Inside Microsoft’s complicated relationship with OpenAI

Tensions are reportedly rising between Microsoft and OpenAI, fueled by OpenAI's desire for more compute power and less reliance on Microsoft, particularly regarding the AI coding tool Windsurf; OpenAI is considering accusing Microsoft of anticompetitive behavior, potentially triggering regulatory scrutiny of their $13 billion partnership. Microsoft has been hedging its bets by developing alternative AI models and platforms, indicating a potential shift towards direct competition despite the complex revenue-sharing agreements currently in place.

Analysis

The strategic partnership between Microsoft and OpenAI, underpinned by a $13 billion investment, is reportedly under significant strain, primarily driven by OpenAI's pursuit of increased compute power, reduced dependency on Microsoft, and ambitions to convert part of its business to a for-profit entity. Tensions have escalated to the point where OpenAI executives are reportedly considering accusing Microsoft of anticompetitive behavior, a move that could intensify regulatory scrutiny from bodies like the FTC, which already has an open investigation into Microsoft's AI dealings. This evolving dynamic is complicated by intricate revenue-sharing agreements: Microsoft receives 20% of OpenAI's ChatGPT and API revenue, while also invoicing OpenAI for inferencing services; conversely, Microsoft pays OpenAI 20% of its Azure OpenAI service revenue and potentially up to 20% of incremental Bing/Edge advertising revenue. Microsoft is also entitled to up to 49% of OpenAI's for-profit arm's profits, though OpenAI is reportedly seeking to renegotiate this for a ~33% equity stake. The November 2023 ousting and reinstatement of Sam Altman reportedly eroded Microsoft's confidence, prompting proactive hedging strategies. These include accelerating the development and hosting of alternative AI models (e.g., DeepSeek, xAI's Grok 3) via its Azure AI Foundry, which does not involve revenue sharing with OpenAI, and internal efforts, led by Microsoft AI CEO Mustafa Suleyman, to develop proprietary models like Phi, potentially replacing OpenAI's. Microsoft has even listed OpenAI as a direct competitor, particularly as both entities target enterprise customers with their respective AI offerings, sometimes creating internal friction, as seen with OpenAI's GPT-4o release potentially undermining Microsoft's paid Azure services.

Key Decisions for Investors

• Investors should closely monitor developments in the Microsoft-OpenAI relationship, as any significant deterioration or public dispute could impact Microsoft's AI leadership perception and stock performance, similar to the volatility experienced during the November 2023 OpenAI leadership crisis.
• Evaluate the progress and adoption of Microsoft's independent AI initiatives, such as Azure AI Foundry and its proprietary small and large language models, as these represent crucial hedges against potential over-reliance on OpenAI and could offer diversified AI revenue streams.
• Factor in the increasing regulatory risk associated with Microsoft's AI investments, particularly the OpenAI partnership, as ongoing FTC investigations and potential antitrust allegations could lead to unfavorable outcomes, including possible modifications to the existing agreement or restrictions on future collaborations.
• Consider the competitive implications, noting that any weakening of the Microsoft-OpenAI alliance could create opportunities for competitors like Google, and assess how Microsoft's strategy to embrace rival AI models might mitigate this risk or alter its market positioning.
