OpenAI is planting a flag in Madrid, marking its latest move in an aggressive European expansion that now spans five cities across the continent. The office, set to open in the second half of 2026, will focus on building partnerships with Spanish companies, developers, research centers, and institutions.

What the Madrid office means for OpenAI’s European footprint

The Madrid location joins OpenAI’s existing European offices in London, Dublin, Paris, and Brussels.

Spain’s Digital Transformation Minister Óscar López publicly welcomed the announcement, framing it as validation of Spain’s approach to AI regulation. In his view, the country’s regulatory framework makes it more competitive in the global AI race rather than less so.

The office is designed to strengthen OpenAI’s ChatGPT offerings across the European market. That means deeper localization, more direct engagement with enterprise customers in the region, and a closer relationship with Spanish academic and research institutions that are increasingly working on AI applications.
