Investors want Musk to be more involved with Tesla, says Loup’s Gene Munster

Twitter’s new owner and CEO, Elon Musk, posted an informal poll of the social media platform’s users Sunday asking if he should step down as head of the company.

At 6:20 a.m. ET on Monday, the poll ended with a majority of respondents (57.5%) calling for the billionaire to leave his post. More than 17 million users had voted by the time the poll closed.

Musk claimed he would abide by the results of the poll. It is unclear whether or not he will actually do so. Shares of Tesla — another one of Musk’s companies — were up more than 1% early Monday.

In court in November, Musk said, “I expect to reduce my time at Twitter and find somebody else to run Twitter over time.” However, on Sunday, he wrote in a tweet that there is no possible successor for him at the social media company.

“The question is not finding a CEO, the question is finding a CEO who can keep Twitter alive,” he wrote.

In response to another user speculating that Musk has already chosen a successor, the billionaire said: “No one wants the job who can actually keep Twitter alive. There is no successor.”

Twitter polls are straw polls, meaning they are informal and not comparable to professional public opinion research. Malicious bots or inauthentic accounts may also be able to register a response to a Twitter poll.

Musk’s Sunday poll followed online backlash after the “Chief Twit” (as he has called himself) made sudden changes to policies impacting users of Twitter in the last week.

For example, the company introduced a new social media platform promotion policy on Sunday, which prohibited users from sharing links to some of their other social media accounts. Longtime Musk friends and proponents, including Y Combinator founder Paul Graham, expressed their dismay at the policy causing Musk to later apologize and roll it back.

Days earlier, Twitter made changes to its policy on “doxxing,” which the company now defines as “sharing someone’s private information online without their permission.” The new policy prohibits users from sharing other people’s live location information, home addresses, contact information or physical location information but has left many confused over what information crosses Twitter’s line. 

Musk’s policy changes were used as a justification to suspend the Twitter accounts of a number of U.S.-based journalists, commentators and others who were critical of the CEO or his companies in the past. Some of the accounts were fully or partially restored a few days later, but not all.

The suspensions marked the latest chapter of Musk’s rocky takeover of Twitter. He led the acquisition of the company for around $44 billion in October, and his leadership has resulted in massive staff cuts, a spike in racist hate speech, advertisers fleeing or slashing their spending on the platform, as well as the reinstatement of previously banned accounts.

Musk claims that Twitter usage has reached an all-time high since he took over, and that hate speech impressions have fallen.

The billionaire’s management of Twitter is bleeding into, and raising concerns about, his other ventures.

For example, Musk has sold billions of dollars worth of Tesla shares this year to finance the Twitter takeover. He has also pulled in talent from both Tesla and SpaceX, including executives, engineers and attorneys, to assist him at Twitter.

A CEO spending time and money on Twitter isn’t Tesla’s only challenge — the company is currently offering discounts on vehicles in China, an indication of weaker demand for its cars there, according to Tesla bear Toni Sacconaghi of Bernstein on CNBC’s “Squawk on the Street” last week.

Earlier this month, NASA Administrator Bill Nelson asked SpaceX President and COO Gwynne Shotwell whether Musk’s “distraction” at Twitter might affect SpaceX’s work with the space agency, NBC News reported. Nelson said she reassured him it would not.

But Musk’s behavior at Twitter is having a negative impact on his car company’s public image and stock price. Shares in Tesla had dropped about 60% year to date as of Friday’s close. It comes amid a broad decline in growth stocks which has seen the tech-heavy Nasdaq Composite fall more than 30% year to date.

In a note late Sunday, Dan Ives, managing director of equities at Wedbush Securities, wrote that the second-biggest request on his Christmas “wish list” was for Musk to find a successor to run the social media company.

“With the Twitter chaos front and center and resulting in a major headache and overhang for the Tesla story, we believe Musk needs to name a permanent CEO of Twitter (and not Musk himself) to end the pain,” Ives said.

Tesla’s largest retail shareholder, Leo Koguan, wrote in a tweet on Dec. 14, that “Elon abandoned Tesla and Tesla has no working CEO.” He called on the company’s board of directors to take action. “Tesla needs and deserves to have [a] working full time CEO,” he wrote, criticizing the board for apparent inaction.

Musk tweeted last week that he will “make sure” Tesla shareholders benefit from Twitter in the long term.

A survey in Germany’s Der Spiegel last week found that 63% of respondents feel that Musk’s public performance as CEO of Twitter has had a mostly negative or clearly negative impact on their view of Tesla.

And only 9% of respondents to that survey said they find Tesla very or mostly likable as a brand — the company ranked far behind VW, BMW, Opel and others in Germany. That’s despite the fact that Tesla is investing heavily in the German market. It opened a major vehicle assembly plant in Grünheide, outside of Berlin, in March o this year.

Correction: This article has been updated to reflect that at 3.30 a.m. ET the majority of poll respondents had voted for Musk to leave his post.

Amazon Web Services is building equipment to cool Nvidia GPUs as AI boom accelerates

Amazon said Wednesday that its cloud division has developed hardware to cool down next-generation Nvidia graphics processing units that are used for artificial intelligence workloads.

Nvidia’s GPUs, which have powered the generative AI boom, require massive amounts of energy. That means companies using the processors need additional equipment to cool them down.

Amazon considered erecting data centers that could accommodate widespread liquid cooling to make the most of these power-hungry Nvidia GPUs. But that process would have taken too long, and commercially available equipment wouldn’t have worked, Dave Brown, vice president of compute and machine learning services at Amazon Web Services, said in a video posted to YouTube.

“They would take up too much data center floor space or increase water usage substantially,” Brown said. “And while some of these solutions could work for lower volumes at other providers, they simply wouldn’t be enough liquid-cooling capacity to support our scale.”

Rather, Amazon engineers conceived of the In-Row Heat Exchanger, or IRHX, that can be plugged into existing and new data centers. More traditional air cooling was sufficient for previous generations of Nvidia chips.

Customers can now access the AWS service as computing instances that go by the name P6e, Brown wrote in a blog post. The new systems accompany Nvidia’s design for dense computing power. Nvidia’s GB200 NVL72 packs a single rack with 72 Nvidia Blackwell GPUs that are wired together to train and run large AI models.

Computing clusters based on Nvidia’s GB200 NVL72 have previously been available through Microsoft or CoreWeave. AWS is the world’s largest supplier of cloud infrastructure.

Amazon has rolled out its own infrastructure hardware in the past. The company has custom chips for general-purpose computing and for AI, and designed its own storage servers and networking routers. In running homegrown hardware, Amazon depends less on third-party suppliers, which can benefit the company’s bottom line. In the first quarter, AWS delivered the widest operating margin since at least 2014, and the unit is responsible for most of Amazon’s net income.

Microsoft, the second largest cloud provider, has followed Amazon’s lead and made strides in chip development. In 2023, the company designed its own systems called Sidekicks to cool the Maia AI chips it developed.

Bitcoin hit a fresh record on Wednesday afternoon as an Nvidia-led rally in equities helped push the price of the cryptocurrency higher into the stock market close.

The price of bitcoin was last up 1.9%, trading at $110,947.49, according to Coin Metrics. Just before 4:00 p.m. ET, it hit a high of $112,052.24, surpassing its May 22 record of $111,999.

The flagship cryptocurrency has been trading in a tight range for several weeks despite billions of dollars flowing into bitcoin exchange traded funds. Bitcoin purchases by public companies outpaced ETF inflows in the second quarter. Still, bitcoin is up just 2% in the past month.

Bitcoin climbs above $112,000

On Wednesday, tech stocks rallied as Nvidia became the first company to briefly touch $4 trillion in market capitalization. In the same session, investors appeared to shrug off the latest tariff developments from President Donald Trump. The tech-heavy Nasdaq Composite notched a record close.

While institutions broadly have embraced bitcoin’s “digital gold” narrative, it is still a risk asset that rises and falls alongside stocks depending on what’s driving investor sentiment. When the market is in risk-on mode and investors buy growth-oriented assets like tech stocks, bitcoin and crypto tend to rally with them.

Investors have been expecting bitcoin to reach new records in the second half of the year as corporate treasuries accelerate their bitcoin buying sprees and Congress gets closer to passing crypto legislation.

Perplexity launches AI-powered web browser for select group of subscribers

Dado Ruvic | Reuters

Perplexity AI on Wednesday launched a new artificial intelligence-powered web browser called Comet in the startup’s latest effort to compete in the consumer internet market against companies like Google and Microsoft.

Comet will allow users to connect with enterprise applications like Slack and ask complex questions via voice and text, according to a brief demo video Perplexity released on Wednesday.

The browser is available to Perplexity Max subscribers, and the company said invite-only access will roll out to a waitlist over the summer. Perplexity Max costs users $200 per month.

“We built Comet to let the internet do what it has been begging to do: to amplify our intelligence,” Perplexity wrote in a blog post on Wednesday.

Perplexity is best known for its AI-powered search engine that gives users simple answers to questions and links out to the original source material on the web. After the company was accused of plagiarizing content from media outlets, it launched a revenue-sharing model with publishers last year.

In May, Perplexity was in late-stage talks to raise $500 million at a $14 billion valuation, a source familiar confirmed to CNBC. The startup was also approached by Meta earlier this year about a potential acquisition, but the companies did not finalize a deal.

“We will continue to launch new features and functionality for Comet, improve experiences based on your feedback, and focus relentlessly–as we always have–on building accurate and trustworthy AI that fuels human curiosity,” Perplexity said Wednesday.
