High-performance memory chips are likely to remain in tight supply this year, as explosive AI demand drives a shortage for these chips, according to analysts.

SK Hynix and Micron – two of the world’s largest memory chip suppliers – are out of high-bandwidth memory chips for 2024, while the stock for 2025 is also nearly sold out, according to the firms.

“We expect the general memory supply to remain tight throughout 2024,” Kazunori Ito, director of equity research at Morningstar said in a report last week.

The demand for AI chipsets has boosted the high-end memory chip market, hugely benefiting firms such Samsung Electronics and SK Hynix, the top two memory chipmakers in the world. While SK Hynix already supplies chips to Nvidia, the company is reportedly considering Samsung as a potential supplier too.

High-performance memory chips play a crucial role in the training of large language models (LLMs) such as OpenAI’s ChatGPT, which led AI adoption to skyrocket. LLMs need these chips to remember details from past conversations with users and their preferences to generate human-like responses to queries.

“The manufacturing of these chips are more complex and ramping up production has been difficult. This likely sets up shortages through the rest of 2024 and through much of 2025,” said William Bailey, director at Nasdaq IR Intelligence.

HBM’s production cycle is longer by 1.5 to 2 months compared with DDR5 memory chip commonly found in personal computers and servers, market intelligence firm TrendForce said in March.

To meet soaring demand, SK Hynix plans to expand production capacity by investing in advanced packaging facilities in Indiana, U.S. as well as in the M15X fab in Cheongju and the Yongin semiconductor cluster in South Korea.

Samsung during its first-quarter earnings call in April said its HBM bit supply in 2024 “expanded by more than threefold versus last year.” Chip capacity refers to the number of bits of data a memory chip can store.

“And we have already completed discussions with our customers with that committed supply. In 2025, we will continue to expand supply by at least two times or more year on year, and we’re already in smooth talks with our customers on that supply,” Samsung said.

Micron didn’t respond to CNBC’s request for comment.

Big Tech companies Microsoft, Amazon and Google are spending billions to train their own LLMs to stay competitive, fueling demand for AI chips.

“The big buyers of AI chips – firms like Meta and Microsoft – have signaled they plan to keep pouring resources into building AI infrastructure. This means they will be buying large volumes of AI chips, including HBM, at least through 2024,” said Chris Miller, author of “Chip War,” a book on the semiconductor industry.

Chipmakers are in a fierce race to manufacture the most advanced memory chips in the market to capture the AI boom.

SK Hynix in a press conference earlier this month said that it would begin mass production of its latest generation of HBM chips, the 12-layer HBM3E, in the third quarter, while Samsung Electronics plans to do so within the second quarter, having been the first in the industry to ship samples of the latest chip.

“Currently Samsung is ahead in 12-layer HBM3E sampling process. If they can get qualification earlier than its peers, I assume it can get majority shares in end-2024 and 2025,” said SK Kim, executive director and analyst at Daiwa Securities.

Venture capital firm Accel said Tuesday it’s raised $650 million for its eighth fund targeted at investing in European and Israeli early-stage startups, in a sign the venture capital market may be showing signs of a recovery.

The firm, which made prolific early bets on the likes of social media app Facebook and music streaming service Spotify, said in a press release it raised the fund to “support ambitious founders building global category-defining companies” in Europe and Israel.

Harry Nelis, general partner at Accel, said the European tech ecosystem in particular has evolved drastically in the nearly 25 years since it opened up its London office as a separate fund in 2001.

“The environment has dramatically changed since then,” Nelis told CNBC. “People would ask us, can Europe generate $1 billion outcomes?”

“Now, there are more than 360 venture-backed unicorns across Europe and Israel, and the whole ecosystem has evolved from one that raised about $1 billion in capital to now $66 billion in 2023.”

It comes after Plural, a venture capital firm established by the founders of Wise, Skype and Songkick, raised its own 400 million euros ($431 million) fund in January to back technology startups in Europe.

Climate-focused VC firm World Fund closed a 300 million euro fund in March.

Magnus Grimeland, CEO of seed investor Antler, told CNBC earlier this year that early-stage venture activity and private company valuations have been inching up since the start of this year — and he expects Europe to follow the trend.

“It’s on its way back,” Grimeland said in an interview at Antler’s London office in March. “We see a lot more activity in the portfolio. In New York, we made eight investments in January, and seven of them already have follow-on investments. The U.S. tends to always act quicker.”

The firm has previously invested in Synthesia, a $1 billion generative AI startup backed by U.S. chipmaker Nvidia that helps companies make presentations with AI-generated avatars.

Victor Riparbelli, CEO and co-founder of Synthesia, told CNBC his company partnered with Accel last year as the firm’s team knows “how to strike the right balance between visionary and useful technology.”

“Over the last year, there have been a lot of cool demos and perhaps too much frothiness in the AI industry,” Riparbelli told CNBC via email. “It was really important to us to partner with a fund that is as focussed as we are on delivering real, tangible business value.”

Anthropic, the artificial intelligence startup backed by Amazon, said Monday it’s launching its generative AI assistant Claude in Europe on Tuesday. It will be available to individuals and businesses through the web and via an iPhone app.

A paid subscription-based version of Anthropic’s Claude assistant, called Claude Pro, will be available to users who want access to all its models, including Claude 3 Opus, Anthropic’s most advanced offering.

Anthropic is also launching its business-focused Claude Team subscription-based plans, which cost 28 euros ($30) a month before value-added tax (VAT).

“We’ve designed Claude with a strong commitment to accuracy, security and privacy,” Dario Amodei, CEO and co-founder at Anthropic, said in a statement Tuesday.

AI has been advancing rapidly and officials are concerned about the impact on jobs and privacy.

The European Union Parliament earlier this year passed the world’s first major set of regulatory ground rules to govern the new technology. The AI Act seeks to, among other things, identify and apply rules in accordance with the levels of risk AI poses, dividing categories of risk into low, medium, high and unacceptable.

Anthropic said its Claude assistant is highly fluent in French, German, Italian, Spanish, and other European languages.

While Claude.ai is already available for free on both web and mobile in the U.K., Anthropic says this is the first time the product is launching for users in the EU and non-EU countries like Norway, Switzerland, and Iceland.

Anthropic has quickly become one of the buzziest and most-hyped generative AI companies in the market, with investors valuing the firm at a whopping $18.4 billion as recently as March. That month, Amazon announced a $2.75 billion investment in the startup, taking its total invested in the firm to date to $4 billion.

Amazon’s investment into Anthropic has attracted concerns from some regulators, who worry it could lessen the company’s independence.

In the United Kingdom, regulators are assessing whether Amazon’s investment and partnership with Anthropic, and deals struck by Microsoft with generative AI firms, may constitute effective mergers that could lessen competition.

Amazon says its partnership with Anthropic constitutes a limited corporate investment, not a merger. Microsoft denies its deals with AI startups OpenAI and Mistral and hiring from Inflection are equivalent to merging.
