In a move that could shape how Europe regulates the rapidly evolving artificial intelligence (AI) sector, OpenAI has raised concerns with European Union regulators about growing anti-competitive behavior from dominant tech platforms. The company argues that the increasing concentration of power among a handful of tech giants threatens innovation and fair access to the future of AI.
According to documents reviewed by Reuters, OpenAI officials met with the European Commission’s antitrust unit on September 24, 2025, where they delivered a stark warning: unless regulators act, large technology platforms could use their existing dominance to lock users into their ecosystems and undermine competition in the emerging AI market (Reuters).
This meeting signals OpenAI’s effort to proactively shape the regulatory environment around AI, even as it continues to expand its own influence across the global tech landscape.
The September Meeting: OpenAI’s Key Arguments
In its private meeting with the Commission, OpenAI warned that major tech companies are leveraging their existing positions—especially in infrastructure, data access, and distribution channels—to gain an unfair advantage in AI services. The company emphasized that these strategies include vertical integration, restrictive intercompany agreements, and design choices that make it harder for users to switch to alternative platforms.
OpenAI expressed particular concern about a growing risk of “lock-in”—a scenario in which users become dependent on one provider’s services due to technical or contractual barriers that make switching difficult or costly (Reuters).
While OpenAI did not name specific companies during the meeting, outside sources suggested the concerns are especially relevant to Google, Apple, and Microsoft—all of which control critical platforms or resources essential for AI product distribution and development (Times of India).
Why This Matters Now
The timing of OpenAI’s intervention is significant. AI has become not only a transformative technology but also a geopolitical and economic force. OpenAI’s flagship product, ChatGPT, has surpassed 800 million weekly active users, and the company was recently valued at nearly $500 billion in a secondary share sale (Reuters).
This makes OpenAI both a disruptor and a market leader—putting it in a unique position to advocate for open competition while being scrutinized for its own growing power.
Moreover, the European Commission has already taken several steps toward regulating AI and Big Tech. In July 2025, EU regulators reviewed Microsoft’s multi-billion-dollar investment in OpenAI but concluded that the partnership did not constitute formal control under EU merger rules (AP News).
Still, the relationship remains under the microscope. EU competition officials said they would continue to examine whether the partnership restricts access for other market participants or gives Microsoft unfair advantages in integrating OpenAI models into its services like Azure and Bing.
Platform Power and AI Market Risks
OpenAI’s warnings point to a broader set of challenges facing the AI industry. In particular, access to massive datasets, computing infrastructure, and default integration into dominant consumer platforms (like mobile operating systems and browsers) is increasingly being concentrated in the hands of a few players.
This trend raises concerns about whether new entrants in AI will have a fair chance to compete. For example, companies like Google and Apple already control the primary interfaces through which hundreds of millions of people interact with digital services. They also have the advantage of closed ecosystems, where their own AI models can be pre-installed or preferentially promoted.
A recent report from Times of India highlighted that data dominance by tech giants such as Google, Apple, and Microsoft creates severe entry barriers for smaller players in the AI space. The report echoed OpenAI’s view that preferential access to infrastructure and user data could distort competition (Times of India).
The situation is particularly acute in cloud computing, where Amazon Web Services, Google Cloud, and Microsoft Azure dominate. These platforms are essential for training and running large-scale language models, and their owners have begun integrating proprietary AI tools into their own ecosystems—sometimes at the expense of third-party developers.
Microsoft–OpenAI Dynamics Under Scrutiny
While OpenAI raises valid concerns about Big Tech dominance, it is also deeply intertwined with one of the largest players—Microsoft.
The two companies maintain a close partnership. Microsoft has invested over $13 billion in OpenAI and uses its models in many of its core services. Though the EU found no formal control in its July 2025 review, Microsoft’s influence remains substantial (Financial Times).
To reduce regulatory heat, Microsoft gave up its observer seat on OpenAI’s board earlier in 2024. The move was viewed as an effort to signal independence and avoid accusations of shadow control (US News).
Nevertheless, the long-term implications of such tight collaborations remain under discussion among regulators, especially when partnerships involve access to exclusive data, infrastructure, or model outputs.
What the EU Might Do Next
OpenAI’s briefing to the European Commission may lead to a series of regulatory responses in the coming months.
One possible outcome is a formal competition inquiry into the AI practices of dominant platforms. The Commission could examine whether exclusive agreements, preferential access, or default integrations are impeding fair competition.
Another possibility is that the EU could impose new rules under the Digital Markets Act, such as requirements for data portability, interoperability, or restrictions on bundling proprietary AI tools into essential services like operating systems or browsers.
The EU might also push for industry-wide transparency and governance standards for AI, particularly around access to training data and model APIs, to ensure that new developers are not locked out of the market.
Lastly, OpenAI’s move could encourage other AI companies and developers to speak up about anti-competitive obstacles they face, potentially sparking a broader policy conversation across Europe and beyond.
Conclusion: A Strategic Warning or Self-Defense?
OpenAI’s decision to engage directly with European regulators could be interpreted in two ways: as a proactive call to preserve open competition in a rapidly consolidating industry, or as a strategic move to safeguard its own expansion from larger platform players.
Regardless of the motivation, the company’s message aligns with broader concerns about concentration in AI development and distribution. If left unchecked, dominant players could entrench themselves at every layer of the AI value chain—from infrastructure to interface.
As AI systems become central to everything from education to productivity to healthcare, ensuring a level playing field is not just a business issue—it’s a public interest concern.
What happens next will depend on whether EU regulators take the warning seriously and whether other companies and stakeholders rally around similar demands. The future of AI might not be decided solely by technological innovation, but by who controls access, distribution, and opportunity.
