LG lands on the five-product list of Nvidia-certified 2.5-megawatt coolant units

An approval is an option on orders, and the people nearest the deal say as much. "Actual orders depend on Nvidia's decision, but technically the five products approved at the 2.5-MW class are in a favorable position," an industry official told Seoul Economic Daily ^[4]. LG did not disclose an order, a price, or a revenue target for the unit.

One product in six on the DSX Ready list is rated at 2.5 megawatts ^[1]. That rung is narrow because Nvidia's sizing makes it narrow. Divide 2,500 kilowatts by the roughly 120 kilowatts a rack draws and you get 20.8 racks per unit. A full 20-rack row leaves 100 kilowatts of spare cooling, less than one more rack ^[2]. A buyer who adds a twenty-first rack buys a second CDU. Split evenly, Nvidia's 2.5-megawatt cooling spend would hand LG a fifth of it ^[6].

The program is newer than the qualifications inside it. Cryptobriefing dates the DSX Ready launch to September 21, 2026 ^[8], and LG's 600-kilowatt unit qualified on July 27, 2026, 56 days before that ^[5]. By the time Nvidia put a name on the standard, more than 30 coolant units had already passed it ^[5].

The demand case rests on a forecast. TrendForce expects liquid cooling adoption in AI data centers to reach 60% next year from 14% in 2024 ^[11], a 4.3-fold rise in penetration ^[3]. Cryptobriefing puts the AI data center cooling market at roughly $133.5 billion by 2034, growing about 26% a year ^[13]. Compound 26% across the nine years from 2025 and the market multiplies about eightfold, which implies a base near $17 billion today ^[4]. "With this approval under Nvidia's DSX standard, we will begin supplying more reliable and efficient cooling solutions to global big tech companies in earnest," said Lee Jae-sung, head of LG Electronics' ES Business Division ^[14].

It can go otherwise. Nvidia could certify another five units at 2.5 megawatts, and each one dilutes LG's place on the list. Rack density could keep climbing until the standard row resizes, in which case the 1-megawatt and 600-kilowatt approvals LG already holds matter more than the new one ^[7]. Or coolant distribution units commodify against a published Nvidia specification, and LG wins slots at assembly margins.

In my view the certification is worth more as a design-in position than as 2026 revenue. What LG cleared (temperature held within plus or minus 0.25 degrees Celsius, with virtual sensors, leak detection and failover ^[10]) is the sort of thing a buyer keeps once it is qualified, and requalifying a cooling loop delays the build. The thesis fails if a sixth, seventh and eighth product clear the 2.5-megawatt bar before Nvidia places its first orders.
