Can antitrust enforcement deflate the AI bubble before the public pays

and accept "AI bubble" as the subject. But rule 1... I'll include entity. Final answer: "Can antitrust enforcement deflate the AI bubble before the public pays: the case of Microsoft and OpenAI cross-shareholding" Now summary_zh. Let me finalize: "The commentary argues that U.S. antitrust enforcement could deflate the AI bubble by dismantling cross-shareholdings among tech giants, avoiding cascading failures across interconnected networks when a single company fails. The article cites Microsoft's approximately 27% stake in OpenAI Group PBC, valued at $135 billion, as falling within Section 11 of the 2023 U.S. Merger Guidelines and interlocking directorate prohibitions. The AI bubble is driven by two financial loops: cloud-for-credit and mark-to-market. Amazon's stake in Anthropic contributed $16.8 billion in gains in Q1 2026."
