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.

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.
