European Union regulators on Thursday opened an antitrust investigation into Microsoft’s bundling of its video and chat app Teams with other Office products.
The European Commission, the EU’s executive arm, said that these practices may constitute anti-competitive behavior.

It is the first antitrust investigation by the EU into Microsoft in over a decade.
“The Commission is concerned that Microsoft may grant Teams a distribution advantage by not giving customers the choice on whether or not to include access to that product when they subscribe to their productivity suites and may have limited the interoperability between its productivity suites and competing offerings,” the EU regulators said on Thursday in a press release.
In other words, the EU is concerned Microsoft is not giving customers the choice to not buy Teams when they subscribe to the company’s Office 365 product. In doing so, Microsoft might be stopping other companies from competing in the workplace messaging and video app space.
“These practices may constitute anti-competitive tying or bundling and prevent suppliers of other communication and collaboration tools from competing,” the Commission added.
Microsoft 365, previously known as Office 365, is Microsoft’s set of software which includes workplace-geared apps like Word and Excel.
Antitrust investigations do not have a self-imposed completion deadline. If Microsoft is found to be in breach of EU competition rules, the U.S. tech giant could face a fine of up to 10% of its total global annual turnover.
Slack raises concerns
Concerns over Microsoft on competitiveness grounds were first raised in 2020, when Teams rival Slack submitted a complaint to the EU, in which it alleged the Redmond tech giant illegally tied Teams to its dominant productivity packages, such as Microsoft 365. Slack, which is owned by Salesforce, has said the move meant millions of users were forced to install Teams without the ability to remove it.
A Microsoft spokesperson said, “We respect the European Commission’s work on this case and take our own responsibilities very seriously. We will continue to cooperate with the Commission and remain committed to finding solutions that will address its concerns.”
Microsoft was last subjected to an EU antitrust probe in 2009, in a similar case over its former web browser Internet Explorer. The EU raised concerns that competition was distorted by Microsoft tying Internet Explorer to its Windows operating system. Microsoft offered remedies to the EU, committing to allow Windows users a choice of rival web browsers.
More recently, Microsoft’s proposed $69 billion acquisition of Activision Blizzard came under EU scrutiny, on grounds that the deal may distort competition in the console and cloud gaming market. Microsoft offered remedies to the EU in this case, leading to regulators approving the deal in May.

It’s been a brutal year for Tesla shareholders so far, and a hugely profitable one for short sellers, who bet on a decline in the company’s stock price.
Tesla shorts have generated $11.5 billion in mark-to-market profits in 2025, according to data from S3 Partners. The data reflected Monday’s closing price of $227.50, at which point Tesla shares were down 44% for the year.
The stock rallied about 4% on Tuesday, along with gains in the broader market, heading into Tesla’s first-quarter earnings report after the close of trading. Tesla didn’t immediately respond to a request for comment.
The electric vehicle maker is expected to report a slight decline in year-over-year revenue weeks after announcing a 13% drop in vehicle deliveries for the quarter. With CEO Elon Musk playing a central role in President Donald Trump’s administration, responsible for dramatically cutting the size and capacity of the federal government, Tesla has faced widespread protests in the U.S. and Europe, where Musk has actively supported Germany’s far-right AfD party.
Tesla shares plummeted 36% in the first quarter, their worst performance for any period since 2022, and have continued to drop in April, largely on concerns that President Trump’s sweeping tariffs on top trade partners will increase the cost of parts and materials crucial for EV production, including manufacturing equipment,automotive glass, printed circuit boards and battery cells.
The company is also struggling to keep pace with lower-cost competitors in China, and is a laggard in the robotaxi market, which is currently dominated in the U.S. by Alphabet’s Waymo. Tesla has promised to launch its first driverless ride-hailing offering in Austin, Texas, in June.
Tesla has been the biggest stock decliner among tech megacaps this year, followed by Nvidia, which was down about 28% as of Monday’s close. The chipmaker has been the second-best profit generator for short sellers, generating returns of $9.4 billion, according to S3.
Nvidia is currently the most-shorted stock in terms of value, with $24.6 billion worth sold short, S3 said. Apple is second at $22.2 billion, and Tesla is third at $17.6 billion.
Musk has a long and antagonistic history with short sellers, who have made plenty of money at times during Tesla’s 15 years on the stock market, but have also been burned badly for extended stretches.
In 2020, Tesla publicly mocked short sellers, promoting red satin shorts for sale.
“Limited edition shorts now available at Tesla.com/shortshorts” Musk wrote in a social media post in July of that year, as the stock was in the midst of a steep rally.
Two years earlier, hedge fund manager David Einhorn of Greenlight Capital posted a tweet that he received the pairs of short shorts that Musk had promised him.
“I want to thank @elonmusk for the shorts. He is a man of his word!” Einhorn wrote. Einhorn had previously disclosed that his firm’s bet against Tesla “was our second biggest loser” in the most recent quarter.
In February 2022, after reports surfaced that the Department of Justice was investigating two investors who had shorted Tesla’s stock, Musk told CNBC that he was “greatly encouraged” by the action and said “hedge funds have used short selling and complex derivatives to take advantage of small investors.”
PlainSite founder Aaron Greenspan, a former Tesla short seller and outspoken critic of Musk, sued the Tesla CEO alleging he engaged in stock price manipulation for years through a variety of schemes.
The case was removed to federal court last year. In 2023, Musk’s social network X banned Greenspan and PlainSite, which publishes legal and other public and company records, from the platform.
Instagram on Tuesday launched its standalone Edits video creation app that offers features similar to those already available from TikTok parent Bytedance.
The new app allows creators to organize project ideas, shoot and edit video, and access insights about content. Edits includes background replacement, automatic captioning and artificial intelligence tools that can turn images into video.
“There’s a lot going on in the world right now and no matter what happens, we think it’s our job to create the most compelling creative tools for those of you who make videos for not just Instagram but for platforms out there,” said Adam Mosseri, the head of Instagram, in a Reel posted in January announcing the app.
Edits appears to be Meta‘s answer to CapCut, TikTok’s sister app that is also owned by China-based parent company ByteDance, which allows users to create and edit video on their phone or computer.

With TikTok’s future uncertain, Instagram’s move to launch Edits could be seen as a step to gain ground in the next era of short video creation in the creator economy.
Earlier this month, President Donald Trump for a second time extended the deadline for ByteDance to divest TikTok’s U.S. operations or face an effective ban. The deadline is now mid-June.

Tesla is set to report first-quarter earnings on Tuesday after market close.
Here’s what Wall Street is expecting, based on a survey of analysts by LSEG:
Earnings per share: 39 cents
Revenue: $21.11 billion
Tesla is expected to report a slight revenue decline from $21.3 billion in the same quarter a year earlier. However, investors are going to be more focused on what the future holds after concerns about tariffs and CEO Elon Musk’s close ties to the White House pushed the stock price down 44% so far this year as of Monday’s close.
Earlier this month, Tesla reported a 13% decline in deliveries to 336,681. Tesla blamed the lower deliveries, in part, on the need to suspend production temporarily at its factories while it upgraded lines to start manufacturing a refreshed version of its popular Model Y electric SUVs.
Deliveries are the closest approximation of vehicle sales reported by Tesla but are not precisely defined in the company’s shareholder communications.
At an all-hands meeting with employees last month, Musk tried to reassure staffers that they were still in good hands, and to “hang onto your stock.” He pointed to the popularity of the Model Y, and Tesla’s potential in robotics, artificial intelligence and autonomous vehicle technology.
At the meeting, Musk also made light of the backlash against Tesla elicited by his work for President Donald Trump to reduce the size of the federal government, and his endorsements of Germany’s anti-immigrant AfD party, along with other political rhetoric and antics.
“If you read the news it feels like, you know, Armageddon,” Musk said on a livestream of the employees meeting. “It’s like, I can’t walk past the TV without seeing a Tesla on fire.” He followed up saying, “This is psycho, stop being psycho!”
That was before Trump’s announcement earlier this month of widespread tariffs, the one area where Musk has publicly broken with the Trump administration. On X, he called Peter Navarro, Trump’s top trade advisor and tariff proponent, a “moron” and “dumber than a sack of bricks.”
Tesla stands to take a significant hit from the president’s proposed tariffs, assuming they don’t get rolled back. Tesla manufactures cars in the U.S. for domestic sales so it’s not subject to the 25% tariff on imported autos, but the hefty levies on other components and materials could be severe.
Tesla relies on suppliers in Mexico and China for items like automotive glass, printed circuit boards and battery cells, among other parts essential for the production of its cars. The company has sought an exemption from the U.S. trade representative for equipment imported from China that it uses in its factories.
