Microsoft Director Purchases Billions in Stock Amid Surge in AI Investment, Key Executives Sell and Handle Tax Payments

Microsoft Corp (MSFT) director John W. Stanton purchased 5,000 shares of the company’s stock on the open market on February 18, investing about USD 2 million (approximately KRW 2.7 billion) of his own funds to boost his direct holding.

By contrast, Kathleen T. Hogan, Vice President of Strategy, sold roughly USD 5 million (around KRW 7 billion) worth of shares on March 6 to realize part of her stake, while Judson Althoff, President of Commercial Business, had approximately USD 1.34 million (about KRW 1.8 billion) of shares withheld on March 2 to cover taxes on equity compensation, adjusting his ownership accordingly.

Despite robust cloud and AI growth in its latest quarterly results, Microsoft’s share price has experienced volatility amid concerns over a USD 37.5 billion quarterly capital expenditure and a deceleration in Azure growth.

Meanwhile, paid seats for Microsoft 365 Copilot have surpassed 15 million. The adoption of third-party models and the launch of new AI productivity tools—such as Copilot Cowork—are accelerating AI integration across the company’s productivity software portfolio.

As a global tech leader generating roughly USD 300 billion in annual revenue—anchored by Windows, Office and Azure—Microsoft is making substantial investments in its generative AI platform strategy centered on Copilot.
