Artificial intelligence takes a lot of compute power, and Microsoft is putting together a road map for powering that computation with small nuclear reactors.

That’s according to a job description Microsoft posted Thursday seeking a nuclear technology expert to lead the company’s technical assessment for integrating small modular nuclear reactors and microreactors “to power the datacenters that the Microsoft Cloud and AI reside on,” the job posting reads.

Specifically, Microsoft is looking to hire a “principal program manager for nuclear technology” and that person “will be responsible for maturing and implementing a global Small Modular Reactor (SMR) and microreactor energy strategy,” the job posting reads. Microsoft is looking to generate energy with nuclear fission, which is when an atom splits and releases energy that as a result of that splitting.

In January, Microsoft announced a multiyear, multibillion-dollar investment in OpenAI, maker of viral AI chatbot ChatGPT. Bill Gates, Microsoft’s co-founder, is also the chairman of the board of TerraPower, a nuclear innovation company in the process of developing and scaling small modular reactor designs.

TerraPower “does not currently have any agreements to sell reactors to Microsoft,” a spokesperson told CNBC.

However, Microsoft has publicly committed to pursuing nuclear energy from an innovator in the fusion space.

In May, Microsoft announced it signed a power purchase agreement with Helion, a nuclear fusion startup, to buy electricity from it in 2028. Sam Altman, CEO of OpenAI, is an early and significant investor in Helion.

Nuclear fusion occurs when two smaller atomic nuclei smash together to form a heavier atom and release tremendous quantities of energy in the process. It is the way in which the sun makes power. Fusion has not yet been recreated at scale here on earth, but many venture-backed startups are working to make it a reality due to the potential promise of virtually unlimited clean energy.

Interest in nuclear energy has increased alongside concerns about climate change in recent years, as nuclear reactors generate electricity without releasing virtually any carbon dioxide emissions.

The existing fleet of nuclear reactors in the United States were largely built between 1970 and 1990, and currently generate about 18% of the total electricity in the United States, according to the U.S. Energy Information Administration. Nuclear energy also makes up 47% of America’s carbon-free electricity in 2022, according to the U.S. Department of Energy.

Much of the hope for the next generation of nuclear reactor technology in the United States is pinned on smaller nuclear reactors, which Microsoft’s job posting indicates the company is interested in using to power its data centers.

Small nuclear reactors are, as the name suggests, smaller than conventional reactors and cheaper and quicker to build, since they’re designed with modular construction and not every piece of the reactor needs a bespoke manufacturing process. One primary criticism of the nuclear industry is that building reactors has come to require excessive time and money.

Nvidia positioned to weather Trump tariffs, chip demand ‘off the charts,’ says Altimeter’s Gerstner

Nvidia positioned to weather Trump tariffs, chip demand 'off the charts,' says Altimeter's Gerstner

Altimeter CEO Brad Gerstner is buying Nvidia

Altimeter Capital CEO Brad Gerstner said Thursday that he’s moving out of the “bomb shelter” with Nvidia and into a position of safety, expecting that the chipmaker is positioned to withstand President Donald Trump’s widespread tariffs.

“The growth and the demand for GPUs is off the charts,” he told CNBC’s “Fast Money Halftime Report,” referring to Nvidia’s graphics processing units that are powering the artificial intelligence boom. He said investors just need to listen to commentary from OpenAI, Google and Elon Musk.

President Trump announced an expansive and aggressive “reciprocal tariff” policy in a ceremony at the White House on Wednesday. The plan established a 10% baseline tariff, though many countries like China, Vietnam and Taiwan are subject to steeper rates. The announcement sent stocks tumbling on Thursday, with the tech-heavy Nasdaq down more than 5%, headed for its worst day since 2022.

The big reason Nvidia may be better positioned to withstand Trump’s tariff hikes is because semiconductors are on the list of exceptions, which Gerstner called a “wise exception” due to the importance of AI.

Nvidia’s business has exploded since the release of OpenAI’s ChatGPT in 2022, and annual revenue has more than doubled in each of the past two fiscal years. After a massive rally, Nvidia’s stock price has dropped by more than 20% this year and was down almost 7% on Thursday.

Gerstner is concerned about the potential of a recession due to the tariffs, but is relatively bullish on Nvidia, and said the “negative impact from tariffs will be much less than in other areas.”

He said it’s key for the U.S. to stay competitive in AI. And while the company’s chips are designed domestically, they’re manufactured in Taiwan “because they can’t be fabricated in the U.S.” Higher tariffs would punish companies like Meta and Microsoft, he said.

“We’re in a global race in AI,” Gerstner said. “We can’t hamper our ability to win that race.”

YouTube announces Shorts editing features amid potential TikTok ban

YouTube on Thursday announced new video creation tools for Shorts, its short-form video feed that competes against TikTok. 

The features come at a time when TikTok, which is owned by Chinese company ByteDance, is at risk of an effective ban in the U.S. if it’s not sold to an American owner by April 5.

Among the new tools is an updated video editor that allows creators to make precise adjustments and edits, a feature that automatically syncs video cuts to the beat of a song and AI stickers.

The creator tools will become available later this spring, said YouTube, which is owned by Google

Along with the new features, YouTube last week said it was changing the way view counts are tabulated on Shorts. Under the new guidelines, Shorts views will count the number of times the video is played or replayed with no minimum watch time requirement. 

Previously, views were only counted if a video was played for a certain number of seconds. This new tabulation method is similar to how views are counted on TikTok and Meta’s Reels, and will likely inflate view counts.

“We got this feedback from creators that this is what they wanted. It’s a way for them to better understand when their Shorts have been seen,” YouTube Chief Product Officer Johanna Voolich said in a YouTube video. “It’s useful for creators who post across multiple platforms.”

Technology stocks plummeted Thursday after President Donald Trump’s new tariff policies sparked widespread market panic.

Apple led the declines among the so-called “Magnificent Seven” group, dropping nearly 9%. The iPhone maker makes its devices in China and other Asian countries. The stock is on pace for its steepest drop since 2020.

Other megacaps also felt the pressure. Meta Platforms and Amazon fell more than 7% each, while Nvidia and Tesla slumped more than 5%. Nvidia builds its new chips in Taiwan and relies on Mexico for assembling its artificial intelligence systems. Microsoft and Alphabet both fell about 2%.

Semiconductor stocks also felt the pain, with Marvell Technology, Arm Holdings and Micron Technology falling more than 8% each. Broadcom and Lam Research dropped 6%, while Advanced Micro Devices declined more than 4% Software stocks ServiceNow and Fortinet fell more than 5% each.

The drop in technology stocks came amid a broader market selloff spurred by fears of a global trade war after Trump unveiled a blanket 10% tariff on all imported goods and a range of higher duties targeting specific countries after the bell Wednesday. He said the new tariffs would be a “declaration of economic independence” for the U.S.

Companies and countries worldwide have already begun responding to the wide-sweeping policy, which included a 34% tariff on China stacked on a previous 20% tax, a 46% duty on Vietnam and a 20% levy on imports from the European Union.

China’s Ministry of Commerce urged the U.S. to “immediately cancel” the unilateral tariff measures and said it would take “resolute counter-measures.”

The tariffs come on the heels of a rough quarter for the tech-heavy Nasdaq and the worst period for the index since 2022. Stocks across the board have come under pressure over concerns of a weakening U.S. economy. The Nasdaq Composite dropped nearly 5% on Thursday, bringing its year-to-date loss to 13%.

Trump applauded some megacap technology companies for investing money into the U.S. during his speech, calling attention to Apple’s plan to spend $500 billion over the next four years.
