Divide the expected $5bn by the 250 megawatts it is supposed to come from [4][3] and the site is being penciled at $20m of gross revenue per megawatt per year [1], which is about $2,283 for every megawatt-hour if the halls somehow ran flat out through all 8,760 hours of the year [2], and that figure only holds if nearly every hour sells at frontier GPU pricing and HUMAIN delivers power and shells on time. Held another way, one 250MW building's first-year gross revenue would equal roughly 2.5% of the entire Saudi digital economy as the kingdom's own ministry measures it [9][7]. "Expected" is carrying most of the weight in that sentence [4].
The more useful comparison sits inside the same day's announcements. AWS's ceiling is one fifth of the capacity Together AI put its name to [3] and one tenth of what xAI says it will eventually reach [4], and it is the only one of the three that arrives with a delivery year attached, 2028 [5]. The best-capitalized participant took the smallest allocation on the longest runway, which is what an option looks like sitting next to a position, and it is the cleanest available check on how firm the bigger numbers are.
Which makes $15bn of planned investments and strategic commitments the least informative figure in the file [1]. What can be marked later is 800MW at full build [5], 350MW across the first phases [6], and that single date. Set against a digital economy that has added $81bn since 2022 [7][7], $15bn of fresh commitments is about 19% of the increase [8], though the announcements are a flow and the economy a measured stock, so read the ratio as scale rather than as evidence.
Then there is the ground the racks sit on. The conference itself ran four months late because of the Iran war [2]; up the coast, Dubai's airport infrastructure has taken 16 missile strikes since February [9], its half-year passenger count fell 31.3% to 31.5 million [10], and Europe's aviation regulator has told airlines to stay out of Gulf territorial airspace until 30 September [11]. Riyadh's main rival for the regional hub role is the UAE [8], and the reading splits three ways: capital rotating toward Riyadh on relative safety, both capitals pricing the same missile envelope and building anyway because compute demand will not wait for a ceasefire, or foreign operators taking Gulf land and Gulf power while keeping their own capital light and their exposure purely contractual.
This is probably wrong on timing, but the durable structure being assembled at LEAP is HUMAIN sitting on both sides of foreign compute, as landlord and as counterparty [5][3], which is a more permanent position than writing equity checks into other people's labs. The counter-thesis is dull and often right: announced megawatts convert at a discount in every jurisdiction, and a site whose economics require $20m per megawatt [1] is precisely the sort that gets rephased quietly. Two things would move me off it, and both are observable: AWS lifting its 50MW figure before 2028 [5], or Together AI disclosing signed offtake anywhere near $5bn [4].
