An EU law that seeks to rein in large digital companies has officially kicked in, spelling big changes for primarily U.S. tech giants.
The European Union’s landmark Digital Markets Act officially became enforceable on Thursday. That means the European Commission, the EU executive arm, can start taking action against companies that breach the rules.
The Digital Markets Act aims to clamp down on anti-competitive practices from tech players, as well as force them to open out some of their services to other competitors. Smaller internet firms and other businesses have complained about being hurt by the practices of these companies.
Bill Echikson, a non-resident senior follow at the Center for European Policy Analysis (CEPA), said that the EU reforms mean that technology giants will graduate from “teenagers” to “grown-ups” now.
“There’s a lot of changes that could or could not happen. A lot of it is uncertain,” Echikson said. But, he added, the new law could inspire change in other countries, like the U.S. and the U.K. and ultimately force tech firms into global tweaks to their platforms.
CNBC runs through how the law impacts large U.S. tech companies — as well as consumers in the EU.
What does it mean for Big Tech?
The EU Digital Markets Act primarily impacts U.S. tech giants — the likes of Alphabet, Amazon, Apple, and Meta.
That’s because the rules impose strict curbs for so-called “gatekeepers” — firms with an entrenched position in their respective market, with a market capitalization of at least 75 billion euros ($81.7 billion) and with a platform with 45 million monthly active end users in the EU.
That makes U.S. tech giants a key target. So far, six firms have been designated gatekeepers: Alphabet, Amazon, Apple, Meta, Microsoft and China’s ByteDance — the sole non-U.S. firm on the list.
These companies are required to adjust their platforms to make competition healthier in the bloc.
For example, they must ensure they’re not giving their services preference over rivals on their own platforms. Google, for instance, can’t force users to select its own search engine on Android phones when they set up their devices and must show alternatives, like DuckDuckGo, or Ecosia.
Some messaging apps, like Facebook Messenger, must also make their services “interoperable” with third-party messaging services, so that users can message people using alternative products.
Companies with entrenched positions in app distribution must meanwhile also allow competing apps to appear on their platforms.
Apple has been ordered under the DMA to allow alternative app stores on iPhones for the first time.
The tech giant was this week slapped by the EU with a fine of more than 1.8 billion euro ($1.96 billion) for breaching competition rules, following an investigation into its App Store practices.
The EU thinks Apple broke the law by preventing app developers from informing iOS users about alternative and cheaper music subscription services available outside of the app. Spotify praised the Commission’s decision, while Apple denied its App Store violates the law.
The fine could be a sign of what’s to come, as DMA enforcement officially gets underway. Companies in persistent breach of the law can face fines as large as 10% of their global annual revenues.
How are EU citizens affected?
The rules have already sparked big changes for tech giants in how they serve customers in the EU.
It’s likely more adjustments will come, as competitors to Big Tech firms aren’t happy with the proposals put in place so far.
Apple recently announced it would open up its iPhone and iPad to alternative app stores. Developers have long complained about the 30% fee Apple charges on in-app purchases.
Still, app developers like Microsoft, Spotify and video game developer Epic Games remain unhappy, as Apple’s implementation adds hurdles beyond offering an installation file for download on their website.
Meta also says Facebook Messenger and WhatsApp can now work with third-party messaging services, so long as they follow the Signal end-to-end encryption protocol to ensure privacy.
For Google, meanwhile, there’s now a choice screen that lets users pick which search engine they want to set as their default on Android phones. This has already been in place, enabling the likes of Microsoft, Ecosia, and DuckDuckGo to get a place in a list of multiple search engine providers.
Google recently added even more choice screens. Rivals say this makes things unnecessarily complicated, as users have to click more than they’d like in order to set their main search provider.
“A lot of pop up screens are going to come because you’re going to get browser choices of other search engines in some ways,” CEPA’s Echikson said.
With Google, the actual search engine will change as well. The company removed flights from the search results for EU consumers, and search findings now also come up with a carousel of ads from price comparison sites when you look up a hotel.
Some experts worry this will actually lead to large online booking sites, like Booking.com, benefiting from the changes, rather small, local hotels.
“We’re going into new ground there’s a lot of uncertainties that could emerge,” Echikson said. “It might reinforce some of the gatekeepers as well as allow the small guys, the Davids, more room against the Goliaths.”

Tesla shares fell in premarket trade on Monday after CEO Elon Musk announced plans to form a new political party.
The stock was down 7.13% by 4:27 a.m. E.T.
Musk said over the weekend that the party would be called the “America Party” and could focus “on just 2 or 3 Senate seats and 8 to 10 House districts.” He suggested this would be “enough to serve as the deciding vote on contentious laws, ensuring that they serve the true will of the people.”
Now tech billionaire’s reinvolvement in the political arena is making investors nervous.
“Very simply Musk diving deeper into politics and now trying to take on the Beltway establishment is exactly the opposite direction that Tesla investors/shareholders want him to take during this crucial period for the Tesla story,” Dan Ives, global head of technology research at Wedbush Securities, said in a note on Sunday.
“While the core Musk supporters will back Musk at every turn no matter what, there is broader sense of exhaustion from many Tesla investors that Musk keeps heading down the political track.”
Musk’s previous political foray earned him Trump’s praise in the early days, but he has since drawn the ire of the U.S. president.
The two have clashed over various areas of policy, including Trump’s spending bill which Musk has said would increase America’s debt burden. Musk has taken issue to particular cuts to tax credits and support for solar and wind energy and electric vehicles.
Trump on Sunday called Musk’s move to form a political party “ridiculous,” adding that the Tesla boss had gone “completely off the rails.”
Musk is contending with more than just political turmoil. Tesla reported a 14% year-on-year decline in car deliveries in the second quarter, missing expectations. The company is facing rising competition, especially in its key market, China.

Artificial intelligence semiconductor startup Groq announced Monday it has established its first data center in Europe as it steps up its international expansion.
Groq, which is backed by investment arms of Samsung and Cisco, said the data center will be located in Helsinki, Finland and is in partnership with Equinix.
Groq is looking to take advantage of rising demand for AI services in Europe following other U.S. firms which have also ramped up investment in the region. The Nordics in particular is a popular location for the data facilities as the region has easy access to renewable energy and cooler climates. Last month, Nvidia CEO Jensen Huang was in Europe and signed several infrastructure deals, including data centers.
Groq, which is valued at $2.8 billion, designs a chip that the company calls a language processing unit (LPU). It is designed for inferencing rather training. Inferencing is when a pre-trained AI model interprets live data to come up with a result, much like the answers that are produced by popular chatbots.
While Nvidia has a stranglehold on the chips required for training huge AI models with its graphics processing units (GPUs), there is a swathe of startups hoping to take a slice of the pie when it comes to inferencing. SambaNova; Ampere, a company SoftBank is in the process of purchasing; Cerebras and Fractile, are all looking to join the AI inference race.
European politicians have been pushing the notion of sovereign AI — where data centers must be located in the region. Data centers that are located closer to users also help improve the speed of services.
Global data center builder Equinix connects different cloud providers together, such as Amazon Web Services and Google Cloud, making it easier for businesses to have multiple vendors. Groq’s LPUs will be installed inside the Equinix data center allowing businesses to access Groq’s inference capabilities via Equinix.
Groq currently has data centers in the U.S. and Canada and Saudi Arabia with its technology.

Hidden among the majestic canyons of the Utah desert, about 7 miles from the nearest town, is a small research facility meant to prepare humans for life on Mars.
The Mars Society, a nonprofit organization that runs the Mars Desert Research Station, or MDRS, invited CNBC to shadow one of its analog crews on a recent mission.
“MDRS is the best analog astronaut environment,” said Urban Koi, who served as health and safety officer for Crew 315. “The terrain is extremely similar to the Mars terrain and the protocols, research, science and engineering that occurs here is very similar to what we would do if we were to travel to Mars.”
SpaceX CEO and Mars advocate Elon Musk has said his company can get humans to Mars as early as 2029.
The 5-person Crew 315 spent two weeks living at the research station following the same procedures that they would on Mars.
David Laude, who served as the crew’s commander, described a typical day.
“So we all gather around by 7 a.m. around a common table in the upper deck and we have breakfast,” he said. “Around 8:00 we have our first meeting of the day where we plan out the day. And then in the morning, we usually have an EVA of two or three people and usually another one in the afternoon.”
An EVA refers to extravehicular activity. In NASA speak, EVAs refer to spacewalks, when astronauts leave the pressurized space station and must wear spacesuits to survive in space.
“I think the most challenging thing about these analog missions is just getting into a rhythm. … Although here the risk is lower, on Mars performing those daily tasks are what keeps us alive,” said Michael Andrews, the engineer for Crew 315.
