Musashi Seimitsu is turning from a struggling, 90-year-old auto parts maker into a key AI data center supplier, which nobody is pricing in. It is one of few hybrid supercapacitor makers, pairing battery-like energy density with capacitor-like response. As AI moves to 800V power, only supercapacitors react fast enough to GPU load spikes, likely making them standard in every rack. Partner Flex is launching a storage system on its cells, and output is scaling from 200,000 to 6.5 million cells. … Show more

Handling giant voltage and power swings is a big and arguably underappreciated opportunity over the next two to three years for battery storage and supercapacitor makers. Musashi Seimitsu and VinaTech are the preferred ways to play supercapacitor demand. x.com  x.com 

Musashi Seimitsu is the only maker mass-producing hybrid supercapacitors for AI data centers, and that supply gap could become a structural constraint like CoWoS in 2023. Nvidia built them into power delivery from GB300, about 300 per NVL72 rack, implying demand on the order of ten million units in 2026 versus Musashi capacity of 6.5 million by Q3 2026; Ming-Chi Kuo notes the count may be cut. Rubin should use more, Skeleton and Jianghai trail, and the 800V HVDC shift needs requalification. … Show more

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

Musashi Seimitsu is a higher-torque play on the AI power and 800V theme than MLCC makers like Murata and Taiyo Yuden. Its supercapacitors smooth AI workload power spikes, a role that grows as architectures move to 800V; Skeleton's product suits peak shaving and is more complementary than competitive. The supercapacitor market could top $15B within years at likely 20%-30% operating margins versus 5% in the base business, which could lift operating profit over 10x. Target: a 2x in 12 months. x.com  … Show more

Panasonic's rack-level backup architecture addresses the AI buildout's biggest near-term constraints, grid interconnection queues and power quality at 100kW-plus densities, an asymmetric play on power as AI's bottleneck. Hyperscalers can add protected kWh per rack instead of overbuilding central UPS, and peak shaving flattens spiky loads. Supercapacitor CBUs, targeted for FY27, handle fast transients for the 800VDC shift. Over 80% of FY29 is locked in design wins. x.com 

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.com 

Inference's move toward edge devices and dense, memory-hungry racks should drive demand for specialized chips, links, power delivery and cooling. McKinsey projects inference at 60% of AI computing demand by 2030. Ambarella makes on-device AI chips; Astera Labs links GPUs, memory and networks; Credo supplies short copper connections; Rambus earns from memory interfaces; Navitas reduces power waste; Modine cools dense racks; and Super Micro builds inference-specific server racks at volume. x.com  … Show more

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 

AI's biggest bottleneck is power and cooling, not memory, making Vertiv, GE Vernova, Bloom Energy and Eaton buys. Musk expects a prolonged compute shortage; Nvidia, Broadcom, Micron, SK hynix, TSMC, Arista, AMD, Marvell, Credo, Lumentum, ASML and Astera Labs could benefit massively. Grok Bot's 800,000 paid weekly users have more than doubled in a month; Musk says agents could eventually use more compute than any other part of SpaceX's Super Intelligence business, benefiting Dell and Sandisk too. … Show more
