Chinese RAM Maker CXMT Debuts at $484B Valuation

AI data centers are causing grid reliability problems not because of power generation shortages, but because their architecture doesn't match how modern electrical grids work. Two major outages in Virginia, including a July 2026 fault that knocked 3 gigawatts offline, exposed how AI campuses can swing 70% of their load in milliseconds, triggering protection systems designed for predictable industrial loads. The fix requires moving power conditioning from inside data halls to medium-voltage systems at substations, fundamentally changing how data centers connect to the grid.

SpaceX has reorganized its data center operations under a new team of rocket engineers, shifting toward a more cautious build approach that prioritizes redundancy and pre-deployment testing. The company is installing more backup systems for power and cooling upfront and reducing reliance on temporary infrastructure, a departure from the rapid deployment model used previously. This operational overhaul may slow the pace of new data center campus construction.

D-Matrix, an AI chip startup, announced it will integrate Nvidia's NVLink Fusion networking hardware to connect its chips and link them to Nvidia's Vera CPUs used in data centers. The partnership deepens Nvidia's ecosystem integration with specialized AI hardware makers. This move signals growing standardization around Nvidia's interconnect technology for multi-chip AI deployments.

OpenAI is collaborating with Samsung Electronics to develop next-generation chips, expanding an existing partnership that already includes data center and enterprise sales work. The move signals OpenAI's continued investment in semiconductor development as a core capability. Samsung's involvement deepens ties between the AI leader and a major hardware manufacturer.
