Oxagon is becoming a data centre site, and the location supports it

Oxagon, NEOM's industrial district, has been reframed from its original concept — a partly floating octagonal city — into a conventional coastal industrial zone with port facilities. Reporting through 2026 has pointed to a focus on artificial intelligence data centres. Judged on the site's properties, it has an unusually good set of inputs for compute. A data centre needs four things, in roughly this order: power, a cooling path, network, and land that nobody objects to. Oxagon has the first in a form very few sites anywhere can match. The NEOM Green Hydrogen Company development on the same coast — an equal joint venture between NEOM, ACWA Power and Air Products, reported at around 90% complete across all sites in late 2025 — was built with 257 wind turbines and a solar farm on a scale usually described by comparison to city blocks. That generation exists, and it is adjacent. Coastal siting addresses the second. Cooling is the hardest constraint on Gulf data centres, where ambient temperatures make air cooling expensive for most of the year and fresh water is scarce. A coastal site allows seawater-based heat rejection, which is why immersion and liquid cooling have become standard specification decisions across the region's newer builds rather than exotic options. Port facilities address logistics for a build involving thousands of tonnes of equipment. And land at NEOM is not contested. What the site is further from is demand. Data centres are usually built near the users they serve, because latency is a function of distance and most enterprise workloads are latency-sensitive. Oxagon is on the Red Sea coast, some distance from Riyadh, Jeddah and Dammam, where most Saudi enterprise computing happens. For AI training that is not a constraint. Training runs are batch jobs, and a hundred milliseconds of additional round trip is irrelevant when the job takes weeks. For inference serving Saudi users it matters a great deal, which is why HUMAIN's first two facilities are in Riyadh and Dammam. So the sensible division is training at Oxagon, where the power is, and inference near the cities, where the users are. That is roughly the shape the Saudi buildout is taking. The reframing also changes what the site depends on. Its earlier form needed people to move to it, businesses to relocate manufacturing to it, and a novel construction method to work. A data centre campus needs capital, chips and grid connections, and it earns from customers who never visit. Matching a site to the industry its physical properties suit is among the more straightforward decisions in the NEOM programme, and the adjacency of committed renewable generation is what makes it work.
