Boost Run signs $525.6M GPU cloud deal with Cohere

WIRE · NEOCLOUDS · US · Data as at 6 Oct 2026

Boost Run, a Nasdaq-listed GPU cloud, has signed a five-year deal with AI model maker Cohere worth about $525.6 million. Cohere will rent dedicated racks of Nvidia GB300 NVL72 systems. On the neoclouds layer, that is a signed renter, which is the hard part. But the contract only bills a rack once Cohere accepts it, and the first racks are not due until the second quarter of 2027.

What happened

On 6 October 2026, Boost Run announced a five-year AI cloud deal with "a leading sovereign AI company." Its 8-K filing the same day names the customer as Cohere. The agreement was signed on 30 September 2026.

The facts as filed:

The prepayment amount, the number of racks and the minimum that must be accepted are blacked out in the public filing.

Why cash cares

A neocloud earns money when a customer pays for GPU time. A signed contract is a promise of that money. It is not the money.

This contract spells out exactly when the money moves. Anything due at signing is paid at signing. The rest of the prepayment comes in rack by rack, in step with the GPUs in each rack as it is accepted. Monthly fees for a rack cannot even be invoiced until Cohere accepts it. Once a rack is accepted, Cohere pays for the full term whether it uses the rack or not. That last part is what lenders like. It works like a take-or-pay contract.

So the whole deal turns on one word: acceptance. Boost Run has to build each rack to Nvidia's reference design and send Cohere a test report. Cohere then has seven business days to check it. If a rack fails, Boost Run gets 20 business days to fix it, and one more try after that.

To size it, here is our own arithmetic, not a disclosed figure. If the $525.6 million were spread evenly over five years, that is about $105 million a year, or close to $9 million a month, once every rack is live. It is roughly a fifth of the $2.6 billion Boost Run says it has signed in total. The real schedule is not public.

Figure — Acceptance bind. Signed on 30 Sep → racks pass tests and are accepted by 15 July 2027 (stuck step) → monthly fees bill for each accepted rack.

The date that does not move

The contract has one fixed date. 15 July 2027 is the last day for racks to be accepted. The filing says that date holds no matter what, even through events outside anyone's control.

If the minimum amount of racks is not accepted by then, Cohere can walk away and get back everything it prepaid. If the minimum is met but some racks are late, Cohere can drop just those racks and get their share of the prepayment back. Boost Run's parent company guarantees those refunds.

Here is the catch. If Nvidia or a server maker is slow to ship parts, the 20-day repair windows stretch to match. The 15 July 2027 deadline does not. Supply risk sits with Boost Run, not with Cohere.

The second-order read

Who gets paid. Nvidia and the server makers, first, when Boost Run buys or leases the racks. Then the data center hosts. The contract also lets Boost Run hand its fee stream to a lender, so lenders are paid from Cohere's monthly bills.

Who pays. Cohere, in steps. Some at signing, more as racks are accepted, then monthly for about five years per rack.

Who waits. Boost Run. It has to spend on hardware and space in 2027 before the monthly fees start. Until the deadline passes, its prepaid cash can still be clawed back.

Stuck step. Getting racks built, tested and accepted by 15 July 2027. Until a rack is accepted, it bills nothing.

Two cautions

The $525.6 million depends on delivery and acceptance, and Cohere has some other exit rights the filing does not detail. Read it as the most the deal pays, not money banked.

The yearly and monthly figures are our even split. The real fees may ramp as racks come online, so early months will likely bill less.

What would change the view

• Boost Run says how much of the prepayment it has already received.
• It names where the racks will sit and when the first group is ready for testing.
• It shows how it is paying for the GB300 racks: cash, debt against the Cohere fees, or a lease.
• Any delay notice before July 2027, which the contract requires it to send.

What to watch

• The first acceptance notice, expected in the second quarter of 2027.
• Boost Run's next quarterly report, for prepayments and spending on equipment.
• GB300 supply from Nvidia and the server makers through mid-2027.
• Any new financing secured against the Cohere fee stream.
