Eight U.S. newspaper publishers filed suit against Microsoft and OpenAI in a New York federal court on Tuesday, claiming the technology companies reuse their articles without permission in generative artificial intelligence products and incorrectly attribute inaccurate information to them.
The group of eight newspaper publishers takes issue with ChatGPT and Microsoft’s Copilot assistant — available in the Windows operating system, the Bing search engine, and other products the software maker produces. ChatGPT and Copilot have been “purloining millions of the publishers’ copyrighted articles without permission and without payment,” according to the complaint, which had been filed in the U.S. District Court for the Southern District of New York.
The newspaper publishers in the lawsuit operate the New York Daily News, the Chicago Tribune, the Orlando Sentinel, the Sun Sentinel in Florida, The Mercury News in California, The Denver Post, The Orange County Register in California and the Pioneer Press of Minnesota.
The newspaper publishers said in the lawsuit that OpenAI has drawn on data sets containing text from their newspapers to train its GPT-2 and GPT-3 large language models, which can spit out text in response to a few words of human input.
“The current GPT-4 LLM will output near-verbatim copies of significant portions of the publishers’ works when prompted to do so,” the complaint said, showing several examples of ChatGPT and the Copilot allegedly doing so.
The publishers said Microsoft copies information from their newspapers for the Bing search index, which helps inform answers in the Copilot. But such output doesn’t always provide links to newspaper websites, where they can view ads alongside articles or pay for subscriptions.
Microsoft and OpenAI representatives did not immediately respond to requests for comment from CNBC.
The legal challenge comes four months after The New York Times sued OpenAI over copyright infringement in the ChatGPT chatbot that the startup released in late 2022. OpenAI said in a January blog post that the case is without merit, adding it wants to support “a healthy news ecosystem.” That same month, Sam Altman, OpenAI’s CEO, said the startup wanted to pay The New York Times and was surprised to learn about the lawsuit.
In recent months, OpenAI has signed deals with a handful of media companies, including Axel Springer and the Financial Times, enabling the Microsoft-backed startup to draw on the publishers’ content to improve AI models.
Google, which has its own general-purpose chatbot for responding to user queries, said in February that it had reached an agreement with Reddit that includes the right to train AI models on the platform’s content.
The New York Times case also touched on the matter of OpenAI models regurgitating information from its articles. In its blog post, OpenAI characterized such behavior as “a rare failure of the learning process that we are continually making progress on.”

Navan, the business travel, payments, and expense management startup, filed on Friday afternoon to go public.
Its S-1 filing with the Securities and Exchange Commission indicates that the company plans to list on the Nasdaq Global Select Market under the symbol “NAVN.”
Navan reported trailing 12-month revenue of $613 million (up 32%) across over 10,000 customers, and gross bookings of $7.6 billion (up 34%), according to the S-1 filing.
Goldman Sachs and Citigroup will act as lead book-running managers for the proposed offering.
Navan ranked No. 39 on this year’s CNBC Disruptor 50 list, and also made the 2024 list.
The IPO market has bounced back this year, with deal activity up 56% across 156 deals (roughly 200 IPO filings in all) and $30 billion in proceeds, up over 23% year over year, according to IPO tracker Renaissance Capital. It has been the best year for IPOs since 2021, though still far below the Covid offering boom years, when over $142 billion (2021) and $78 billion (2020) was raised by IPOs.
This year’s deal flow has been highlighted by hot AI names like Coreweave, as well as some of the startup world’s most highly valued firms from the past decade, such as fintech Klarna and design firm Figma, crypto companies Circle, Bullish and Gemini, and some long-awaited IPO candidates finally hitting the market, such as Stubhub this week, though its shares have slumped since the first day of trading. Top Amazon reseller Pattern went public on Friday.
Launched by CEO Ariel Cohen and co-founder Ilan Twig in 2015, Navan set out to disrupt a business travel sector where incumbents relied on clunky legacy tools and fragmented workflows.
The Palo Alto-based company, formerly called TripActions, refers to itself as an “all-in-one super app” for corporate travel and expenses.
Customers include Unilever, Adobe, Christie’s, Blue Origin and Geico.
It has also been pushing further into AI, with a virtual assistant named Ava handling approximately 50% of user interactions during the six months ended July 31, according to the filing, and a proprietary AI framework called Navan Cognition supporting its platform, as well as proprietary cloud infrastructure.
“We built Navan for the road warriors, for CEOs and CFOs who understand travel’s critical importance to their strategy, the finance teams who demand precision and control, the executive assistants juggling itineraries, and the program admins ensuring seamless events,” the co-founders wrote in an IPO filing letter.
“We saw firsthand the frustration of clunky, outdated systems. Travelers were forced to cobble together solutions, wait for hours on hold to book or change travel, and negotiate with travel agents. They struggled to adhere to company policies, with little visibility into those policies, and after all that, they spent even more time on tedious expense reports after a trip. We felt the pain of finance teams struggling to gain visibility into fragmented travel spending and to enforce policies, and the frustration of suppliers unable to connect directly with the high-value business travelers they sought to serve,” they wrote in the filing.
Revenue grew 33% year-over-year from $402 million in fiscal 2024 to $537 million in fiscal 2025, according to the S-1 filing. The company reported a net loss that decreased 45% year-over-year from $332 million in fiscal 2024 to $181 million in fiscal 2025. Gross margin improved from 60% in fiscal 2024 to 68% in fiscal 2025.
The business travel and expense space is crowded, with fellow Disruptors Ramp and Brex, and TravelPerk, as well as incumbents like SAP Concur and American Express Global Business Travel.

Microsoft said on Friday that it will increase the recommended retail price of several Xbox consoles in the U.S. starting in October because of “changes in the macroeconomic environment.”
The company said it would not increase prices for accessories such as controllers and headsets, and that prices in other countries would stay the same.
While Microsoft didn’t explicitly attribute the increase to the Trump administration’s tariffs, many consumer companies have been warning for months that higher prices are on the way. President Donald Trump has issued tariffs this year on multiple countries with a stated goal to bring more manufacturing to the U.S.
“We understand that these changes are challenging, and they were made with careful consideration,” Microsoft said on its website.
It’s the second time Microsoft has raised prices on its consoles in the U.S. this year. Rivals Sony and Nintendo have also raisedconsole prices in the U.S. as Trump’s tariffs went into effect.

After a long wait to get public, StubHub has had a rough start to life on the New York Stock Exchange.
Shares of the online ticket vendor dropped 10% on Friday, falling for a third straight day since debuting on Wednesday. At $18.46, the stock is now down 21% from its IPO price of $23.50.
StubHub, trading under ticker symbol “STUB,” has lagged behind fellow market newcomers like online lender Klarna, design software company Figma and stablecoin issuer Circle, which delivered early returns for investors following their recent IPOs. Shares of cybersecurity firm Netskope also rose 10% on Friday in their second trading day, after an initial pop on Thursday.
StubHub had been trying to go public for the past several years, but delayed its debut twice. The most recent stall came in April after President Donald Trump’s announcement of sweeping tariffs roiled markets. The company filed an updated prospectus in August, effectively restarting the process to go public, and has since seen its market cap slip to about $6.8 billion from $8.6 billion at its IPO.
Founded in 2000, StubHub primarily generates revenue from connecting buyers with ticket resellers. In the first quarter, revenue rose 10% from a year earlier to $397.6 million. The company’s net loss widened to $35.9 million from $29.7 million a year ago.
StubHub CEO Eric Baker told CNBC on Wednesday that the company expects recently introduced federal regulations around transparent ticket pricing to cause a “one-time” hit to its financial results.
Regulators are zeroing in on online ticket sellers over their pricing mechanisms and whether the companies are doing enough to keep automated purchasing bots in check. The Federal Trade Commission on Thursday sued StubHub rival Live Nation Entertainment, the parent company of Ticketmaster, accusing it of illegal resale tactics.
While StubHub has failed to excite Wall Street, its struggles haven’t seeped into other deals as the tech IPO market continues to show signs of a resurgence after an extended dry spell. Amazon reseller Pattern Group saw its stock rise 12% on Friday, though shares initially slipped 6%.
