Navitas Semiconductor Stock Soars 346% YTD as it Partners with NVIDIA on AI Infrastructure

Navitas Semiconductor's stock increased by 346% in 2026, making it more valuable than SpaceX at a certain point. The surge in value is linked to the company's partnership with NVIDIA on AI infrastructure. This partnership has positioned Navitas to benefit from growing demand for AI infrastructure buildouts, and its stock surged further after NVIDIA featured its 800V-to-6V DC-DC power delivery board at the Computex 2026 conference.

Navitas Semiconductor (NVTS) has been one of 2026's standout small-cap rallies, up several hundred percent year to date, as it deepens its collaboration with NVIDIA (NVDA) on next-generation AI data-center power . At COMPUTEX 2026 in Taipei, Navitas showcased an 800 V-to-6 V GaNFast power-delivery board built for NVIDIA's MGX AI-factory ecosystem, targeting 97.5% efficiency, 1 MHz operation, and 2,100 W/in3 power density .

The design supports the industry's shift to 800 VDC rack architectures, which eliminate the traditional 48 V intermediate bus-converter stage inside compute trays and help data centers handle the soaring power demands of AI accelerators . Navitas also participated in NVIDIA's partner ceremony on May 29, underscoring its role in the MGX supply chain.

The collaboration positions the chipmaker, whose market value sits in the single-digit billions, as a leveraged play on AI-infrastructure power delivery. That upside comes with volatility: the stock has seen sharp two-way swings around the announcement, and its valuation now embeds high expectations for design wins to convert into sustained revenue.
