Microsoft's AI Business Hits $37 Billion Annual Run Rate

Key Takeaways

Better questions lead to better security

Organizations need to ask better questions to achieve better security. This involves combining intelligence and trust to protect data and build resilience. Security is not separate from innovation; it enables responsible innovation. AI is changing how security decisions are made, providing access to more signals, insights, and analytical power. The right questions to ask include what to protect, what risks matter, and what decisions need to be made with confidence.

AI inventory: key to securing AI tools

Organizations need to identify, catalog, and monitor AI applications, agents, models, and AI-enabled software operating on their endpoints. This visibility gap has created a new security challenge: securing AI without visibility is not possible. A comprehensive AI inventory should help organizations answer questions such as which AI applications are installed or actively used and what data may be exposed to AI systems.

Microsoft vs Palantir: AI stock comparison

Microsoft and Palantir are two AI stocks with different approaches. Microsoft's AI business reached a $37 billion annual run rate, up 123% year-over-year. Palantir's U.S. commercial revenue surged 133%. The two companies have different valuations, with Palantir trading at 173x earnings multiple.

Microsoft Q4 earnings: AI investment payoff

Microsoft's Q4 earnings report is expected to show a strong performance, driven by its AI investments. The company's AI business reached a $37 billion annual run rate. Analysts expect EPS of about $4.21–$4.24 and revenue near $87.7B, up roughly 15% year-over-year.

Large language model for operations research

Researchers propose a solver-guided large language model (LLM) framework for operations research formulation selection. The framework constructs balanced expert-conditioned supervised fine-tuning records and uses MIP solver evaluation on historical instances to convert allocation-quality gaps into margin-weighted identity preference optimization preferences.

Bloom Energy poised for AI-driven growth

Bloom Energy is well-positioned to capitalize on the growing need for clean energy solutions driven by AI. According to Goldman Sachs, U.S. data center power demand could more than double from 31 gigawatts in 2025 to 66 gigawatts by 2027.

Corporate Taste: key asset in AI transformation

Corporate Taste refers to a company's collective judgment, domain expertise, and the wisdom to discern what to build and what not to build. This asset is hard to protect as it resides in employees' minds and can depart with them. Organizations must recognize its value, document judgment, and transfer it through apprenticeship and exposure.

Agent skills matter in AI

Researchers introduce SigLeak, a black-box framework that exploits recurring skill signatures in agent behavior. SigLeak outperforms or matches three baselines in nearly every setting, raising the success rate by 6.88 percentage points over the skill-disabled reference.

AI agents broaden knowledge work scope

AI agents don't just speed up knowledge work; they change its nature. In a field study of Perplexity's conversational assistant and autonomous agent, researchers found that the agent performed more autonomous work, cut task time, lowered cost, and left users more satisfied.

Insider selling at Nvidia and CoreWeave

Executives and investors tied to the AI supply chain, including Nvidia and CoreWeave, sold a combined $1.4 billion worth of stock in the second quarter. The sales by insiders are a sign that some of the people closest to the companies are cashing out on the boom.

ChatGPT approaches 1 billion users

ChatGPT is approaching 1 billion weekly active users, a milestone achieved by few apps in history. The growth is driven by its popularity among clients, with over 50 million paying subscribers.
