iPronics Raises $125M for Optical AI Networking Switches
Spanish startup iPronics, a spin-off of the Technical University of Valencia, has raised a $125 million Series B round led by Maverick Silicon and Light Street Capital, with participation from Nvidia and other investors. The company develops optical circuit switches (OCS) that route data in AI data centers entirely via light, reducing latency and power consumption. Its first product, the ONE-32, offers 32 ports with sub-30 nanosecond latency and reconfiguration under 300 microseconds. The funds will be used to shrink hardware by roughly 20x, expand commercial operations, and scale production. iPronics has shipped its product for about a year to undisclosed Tier-One AI infrastructure partners and opened a Silicon Valley office. The investment reflects a broader shift toward optical interconnects as AI clusters hit network and power limits. Total funding raised now stands at $177 million.
Major Series B funding for an optical switching startup with Nvidia participation signals a growing shift towards optical interconnects in AI data centers, underpinning the compute infrastructure that digital advertising and AdTech ecosystems depend on.

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.
Samsung posts record profit, announces record dividend
Samsung reported an operating profit of €71.68 billion for Q3 2026, a nine-fold increase year-over-year, marking its fourth consecutive record quarter. Revenue rose 127% to €130 billion, slightly below market expectations. The surge is driven by soaring memory chip prices due to a global data center construction boom, particularly for AI high-bandwidth memory (HBM). Samsung plans to invest in additional production capacity and seeks long-term supply contracts to mitigate pricing volatility. Despite the strong results, Samsung's stock fell 2.4% in Seoul, while Hynix and Micron also declined. The company's smartphone division suffered an unexpected loss of €894 million due to rising component costs. Samsung will also distribute a record €73 billion to shareholders this year.
Microsoft Unveils Hybrid Intelligence, Open-Weight AI, RTX Hardware
Microsoft is repositioning Windows as a platform for 'hybrid intelligence,' enabling AI agents to run locally on PCs or in the cloud. The company announced the general availability of Microsoft Execution Containers (MXC), which sandbox agent execution and control access to files and networks, with support from Codex, GitHub Copilot, OpenClaw, and others. New AI models, including Microsoft's MAI Code 1.1 Flash, Nvidia's Nemotron, and DeepSeek V4 Flash, will run locally on RTX Spark devices, including the Surface Laptop Ultra (available for pre-order at $2,599). Copilot is gaining access to local files and system actions on Copilot+ PCs, rolling out in the coming months. Microsoft is diversifying its AI partnerships beyond OpenAI, building its own models, and aiming to regain trust after past missteps by emphasizing security and on-device processing.
