Microsoft (MSFT.US) has invested over $100 billion in its partnership with OpenAI, a figure that underscores the software giant's pivotal role in the artificial intelligence company's growth trajectory. In testimony on Monday, a Microsoft executive stated that this amount includes the company's initial investment in OpenAI, as well as the costs associated with building the infrastructure and hosting the computational power required by OpenAI. He clarified that this is a cumulative figure through the current fiscal year ending in June, with many of these costs incurred before any revenue was generated. "We had to build out the Azure infrastructure before we could provide these services to OpenAI," he said, referring to Microsoft's cloud computing division. The testimony was part of a high-profile lawsuit in federal court in Oakland, California, where Elon Musk is suing OpenAI and Microsoft. In the lawsuit filed in 2024, Musk alleges that OpenAI co-founders Sam Altman and Greg Brockman abandoned the startup's founding mission as a non-profit organization dedicated to benefiting humanity, shifting instead to operate as a for-profit entity. The world's richest person also claims Microsoft facilitated this alleged betrayal. Microsoft had invested approximately $13 billion in ChatGPT developer OpenAI by early 2023 and has been its primary cloud infrastructure provider. Last week, Microsoft CEO Satya Nadella stated that the company aims for a $92 billion return from its early, substantial investment in OpenAI. Nadella, during his testimony, said these investments "worked out well because we took the risk." Faced with such massive capital deployment, the market is reassessing the capital efficiency and return on investment for tech behemoths like Microsoft. While the construction of super-scale data centers has placed significant pressure on Microsoft's free cash flow and net profit margins in the near term, the resulting commercialization has been exceptionally lucrative. It is reported that Microsoft has generated approximately $30 billion in robust revenue from businesses deeply integrated with OpenAI's technology, achieving a commercial cycle of "ultra-high investment for ultra-high growth." This outcome provides a significant confidence boost to Wall Street, which has been shadowed by concerns over an "AI bubble." More notably for investors, as OpenAI actively prepares for an initial public offering (IPO) slated for late 2026, its latest market valuation has surged to around $852 billion, with expectations of reaching a trillion-dollar valuation. This means that, based on Microsoft's current 26.79% stake, the book value of the equity it originally acquired through "computational power investment" has ballooned to between $135 billion and $228 billion. However, the revelation of this hundred-billion-dollar investment coincides with a major realignment in the global AI cloud market. Due to increasingly stringent antitrust scrutiny and high cost-sharing pressures faced by both companies, OpenAI and Microsoft recently renegotiated their cooperation agreement, formally ending their previous exclusive, single-vendor arrangement. As a critical step toward independent development, OpenAI subsequently signed an 8-year, $100 billion diversified cloud services contract with Amazon Web Services (AWS). While this move significantly alleviates the downward pressure on Microsoft's stock price caused by heavy capital expenditure, it also means Microsoft has relinquished absolute monopoly over the most advanced AI technology. With the strong entry of Amazon AWS and Google Cloud, the AI cloud market has decisively shifted from a past era of "exclusive binding" to a new competitive phase characterized by "multi-cloud and multi-polarization." To mitigate the risk of a potential technological gap in the "post-OpenAI era," a proactive Microsoft has begun actively engaging with other AI startups to explore alternative plans. The company aims to further reduce its absolute dependence on a single partner before the technological红利 (红利 translates to "dividend" or "benefit" in this context, implying the period of peak advantage) wanes. This strategic shift further complicates the battle for market share among the world's three leading cloud giants.
