Super Micro Computer joined the Nasdaq 100 in July. Five months later, it’s out, and the stock is down 7% on the news.

Nasdaq said late Friday that Super Micro is being removed from the index, which is made up of the top 100 non-financial stocks on the Nasdaq and is the basis for the Invesco QQQ Trust exchange-traded fund, one of the most actively traded ETFs.

The announcement is the latest in a roller coaster of a year for Super Micro, which rocketed to a record high of $118.81 in March, as demand soared for the company’s servers packed with artificial intelligence processors. The company’s market cap reached over $70 billion, high enough to merit inclusion in the S&P 500.

Super Micro is now worth about $20 billion, about a quarter the size of the median market cap of companies in the Nasdaq 100. Nasdaq will also remove Illumina and Moderna from the group, effective Dec. 23.

The revision will make room for the additions of Axon Enterprise and Palantir Technologies, as well as MicroStrategy, a company whose value is tied to its billions of dollars worth of bitcoin purchases. MicroStrategy shares have gained almost 600% so far this year and were up 4% on Monday.

For Super Micro, the story started to turn in August, when the company said it wouldn’t file its annual report with the SEC on time. Noted short seller Hindenburg Research then disclosed a short position in the company, and said in a report that it identified “fresh evidence of accounting manipulation.”

In October, Ernst & Young resigned as Super Micro’s auditor, resulting in a 33% stock plunge. An independent special board committee evaluated concerns from Ernst & Young and found no misconduct following a three-month investigation. The report recommended the company replace its CFO. The company said in November that BDO was its new auditor.

Super Micro was at risk of being delisted from Nasdaq altogether for a second time because of its delayed financial reports, but two weeks ago it received an extension until February 2025.

In a preliminary earnings report, the company said revenue for the third quarter was up 181% year over year, below consensus.

“Competition is strong, but I believe we are in good position,” CEO Charlies Liang said during a November conference call with analysts. Rivals include Dell and HPE.

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 rises to fresh record above 2,000, helped by Nvidia-led tech rally

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

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.
