Navitas remains a wait-and-see name because its high-voltage products are years from real revenue. The US Army selected it for ALATTIS, a program to build domestic 10 kV silicon carbide power devices, which validates its engineering and fits its roadmap toward solid-state transformers for AI data centers alongside its Nvidia 800 V work. But it is a prototype program with no disclosed value, and 10 kV devices are years from volume revenue. x.com 

Navitas is a one-customer concentration story facing heavy competition from tier-one suppliers. Its GaN portfolio winning Nvidia adoption played out, but STMicroelectronics and Infineon also supply Nvidia and are strong in GaN and SiC. GaN output may quadruple by 2030, yet SiC prices were hammered by Chinese capacity, unresolved, so revenue and margins could diverge sharply. Power and thermal efficiency are better played across these names than through Navitas alone. x.com 

Navitas is an option on Nvidia's 800V DC data-center architecture, where GaN handles the step-down from 800 volts to processor level inside the rack. The design halves power conversion stages so racks can reach the up to 8 megawatts Rubin Ultra needs, with full deployment alongside Kyber in 2027. Navitas, on Nvidia's partner list, is the only US-listed pure-play GaN company. Revenue is minimal until the Kyber ramp, and Nvidia's 29-company partner list means hard pricing pressure. x.com 

Navitas is exposed to a real thesis, power delivery as AI's next bottleneck, through a high-risk stock. Rack power is heading from 150kW to over 1,000kW, and Navitas has full-stack GaN and SiC, an 800V HVDC design partnership with Nvidia and a 96.5%-efficient 800V-to-6V board. But Q4 2025 revenue fell 59% to $7.3M, it trades near 211x trailing EV/revenue, loses money, revenue inflection is 2-3 years away, and Infineon, Vicor and Delta got similar Nvidia mentions. Valuation conviction is low. … Show more

Alphabet and Broadcom should benefit because bipolar 400V power, not 800V HVDC, is the faster on-ramp for AI data centers, especially custom ASIC clusters. Nvidia's Rubin still favors 50V DC at the tray and solid-state transformers lack medium-voltage support, so 800V today means inefficient step-down, step-up, step-down conversions; the direct path is 2+ years away. Hyperscalers already have mature ±400V designs via OCP, amplifying Google's TPU efficiency edge and Broadcom's ASIC momentum. … Show more

Navitas offers exposure to Nvidia's push to 800V DC data-center power through its high exposure to SiC and GaN ICs for 800V DC. Nvidia has begun talks with major South Korean power equipment makers on DC infrastructure built around an approximately 800V system, a big signal that Nvidia is really driving the shift. Navitas is among Nvidia's previously named partners, alongside Infineon, Texas Instruments, Eaton and Vertiv. x.com 

Power Integrations should be very successful over the next one to five years because it makes the only GaN switches needed for NVIDIA's new rack architecture. x.com  x.com 

Power Integrations addresses the coming AI data-center power bottleneck, where the real alpha lies. Next-generation AI data centers are shifting to 800 VDC, and traditional silicon cannot handle the power density and heat of megawatt-scale racks. Power Integrations is working with Nvidia on that transition, and its 1250V and 1700V PowiGaN switches exceed 98% efficiency while cutting copper and board space. Despite the run, its repricing is in early innings as data-center revenue scales. x.com 

Denser AI accelerators raise the value of efficient power delivery near processors, potentially making Navitas one of the most hidden AI winners in Nvidia's architecture. Its 24 kW board targets single-stage 800V-to-12V conversion at about 97% efficiency in Nvidia's 400 mm by 60 mm format. An 800V-to-6V design developed with Nvidia and Claros offer other paths into the power stack. This is a showcase, not a production order; shipment volumes, revenue and competition remain uncertain. x.com 

Navitas Semiconductor's Nvidia deal is worth far less than the hype suggests: even with the 40% share people expect, it might add only about $30M in total revenue. Wolfspeed already has almost double that in annualized data-center revenue today, before any 800V data centers or power-grid upgrades. x.com
