Investor interest in Microsoft shares may have weakened in recent months, but the company posted strong financial results on Wednesday which yet again demonstrated that the AI boom is roaring on. Three months ago, it beat analysts’ revenue expectations by 2.9%, reporting revenues up 18.4% year on year. On Wednesday, Microsoft said Azure revenues grew 39%, compared with 40% growth in the fiscal first quarter. “Microsoft Cloud revenue crossed $50bn this quarter, reflecting the strong demand for our portfolio of services,” said Amy Hood, executive vice-president and chief financial officer of Microsoft. The most recent US productivity report showed strong gains without increased work- hours, suggesting that the gains could be attributed to AI.
