Amazon's shares rose 5.5% to $286.20, reaching a record high and bringing their yearly gains to over 23%. This surge follows strong earnings and signs that the AI boom is driving fresh demand for its cloud-computing services, which is the company's main profit engine. Amazon's stock had previously surged 15% on Friday after it reported its strongest cloud growth in over four years and raised its annual capital spending forecast. The company joins Apple, Microsoft, Alphabet, and Nvidia as companies that have recorded a market value of $3 trillion in the past.
