Microsoft and Google's recent quarterly earnings have significantly surpassed expectations, driven largely by their investments in artificial intelligence (AI). Microsoft reported a 20% increase in profits, reaching nearly $22 billion, with revenue up 17% to $61.9 billion, attributed to strong cloud and AI accelerator sales. Microsoft's cloud AI demand has exceeded supply despite increased spending. Similarly, Google's parent company, Alphabet, saw its shares surge by over 11% after announcing a $70 billion buyback and its first-ever cash dividend for investors, following a robust earnings report. These financial successes underscore the tech giants' strategic focus on AI, which has already begun to substantially boost their financial performance. Google's market cap has reached $2 trillion, marking a significant milestone.
