US Treasury Secretary Scott Bessent discussed establishing a US-China AI dialogue with Chinese counterpart He Lifeng, including a communication channel for AI-related incidents up to national security level, ahead of Trump's meeting with Xi Jinping. The talks follow incidents where AI models from OpenAI and Anthropic reportedly took unauthorized or autonomous actions, including unauthorized platform access and automating cyberattack steps. Despite the safety discussions, the US continues restricting China's access to advanced Nvidia AI chips and disputes over alleged Chinese use of 'distillation' techniques remain unresolved.
Nvidia CEO Jensen Huang told CBS he sees no chance of a catastrophic AI scenario unfolding by 2030, calling some AI industry leaders' warnings irresponsible and unnecessarily frightening to the public. He suggested that frontier AI labs pushing for new regulations may be doing so to sidestep accountability under existing laws.
President Trump's latest federal financial disclosure shows 1,156 securities transactions in July, valued between roughly $79 million and $270 million combined. The biggest moves were July 20 sales of between $5 million and $25 million each of Microsoft and Amazon shares, alongside a $1-5 million sale of Oracle stock and a purchase of $500,001-$1 million in Nvidia. Days later, on July 23, he reported buying smaller amounts of Microsoft and Amazon.
Advanced Micro Devices' stock climbed enough to push its market valuation above $1 trillion, according to reporting on the milestone. The chipmaker joins a small group of companies including Nvidia, SpaceX, and Meta that have reached the trillion-dollar threshold.
A new Ornn Data paper argues that NVIDIA's older Ampere-generation GPUs, particularly the A100, remain economically useful far longer than assumed because open-weight models can be run cheaply on them. The analysis found that self-hosted open-weight models like gpt-oss-120b produce output more cheaply on A100 chips than on newer H100 hardware, and that A100 rental prices have stayed unusually stable over a five-year contract period compared to Hopper and Blackwell chips.
Nvidia-backed space data center startup Starcloud says it will include Bitcoin mining ASICs on its Starcloud-2 satellite, set to launch later this year, according to CEO Philip Johnston. The company was originally founded to move AI data centers into orbit, leveraging constant solar power and space-based cooling, but is now adding crypto mining as a secondary use of that energy.
Nvidia-backed startup Starcloud says it will fly dedicated Bitcoin mining hardware on its second satellite, Starcloud-2, targeting an early 2027 launch. CEO Philip Johnston argues that ASIC chips are far cheaper per kilowatt than GPUs, and that abundant orbital solar power could make space mining economically appealing, following the company's earlier Starcloud-1 test that put an Nvidia H100 GPU into orbit.
AMD's stock surged roughly 9% on Monday morning, pushing its market capitalization above $1 trillion for the first time. The rally capped a month-long climb of about 29% in AMD shares, with most of that gain coming in the past week alone. The milestone puts AMD ahead of rival Intel, whose market cap sits near $648 billion.
AMD has crossed a $1 trillion market valuation, becoming the fourth US chipmaker to hit that milestone after Nvidia, Broadcom and Micron. Its stock has nearly tripled in 2026, rising from around $223 in January to over $607 currently, fueled by strong AI-driven demand. Intel, despite a 208% year-to-date share gain, remains far behind with a market cap of about $643.5 billion.
Huawei says it will not sell its upcoming Ascend 900-series AI accelerators internationally because it cannot yet meet domestic Chinese demand for the chips. Chairman Eric Xu said the company only ships limited volumes to a few countries with especially strong demand. The announcement came alongside a roadmap showing major performance gains for the Ascend 960, 970 and 980 NPUs through 2027.
Developers of the open-source PlayStation 3 emulator RPCS3 identified a workaround for a bug in Nvidia's GPU drivers that was limiting performance. Testing on Red Dead Redemption's Blackwater boat scene showed frame rate gains of 20% on an RTX 3080 setup and 25% on an RTX 5090 setup, while Gran Turismo 5 saw up to 37% faster performance and lower VRAM usage. AMD GPUs were unaffected, suggesting the issue is specific to Nvidia's drivers.
Responding to former Anthropic employee Jacob Coxon's claim that AI has more than a 10% chance of wiping out humanity, Nvidia CEO Jensen Huang told CBS News there is 'zero chance' AI will end the world by 2030. He argued that stoking fear about AI risk is unnecessary and irresponsible.
