Microsoft has announced the integration of its CoPilot AI assistant into Windows 11, featuring voice activation capabilities. Users can now activate CoPilot by saying 'Hey, Copilot,' as part of Microsoft's strategy to enhance user experience and solidify its leadership in the AI sector. This move is complemented by significant AI-related acquisitions, including a $100 billion deal for CoreWeave and up to $19.4 billion for Nebius, aimed at securing GPU resources amid growing AI demand. The integration and acquisitions have positively impacted Microsoft's stock, which has risen 21% year-to-date. Analysts have set optimistic price targets for the company's stock, ranging from $520 to $650, reflecting strong investor confidence in Microsoft's AI initiatives.
