CoreWeave Stock and CRWV AI Capex: What a Neocloud Data Center Really Costs

November 5, 2026 7 min read Strategic Crypto Reserve AI Markets

CoreWeave (CRWV) plans to spend $35 to $39 billion of capital in 2026 to build GPU cloud capacity, and its stock has become the market's gauge of the AI build-out. After falling about 10% in the November 5 sell-off, CRWV was down roughly 76% from its June 2025 peak. Here is where the money goes, what a neocloud data center costs per megawatt, and what to watch at Q3 earnings on November 10.

Quick answers (updated November 5, 2026)

How much is CoreWeave spending? CoreWeave guided 2026 capital expenditure to $35 to $39 billion, up from earlier ranges of $30 to $35 billion and then $31 to $35 billion. Q3 2026 capex was guided at $11.5 to $13.5 billion.

How much capacity? about 1.5 GW of active power at Q2 2026 (nearly 500 MW added in the quarter) and 4.2 GW contracted.

Who pays? on recently signed deals, customer upfront payments cover about 50% to 60% of the capex; the rest is largely debt.

Stock: CRWV fell about 10% on November 5, 2026 and was about 76% below its June 2025 peak, CNN reported.

Build cost: our configurator's neocloud profile puts the building, power and cooling at about C$20.5 million per MW before GPUs; the GPUs cost several times more.

CoreWeave Capex: $35 to $39 Billion in 2026

CoreWeave is a neocloud: it buys NVIDIA GPUs, installs them in data centers it leases or builds, and sells GPU time to AI labs and hyperscalers. That model is capital-hungry, and the guidance shows it.

Q3 2026 capex guidance$11.5-13.5 billion
Active power (Q2 2026)~1.5 GW, nearly 500 MW added in the quarter
Contracted power3.7 GW at Q2, 4.2 GW since
Revenue backlog (Q2 2026)about $104 billion
Customer prepayments on new deals~50-60% of capex

CoreWeave has said it aims to add about 5 GW more capacity by 2030. Every one of those megawatts needs a building, a substation and cooling before the first GPU is switched on.

CoreWeave Data Center Cost: What a Neocloud Hall Costs per MW

CoreWeave does not publish a cost per megawatt, and dividing capex by new megawatts mixes GPUs with buildings. A cleaner way is to split the two. Our AI Build Configurator has a Neocloud / GPU-as-a-Service profile with these default inputs (US national baseline, Canadian dollars):

Neocloud data center build cost before accelerators (C$ million per MW of IT load)
Line itemC$M per MW
Shell and core10.50
Electrical and mechanical fit-out4.90
Land0.12
Utility interconnection0.40
Network0.87
Direct-to-chip liquid cooling3.68
Total facility before GPUs~20.5

On top of that sit the accelerators, which are usually the largest single cost in a neocloud build because the operator owns the silicon. Density matters too: the profile assumes about 130 kW per rack, which only liquid cooling supports. The free demo adds GPUs by class (NVIDIA or AMD), applies the local construction factor and sales tax, and shows payback at a blended price per GPU-hour. For state-by-state facility costs see data center cost per MW by state.

Neocloud data center cost per MW: about C$20.5 million before GPUs

CRWV Stock: The Sell-Off and What to Watch on November 10

On November 5, 2026, a tech rout wiped about $2.5 trillion off US stocks after the midterm results raised fears of slower data center construction, including a proposed temporary data center moratorium in Texas. CoreWeave fell about 10%; CNN put it about 76% below its June 2025 peak.

CoreWeave reports Q3 2026 results on Tuesday, November 10, 2026, with a call at 5 p.m. Eastern. Things to watch:

  • Capex versus revenue: whether the $35-39 billion range holds, and how fast new capacity turns into billed GPU hours.
  • Power online: megawatts actually energised versus contracted. Delays move revenue out.
  • Funding: the share of capex covered by customer prepayments versus new debt.
  • Customer concentration: how much backlog comes from a few large AI labs.
