The U.K. is set to hold its landmark artificial intelligence summit this week, as political leaders and regulators grow more and more concerned by the rapid advancement of the technology.
The two-day summit, which takes place on Nov. 1 and Nov. 2, will host government officials and companies from around the world, including the U.S. and China, two superpowers in the race to develop cutting-edge AI technologies.
It is Prime Minister Rishi Sunak’s chance to make a statement to the world on the U.K.’s role in the global conversation surrounding AI, and how the technology should be regulated.
Ever since the introduction of Microsoft-backed OpenAI’s ChatGPT, the race toward the regulation of AI from global policymakers has intensified.
Of particular concern is the potential for the technology to replace — or undermine — human intelligence.
Where it’s being held
The AI summit will be held in Bletchley Park, the historic landmark around 55 miles north of London.
Bletchley Park was a codebreaking facility during World War II.

It’s the location where, in 1941, a group of codebreakers led by British scientist and mathematician Alan Turing cracked Nazi Germany’s notorious Enigma machine.
It’s also no secret that the U.K. is holding the summit at Bletchley Park because of the site’s historical significance — it sends a clear message that the U.K. wants to reinforce its position as a global leader in innovation.
What it seeks to address
The main objective of the U.K. AI summit is to find some level of international coordination when it comes to agreeing some principles on the ethical and responsible development of AI models.
The summit is squarely focused on so-called “frontier AI” models — in other words, the advanced large language models, or LLMs, like those developed by companies such as OpenAI, Anthropic, and Cohere.
It will look to address two key categories of risk when it comes to AI: misuse and loss of control.
Misuse risks involve a bad actor being aided by new AI capabilities. For example, a cybercriminal could use AI to develop a new type of malware that cannot be detected by security researchers, or be used to help state actors develop dangerous bioweapons.
Loss of control risks refer to a situation in which the AI that humans create could be turned against them. This could “emerge from advanced systems that we would seek to be aligned with our values and intentions,” the government said.
Who’s going?
Major names in the technology and political world will be there.

When asked whether Sunak feels snubbed by his international counterparts, his spokesperson told reporters Monday, “No, not at all.”
“I think we remain confident that we have brought together the right group of world experts in the AI space, leading businesses and indeed world leaders and representatives who will be able to take on this vital issue,” the spokesperson said.
“This is the first AI safety summit of its kind and I think it is a significant achievement that for the first time people from across the world and indeed from across a range of world leaders and indeed AI experts are coming together to look at these frontier risks.”
Will it succeed?
The British government wants the AI Summit to serve as a platform to shape the technology’s future. It will emphasize safety, ethics, and responsible development of AI, while also calling for collaboration at a global level.
Sunak is hoping that the summit will provide a chance for Britain and its global counterparts to find some agreement on how best to develop AI safely and responsibly, and apply safeguards to the technology.
In a speech last week, the prime minister warned that AI “will bring a transformation as far reaching as the industrial revolution, the coming of electricity, or the birth of the internet” — while adding there are risks attached.
“In the most unlikely but extreme cases, there is even the risk that humanity could lose control of AI completely through the kind of AI sometimes referred to as super intelligence,” Sunak said.
Sunak announced the U.K. will set up the world’s first AI safety institute to evaluate and test new types of AI in order to understand the risks.
He also said he would seek to set up a global expert panel nominated by countries and organizations attending the AI summit this week, which would publish a state of AI science report.
A particular point of contention surrounding the summit is Sunak’s decision to invite China — which has been at the center of a geopolitical tussle over technology with the U.S. — to the summit. Sunak’s spokesperson has said it is important to invite China, as the country is a world leader in AI.
International coordination on a technology as complex and multifaceted as AI may prove difficult — and it is made all the more so when two of the big attendees, the U.S. and China, are engaged in a tense clash over technology and trade.

Washington recently curbed sales of Nvidia’s advanced A800 and H800 artificial intelligence chips to China.
Different governments have come up with their own respective proposals for regulating the technology to combat the risks it poses in terms of misinformation, privacy and bias.
The EU is hoping to finalize its AI Act, which is set to be one of the world’s first pieces of legislation targeted specifically at AI, by the end of the year, and adopt the regulation by early 2024 before the June European Parliament elections.
Some tech industry officials think that the summit is too limited in its focus. They say that, by keeping the summit restricted to only frontier AI models, it is a missed opportunity to encourage contributions from members of the tech community beyond frontier AI.
“I do think that by focusing just on frontier models, we’re basically missing a large piece of the jigsaw,” Sachin Dev Duggal, CEO of London-based AI startup Builder.ai, told CNBC in an interview last week.
“By focusing only on companies that are currently building frontier models and are leading that development right now, we’re also saying no one else can come and build the next generation of frontier models.”
Some are frustrated by the summit’s focus on “existential threats” surrounding artificial intelligence and think the government should address more pressing, immediate-term risks, such as the potential for deepfakes to manipulate 2024 elections.

“It’s like the fire brigade conference where they talk about dealing with a meteor strike that obliterates the country,” Stefan van Grieken, CEO of generative AI firm Cradle, told CNBC.
“We should be concentrating on the real fires that are literally present threats.”
However, Marc Warner, CEO of British AI startup Faculty.ai, said he believes that focusing on the long-term, potentially devastating risks of achieving artificial general intelligence to be “very reasonable.”
“I think that building artificial general intelligence will be possible, and I think if it is possible, there is no scientific reason that we know of right now to say that it’s guaranteed safe,” Warner told CNBC.
“In some ways, it’s sort of the dream scenario that governments tackle something before it’s a problem rather than waiting until stuff gets really bad.”

Among the thousands of Microsoft employees who lost their jobs in the cutbacks announced this week were 830 staffers in the company’s home state of Washington.
Nearly a dozen game design workers in the state were part of the layoffs, along with three audio designers, two mechanical engineers, one optical engineer and one lab technician, according to a document Microsoft submitted to Washington employment officials.
There were also five individual contributors and one manager at the Microsoft Research division in the cuts, as well as 10 lawyers and six hardware engineers, the document shows.
Microsoft announced plans on Wednesday to eliminate 9,000 jobs, as part of an effort to eliminate redundancy and to encourage employees to focus on more meaningful work by adopting new technologies, a person familiar with the matter told CNBC. The person asked not to be named while discussing private matters.
Scores of Microsoft salespeople and video game developers have since come forward on social media to announce their departure. In April, Microsoft said revenue from Xbox content and services grew 8%, trailing overall growth of 13%.
In sales, the company parted ways with 16 customer success account management staff members based in Washington, 28 in sales strategy enablement and another five in sales compensation. One Washington-based government affairs worker was also laid off.
Microsoft eliminated 17 jobs in cloud solution architecture in the state, according to the document. The company’s fastest revenue growth comes from Azure and other cloud services that customers buy based on usage.
CEO Satya Nadella has not publicly commented on the layoffs, and Microsoft didn’t immediately provide a comment about the cuts in Washington. On a conference call with analysts in April, Microsoft CFO Amy Hood said the company had a “focus on cost efficiencies” during the March quarter.

Nvidia’s Blackwell Ultra chips, the company’s next-generation graphics processor for artificial intelligence, have been commercially deployed at CoreWeave, the companies announced on Thursday.
CoreWeave has received shipments of Dell-built shipments based around Nvidia’s GB300 NVL72 AI systems, Dell said on Thursday. It’s the first cloud provider to install systems based around Blackwell Ultra.
The Blackwell Ultra is Nvidia’s latest chip, expected to ship in volume during the rest of the year. The systems that CoreWeave is installing are liquid-cooled and include 72 Blackwell Ultra GPUs and 36 Nvidia Grace CPUs. The systems are assembled and tested in the U.S., Dell said.
CoreWeave shares rose 6% during trading on Thursday, Dell shares were up about 2% and Nvidia rose less than 2%.
The announcement is a milestone for Nvidia.

AI developers still clamor for the latest Nvidia chips, which have improvements that make them better for training and deploying models.
Nvidia said Blackwell Ultra can produce 50 times more AI content than its predecessor, Blackwell.
Investors closely watch how Nvidia manages the transition when it announces new AI chips to see if there are production issues or delays. Nvidia CFO Colette Kress said in May that Blackwell Ultra shipments would start in the current quarter.
It’s also a win for CoreWeave, a cloud provider that rents access to Nvidia GPUs to other clouds and AI developers. Although CoreWeave is smaller than the cloud services operated by Amazon, Google, and Microsoft, its ability to offer Nvidia’s latest chips first give it a way to differentiate itself.
CoreWeave historically has a close relationship with Nvidia, which owns a stake in the cloud provider. CoreWeave went public earlier this year, and the stock price has quadrupled since its IPO.

For over three years, venture capital firms have been waiting for this moment.
Tech IPOs came to a virtual standstill in early 2022 due to soaring inflation and rising interest rates, while big acquisitions were mostly off the table as increased regulatory scrutiny in the U.S. and Europe turned away potential buyers.
Though it’s too soon to say those days are entirely in the past, the first half of 2025 showed signs of momentum, with June in particular producing much-needed returns for Silicon Valley’s startup financiers. In all, there were five tech IPOs last month, accelerating from a monthly average of two since January, according to data from CB Insights.
Highlighting that group was crypto company Circle, which more than doubled in its New York Stock Exchange debut on June 5, and is now up sixfold from its IPO price for a market cap of $42 billion. The stock got a big boost in mid-June after the Senate passed the GENIUS Act, which would establish a federal framework for U.S. dollar-pegged stablecoins.
Venture firms General Catalyst, Breyer Capital and Accel now own a combined $8 billion worth of Circle stock even after selling a fraction of their holdings in the offering. Silicon Valley stalwarts Greylock, Kleiner Perkins and Sequoia Capital are set to soon profit from Figma’s IPO, after the design software vendor filed its public prospectus on Tuesday. Since its $20 billion acquisition agreement with Adobe was scrapped in late 2023, Figma has been one of the most hotly anticipated IPOs in startup land.
It’s “refreshing and something that we’ve been waiting for for a long time,” said Eric Hippeau, managing partner at early-stage venture firm Lerer Hippeau, regarding the exit environment. “I’m not sure that we are confident that this can be a sustained trend yet, but it’s been very encouraging.”
Another positive sign for the industry the past couple months was the performance of artificial infrastructure provider CoreWeave, which went public in late March. The stock was relatively stagnant for its first month on the market but shot up 170% in May and another 47% in June.
For venture firms, long considered the lifeblood of risky tech startups, IPOs are essential in order to generate profits for the university endowments, foundations and pension funds that allocate a portion of their capital to the asset class. Without handsome returns, there’s little incentive for limited partners to put money into future funds.
After a record year in 2021, which saw 155 U.S. venture-backed IPOs raise $60.4 billion, according to data from University of Florida finance professor Jay Ritter, every year since has been relatively dismal. There were 13 such offerings in 2022, followed by 18 in 2023 and 30 last year, collectively raising $13.3 billion, Ritter’s data shows.
The slowdown followed the Federal Reserve’s aggressive rate-hiking campaign in 2022, meant to slow crippling inflation. As the lower-growth environment extended into years two and three, venture firms faced increasing pressure to return cash to investors.
‘Backlog of liquidity’
In its 2024 yearbook, the National Venture Capital Association said that even with a 34% increase in U.S. VC exit value last year to $98 billion, that number is 87% below the 2021 peak and less than half the average for the four years from 2017 through 2020. It’s a troubling dynamic for the 58,000 venture-backed companies that have raised a total of $947 billion from investors, according to the annual report, which is produced by the NVCA and PitchBook.
“This backlog of liquidity drought risks creating a ‘zombie company’ cohort — businesses generating operational cash flow but lacking credible exit prospects,” the report said.
Other than Circle, the latest crop of IPOs mostly consists of smaller and lesser-known brands. Health-tech companies Hinge Health and Omada Health are valued at about $3.5 billion and $1 billion, respectively. Etoro, an online trading platform, has a market cap of just over $5 billion. Online banking provider Chime Financial has a higher profile due largely to a years-long marketing blitz and is valued at close to $11.5 billion.
Meanwhile, the highest valued private companies like SpaceX, Stripe and Databricks remain on the sidelines, and AI highfliers OpenAI and Anthropic continue to raise massive amounts of cash with no intention of going public anytime soon.
Still, venture capitalists told CNBC that there are plenty of companies with the financial metrics to be public, and that more of them are readying for the process.
“The IPO market is starting to open and the VC world is cautiously optimistic,” said Rick Heitzmann, a partner at venture firm FirstMark in New York. “We are preparing companies for the next wave of public offerings.”
There are other ways to make money in the meantime. Secondary sales, a process that involves selling private shares to new investors, are on the rise, allowing early employees and investors to get some liquidity.

Last month, Meta announced a $14 billion bet on Scale AI, taking a 49% stake in the AI startup in exchange for poaching founder Alexandr Wang and a small group of his top engineers. The deal effectively bought out half of the stock owned by investors, leaving them with the opportunity to make money on the rest of their holdings, should a future acquisition or IPO take place.
The deal is a big win for Accel, which led Scale AI’s Series A round in 2017, and is poised to earn more than $2.5 billion in the transaction. Index Ventures led the Series B in 2018, and Peter Thiel’s Founders Fund led the Series C the following year at a valuation of over $1 billion.
Investors now hope the Federal Reserve will move toward a rate-cutting campaign, though the central bank hasn’t committed to one. There’s also ongoing optimism that regulators will make going public less burdensome. Last week, Reuters reported, citing sources familiar with the matter, that U.S. stock exchanges and the SEC have discussed loosening regulations to make IPOs more enticing.
Mike Bellin, who heads consulting firm PwC’s U.S. IPO practice, said he anticipates a diversity of IPOs across sectors in the second half of the year. According to data from PwC, pharma and fintech were among the most active sectors for deals through the end of May.
While the recent trend in IPO activity is an encouraging sign for investors, potential roadblocks remain.
Tariffs and geopolitical uncertainty delayed IPO plans from companies including Klarna and StubHub in April. Neither has provided an update on when they plan to debut.
FirstMark’s Heitzmann said the path forward is “not at all clear,” adding that he wants to see a strong quarter of economic stability and growth before confidently saying that the market is wide open.
Additionally, other than CoreWeave and Circle, recent tech IPOs haven’t had big pops. Hinge Health, Chime and eToro have seen relatively modest gains from their offer price, while Omada Health is down.
But virtually any activity beats what VCs were experiencing the last few years. Overall, Hippeau said recent IPO trends are generally encouraging.
“There’s starting to be kind of light at the end of the tunnel,” Hippeau said.
