Britain’s anti-competition regulators have been tasked with investigating Microsoft and Amazon‘s dominance of the cloud computing market.
Media watchdog Ofcom on Thursday referred its inquiry for further investigation to the Competition and Markets Authority, kickstarting the process.
Ofcom said that it had identified features which make it more difficult for U.K. businesses to switch cloud providers, or use multiple cloud services, and that it is “particularly concerned” about the position of market leaders Amazon and Microsoft.
“Some UK businesses have told us they’re concerned about it being too difficult to switch or mix and match cloud provider, and it’s not clear that competition is working well,” Fergal Farragher, Ofcom’s director responsible for the market study, said in a statement Thursday.
“So, we’re referring the market to the CMA for further scrutiny, to make sure business customers continue to benefit from cloud services.”
Ofcom is concerned that so-called “hyperscalers” like Amazon Web Services and Microsoft Azure are limiting competition in the cloud computing market. These are companies that allow businesses of all stripes to carry out critical computing tasks — like storage and management of data, delivery of content, analytics and intelligence — over the internet, rather than through servers stored on site, or “on premise.”
AWS and Microsoft Azure are the biggest players in the market. AWS’ cloud solution is primarily targeted at startups, while Microsoft prioritizes big enterprises. AWS and Microsoft Azure account for roughly 60% to 70% of cloud spend, according to an Ofcom estimate. Combined, Amazon, Microsoft and Google generate roughly 81% of revenues in the U.K.’s cloud infrastructure services market, according to Ofcom, which estimates the market to be worth £15 billion ($18.2 billion).
The CMA probe comes amid the fast adoption of AI — cloud services, which are enabled by vast data centers, underpin many of the power-intensive generative AI models, such as OpenAI’s ChatGPT, Microsoft’s Bing Chat and Google’s Bard.
The Competition and Markets Authority said in a statement that it welcomes the Ofcom probe referral, adding that the cloud space “underpins a whole host of online services – from social media to AI foundation models.”
“Many businesses now completely rely on cloud services, making effective competition in this market essential,” Sarah Cardell, CEO of the CMA, said in a statement Thursday.
“Strong competition ensures a level playing field so that market power doesn’t end up in the hands of a few players – unlocking the full potential of these rapidly evolving digital markets so that people, businesses, and the UK economy can get the maximum benefits.”
The CMA’s independent inquiry group will now examine the market and identify what, if any, action should be taken. The CMA will conclude its investigation by April 2025.
Competition concerns
Ofcom, the agency responsible regulating technology, broadcast and telecom operations in the U.K., said that it identified a number of practices in the cloud industry that were of particular concern.
The regulator said that so-called “egress fees” charged by cloud vendors like Amazon and Microsoft make it tougher for businesses to move their data between providers, or to “multi-cloud” by using multiple cloud providers. Egress fees are charges for cloud companies to remove the data of firms from a cloud environment.
Ofcom also said that cloud companies have introduced “technical barriers” to interoperability — the ability of different cloud platforms and services to work together and exchange data without any barriers or disruptions. The authority said that this “makes it more difficult [for firms] to combine different services across cloud providers or to change provider.”
Lastly, Ofcom raised alarm bells over committed spend discounts, or incentives to give customers a discount if they spend a certain amount of money. While this can reduce customer costs, it also encourages companies to use a single cloud provider for all or most of their cloud needs, even when a cheaper alternative is available.
Competing cloud firms including Google, as well as regulators, have flagged concerns with Microsoft Azure, in particular — namely, allegedly unfair licensing terms that serve to “lock in clients,” keeping them attached to only Microsoft’s technology and making it harder to switch to other providers.
Microsoft’s cloud licensing terms are the subject of a separate European Union inquiry. The EU isn’t formally investigating Microsoft’s Azure cloud computing platform, but it has been assessing complaints from companies including France’s OVHCloud about Microsoft’s licensing terms.
A motorcycle is seen near a building of the Taiwan Semiconductor Manufacturing Company (TSMC), which is a Taiwanese multinational semiconductor contract manufacturing and design company, in Hsinchu, Taiwan, on April 16, 2025.
Here are TSMC’s first-quarter results versus LSEG consensus estimates:
Revenue: $839.25 billion New Taiwan dollars, vs. NT$835.13 billion expected
Net income: NT$361.56 billion, vs. NT$354.14 billion
TSMC’s reported net income increased 60.3% from a year ago to NT$361.56 billion, while net revenue in the March quarter rose 41.6% from a year earlier to NT$839.25 billion.
The world’s largest contract chip manufacturer has benefited from the AI boom as it produces advanced processors for clients such American chip designer Nvidia.
However, the company faces headwinds from the trade policy of U.S. President Donald Trump, who has placed broad trade tariffs on Taiwan and stricter export controls on TSMC clients Nvidia and AMD.
Semiconductor export controls could also be expanded next month under the “AI diffusion rules” first proposed by the Biden administration, further restricting the sales of chipmakers that use TSMC foundries.
Taiwan currently faces a blanket 10% tariff from the Trump administration and that could rise to 32% after the President’s 90-day pause of his “reciprocal tariffs” ends unless it reaches a deal with the U.S.
As part of efforts to diversify its supply chains, TSMC has been investing billions in overseas facilities, though the lion’s share of its manufacturing remains in Taiwan.
In an apparent response to Trump’s trade policy, TSMC last month announced plans to invest an additional $100 billion in the U.S. on top of the $65 billion it has committed to three plants in the U.S.
On Monday, AMD said it would soon manufacture processor chips at one of the new Arizona-based TSMC facilities, marking the first time that its chips will be manufactured in the U.S.
The same day, Nvidia announced that it has already started production of its Blackwell chips at TSMC’s Arizona plants. It plans to produce up to half a trillion dollars of AI infrastructure in the U.S. over the next four years through partners, including TSMC.
Taiwan-listed shares of TSMC were down about 0.4%. Shares have lost about 20% so far this year.

A day after Nvidia revealed it would incur $5.5 billion in costs related to canceled orders for the H20 chip, which the government said this week requires a license to export to China, the company said it abides by rules on where it can sell its artificial intelligence processors.
“The U.S. government instructs American businesses on what they can sell and where — we follow the government’s directions to the letter,” an Nvidia representative said in a statement.
Nvidia said the statement was in response to a House Select Committee focused on national security threats from China, which opened an investigation into Nvidia’s sales on Wednesday. The H20 was introduced by Nvidia after the Biden administration restricted AI chip exports in 2022. It’s a slowed-down version intended to comply with U.S. export controls.
Nvidia’s brief comment is an indication of how the company is going to defend its business in Washington, D.C., as its technology draws increased scrutiny related to national defense and security. The company’s stock price tumbled almost 7% on Wednesday.
Nvidia’s chips have the vast majority of the market for AI applications, and some were used by China’s DeepSeek to build R1, which upended markets in January.
On Wednesday, the chipmaker touted the taxes it paid, its U.S.-based workforce, and its role as a technology leader.
The company’s exports even help the U.S. fix its trade deficit, the statement said, directly addressing President Trump’s stated reason for introducing tariffs earlier this month.
“NVIDIA protects and enhances national security by creating U.S. jobs and infrastructure, promoting U.S. technology leadership, bringing billions of dollars of tax revenue to the U.S. treasury, and alleviating the massive U.S. trade deficit,” according to the statement.
One challenge for Nvidia is that the H20 was legal for export to China until last week, under previous Biden administration rules. But the House Select Committee said on Wednesday the sale of H20 chips for the past year was effectively a “loophole.”
“The technology industry supports America when it exports to well-known companies worldwide – if the government felt otherwise, it would instruct us,” Nvidia said in its statement.
The government is also investigating whether shipments of restricted chips to China went through Singapore, Nvidia’s second-largest market by billing address with just under $24 billion in sales in the company’s past fiscal year, according to filings.
Nvidia clarified on Wednesday that its Singapore revenue indicates sales with a billing address in the country, often for subsidiaries of U.S. customers.
“The associated products are shipped to other locations, including the United States and Taiwan, not to China,” Nvidia said.
In addition to Chinese export controls and the congressional investigation, Nvidia also faces additional restrictions on what it can export starting next month, under “AI diffusion rules” first proposed by the Biden administration.
Former Cybersecurity and Infrastructure Security Agency Director Chris Krebs testifies before a Senate Homeland Security and Governmental Affairs hearing to examine claims of voter irregularities in the 2020 election, in the Dirksen Senate Office Building, in Washington, U.S., December 16, 2020.

A week ago, President Donald Trump signed an executive order targeting former Cybersecurity and Infrastructure Security Agency Chief Chris Krebs, and calling on the government to suspend the security clearances of any entities with whom he’s associated. The order specifically named SentinelOne, Krebs’ employer.
On Wednesday, Krebs announced his resignation from SentinelOne, a cybersecurity company with a $5.6 billion market cap. While Krebs said the choice was his alone, his swift departure is the latest example of the effect Trump is having on the private sector when it comes to pressuring people and institutions that he personally dislikes.
Krebs had served as SentinelOne’s chief intelligence and public policy officer since late 2023, when the company acquired his consulting firm.
“For those who know me, you know I don’t shy away from tough fights,” Krebs wrote in an email to SentinelOne staffers that the company posted on its website. “But I also know this is one I need to take on fully — outside of SentinelOne. This will require my complete focus and energy. It’s a fight for democracy, for freedom of speech, and for the rule of law. I’m prepared to give it everything I’ve got.”
Krebs served as the first CISA director from 2018 until he was fired in November 2020 after declaring that the presidential election, which Democrat Joe Biden won, was “the most secure in American history.” CISA is part of the Department of Homeland Security.
In his executive order on April 9, which took the extraordinary approach of going after a specific individual, Trump called Krebs a “bad-faith actor who weaponized and abused his Government authority.”
“Krebs’ misconduct involved the censorship of disfavored speech implicating the 2020 election and COVID-19 pandemic,” the order said. “Krebs, through CISA, falsely and baselessly denied that the 2020 election was rigged and stolen, including by inappropriately and categorically dismissing widespread election malfeasance and serious vulnerabilities with voting machines.”
Trump directed the attorney general, director of national intelligence and “all other relevant agencies” to suspend “any active security clearances held by individuals at entities associated with Krebs, including SentinelOne, pending a review of whether such clearances are consistent with the national interest.”
The Wall Street Journal was first to report on Krebs’ departure from SentinelOne, publishing a story on Wednesday based on an interview with Krebs. He told the Journal that he was leaving to push back on Trump’s efforts “to go after corporate interests and corporate relationships.”
The demands on SentinelOne resemble campaigns that President Trump has waged against law firms and universities that he’s tried to strongarm into making significant changes in how they operate or else lose government contracts or funding.
SentinelOne, which uses artificial intelligence to detect threat and prevent cyberattacks, doesn’t disclose how much of its revenue comes from the government. But the company acknowledges in the risk factors section of its financial reports that it relies on government agencies for some of its business and can be hurt by changes in policy.
“Our future growth depends, in part, on increasing sales to government organizations,” the latest quarterly filing says. Specific to Trump, SentinelOne said that the establishment of the Department of Government Efficiency, which Elon Musk is running, could lead to budgetary changes that “adversely affect the funding for and purchases of our platform by government organizations.”
SentinelOne CEO Tomer Weingarten told employees in a memo, also posted to the company’s site on Wednesday, that Krebs “helped shape important conversations and strengthened public-private collaboration.” The company previously said, in a blog post after the executive order, that fewer than 10 employees had security clearances.
“Accordingly, we do not expect this to materially impact our business in any way,” the post said.
