xAI to Buy $18B in Nvidia Chips for Colossus 2
Elon Musk's AI company xAI is expanding its computing infrastructure with a second massive data center, Colossus 2, near Memphis, Tennessee. The project involves the purchase of 300,000 additional Nvidia chips at a cost of at least $18 billion. The data center is expected to eventually house up to 550,000 chips, with potential to reach one million. Total investment could reach $40-50 billion, according to local chamber estimates. xAI recently raised $10 billion in early 2025, with SpaceX contributing $2 billion. The expansion has raised environmental concerns, including emissions from natural gas turbines and water usage, but local officials see it as an economic boost.
Major AI infrastructure investment by xAI significantly expands compute capacity, affecting the AI ecosystem and its use in advertising and marketing.

Fed Sees AI Boom as Inflation Driver
The Federal Reserve has identified the massive expansion of AI infrastructure as a contributing factor to persistent inflation, according to the minutes of its latest interest rate meeting. The Fed raised its benchmark interest rate for the first time since 2023, and the minutes reveal that committee members observed that 'strongly rising AI-related investments' are adding to inflationary pressures. While tariffs and energy prices remain significant factors, the AI boom is also supporting the economy through robust corporate investment. The report highlights that the Fed's preferred PCE inflation measure rose to 3.8% in August, with core inflation at 3.4%, well above the 2% target. A majority of members consider it likely appropriate to raise rates again by the end of the year, depending on incoming data. The role of AI as a primary driver of core goods prices is noted by 'several' members, not a majority, indicating a nuanced view.
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.
