategy, has fallen 50%.
“Digital asset treasury companies are basically leveraged crypto assets, so when crypto falls, they will fall more,” Tuttle said. “Bitcoin has shown that it’s not going anywhere and that you get rewarded for buying the dips.”
At least one big-name investor is adjusting his portfolio after the tumble of these shares. Jim Chanos , who closed his hedge funds in 2023 but still trades his own money and advises clients, had been shorting Strategy and buying bitcoin, arguing that it made little sense for investors to pay up for Saylor’s company when they can buy bitcoin on their own. On Friday, he told clients it was time to unwind that trade.
Crypto-treasury stocks remain overpriced, he said in an interview on Sunday, partly because their shares retain a higher value than the crypto these companies hold, but the levels are no longer exorbitant. “The thesis has largely played out,” he wrote to clients.
Many of the companies that raised cash to buy cryptocurrencies are unlikely to face short-term crises as long as their crypto holdings retain value. Some have raised so much money that they are still sitting on a lot of cash they can use to buy crypto at lower prices or even acquire rivals.
But companies facing losses will find it challenging to sell new shares to buy more cryptocurrencies, analysts say, potentially putting pressure on crypto prices while raising questions about the business models of these companies.
“A lot of them are stuck,” said Matt Cole, the chief executive officer of Strive, a bitcoin-treasury company. Strive raised money earlier this year to buy bitcoin at an average price more than 10% above its current level.
Strive’s shares have tumbled 28% in the past month. He said Strive is well-positioned to “ride out the volatility” because it recently raised money with preferred shares instead of debt.
Cole Grinde, a 29-year-old investor in Seattle, purchased about $100,000 worth of BitMine at about $45 a share when it started stockpiling ether earlier this year. He has lost about $10,000 on the investment so far.
Nonetheless, Grinde, a beverage-industry salesman, says he’s increasing his stake. He sells BitMine options to help offset losses. He attributes his conviction in the company to the growing popularity of the Ethereum blockchain—the network that issues the ether token—and Lee’s influence.
“I think his network and his pizzazz have helped the stock skyrocket since he took over,” he said of Lee, who spent 15 years at JPMorgan Chase, is a managing partner at Fundstrat Global Advisors and a frequent business-television commentator.
