Washington has its eyes on the Netherlands, a small but important European country that could hold the key to China’s future in manufacturing cutting-edge semiconductors.

The Netherlands has a population of just more than 17 million people — but is also home to ASML, a star of the global semiconductor supply chain. It produces a high-tech chipmaking machine that China is keen to have access to.

The U.S. appears to have persuaded the Netherlands to prevent shipments to China for now, but relations look rocky as the Dutch weigh up their economic prospects if they’re cut off from the world’s second-largest economy.

ASML’s critical chip role

ASML, headquartered in the town of Veldhoven, does not make chips. Instead, it makes and sells $200 million extreme ultraviolet (EUV) lithography machines to semiconductor manufacturers like Taiwan’s TSMC.

These machines are required to make the most advanced chips in the world, and ASML has a de facto monopoly on them, because it’s the only company in the world to make them.

This makes ASML one of the most important chip companies in the world.

U.S.-Netherlands talks

U.S. pressure on the Netherlands appears to have begun in 2018 under the administration of former President Donald Trump. According to a Reuters report from 2020, the Dutch government withdrew ASML’s license to export its EUV machines to China after extensive lobbying from the U.S. government.

Under Trump, the U.S. started a trade war with China that morphed into a battle for tech supremacy, with Washington attempting to cut off critical technology supplies to Chinese companies.

Huawei, China’s telecommunications powerhouse, faced export restrictions that starved it of the chips it required to make smartphones and other products, crippling its mobile business. Trump also used an export blacklist to cut off China’s largest chipmaker, SMIC, from the U.S. technology sector.

President Joe Biden‘s administration has taken the assault on China’s chip industry one step further.

In October, the U.S. Department of Commerce’s Bureau of Industry and Security introduced sweeping rules requiring companies to apply for a license if they want to sell certain advanced computing semiconductors or related manufacturing equipment to China.

ASML told its U.S. staff to stop servicing Chinese clients after the introduction of these rules.

Pressure on the Netherlands to fall in line with U.S. rules continues. Alan Estevez, the undersecretary of commerce for industry and security at the U.S. Department of Commerce, and Tarun Chhabra, senior director for technology and national security at the U.S. National Security Council, reportedly spoke with Dutch officials this month.

“Now that the U.S. government has put unilateral end-use controls on U.S. companies, these controls would be futile from their perspective if China could get these machines from ASML or Tokyo Electron (Japan),” Pranay Kotasthane, chairperson of the high-tech geopolitics program at the Takshashila Institution, told CNBC.

“Hence the U.S. government would want to convert these unilateral controls into multilateral ones by getting countries such as the Netherlands, South Korea, and Japan on board.”

The National Security Council declined to comment when contacted by CNBC, while the Department of Commerce did not respond to a request for comment.

A spokesperson for the Netherlands’ Ministry of Foreign Affairs said it does not comment on visits by officials. The ministry did not reply to additional questions from CNBC.

Tensions

Last week, U.S. Secretary of State Antony Blinken hailed the “growing convergence in the approach to the challenges that China poses,” particularly with the European Union.

But the picture from the Netherlands does not appear as rosy.

“Obviously we are weighing our own interests, our national security interest is of utmost importance, obviously we have economic interests as you may understand and the geopolitical factor always plays a role as well,” Liesje Schreinemacher, minister for foreign trade and development cooperation of the Netherlands, said last week.

She added that Beijing is “an important trade partner.”

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.
