Palantir Nvidia Develop Market Fears While Amazon AMD Develop Concerns

Global stock markets experienced a significant downturn around November 5, 2025, driven by escalating concerns over the high valuations of artificial intelligence and tech companies. The tech-heavy Nasdaq Composite saw its worst day since April, dropping 2.1%, while the S&P 500 also declined over 1%. This sell-off impacted major players worldwide, with U.S. tech giants like Palantir, Nvidia, AMD, Amazon, and Oracle experiencing stock drops. Asian markets were also hit hard, with Samsung, SK Hynix, Taiwan Semiconductor Manufacturing Co., and SoftBank, a major AI investor, seeing significant declines, SoftBank plunging over 10%. Noted investor Michael Burry, famous for predicting the 2008 financial crisis, placed a substantial $1.1 billion bet against AI-related stocks, including Nvidia and Palantir, further fueling "AI bubble" fears. CEOs from Goldman Sachs, Morgan Stanley, and JP Morgan Chase warned of a potential market correction, predicting a 10% to 20% drawdown in the next 12 to 24 months. Even Bitcoin fell below $100,000 for the first time since June, as investors moved away from perceived risky assets. This market uncertainty was compounded by central banks signaling slower interest rate cuts and IBM announcing workforce reductions, alongside an ongoing U.S. government shutdown. Despite these market jitters, the development and application of AI continue to advance across various sectors. Microsoft CEO Satya Nadella highlighted a critical bottleneck for AI growth: not a shortage of computer chips, but a lack of power and data center space. He noted that building new data centers capable of hundreds of megawatts can take years, potentially impacting chipmakers like Nvidia. In cybersecurity, Zscaler acquired SPLX, an AI security specialist founded in 2023, to bolster its Zero Trust Exchange platform. This acquisition adds a dedicated AI protection layer, offering advanced features like automated red-teaming with over 5,000 attack simulations to secure the entire AI lifecycle. Similarly, Barracuda Networks launched Barracuda Assistant, an AI-powered tool integrated into its BarracudaONE platform, designed to simplify threat detection, investigation, and response for businesses and managed service providers. AI adoption is also expanding rapidly. Production companies are integrating generative AI tools into their workflows. Firms like Impel in New York City are providing custom AI solutions for auto dealerships to create customer profiles, while San Francisco-based Forethought offers AI customer support, demonstrating immediate time and resource savings. Grammarly, also based in San Francisco, continues to serve 50,000 organizations and 40 million daily users with its AI writing assistant. Pinterest CEO Bill Ready praised open-source AI models for their "tremendous performance" and significant cost savings, using them for personalized recommendations, visual search, and its new AI-powered Pinterest Assistant, and is exploring agentic shopping through its Amazon partnership. Looking to the future, the U.S. Air Force is considering a recommendation for its B-21 Raider stealth bomber to fly with a single pilot and an AI co-pilot, showcasing advanced automation capabilities. In robotics, Chinese startup AgiBot is training two-armed robots for manufacturing tasks using a combination of human teleoperation and AI-driven reinforcement learning, enabling new task training in about ten minutes. Meanwhile, Google DeepMind is proactively addressing the broader societal implications of advanced AI by hiring a Senior AI Economist to study how AGI could reshape the economy, focusing on "scarcity, wealth, and distribution."

Production Companies Embrace Generative AI Tools

Production companies are now using generative artificial intelligence as a new tool. They have added this technology to their existing resources. This shows how the industry is adapting to new AI capabilities. The shift helps them improve their work processes.

AI Growth Faces Power Shortage Challenge

Microsoft CEO Satya Nadella revealed that the biggest challenge for artificial intelligence growth is a shortage of power and data center space, not a lack of computer chips. He explained that even with billions invested in chips, companies struggle to find "warm shells" to plug them into. Building new data centers that require hundreds of megawatts of power can take years, much longer than developing new AI models. This bottleneck means that future AI investment success might depend more on securing power and infrastructure quickly than on simply buying more chips. This issue could also negatively impact chipmakers like Nvidia.

Companies Help Businesses Adopt AI Easily

Many businesses feel they are behind on artificial intelligence, but new companies offer custom AI solutions to help them catch up. Impel, a New York City firm, uses AI to create customer profiles for auto dealerships, helping salespeople identify promising leads and automate tasks. Forethought, based in San Francisco, provides AI customer support solutions and guides clients through adoption, showing immediate time and resource savings. Grammarly, another San Francisco company, offers an AI writing assistant used by 50,000 organizations and 40 million daily users to improve communications. These firms aim to make AI accessible and beneficial for all businesses.

Google DeepMind Hires Economist to Study AI's Economic Future

Pinterest plans to use more open source AI for its visual AI applications. The company also explores agentic shopping, where AI could act on behalf of users, building on its existing Amazon partnership.

B-21 Raider May Fly With One Pilot and AI Co-Pilot

The U.S. Air Force is considering a recommendation for its new B-21 Raider stealth bomber to fly with just one pilot and one weapon systems officer, hinting at advanced AI capabilities. The B-21 was designed with cutting-edge automation, including an AI agent acting as a "co-pilot." This recommendation, still awaiting a final decision, acknowledges the bomber's complex mission requirements, which extend beyond traditional bombing. While a weapon systems officer adds crucial skills, having only one pilot raises safety questions for long missions, especially since older bombers like the B-2 Spirit use two pilots.

Chinese Startup AgiBot Trains Robots with AI and Humans

AgiBot, a Chinese robotics company, is teaching two-armed robots to perform manufacturing tasks using a combination of human training and artificial intelligence. Their system, which uses teleoperation and reinforcement learning, is currently being tested on a Longcheer Technology production line. AgiBot's Real-World Reinforcement Learning software can train a robot for a new task in about ten minutes, a crucial speed for changing factory environments. This method, however, requires a "small army" of human workers to guide the robots initially. Experts believe AgiBot's cutting-edge techniques will reliably automate tasks, potentially increasing manufacturing productivity and creating new job types.
