On August 18, Microsoft fell 3.1% in regular trading, trading at $480.05/share, with turnover of $5.761 billion. Multiple negative catalysts converged to pressure the stock.

On the news front, OpenAI recently slashed pricing for its GPT-5.6 Luna model by 80% to counter competition from lower-cost Chinese AI models, igniting an industry-wide price war. The market is increasingly concerned that Microsoft's AI monetization outlook through its OpenAI partnership may be impaired by intensifying pricing competition. Separately, Microsoft has reportedly been pursuing a strategic contraction of its China operations, closing at least 15 branch offices over the past five years.

Adding to investor unease, an investigative report revealed that Microsoft's actual installed AI chip count stands at approximately 2.2 million units — significantly below expectations relative to its roughly $280 billion infrastructure spending since 2022, raising questions about capital deployment efficiency. While multiple investment banks recently raised price targets to the $625–$700 range citing Azure's 43% revenue growth acceleration, near-term AI pricing headwinds and sector rotation into hardware names continue to suppress valuations.
