Big Tech's AI surge continues unabated. Artificial intelligence was front and center for the five leading tech giants, collectively valued at over $10 trillion, that reported their quarterly earnings this week. Executives from Apple (AAPL), Microsoft (MSFT), Alphabet (GOOG; GOOGL), Amazon (AMZN), and Meta (META) highlighted the advancements their companies have made in integrating AI into their operations and launching new AI features for consumers. They also addressed the strong demand for AI and the challenges faced in meeting that demand. Investors are now focused on the last of the Magnificent Seven companies to release its earnings: Nvidia (NVDA), which is set to report on November 20. Its stock reached an all-time high last month as investors anticipated that this week’s earnings would showcase significant demand for its AI chips. Spending on AI Infrastructure Is Soaring. . . This year, Big Tech's investments in infrastructure have soared. Cloud providers are in a race to enhance their AI capabilities and satisfy the booming demand for cloud services. In the third quarter, Microsoft, Alphabet, Amazon, and Meta collectively spent $60 billion on property and equipment, marking a 60% increase compared to last year, according to an analysis from Investopedia.

All four companies have indicated that their infrastructure investments will keep rising next year. The rising infrastructure costs had cast a shadow over tech giants during their previous earnings calls in July, when Wall Street was eager for signs that these investments were yielding results. However, concerns have somewhat eased following this week’s reports. . . . But Clouds Can't Expand Rapidly Enough A recurring theme from tech executives this week was their struggle to keep up with demand. On Wednesday, Microsoft cautioned that growth in its cloud division might slow in its second fiscal quarter. AI demand “continues to exceed our available capacity, ” noted CFO Amy Hood. Amazon CEO Andy Jassy echoed these sentiments on Thursday, stating that Amazon Web Services was also grappling with cloud computing demand. Jassy pointed out that a shortage of cutting-edge semiconductors was the primary constraint. AI's Growth Is Fueling Business Expansion Despite these capacity challenges, AI continues to propel growth for tech giants. Microsoft CEO Satya Nadella announced that the company’s AI sector is on track to achieve an annual revenue run rate of $10 billion this quarter, making it “the fastest-growing business in our history to reach this milestone. ” On Thursday, Jassy shared that Amazon’s AI division is expanding at triple-digit rates, significantly outpacing the early growth of its cloud computing services. Executives from Alphabet expressed optimism that AI investments would “translate into revenue in the relatively near future. ” They mentioned that monetization of AI Overviews in Google search was occurring “at approximately the same rate” as older formats, bolstering confidence that AI could enhance Alphabet’s core advertising business as well as its cloud operations. Meta also highlighted the advantages it is experiencing due to AI. CEO Mark Zuckerberg noted that AI-powered feed recommendations have increased user engagement on Facebook and Instagram this year, and businesses utilizing Meta’s generative AI advertising tools have observed a rise in conversion rates.
