Four of the Magnificent Seven (Mag 7) tech giants are still on track to meet their massive artificial intelligence (AI) spending targets this year, according to their earnings report. The companies that have reported quarterly earnings post-market on Wednesday are Microsoft (MSFT), Alphabet (GOOG), Meta (META) and Amazon (AMZ), with a combined market cap of approximately $12 trillion. Previously, an analysis by Bridgewater Associates flagged that the four companies are expected to spend roughly $650 billion together on AI infrastructure in 2026. While most of them didn't break out their AI spending in their latest earnings, they seem on track to continue their spending spree in the sector. The investment has significant implications for the digital asset sector, particularly for bitcoin miners, who are increasingly pivoting away from mining toward hosting computers for AI as part of their revenue diversification strategy. The bitcoin miners already have data centers ready and powered up to host a massive amount of machines that are needed for AI computing. Facing a margin squeeze from lower bitcoin prices and increased competition, miners have started lending their data centers to AI firms to diversify their revenue streams. AI-linked bitcoin mining stocks with exposure to hyperscaler infrastructure deals include IREN (IREN), which was down about 0.3%, TeraWulf (WULF) and Cipher Digital (CIFR), which fell 0.5%. Meanwhile, following the results, Microsoft was down over about 2.4% in after-hours trading, Alphabet up 6%, Meta down 6.6% and Amazon down 3.7%. Bitcoin was down about 0.9% in the last 24 hours. The next big test of overall market sentiment and miners will come when chipmaker Nvidia reports earnings on May 20. Here is what the tech giants reported and said during their earnings. Microsoft reported fiscal Q3 2026 revenue of $82.9 billion, beating the $81.4 billion consensus, with EPS of $4.27 against the $4.06 estimate, according to FactSet data.
