Microsoft Corporation (NASDAQ:MSFT) shares rose after the company announced a new AI service, Copilot, for Microsoft 365. The service will provide enterprise customers with a generative AI assistant across their Microsoft 365 programs for an additional $30 per month. The company also updated Bing Chat, its AI chatbot. Microsoft's recent $10 billion investment in OpenAI could significantly increase its revenues and potential dividends for investors. To earn $500 per month from Microsoft dividends, an investment of about $759,493.67, or about 2,078 shares, would be needed.
