Meta is building its largest AI training cluster at Hyperion, a data center campus in Louisiana that cost about $27 billion to develop. Meta values its stake in the campus at $2.92 billion. In the same quarterly report, it puts the largest loss it could face on Hyperion at $46.03 billion. That’s nearly 16X the value of its stake.

How Meta Financed Hyperion Without the Debt

Meta has a 20% stake in Hyperion. Funds managed by Blue Owl Capital have the other 80%. Blue Owl raised its share by selling $27.3 billion of bonds that mature in May 2049 to PIMCO and a small group of other investors.

To make that gap acceptable to bond investors, Meta promised to cover shortfalls of up to about $28 billion if it leaves. Meta records that promise at zero.
