OpenAI warns EU regulators of Big Tech dominance in AI market

OpenAI has raised competition concerns with European Union regulators, warning that entrenched tech giants such as Google are using their market power to dominate the fast-growing artificial intelligence sector.

The company confirmed Thursday that its arguments to EU officials last month “mirrored its public positions” on the need to ensure fair competition in AI. During a September 24 meeting with EU antitrust chief Teresa Ribera, OpenAI said it faced major hurdles competing against vertically integrated platforms that control both infrastructure and distribution, according to meeting notes cited by Bloomberg News.

The firm urged regulators to prevent large companies from “locking in users” through their ecosystems — a reference to concerns that firms like Alphabet and Microsoft could tie AI products to existing search, cloud, and software services.

The European Commission has already been investigating how major technology platforms are extending dominance into AI through intercompany agreements and exclusive data access. Neither the Commission nor Google responded to requests for comment.

OpenAI’s outreach to EU authorities comes as it cements its own global influence. Following a secondary share sale last week, the ChatGPT-maker is now valued at $500 billion, making it the world’s most valuable startup with over 800 million weekly users.

Analysts say the move signals that OpenAI wants to shape the regulatory debate in Europe — not only to challenge rivals like Google and Anthropic, but also to secure its place in a market increasingly defined by antitrust scrutiny and AI sovereignty policies.

Google unveils Gemini Enterprise AI platform to expand corporate reach

Google, part of Alphabet, has launched Gemini Enterprise, a new AI platform for business clients designed to bring advanced artificial intelligence capabilities to the workplace. The move marks the company’s most significant push yet to compete with Microsoft, OpenAI, and Anthropic in the fast-growing enterprise AI sector.

Powered by Google’s most advanced Gemini AI models, the platform enables employees to converse directly with company data, documents, and applications, allowing faster decision-making and research. It offers both pre-built AI agents for common tasks — like data analysis and deep research — and tools for companies to build custom agents tailored to their operations.

Google said it has already signed major clients for Gemini Enterprise, including Gap, Figma, and Klarna, as the platform builds on the company’s existing Google Workspace suite, which integrates AI features across apps like Gmail, Docs, and Sheets.

The launch comes amid intensifying competition among tech giants seeking to monetize AI through enterprise subscriptions and workplace automation. Analysts view Gemini Enterprise as Google’s next step in turning its AI research into scalable business tools.

Harvard Medical School licenses health content to Microsoft for Copilot AI

Harvard Medical School has signed a licensing agreement with Microsoft, giving the tech giant access to its consumer health content on diseases and wellness topics, the university confirmed Wednesday. The deal, made through Harvard Health Publishing, aims to integrate verified medical information into Microsoft’s Copilot AI assistant.

A licensing fee will be paid to Harvard, though financial details were not disclosed. The content will enhance Copilot’s ability to provide accurate, evidence-based health insights, complementing its existing productivity tools like Word and Outlook.

The partnership is part of Microsoft’s broader push to reduce reliance on OpenAI’s models, which currently power much of its AI infrastructure. The Wall Street Journal reported that the new version of Copilot, expected to launch this month, will include Harvard’s content to deliver more reliable answers on medical and wellness topics.

Microsoft has also begun integrating Anthropic’s Claude and is developing its own AI models as part of a strategy to diversify its AI portfolio.

By combining Microsoft’s generative AI with Harvard’s trusted medical expertise, the partnership seeks to make health information more accessible and reliable for everyday users while maintaining accuracy and academic integrity.
