Tech and AI stocks suffered a sharp decline following US midterm election results, with the Nasdaq dropping over 5.5 percent and erasing approximately 2.5 trillion dollars in market value. Nvidia shares fell more than 9 percent, while AMD and Micron each dropped over 17 percent. Investors expressed concern that heavy spending on AI infrastructure may not yield expected returns and that new regulations could slow data center growth.
The sell-off intensified after Democrats won key races in states with significant data center presence, including Texas. Elon Musk's Tesla and SpaceX shares also tumbled, dropping 11 percent and 9 percent respectively. CoreWeave and Nebius saw their stock prices plunge sharply as well. Analysts note that while some view the drop as a buying opportunity, the market reaction reflects fears of stricter AI rules and potential grid constraints.
Chipmakers faced significant headwinds, with Intel shares falling over 18 percent over five days. Greg Brockman, president of OpenAI, stated the industry was caught off guard by the backlash to data center expansion. Meta's Dina Powell McCormick emphasized that tech companies must better explain the benefits of AI to the public to mitigate such volatility.
In response to security challenges, Absolute Security updated its Autonomous Cyber Resilience platform to support AI endpoint devices running Linux, alongside Windows, Chrome, and Mac. The update allows security teams to manage all AI devices from a single console, featuring device inventory, freeze capabilities, and patching for Ubuntu and Red Hat Enterprise Linux workstations.
Fleet expanded its device management capabilities to include NVIDIA RTX PRO workstations and DGX Station systems. The DGX Station utilizes the GB300 Grace Blackwell Ultra Desktop Superchip with 748GB of memory. This integration enables IT teams to track software, apply policies, and manage vulnerabilities on AI hardware alongside standard endpoints, reducing the need for separate management tools.
Researchers introduced MA-SafeDiffuser, an extension of SafeDiffuser designed for multiple agents. This system adds safety guarantees for joint-agent tasks using diffusion-based trajectory planning by embedding control barrier function constraints into denoising steps. Tests on a multi-agent Maze2D benchmark showed fewer safety violations compared to unconstrained diffusion methods.
Evan Ratliff, known as Husk, has gained industry attention for exposing flaws in major AI systems. His work involves publicly sharing weaknesses found in models from companies like OpenAI, Anthropic, and SpaceX. Major AI labs have reached out to collaborate with him, valuing his insights for improving system reliability.
Phoenix Security launched Green AI Remediation to reduce unnecessary AI token usage in security fixes. The tool allows teams to review findings and see cost estimates before any model runs, with pull requests opening only after authorization. ClearBank reported a 98 percent reduction in container vulnerabilities after using this context-based filtering approach.
Core Scientific warned of potential data center moratoriums in its September 2026 10-Q filing, noting that CoreWeave accounted for approximately 84 percent of its total revenue. The company controls about 2.6 GW of gross utility power across 11 data centers, with four sites in Texas facing curtailment risks during grid emergencies. As of September 30, the company reported roughly $4.4 billion in borrowed money.
India proposed new security audit rules requiring stricter oversight for AI systems from global providers like OpenAI and Anthropic. These regulations include mandatory kill switches for high-risk AI agents and a requirement to report incidents within six hours. The measures aim to increase safety and accountability for artificial intelligence operating within the country.

Tech and AI stock crash wipes out trillions after US midterms
Tech and AI stocks fell sharply after Democrats won key elections in states with many data centres. The Nasdaq dropped over 5.5 percent, wiping out about 2.5 trillion dollars in value. Nvidia fell more than 9 percent, while AMD and Micron each dropped over 17 percent. Elon Musk's SpaceX and Tesla shares also fell sharply. Investors worry that heavy spending on AI may not pay off and that new rules could slow data centre growth.
AI stock sell-off hits Nasdaq after US election results
The Nasdaq 100 fell 6.3 percent, erasing about 2.3 trillion US dollars in market value. Chipmakers and AI data centre companies sold off after Democrats won races in states like Texas. Nvidia shares fell 7 percent, and Elon Musk's Tesla and SpaceX shares dropped 11 and 9 percent. CoreWeave and Nebius also plunged sharply. Investors fear stricter AI rules and too much building of data centres, but some analysts see the drop as a chance to buy cheap stocks.
SpaceX and Tesla shares fall after Democrats win US midterms
Shares in Elon Musk's SpaceX fell over 7 percent and Tesla dropped over 9 percent after Democrats won the US midterms. Markets reacted to possible tougher rules on data centres and AI after Democrat wins in states like Texas. Chipmakers also suffered, with AMD down nearly 17 percent and Intel down over 18 percent over five days. OpenAI president Greg Brockman said the industry was caught off guard by backlash to data centres. Meta's Dina Powell McCormick said tech companies must do more to explain the benefits of AI.

CEO Brian Chesky said it will assist with reservations, payments, refunds, rebooking, and safety support. The tool draws on nearly 20 years of booking and hosting data from the platform. It will also provide help beyond the initial booking process.
DyPSI creates better physics sensing for changing environments
Researchers created DyPSI, a new framework for sensing physics in environments that change over time. This tool improves on older methods by generating future field predictions and sensor paths together instead of separately. It uses a shared representation and a diffusion model to work in a special latent space for better results. Tests on turbulent flow, sea-surface temperature, and car aerodynamics show DyPSI reduces errors significantly compared to static strategies.
