↑ 1%The AI investment landscape is entering a second phase focused on infrastructure testing and validation, away from the chip-focused first phase dominated by Nvidia. This shift is creating opportunities in less visible sectors. Keysight Technologies reported record fiscal Q1 2026 results with revenue of $1.6 billion, up 23% year-over-year, and orders of $1.65 billion. For the first time, wireline revenue exceeded wireless revenue, driven by demand for 800G and 1.6T optical transceiver validation needed for AI data centres. The company's software and services now represent 40% of revenue, with recurring revenue at 29%. Management projects full-year fiscal 2026 revenue growth above 20%. Despite an 80% gain over 52 weeks and a 23% post-earnings surge, the stock trades roughly 10% below analyst consensus targets at approximately $290 per share.
Calix has announced that regional service providers Blue Stream Fiber, XMission and Aervivo are expanding use of its Calix One platform and SmartMDU managed Wi-Fi across multi-dwelling unit properties in multiple US states. The expansion includes new Wi-Fi 7 hardware and QR code self-activation. The company projects $1.3 billion revenue and $195.4 million earnings by 2028, requiring 13.4% yearly revenue growth. Approximately one-third of customers are already on the unified platform, with full transition expected by March 2026. The SmartMDU expansion supports Calix's shift from broadband hardware sales to a software and services platform. However, the key risk remains whether customers will adopt AI-driven workflows and pay higher per-subscriber fees, with cautious analysts projecting more modest growth through 2029.
Calix has launched Calix One, an AI-native platform designed to enable personalised experiences for service providers, marking a strategic shift towards software-led customer experience over hardware sales. The company is positioning itself to capture higher recurring revenue through AI-driven software and subscriber experience tools. The company has partnered with Google Cloud to support private-cloud deployments, addressing sovereign and enterprise requirements. This expansion removes adoption barriers for larger operators and government-sensitive deployments whilst broadening Calix's addressable market. Management expects Tier 1 opportunities to begin contributing in late 2026, with material impact in 2027. These software-only deals could drive margin expansion, though sales cycles run 18 to 24 months. Investors will watch for customer uptake evidence and competitive response to validate the platform shift.
Calix has raised $120 million in Series C funding at a $1.45 billion valuation, led by Ribbit Capital with participation from Sequoia, Kleiner Perkins and new backer Emerson Collective. The pre-revenue AI startup, co-founded by Robinhood CEO Vlad Tenev, has now raised $295 million across three rounds in 14 months. The company is developing "Mathematical Superintelligence", eliminating AI hallucinations by requiring outputs in verifiable Lean4 programming code. Its Aristotle model achieved top performance at the International Mathematical Olympiad in July alongside Google and OpenAI. Harmonic currently offers Aristotle via free API to mathematicians and researchers, with plans to commercialise in safety-critical sectors including aerospace, automotive and finance where reliability is paramount.
Calix has announced that Blue Stream Fiber, XMission and Aervivo are using its SmartMDU platform to expand into the multi-dwelling unit market, which accounts for over one-third of US housing. The service providers are deploying managed Wi-Fi across affordable, luxury and mixed-use properties. SmartMDU, launched in October 2024, recently added Wi-Fi 7 systems and resident self-serve activation via in-unit QR codes, enabling immediate connection at move-in. The platform integrates with Calix One to deliver scalable, secure connectivity. Blue Stream Fiber, an early adopter, plans to add over 15 properties in 2026 and has achieved a 4.9 out of 5 satisfaction rating. Service providers report near-perfect satisfaction scores and faster time to revenue using the standardised deployment model.
