Hyliion is not that speculative given how low its market cap remains. x.com 

Hyliion's KARNO generator can win AI data center and defense power demand, while net cash gives the stock a margin of safety. Passing UL certification, the biggest go-to-market hurdle, lets Hyliion start deliveries to early customers. KARNO natively outputs 800V DC, matching AI compute racks and avoiding AC/DC conversion losses; VFG Holdings signed a multi-megawatt data center deal. Navy contracts drove Q1 growth, with $40-50M more military awards expected. Hyliion is debt-free with $139M cash. … Show more

Hyliion's data-center story is weakening because its key VFG Holdings partnership seems to have vanished. VFG, signatory of a nonbinding LOI for up to 50 MW of KARNO units, went unnamed on the Q2 call, and the June 30 10-Q never mentions VFG or the LOIs. The first multi-megawatt data-center delivery is now slated for 2028, and commercialization of the 200 kW KARNO Power Module slipped from end-2026 to 2027. The $41.7 million US Navy contract is the one bright spot. x.com 

IREN has repeatedly misled investors on Horizon 1's timing and economics. Announced in February 2025, it was said in August 2025 to be on track for 2025 delivery and in February 2026 to produce revenue in Q2-26, yet Microsoft only accepted delivery in August 2026. Capex guidance of $6–7M per MW became $14–16M per MW as IREN sells stock through its ATM. CoreWeave added 500MW of revenue-generating capacity in Q2-26 alone, versus IREN's 50MW in 18 months. x.com  x.com 

FuelCell Energy could ride AI data-center power demand with high-temperature fuel cells for clean baseload, scaling 12.5MW FuelCell Blocks for hyperscalers. At about a $650 million market cap, it has $170 million of TTM revenue, Q1 up 61%, a $1.17 billion backlog, $312 million of cash and output ramping to 350MW. Risks are negative gross margins, cash burn, dilution and unproven execution; @SueWallSt notes its 1.5GW of data center deals are proposals and backlog shrank. High risk, high reward. … Show more

Hyliion has pivoted many times, and its latest move is just another attempt to save the business, so investors should be careful. x.com 

Keel Infrastructure trades at a large discount to peers mainly because it lacks a hyperscaler deal, and a single contract could close that gap. It has grid connections in place, a 2.2 GW pipeline and a market cap near $3.8B. Sites are Panther Creek, PA at 350 MW with a path to 500+ MW long term; Sharon, PA at 110 MW; and an 18 MW Moses Lake, WA pilot. CEO Ben Gagnon committed to sign three leases by year-end, and the stock should join the Russell 3000 in June. Leopold added to his position. … Show more

QuantumScape has a second growth leg the market is not pricing: battery-in-rack backup for AI data centers. Its non-combustible ceramic separator lets cells sit inside server racks, buffering millisecond power spikes faster than external UPS systems as racks pass 100 kW. In EVs, Honda signed a development deal after validating hardware. A hyperscaler design win would re-rate it as AI infrastructure. It has $904M of liquidity, but is pre-revenue and depends on scaling its Cobra process reliably. … Show more

Hyliion's KARNO generator has value, but not for data centers. Data centers do not want the maintenance or the logistics of relying on trucks to bring fuel, even if, as a reply argues, the unit can be moved on a flatbed and run on many fuel types. x.com 

AirJoule's first data-center deal is closer than its zero revenue suggests, and the odds of it arriving in the next few weeks or months are very high. Its white paper, written with a leading hyperscale operator and listing $100,000-$200,000 per Prime unit, reads like a pre-sales document; with 18-30 month lead times, revenue could start in late 2026 to 2028. GE Vernova co-developed the tech. The paper models $43-104M per 100 MW campus, 18-43% of the $240M market cap. No contract is signed yet. … Show more
