iPronics Raises $125M Series B, Nvidia Invests in Optical Switches
Spanish startup iPronics, a spin-off of the Technical University of Valencia, announced a $125 million Series B funding round led by Maverick Silicon and Light Street Capital, with Nvidia participating. The company has now raised $177 million in total. iPronics develops the iPronics ONE, an optical circuit switch (OCS) that routes data in data centers entirely via light, reducing latency and energy consumption by up to 50% compared to traditional switching. The technology, inspired by Google's use of OCS in TPU clusters, aims to solve network bottleneck issues in AI supercomputing. The funds will be used to miniaturize the hardware by approximately 20x, expand operations, and accelerate commercialization. iPronics has opened an office in Santa Clara and partnered with Fabrinet for packaging and assembly. This round underscores the growing importance of optical interconnect in AI infrastructure and highlights European strength in integrated photonics.
Significant funding round for optical switching startup indicates growing investment in AI infrastructure, which is foundational for data-intensive applications like AdTech and MarTech. Nvidia's involvement highlights strategic importance.

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 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.
TSMC Q3 Revenue Up 51% to Record, Stock Falls
TSMC reported a 51% increase in third-quarter revenue to 1.49 trillion Taiwan dollars (EUR 41.7 billion), surpassing expectations. The semiconductor giant, a key supplier to Apple and Nvidia, continues to benefit from the AI boom and strong chip demand. However, the stock declined despite the record results. The company plans to invest EUR 52-56 billion in expanding its manufacturing facilities this year, including a joint venture with Sony for image sensors. TSMC's market capitalization is approximately USD 2.45 trillion, making it the most valuable company outside the US. The company's growth is also boosting Taiwan's economy, with exports rising over 70% in August and GDP expected to grow 11% in 2026.
