Ideal Power's B-TRAN switch fits the solid-state breakers required in Nvidia's 800V DC racks, an overlooked chokepoint. At 800V DC, mechanical breakers are too slow to stop fault arcs; B-TRAN is one two-way switch instead of two, wasting about a quarter of the energy. A May 14 LOI covers a prototype for a US hyperscaler, due end-2026, with a possible 2027 ramp. With $0 revenue, it is a lottery ticket on that turning into repeat orders, with $16M+ cash and no debt cushioning the downside. x.com 

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 

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 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 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 

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 

Meta's unmet AI demand pays its bottleneck suppliers. Super Micro's $19.5B quarterly outlook and under 8x forward earnings point to a double. CoreWeave's Meta deals total $35.2B; it should easily top $100. Builders say nearly all new sites use Dell or Super Micro; Dell could easily double. Micron's demand is off the charts at 5x forward earnings. Sources say Vertiv's gear is sold out for 2-3 years. VivoPower has 2GW+ potential in 5-7 years. Digi Power X has a $1.1B Cerebras deal. x.com  x.com  … Show more

Powell Industries is a quality grid business priced too richly at 57x trailing earnings after a 175% gain this year. Its custom medium-voltage switchgear for data centers comes from few qualified vendors; orders nearly doubled to $490M, backlog is $1.8B, it won a record $400M+ data center contract, and gross margins rose from 16% to nearly 30%. But the valuation needs it to become a capacity-constrained AI power platform, and if AI capex slows in 2027, the multiple compresses first. 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 

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
