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 Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
US suspends Microsoft, Adobe from green card labor program
The U.S. Department of Labor announced the suspension of Microsoft and Adobe from its Permanent Labor Certification program, along with Cognizant, Infosys, Capgemini, Tata, Wipro, and HCL. Secretary Keith Sonderling cited active federal investigations for Microsoft and Adobe, and criticized the companies for allegedly taking jobs from American workers. Vice President JD Vance specifically accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft responded by defending its hiring practices, stating that the majority of its U.S. employees are Americans and that most H-1B petitions are for existing employees. The announcement was made during a White House summit on H-1B fraud, coinciding with President Trump honoring several tech CEOs with the National Medal of Science.
