↑ 0%Microsoft announced it will allow every US school district to set its own AI privacy and safety rules in their contracts. The move comes days after New York City imposed a one-year moratorium on AI in public schools. The "National AI Safety & Privacy Standard", announced by Microsoft Vice Chair Brad Smith alongside teachers' union leaders, becomes legally enforceable when written into district agreements. It prohibits using student data to train AI models, tracking students, and allowing AI to make decisions without human review. The protections take effect on 1 November for all school districts working with Microsoft, whether or not they actively adopt them. Districts can cancel contracts and seek damages if companies violate the rules. Union leaders said they hope OpenAI and Anthropic will sign similar agreements. Both companies have expressed willingness but haven't confirmed.
Amazon, Meta, Microsoft, Alphabet and Oracle — collectively dubbed the "Hyper 5" — have spent $1.1 trillion on capital expenditures over the past five years to build AI infrastructure, according to S&P Global Market Intelligence. Analyst estimates project another $5.3 trillion in spending through 2030. The investment surge is putting pressure on free cash flow. Amazon's free cash flow fell to negative $7.6 billion over the 12 months ended 30 June, from positive $18.2 billion a year earlier. Meta's second-quarter free cash flow dropped 91% to $784 million. S&P Global warns the key risk is companies transitioning from cash to debt-funded investment before returns validate the spending. However, the tech giants remain highly profitable, distinguishing this cycle from the dot-com boom.
Microsoft's Outlook and Exchange Online services experienced a widespread outage on 31 August, with over 6,000 reports on Downdetector. Microsoft said users may experience degraded functionality whilst it reviewed service telemetry. On the same day, OpenAI's ChatGPT Work suffered a separate three-hour outage. There were no reports connecting the two incidents, though Microsoft and OpenAI remain closely tied through Microsoft's investment and Azure infrastructure support. Microsoft reported record fourth-quarter revenue of $90.01 billion, up 18% year over year. Azure revenue surpassed $100 billion annually after growing 43% in the quarter. Commercial remaining performance obligations jumped 84% to $678 billion. Microsoft 365 Copilot surpassed 30 million paid seats, with net seat additions more than doubling sequentially.
Microsoft CEO Satya Nadella sold approximately $43 million worth of company stock, but the transaction should not be interpreted as a bearish signal. The sale of 86,525 shares on 1 September was executed under a pre-arranged Rule 10b5-1 trading plan adopted on 8 March 2026, designed to sell shares tied to a performance-stock award. Microsoft's fundamentals remain robust. Fiscal fourth-quarter revenue increased 18% to $90 billion, whilst net income rose 31% to $35.8 billion. Azure and cloud services revenue jumped, with Microsoft Cloud revenue climbing 27% to $59.3 billion. The company added 31 new data centres during the latest quarter as part of aggressive AI infrastructure investments. Commercial remaining performance obligations surged 84% to $678 billion, providing substantial future revenue visibility.
Laurent Sifre, cofounder of Paris-based agentic AI startup H Company, has joined Microsoft, Sifted has learnt. The move sees Sifre transition from the French AI startup to the US tech giant. H Company focuses on agentic AI technology. No further details about Sifre's role at Microsoft or the circumstances of his departure from H Company were disclosed.
