   Burry shorts Caterpillar as AI data-center demand fuels stock debate

   Investor Michael Burry has expanded his short position in Caterpillar (CAT) alongside other tech names, according to social media discussions, as part of a broader bet against AI-related momentum. Meanwhile, traders are flagging aggressive call purchases and unusual options volume in CAT contracts, suggesting positioning for potential upside. Caterpillar's power generation equipment is seeing record demand tied to AI infrastructure projects, with analysts citing a record backlog and infrastructure spending as key supports. However, some warn that cyclical risks in construction and mining could offset these gains. Insiders have sold heavily—46 insider trades in the past 6 months consisted of 45 sales versus 1 purchase—even as Q1 2026 revenues reached $17.4B, up 22.22% year-over-year.

   Wall Street analysts remain broadly bullish, with 3 firms issuing buy or overweight ratings and 0 sell ratings in recent months. The median analyst price target stands at $878.0, though individual targets range widely—from $845.0 to $1218.0—reflecting divided views on execution risks versus growth opportunities in AI-driven infrastructure demand.

   Microsoft launches AI-powered cybersecurity tools

   Microsoft has unveiled a suite of artificial intelligence-powered cybersecurity tools designed to help organizations detect and respond to threats. Cybersecurity threats are increasing in sophistication, and AI can help organizations identify and defend against attacks faster than manual methods alone.

   Availability details, pricing, and which Microsoft products will integrate these new AI security capabilities.

   Texas firm sues Micron over AI chip memory tech in Idaho trial

   CrossLake Intellectual Properties, a Texas-based firm, brought a lawsuit against Micron Technology, claiming the company stole intellectual property related to memory technology used in AI systems. The case is being heard by a jury in Idaho, where Micron is headquartered. Memory technology is a critical component powering AI infrastructure and data centers. If CrossLake's claims are upheld, it could reshape how companies license foundational AI hardware technology and potentially expose Micron to significant liability in a market central to the AI boom.

   The jury's verdict will determine whether Micron is found liable for intellectual property theft and could establish precedent for how memory-technology patents are enforced in the AI hardware sector.

   Netflix Details In-House LLM Serving Platform Built on Triton and vLLM

   Netflix published technical details on how it built an internal platform to serve large language model (LLM) inference—the step where an AI produces an answer—combining its existing JVM-based serving layer with Triton for model management and vLLM for inference execution. Smaller models run directly on CPUs, while larger requests route to a dedicated serving system where Triton handles scheduling and multi-framework support. The platform reveals the operational complexity of running AI models at scale. Netflix encountered specific challenges—mismatched software versions preventing deployments, custom models exceeding standard compatibility, and state management during paused requests—that required engineering solutions at multiple layers. This shows that even with standardized APIs, production LLM serving demands careful integration work across different engines and hardware.

   Netflix opted for vLLM's backend over Triton's Python backend because it allows models and interfaces to evolve more independently. The company also pins tested versions of Triton and vLLM together to prevent failures, and uses Versioned deployment strategies to let teams migrate at their own pace when model schemas change.

   Microsoft introduces Project Perception, agentic security system for AI-driven threats

   Microsoft unveiled Project Perception, a new security system that uses AI agents to continuously detect, evaluate, and counter threats at machine speed. The system enters public preview on August 3 and coordinates three classes of specialized agents—red team (identifying attack paths), blue team (assessing risk), and green team (taking corrective actions)—into a closed-loop defense loop. Traditional security approaches built for human-speed attacks cannot keep pace with AI-powered threats that generate exploits faster and operate with unprecedented efficiency. Project Perception addresses this by applying specialized AI models to specific security tasks rather than relying on a single model, achieving 96% on CyberGym (an industry leading benchmark) for software vulnerability management while delivering almost 50% cost savings compared to the current configuration in market today.

   The system uses a multi-model architecture that selects the right AI model for each task, optimizing for quality and cost. Microsoft's specialized model MAI-Cyber-1-Flash, integrated into MDASH (a software vulnerability multi-model team of agents), scored 12 points above Mythos on CyberGym; the company plans to expand this model's use across additional security workflows beyond software vulnerability management.

   Apple poised to profit as AI bubble bursts, says critic Ed Zitron

   Ed Zitron, a longtime skeptic of AI economics, argues that the large language model industry is fundamentally unprofitable—OpenAI lost $20.9 billion（約3.3兆円） on $13.07 billion（約2.1兆円） in revenue in 2025—and that the data center buildout driving recent hardware price increases will never generate returns. Memory prices have roughly doubled this year, pushing up costs for Macs, iPads, and soon iPhones. Hyperscalers have spent over $1 trillion（約160兆円） in capex since 2022, with over $650 billion（約100兆円） allocated to AI infrastructure this year alone. If the bubble collapses, the contagion will ripple through pension funds, semiconductor makers, and Taiwanese and Korean suppliers—but Apple, having spent only about $14 billion（約2.2兆円） and outsourced AI to Google (paying roughly a billion a year for Gemini), is positioned to sidestep the damage. Consumers, meanwhile, are already bearing the cost through higher hardware prices.

   Zitron predicts Apple will "sit on the sidelines and watch everything burn" while potentially making acquisitions as valuations crater. He also highlights Apple's Vision Pro as the company's more promising long-term bet, though he notes the device released too early and currently requires a full-time wear update to function properly.
