Nvidia Bets $26B on Open-Source AI to Defend CUDA Moat
Nvidia announced a $26 billion investment over five years to develop open-weight AI models, the largest such bet in history. The company released Nemotron 3 Super, a 120-billion-parameter model optimized for AI agents, featuring a novel Latent MoE architecture and native NVFP4 4-bit training. The model claims significantly higher throughput than OpenAI's GPT-OSS 120B and Alibaba's Qwen3.5-122B. Nvidia's strategy mirrors Google's Android approach: open models to lock developers into its hardware. However, the move risks alienating hyperscalers like Microsoft, Amazon, Google, and Meta, who are both customers and competitors. The article notes Nvidia's CUDA ecosystem faces pressure from AMD and OpenAI's Triton compiler, with Nvidia's data center GPU share declining from 90% to 86%.
Nvidia's $26B open-source AI bet and Nemotron 3 Super release could reshape the AI model landscape, intensify competition with hyperscalers, and significantly influence the adoption of open-weight models across industries.

AI Stocks Sink as OpenAI Revenue Misses Reported Figure
Shares of Nvidia, Oracle, CoreWeave and other AI-related companies fell on Thursday after details emerged about OpenAI's revenue. OpenAI told investors it reached roughly $50 billion in annualized revenue at the end of September, lower than the widely reported $68 billion figure. A person familiar with the matter said the $68 billion figure included gross revenue from partners, making it more comparable to Anthropic. OpenAI also highlighted 77% total run rate growth in Q3 and 107% growth in enterprise business. The company is preparing for a potential IPO, with a valuation of $852 billion, and is in early talks to raise around $30 billion in new funding.
US suspends Microsoft, Adobe from green card labor program
The Trump administration has suspended Microsoft, Adobe, and six other major tech firms—Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro—from the U.S. Permanent Labor Certification program, which facilitates green cards for skilled foreign workers. Secretary of Labor Keith Sonderling cited active federal investigations and alleged fraud, noting that no new or pending applications from these companies will be accepted. Vice President JD Vance accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft defended its practices, stating that most U.S. employees are American and that 80% of its H-1B petitions were for existing employees. The announcement was made during a White House summit on H-1B fraud, and the administration also plans to investigate nine universities, including Harvard, Yale, and Stanford, over student visa program abuse.
Musk's Grok Bot to Use Rival AI Models Like Claude
Elon Musk announced that Grok Bot, an agent app from his AI unit (formerly xAI, now part of SpaceX and recently renamed SpaceXAI/SpaceXSI), will no longer rely solely on its own Grok models. Instead, it will pick 'the best back-end model for the respective task,' citing examples such as Anthropic's Claude Opus 5.5, Midjourney, and Suno. The announcement, first reported by The Information, follows user complaints about access issues. This strategic shift acknowledges that xAI's models don't lead in all areas—for instance, Claude Opus 5.5 outperforms competitors on the Artificial Analysis ranking. The move mirrors a broader industry trend of multi-model routing, as seen with Microsoft's Copilot and Perplexity, and comes despite reports of SpaceX planning $40 billion in debt for Nvidia chips.
