iPronics Raises $125M Series B for Photonic AI Switches
Spanish deep-tech startup iPronics, a spin-off of the Technical University of Valencia, has closed a $125 million Series B round led by Maverick Silicon and Light Street Capital, with participation from Nvidia and other investors, bringing total funding to $177 million. The company develops optical circuit switches (OCS) for AI data centers, offering low latency and up to 50% power savings by replacing electrical interconnects with photonic ones. Its product, iPronics ONE, is already shipping to unnamed tier-one AI infrastructure providers. The new capital will fund hardware miniaturization and commercial expansion, including a new Silicon Valley office and a packaging line with Fabrinet. The round highlights Europe's strength in integrated photonics and the growing demand for optical networking in AI clusters.

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.

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.
