Alphabet shares slid 6% Thursday, following news that the Department of Justice is calling for Google to divest its Chrome browser to put an end to its search monopoly.

The proposed break-up would, according to the DOJ in its Wednesday filing, “permanently stop Google’s control of this critical search access point and allow rival search engines the ability to access the browser that for many users is a gateway to the internet.”

This development is the latest in a years-long, bipartisan antitrust case that found in an August ruling that the search giant held an illegal monopoly in both search and text advertising, violating Section 2 of the Sherman Act.

The potential break-up would include preventing Google from entering into exclusionary agreements with competitors like Apple and Samsung, part of a set of remedies that would last 10 years.

Nvidia shares dropped in U.S. premarket trading Thursday after the tech giant’s third-quarter earnings failed to impress investors.

Shares of the chipmaker slumped 3.21% at around 5:03 a.m. ET, following the Wednesday release of Nvidia’s quarterly results, which beat on both the top and bottom lines.

Revenue came in at $35.08 billion, up 94% year-on-year and exceeding the $33.16 billion forecast by LSEG analysts. Earnings per share was 81 cents adjusted, also above analyst expectations.

Other chipmakers fell on the back of the market reaction to Nvidia’s third-quarter results. Shares of Intel, Qualcomm and Micron Technology all lost 1% or more in value, while AMD declined 0.6%.

The slump in Nvidia also had a knock-on effect on European semiconductor firms. ASML, a key chip equipment supplier, dropped 0.9%, while compatriot Dutch chip firm ASMI fell 0.5%. Chipmakers BE Semiconductor, STMicroelectronics and Infineon slipped 0.8%, 0.7 and 0.6%, respectively.  

Several notable chip names were also in negative territory in Asia. TSMC, which makes Nvidia’s high-performance graphics processing units, eased as much as 1.5%. Contract electronics manufacturer Foxconn dropped 1.9%.

Analysts are looking ahead to the much-anticipated launch of Nvidia’s next-generation chip called Blackwell. On the firm’s earnings call, CEO Jensen Huang said that demand for the chip is exceeding supply.

LONDON — Britain’s competition regulator is preparing remedies aimed at solving competition issues in the multibillion-pound cloud computing industry.

The Competition and Markets Authority is set to unveil its provisional decision detailing “behavioral” remedies addressing anti-competitive practices in the sector following a months-long investigation into the market, two sources familiar with the matter told CNBC.

The sources, who preferred to remain anonymous given the investigation’s sensitive nature, said that the cloud market remedies could be announced within the next two weeks. The regulator previously set itself a deadline of November to December 2024 to publish its provisional decision.

A CMA spokesperson declined to comment on the timing of its provisional decision when asked by CNBC.

Cloud infrastructure services is a market that’s dominated by U.S. technology giants Amazon and Microsoft. Amazon is the largest player in the market, offering cloud services via its Amazon Web Services (AWS) arm. Microsoft is the second-largest provider, selling cloud products under its Microsoft Azure unit.

The CMA probe traces its history back to 2022, when U.K. telecoms regulator Ofcom kicked off a market study examining the dominance of cloud giants Amazon, Microsoft and Google. Ofcom subsequently referred its cloud review to the CMA to address competition issues in the market.

The watchdog said in a working paper in June that it was “at an early stage” of considering potential remedies.

Solutions floated at the time included imposing price controls restricting the level of egress fees, lowering technical barriers to switching cloud providers, and banning agreements encouraging firms to commit more spend in return for discounts.

One contentious measure the regulator said it was considering was requiring Microsoft to apply the same pricing for its productivity software products regardless of which cloud they’re hosted on — a move that would have a significant impact on Microsoft’s pricing structures.

CMA Chief Executive Sarah Cardell is set to hold a speech on Thursday at Chatham House, a U.K. policy institute. In an interview with the Financial Times, she defended the regulator’s track record on competition enforcement amid criticisms from Prime Minister Keir Starmer that the agency was holding back growth.

She is expected to outline plans for a review in 2025 into whether the CMA should more frequently use behavioral remedies when approving deals, the FT reported.
