The European Commission has launched fresh antitrust investigations into Meta and Microsoft over their ties to artificial intelligence startups, signaling closer oversight of Big Tech’s growing influence in the fast-moving AI market.

According to Reuters, regulators are examining whether the companies’ partnerships could distort competition or give them unfair advantages as AI tools become more central to consumer and enterprise software. The probes come as European authorities step up efforts to prevent dominant platforms from locking up access to key technologies and talent.

Meta and Microsoft have both invested heavily in AI products and partnerships over the past two years, positioning themselves among the most powerful players in the sector. The new scrutiny reflects broader concern in Brussels that early deals in the AI industry could shape market access before rivals have a chance to compete on equal terms.

The investigations add to a growing list of regulatory challenges facing major technology firms in Europe, where lawmakers and competition officials have taken a tougher stance on mergers, data control, and platform power. The outcome could influence how large tech companies structure future AI investments across the region.
