Ideal Power fits SemiAnalysis's 800VDC data center thesis: its patented B-TRAN bidirectional switch powers solid-state circuit breakers, the protection technology SemiAnalysis calls critical because DC arcs do not self-extinguish. With its Q1 2026 results, it reported signing an LOI to co-develop a B-TRAN-enabled breaker prototype for a US hyperscaler. At a $135m market cap, the upside is asymmetric if the company executes. x.com 

Ideal Power's gap between almost no revenue and a ~$100M valuation is the opportunity, if it turns a test project into repeat orders. Its bidirectional switch replaces two one-way parts and wastes about a quarter of the energy in always-on jobs like breakers, which AI data centers and grids moving to 800V need by the millions. Its pipeline rose from $200M to $300M in a quarter, a big breaker maker signed a multiyear deal, and a hyperscaler will test it in Nvidia's 800V racks. No orders yet. … Show more

Ideal Power's 800V data-center case gains a named commercial partner in Lazzen, which is building B-TRAN-enabled products for AI data centers. Per @TheBullWhisper's find, the 1-2% figure in investor materials captures only conduction losses, so the system-level impact may be larger once cooling and rack density are counted. @TheBullWhisper adds that its value could be far bigger if it wins hyperscaler designs. x.com 

Ideal Power has de-risked somewhat, though a delay in Stellantis automotive certification argues for waiting weeks or months. It signed a long-term supply agreement with a high-volume Asian wafer foundry where functional B-TRAN first silicon is already made, at a cost it says supports gross margins at scale. It also got a first stocking order for its 800V solid-state circuit breaker kit, a first revenue signal, and holds $41.3M of cash with no debt and about four years of runway. x.com  x.com  … Show more

Ideal Power could re-rate sharply because its solid-state bidirectional switches let power flow both ways between the grid and facility-level energy storage, and it is the highest-conviction name of its size. The switches are at the same stage as Wolfspeed's without competing with them, and the latest earnings report was good. @hiteshkar adds that if qualified, it would be the most unique product on the market, ideal for behind-the-meter protection. x.com  x.com 

HVDC and 800V DC power delivery is the theme to focus on now, with STMicroelectronics, Navitas, Hyliion and Ideal Power as the preferred bets. Across the AI buildout, power and optics keep gaining narrative strength and attention, while packaging remains critical but is increasingly well understood by the market. x.com  x.com 

Enphase Energy should return to the $70s or higher soon on its solid-state transformer for AI data centers. Enphase says power modules for its IQ Solid-State Transformer are being built in Texas to assemble and validate full-scale racks that convert medium-voltage AC directly to 800 VDC, reducing the need for battery buffering near AI compute racks. The announcement is not new to anyone following the earnings calls, which explains the earlier run-up. 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 

Vertiv should be a net winner in power content per megawatt as AI racks move to 800V DC. The shift will cannibalize its legacy UPS and AC distribution, but it is building the replacements: centralized rectifiers, 800V busway, DC energy storage and rack-level DC/DC, while cooling remains a big opportunity either way. Nvidia targets 800V DC for MW-scale racks from 2027, though only 15-25% of data centers may adopt it by 2030, mostly as hybrids on an AC backbone, so AC isn't going away. x.com 

Power Integrations' GaN technology is locked into Nvidia's next-gen AI supply chain through its auxiliary power-supply designs for Nvidia's Kyber 800V DC liquid-cooled racks, where its high-voltage GaN chips deliver high efficiency in a tiny footprint. Its 1250V and 1700V devices from the Odyssey deal are gaining traction in industrial drives, 800V EVs and solar inverters. With its consumer business recovering from a cyclical bottom, earnings recovery plus an AI re-rating set up a double play. … Show more
