Is CORZ a Buy? What to Consider in 2026
Short answer
The bull case for CORZ (CORZ) rests on CoreWeave hosting contract and AI colocation: The roughly 590 MW, 12-year CoreWeave agreement gives Core Scientific a large, contracted AI-hosting backlog with multibillion-dollar revenue potential over its term. Revenue (recent quarter) is ~$115M. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: CORZ carries substantial execution and concentration risk: a very large share of contracted future revenue depends on a single customer, CoreWeave, whose own demand and financial health drive the thesis. Whether CORZ is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Core Scientific runs large-scale data centers across the US that were originally built to mine bitcoin. Over 2025 and 2026 the company has pivoted hard toward hosting AI and HPC workloads, dismantling or repurposing mining rigs and selling down its bitcoin treasury to fund the build-out. Its centerpiece is a roughly 590 MW, 12-year colocation agreement with AI cloud provider CoreWeave carrying multibillion-dollar revenue potential, alongside a broader multi-gigawatt power pipeline the company is developing for high-density compute. The investment picture is a bet on that transition rather than on today's earnings. Colocation revenue is growing quickly at healthy gross margins, and contracted future revenue and lease commitments are large, but reported results still show heavy net losses driven by impairments on retired mining gear and the cost of the pivot. A notable twist: CoreWeave agreed to acquire the whole company in mid-2025, then that merger was terminated in October 2025 after shareholders rejected it, leaving CORZ independent but still bound to CoreWeave as its largest hosting customer.
What's the case for buying CORZ?
1. CoreWeave hosting contract and AI colocation
The roughly 590 MW, 12-year CoreWeave agreement gives Core Scientific a large, contracted AI-hosting backlog with multibillion-dollar revenue potential over its term. Colocation revenue has climbed sharply (around $77.5M in the most recent quarter at roughly 57% gross margin), and management is targeting full CoreWeave delivery by early 2027. This anchored demand is the core of the equity story.
2. Power pipeline and capacity expansion
The company is developing a multi-gigawatt power pipeline (management has referenced roughly 4.5 GW) to convert into high-density AI and HPC capacity. Securing, energizing, and leasing that power at attractive per-megawatt rates is what would scale revenue well beyond the current run rate. Execution speed and cost of build-out are the swing factors.
3. Shift away from bitcoin mining economics
Core Scientific is winding down self-mining and reallocating power to AI hosting, where margins have been meaningfully higher than mining. It has been selling its bitcoin holdings to help fund the pivot. This reduces direct exposure to bitcoin price and network difficulty, trading crypto volatility for data-center customer-concentration and construction risk.
4. Balance sheet and financing capacity
The company raised roughly $3.3B via 7.75% senior secured notes due 2031 and reported liquidity near $1.04B, giving it capital to fund the AI build-out. Ample financing supports growth but adds interest cost and leverage, so the return depends on the new capacity generating cash faster than the debt compounds.
What are the risks to CORZ?
CORZ carries substantial execution and concentration risk: a very large share of contracted future revenue depends on a single customer, CoreWeave, whose own demand and financial health drive the thesis. The company is still reporting large net losses (a recent quarter showed a net loss near $347M, including a roughly $266.5M impairment on mining assets), so profitability depends on the AI ramp arriving on schedule. Construction delays, power-availability constraints, rising interest costs on its 2031 notes, and any slowdown in AI/HPC demand could each materially hurt results. The stock is highly volatile, and residual bitcoin exposure plus the aftermath of the terminated CoreWeave merger add further uncertainty.
How is CORZ valued? (as of JULY 2026)
Snapshot for CORZ as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Market cap: ~$7.5B
- Share price: ~$23
- Revenue (recent quarter): ~$115M
- Colocation revenue (recent quarter): ~$77.5M (~57% gross margin)
- Net income (recent quarter): ~-$347M (incl. ~$266.5M impairment)
- Liquidity / senior notes: ~$1.04B liquidity; ~$3.3B 7.75% notes due 2031
Core Scientific is valued as a growth-infrastructure story, not on current earnings, since reported results still show large losses tied to the mining-to-AI transition. The market cap reflects the contracted CoreWeave hosting backlog, large deferred revenue (around $654M) and future lease payments (around $3.39B), and the multi-gigawatt power pipeline. Because so much value sits in future contracted capacity, the stock is sensitive to any change in the AI ramp timeline or customer demand.
How do you decide if CORZ is a buy?
Rather than asking whether CORZ is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold CORZ indirectly through an index or sector ETF before adding more.

The bottom line on CORZ
The bottom line: CORZ's story right now is CoreWeave hosting contract and AI colocation, with revenue (recent quarter) at ~$115M. If you believe that narrative continues, the call is about sizing CORZ sensibly and checking overlap with what you own; if you doubt it (the risk: cORZ carries substantial execution and concentration risk: a very large share of contracted future revenue depends on a single customer, CoreWeave, whose own demand and financial health drive the thesis.), it is not for you.

What does Core Scientific (CORZ) do?
+
It operates large US data centers, originally built for bitcoin mining, and is converting that power capacity into hosting AI and high-performance-computing workloads. Its biggest project is a multi-year colocation contract to host AI infrastructure for CoreWeave.
Did CoreWeave acquire Core Scientific?
+

Is CORZ still a bitcoin miner?
+
Less and less. The company has been winding down self-mining, repurposing power for AI hosting, and selling its bitcoin holdings to fund the transition. Bitcoin mining is now a shrinking part of the business relative to its growing colocation revenue.
Why did CORZ report a large loss recently?
+
A recent quarter showed a net loss around $347M, driven largely by a roughly $266.5M non-cash impairment on mining equipment and infrastructure as the company pivots away from self-mining. Revenue was still growing, but the transition costs weighed heavily on reported earnings.
