Newsletter Relevance
OpenAI’s scale and Microsoft relationship create a structural advantage that smaller AI companies (Anthropic, Mistral) are racing to overcome. The Microsoft deal is simultaneously the source of its enterprise dominance and a target of antitrust scrutiny. OpenAI is also the primary subject of EU AI Act high-impact model provisions — the first company to face systemic risk assessment requirements.
