Google’s antitrust woes are continuing to mount, just as the company tries to brace for a future dominated by artificial intelligence.
On Thursday, a federal judge ruled that Google held illegal monopolies in online advertising markets due to its position between ad buyers and sellers.
The ruling, which followed a September trial in Alexandria, Virginia, represents a second major antitrust blow for Google in under a year. In August, a judge determined the company has held a monopoly in its core market of internet search, the most-significant antitrust ruling in the tech industry since the case against Microsoftmore than 20 years ago.
Google is in a particularly precarious spot as it tries to simultaneously defend its primary business in court while fending off an onslaught of new competition due to the emergence of generative AI, most notably OpenAI’s ChatGPT, which offers users alternative ways to search for information. Revenue growth has cooled in recent years, and Google also now faces the added potential of a slowdown in ad spending due to economic concerns from President Donald Trump’s sweeping new tariffs.
Parent company Alphabet reports first-quarter results next week. Alphabet’s stock price dipped more than 1% on Thursday and is now down 20% this year.
In Thursday’s ruling, U.S. District Judge Leonie Brinkema said Google’s anticompetitive practices “substantially harmed” publishers and users on the web. The trial featured 39 live witnesses, depositions from an additional 20 witnesses and hundreds of exhibits.
Judge Brinkema ruled that Google unlawfully controls two of the three parts of the advertising technology market: the publisher ad server market and ad exchange market. Brinkema dismissed the third part of the case, determining that tools used for general display advertising can’t clearly be defined as Google’s own market. In particular, the judge cited the purchases of DoubleClick and Admeld and said the government failed to show those “acquisitions were anticompetitive.”
“We won half of this case and we will appeal the other half,” Lee-Anne Mulholland, Google’s vice president or regulatory affairs, said in an emailed statement. “We disagree with the Court’s decision regarding our publisher tools. Publishers have many options and they choose Google because our ad tech tools are simple, affordable and effective.”
Attorney General Pam Bondi said in a press release from the DOJ that the ruling represents a “landmark victory in the ongoing fight to stop Google from monopolizing the digital public square.”
Potential ad disruption
If regulators force the company to divest parts of the ad-tech business, as the Justice Department has requested, it could open up opportunities for smaller players and other competitors to fill the void and snap up valuable market share. Amazon has been growing its ad business in recent years.
Meanwhile, Google is still defending itself against claims that its search has acted as a monopoly by creating strong barriers to entry and a feedback loop that sustained its dominance. Google said in August, immediately after the search case ruling, that it would appeal, meaning the matter can play out in court for years even after the remedies are determined.
The remedies trial, which will lay out the consequences, begins next week. The Justice Department is aiming for a break up of Google’s Chrome browser and eliminating exclusive agreements, like its deal with Apple for search on iPhones. The judge is expected to make the ruling by August.

After the ad market ruling on Thursday, Gartner’s Andrew Frank said Google’s “conflicts of interest” are apparent by how the market runs.
“The structure has been decades in the making,” Frank said, adding that “untangling that would be a significant challenge, particularly since lawyers don’t tend to be system architects.”
However, the uncertainty that comes with a potentially years-long appeals process means many publishers and advertisers will be waiting to see how things shake out before making any big decisions given how much they rely on Google’s technology.
“Google will have incentives to encourage more competition possibly by loosening certain restrictions on certain media it controls, YouTube being one of them,” Frank said. “Those kind of incentives may create opportunities for other publishers or ad tech players.”
A date for the remedies trial hasn’t been set.
Damian Rollison, senior director of market insights for marketing platform Soci, said the revenue hit from the ad market case could be more dramatic than the impact from the search case.
“The company stands to lose a lot more in material terms if its ad business, long its main source of revenue, is broken up,” Rollison said in an email. “Whereas divisions like Chrome are more strategically important.”
Elon Musk on Monday threatened Apple with legal action over alleged antitrust violations related to rankings of the Grok AI chatbot app, which is owned by his artificial intelligence startup xAI.
“Apple is behaving in a manner that makes it impossible for any AI company besides OpenAI to reach #1 in the App Store, which is an unequivocal antitrust violation. xAI will take immediate legal action,” Musk wrote in a post on social media platform X.
Apple did not immediately respond to CNBC’s request for comment.
“Why do you refuse to put either X or Grok in your “Must Have” section when X is the #1 news app in the world and Grok is #5 among all apps? Are you playing politics?” Musk said in another post.
Apple last year tied up with OpenAI to integrate ChatGPT into its iPhone, iPad, Mac laptop and desktop products. Musk at that time had said that “If Apple integrates OpenAI at the OS level, then Apple devices will be banned at my companies. That is an unacceptable security violation.”
CNBC confirmed that ChatGPT was ranked No. 1 in the top free apps section of the American iOS store, and was the only AI chatbot in Apple’s “Must-Have Apps” section.
Prior to his legal threats against Apple, Musk had celebrated Grok surpassing Google as the fifth top free app on the App Store.
OpenAI on Thursday announced GPT-5, its latest and most advanced large-scale AI model, following xAI Grok 4 chatbot released last month.
This is not the first time Apple has been challenged on antitrust grounds. The Department of Justice last year sued Apple over iPhone ecosystem monopoly.
In June, a panel of judges denied Apple’s emergency application to halt the changes to its App Store. The iPhone maker had requested the appeals court to pause an order that said the company could no longer charge a commission on payment links inside its apps nor tell developers how the links should look.

President Donald Trump said Monday that he and members of his cabinet met with Intel CEO Lip-Bu Tan, days after he called on the head of the chipmaker to resign. Intel shares rose 2% in extended trading.
“I met with Mr. Lip-Bu Tan, of Intel, along with Secretary of Commerce, Howard Lutnick, and Secretary of the Treasury, Scott Bessent,” Trump wrote in a post on Truth Social. “The meeting was a very interesting one. His success and rise is an amazing story. Mr. Tan and my Cabinet members are going to spend time together, and bring suggestions to me during the next week. Thank you for your attention to this matter!”
An Intel spokesperson confirmed the meeting.
“Earlier today, Mr. Tan had the honor of meeting with President Trump for a candid and constructive discussion on Intel’s commitment to strengthening U.S. technology and manufacturing leadership,” the spokesperson wrote in an email.
Tan has been an Intel director since 2022, and in March he replaced Pat Gelsinger as CEO. Last week Sen. Tom Cotton, R-Ark., questioned Tan’s ties to China. Cotton brought up a past criminal case involving Cadence Design, where Tan had been CEO, and asked whether Intel required Tan to divest from positions in chipmakers linked to the Chinese Communist Party, the People’s Liberation Army and any other concerning entities in China.
Trump’s latest message marks a stark change in tone from last week. In a Truth Social post on Thursday, the president wrote that Tan “is highly CONFLICTED and must resign, immediately. There is no other solution to this problem.”
Intel said in a comment later that day that the company, directors and Tan are “deeply committed to advancing U.S. national and economic security interests.”
The Trump administration has taken a heavy hand in the business world, particularly in the semiconductor market, as the U.S. battles with China for supremacy in artificial intelligence. Over the weekend, Nvidia agreed to pay the federal government a 15% cut in return for receiving export control licenses that will allow it to once again sell its H20 chip to China and Chinese companies. Nvidia CEO Jensen Huang visited Trump in the White House on Friday.
President Trump on Monday said that he initially asked Nvidia for a 20% cut of the chipmaker’s sales to China, but the number came down to 15% after Huang negotiated with him.
“I said, ‘listen, I want 20% if I’m going to approve this for you, for the country,'” Trump said at a news conference in Washington, D.C.
Tan, 65, took over Intel after the struggling chipmaker had failed to gain significant traction in the AI market, which Nvidia dominates, while it was burning cash to build its foundry business for chip manufacturing.
Tan was born in Malaysia and raised in Singapore before moving to the U.S. and receiving a master’s degree from the Massachusetts Institute of Technology. He said in late July that his first few months as Intel’s CEO had not been easy, with layoffs and cuts to the foundry division.
Intel canceled plans for manufacturing sites in Germany and Poland and would slow down development in Ohio, he told employees.
“Turning the company around will take time and require patience,” Tan said on a conference call with analysts in July. “We have a lot to fix in order to move the company forward.”
Intel shares are up 3% this year as of Monday’s close. The S&P 500 is up 8.4%.
StubHub, the ticketing marketplace that spun out of eBay in 2020, has resumed its plans to go public and is now aiming to hold its IPO next month, CNBC has learned.
The company originally paused its IPO plans in April as the stock market was reeling from President Donald Trump’s “liberation day” tariffs. The decision came after StubHub submitted its prospectus in March indicating it would list on the New York Stock Exchange under the ticker “STUB.”
StubHub now expects to kick off its IPO roadshow after Labor Day, Sept. 1, and make its debut later in the month, according to a source familiar with the matter who asked not to be named because the discussions are confidential.
The company didn’t immediately respond to a request for comment.
StubHub also filed an updated IPO prospectus on Monday. It reported revenue growth in the first quarter of 10% from a year earlier to $397.6 million. Operating income came in at $26.8 million for the period, after the company lost $883,000 in the year-ago period, but its net loss widened to $35.9 million from $29.7 million a year ago.
The IPO market has come to life in recent months after an extended dry spell due to high inflation and rising interest rates. A flurry of startups have made their public debuts, including rocket maker Firefly Aerospace, design software company Figma, crypto firm Circle and AI infrastructure provider CoreWeave. Bullish, the cryptocurrency exchange that counts Peter Thiel as an investor, also filed its IPO prospectus last month.
StubHub has been a longtime player in the ticketing industry since its launch in 2000. It was purchased by eBay for $310 million in 2007, but was reacquired by its co-founder Eric Baker in 2020 for $4 billion through his new company Viagogo.
The company had sought a $16.5 billion valuation before it began the IPO process, CNBC previously reported. StubHub didn’t provide an expected pricing range for its shares in the filing.
As it prepares to go public, StubHub is contending with hefty competition in the online ticketing market. In addition to Ticketmaster, which is owned by Live Nation, StubHub is up against secondary market companies, including Vivid Seats, SeatGeek and TicketNetwork
For the first quarter, StubHub reported gross merchandise sales of $2.08 billion, up 15% from a year prior. That was a slowdown from 47% expansion the previous quarter. StubHub said GMS, or the total value paid by buyers for tickets and fulfillment, builds in each quarter and that initial sales for major concert tours typically occur near the end of the year.
