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.comÂ
Navitas's pivot from low-margin phone chargers to high-power AI data-center chips is now showing in its numbers. Q1 revenue of $8.6M beat its $8.0-8.5M guidance, high-power markets grew 35% year on year to become most of the business, and margins expanded on the better mix. Q2 guidance of $10M implies 16% sequential growth, and Q2 needs to confirm the turn. x.comÂ
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.comÂ
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.comÂ
Navitas's place in NVIDIA's 800 VDC ecosystem carries little pricing power because the silicon tier is crowded. NVIDIA names fourteen silicon suppliers, Navitas among them, and rent comes from scarcity; SiC and GaN also split the socket by stage. Per SemiAnalysis, rollout is phased, and the first stage is a retrofit into existing wiring with the smallest content per site. Unlike optical, no 800 VDC tier has disclosed dollars yet; a first order with a figure and date would change the picture. … Show more
Navitas' AI power case got another green light: Nvidia's Jensen Huang says the 800 VDC power rack roadmap remains intact, with shipments in the second half of 2026. Navitas' GaN and SiC chips sit directly in the rack's power-conversion path, and its 5th-generation GeneSiC technology supports a pivot from low-margin consumer electronics toward AI data centers, grid and industrial customers. QuantumScape's solid-state batteries are positioned for high-density backup units in these racks. x.comÂ
Navitas Semiconductor's opportunity now spans the entire AI power stack, from the grid to the chip, not just GaN. As StockSavvyShay noted, closing Claros adds integrated voltage regulators next to AI processors and more than doubles Navitas's 2030 AI power opportunity to $8B, covering 10 kV SiC near the grid, 800V rack conversion, GaN in the rack and power at the chip. x.comÂ
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.comÂ
Navitas is the highest-beta standalone pure play on gallium nitride for the shift to 800V DC data centers. It pivoted from consumer GaN chargers, where it was losing share to cheap Chinese rivals, to higher-margin AI data-center solid-state transformers, where it is seen as the default GaN supplier, even ahead of Infineon. An acquisition two years ago added credible silicon carbide capability. Execution risk is high for a small company making such a concentrated bet. x.comÂ
Nvidia's official 800 VDC architecture partners stand to benefit as AI racks move to high-voltage DC power. They span GaN and SiC chipmakers Navitas, STMicroelectronics, onsemi and Infineon; conversion and analog suppliers Alpha & Omega, Power Integrations, Texas Instruments, Analog Devices and Monolithic Power, whose VRM chips are already inside Nvidia GPUs; and rack, building and grid power players Flex, Vertiv, GE Vernova, ABB, Eaton, Schneider Electric and Siemens. x.comÂ
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
A rising value of compute per watt should benefit AI cloud, chip, connectivity and power suppliers. Elon Musk says that value will rise over time. Nebius has Microsoft and Meta deals; Marvell benefits from custom silicon demand; Credo connects GPUs; Vistra has long-term nuclear supply deals with Amazon and Meta; Nokia's Nvidia partnership could help it capture data-center networking growth. x.com x.comÂ
