OpenAI files EU complaint, alleges Google, Microsoft, Apple stifle AI competition
Challenging Google, Microsoft, and its own backer, OpenAI seeks EU action against AI market lock-in and data dominance.
October 10, 2025

In a significant move that underscores the escalating tensions within the artificial intelligence sector, OpenAI has formally voiced its concerns to European Union competition regulators regarding what it perceives as potentially harmful and anticompetitive behavior by technology giants Google, Microsoft, and Apple. This development signals a new phase in the complex relationships between established tech behemoths and the AI pioneers that are reshaping the digital landscape. The warnings from the influential AI firm highlight a growing apprehension that the immense market power of these established players could stifle innovation and unfairly disadvantage smaller competitors in the burgeoning field of artificial intelligence. At the heart of OpenAI's appeal to the EU is the contention that these tech giants are leveraging their entrenched positions to create barriers to entry and limit consumer choice.
A central pillar of OpenAI's argument revolves around the issue of "customer lock-in," a strategy where a company makes it difficult or costly for its customers to switch to a competitor's products or services.[1][2][3][4] In the context of AI, this could manifest in various ways, from the seamless integration of proprietary AI assistants into operating systems to the bundling of AI-powered features within existing software suites. OpenAI has suggested that such practices could prevent emerging AI companies from gaining a foothold in the market, as consumers may be less inclined to seek out third-party alternatives if a "good enough" option is already embedded in the platforms they use daily. The company has urged EU regulators to take proactive measures to prevent this lock-in and ensure a level playing field where the best products and services can succeed on their own merits.[1][2][3] This appeal aligns with the broader goals of the EU's Digital Markets Act (DMA), which seeks to rein in the power of so-called "gatekeeper" platforms and promote fairer competition.[5][6]
Another critical area of concern for OpenAI is the immense data advantage held by Google, Microsoft, and Apple. The development of sophisticated AI models is heavily reliant on vast datasets for training and refinement. OpenAI contends that these tech giants have unparalleled access to user data through their dominant search engines, operating systems, and cloud computing platforms, giving them a significant and potentially insurmountable edge over competitors.[4] This "data dominance" could create a vicious cycle where the companies with the most data can build the most powerful AI, which in turn attracts more users and generates even more data. OpenAI has stressed that access to key data is essential for fostering a competitive AI market.[4] This issue is particularly pertinent in the European Union, which has a strong focus on data protection and privacy. The DMA includes provisions that require gatekeepers to provide business users with access to the data they generate on the platform, a rule that could have significant implications for the AI sector.[5][6][7]
The complex and evolving relationship between OpenAI and its primary financial backer, Microsoft, adds another layer of intrigue to this regulatory appeal. While Microsoft has invested billions of dollars in OpenAI and integrated its technology into products like the Azure cloud platform, the two companies are also increasingly becoming direct competitors. Microsoft's own AI assistant, Copilot, directly rivals OpenAI's flagship product, ChatGPT. This dual role of partner and competitor creates a delicate and potentially fraught dynamic. OpenAI's decision to include Microsoft in its list of concerns for EU regulators suggests that the AI company is seeking to establish its independence and ensure that its growth is not constrained by its powerful benefactor. The European Commission has already been examining the nature of the partnership between Microsoft and OpenAI to determine if it falls under merger regulations, highlighting the intense scrutiny these collaborations are facing from antitrust authorities.
The implications of OpenAI's warning to EU regulators are far-reaching and could significantly shape the future of the artificial intelligence industry. If the European Commission decides to launch formal investigations into the practices of Google, Microsoft, and Apple, it could lead to new regulations or enforcement actions aimed at promoting a more open and competitive AI ecosystem. This could involve measures to improve data portability, prevent self-preferencing of their own AI services, and ensure fair access to app stores and other distribution channels. For consumers, a more competitive market could lead to a wider array of innovative AI products and services at more competitive prices. However, the tech giants are likely to argue that their integrated approach to AI development is beneficial for users, offering a more seamless and secure experience. As the European Union continues to position itself as a global leader in technology regulation, its response to OpenAI's concerns will be closely watched by policymakers and industry players around the world, setting a precedent for how to balance innovation and competition in the age of artificial intelligence.
