US DOJ Escalates Antitrust Probe into NVIDIA with Subpoenas on Loyalty Penalties and Market Dominance

Uber announced a partnership with autonomous vehicle startup Motional to deploy commercial robotaxis in Las Vegas starting this year, marking a major expansion in US self-driving technology. The service will initially operate with safety drivers before progressing to fully driverless rides, integrating with Uber's ride-hailing app for seamless user access. This launch positions Las Vegas as a key testing ground for robotaxi scalability amid competition from Waymo and Cruise. Industry observers anticipate broader US rollouts by 2027 as regulatory hurdles ease under the Trump administration.

Meta Platforms is evaluating layoffs impacting at least 20% of its nearly 79,000 employees as of December 31, 2025, to counter escalating AI infrastructure expenses, according to a Reuters report on March 14, 2026. Top executives discussed the plans with senior leaders, marking potentially the largest restructuring since 21,000 job cuts in 2022-2023 if implemented. The move aligns with industry trends, as Amazon recently eliminated 30,000 roles citing AI-driven efficiencies. A Meta spokesperson dismissed the report as speculative on theoretical approaches, amid broader tech sector adjustments to AI economics.

America Makes and the National Center for Defense Manufacturing and Machining announced two project calls totaling over $35 million on March 5, 2026, funded by the U.S. Department of Defense to advance manufacturing technologies. The 2026 DOD OIB Modernization Challenge covers nine topics including AI Robotic Process Planning, Real-Time Manufacturing Sensors for Robotics, and In-Situ Quality Checks, aiming to reduce technical risks and enable transition pathways for defense applications. Proposals are due by April 2, 2026, for the OIB Challenge and April 29 for JAQS-SQ Groups 2 & 3, with kickoff webinars held on March 10 and 12. This funding supports U.S. industrial base resilience amid rising geopolitical tensions.

Microsoft is incorporating rack-scale NVIDIA Rubin systems into its 'Fairwater' AI superfactories to power advanced model training starting late 2026. This follows NVIDIA's Rubin unveiling, promising leaps in compute efficiency for cloud-scale AI. The move bolsters US AI infrastructure amid enterprise agent adoption rates surging in datacenters.

NVIDIA announced the Rubin platform, named after astronomer Vera Rubin, marking a shift from Blackwell with extreme co-design across six new chips targeting 1.6nm processes for massive computing power gains. First Rubin systems will launch in the second half of 2026 through AWS, Microsoft, and Google, with Microsoft integrating them into 'Fairwater' AI superfactories. This hardware leap supports edge-centric AI via specialized ASICs, enabling real-time insights, amid rising demand projected over $700 billion in global datacenter leases.

Negotiations between OpenAI and Oracle for expanding a massive datacenter in Abilene, Texas, as part of the $500 billion Stargate project, have stalled due to disagreements on financing and capacity delivery speed. The project aims to secure US AI leadership but faces headwinds in the global compute arms race with over $700 billion in datacenter lease volume, up 340%. Resolution could accelerate American AI infrastructure dominance amid bubble concerns.

Wall Street closed lower on Friday with all three major indexes ending the week in the red, while the Russell 2000 hit its lowest level of the year, despite strong corporate earnings and solid guidance reportedly supporting broader market trends.[3] Meta Platforms shares fell nearly 4% following a report that the social media giant has postponed the release of its AI model Avocado to at least May, signaling potential delays in the company's AI product roadmap.[3] Ulta Beauty shares slumped more than 14% as rising costs deepened margin concerns, with the company's new CEO flagging potential global cost impacts.[3] The mixed market performance reflects investor uncertainty about technology sector growth prospects amid ongoing economic and competitive pressures.

The US Commerce Department withdrew a planned rule on artificial-intelligence chip exports on Friday, marking the latest policy reversal by the Trump administration regarding technology trade controls.[4] The withdrawal represents a significant shift in the administration's approach to regulating AI semiconductor exports, which had been a contentious issue affecting companies like Nvidia and other chipmakers.[4] This decision follows earlier statements from administration officials indicating a more flexible stance on AI chip distribution policies compared to previous regulatory frameworks.[4] The reversal signals potential changes in how the US will manage competition with foreign nations in advanced semiconductor and AI technology sectors.

ByteDance is working with Aolani to deploy approximately 500 Nvidia Blackwell computing systems in Malaysia, comprising roughly 36,000 of Nvidia's most advanced B200 chips, according to reports citing people familiar with the matter.[1] The hardware deployment is valued at more than $2.5 billion and represents a significant effort by the Chinese tech giant to access top-tier AI processors despite US export restrictions.[1] ByteDance's AI portfolio includes Dola chatbot, Dreamina video creation tool, Gauth homework assistant, and Seedance video generation model, which has gained attention for its ability to convert written scripts into realistic short film scenes.[1] The move underscores ongoing tensions around US-China tech competition and export controls on advanced semiconductor technology.

Signal President Meredith Whittaker stated at the India Today Conclave 2026 that the conflict between the US Government and AI companies like Anthropic is far from over, asserting 'I don't actually think that showdown is decided yet.'[2] Whittaker explained that deployment of AI models on government systems creates dependency, and crucially, US law prevents the federal government from collecting the vast amounts of user data that private companies leverage to train AI systems.[2] She noted that the US government lacks legal authority to accumulate such datasets, stating: 'These are not technologies that the state could create. It doesn't matter how much money they have. It is not legal for the US government to collect the kind of data that the private industry can collect.'[2] The remarks reflect ongoing regulatory and operational tensions between government agencies and commercial AI developers.

Samsung announced at CES 2026 a vision to unify artificial intelligence across its entire device ecosystem, committing to integrate AI into new mobile devices, 4K and higher-resolution televisions, and home appliance lineups globally.[5] The company positioned these intelligent devices as AI companions designed to understand user context and routines, functioning beyond traditional 'smart' gadgets to anticipate user needs and quietly enable personalized experiences.[5] Samsung's latest televisions now feature Vision AI that analyzes content, user preferences, and viewing environments in real-time to automatically optimize picture and sound without manual adjustments, while home appliances transition from tools to true AI companions that master automated routines and reduce mental load of household chores.[5] The company is launching a new Galaxy S Series this month as part of what it calls a 'new era of intelligence' intended to be both powerful and effortless for consumers.
