CORZ vs IOND: Which Is the Better Buy in 2026?

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CORZ and IOND share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CORZ and IOND exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

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.

Ionic Digital Inc. was formed in January 2024 to hold the mining assets of Celsius Network, which filed for Chapter 11 in July 2022. Those assets included mining hardware, power contracts, real estate and roughly ~540 bitcoin, and the equity went to former Celsius creditors as part of the bankruptcy plan. Since then the company has pivoted hard: rather than run its own machines against a falling hashprice, it leases energized capacity at its Ward County, Texas campus to an AI cloud operator. The centerpiece is a triple-net lease with Nscale covering roughly ~323 MW of contracted capacity across about a decade and roughly ~$2.6 billion of contracted revenue, under which the tenant carries rent plus operating costs including taxes, insurance and maintenance. Legacy self-mining continues at roughly ~12.2 EH/s, a fraction of what larger operators run, and its contribution is shrinking fast by design.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CORZ drivers: CoreWeave hosting contract and AI colocation; Power pipeline and capacity expansion.
• IOND drivers: The Nscale triple-net lease; Energizing the remaining power pipeline.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: 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. For IOND, tenant concentration is the dominant risk: a single lease with Nscale accounts for the overwhelming majority of contracted revenue, so the tenant's own funding, credit standing and demand outlook effectively become Ionic Digital's.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CORZ if you believe its drivers more; IOND if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CORZ and IOND guides.

CORZ. 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.

IOND. With no positive earnings, there is no meaningful price-to-earnings figure, so the stock is generally framed on sales and EBITDA. Roughly ~$2.8 billion of market value against ~$152 million of trailing revenue works out near ~18 times sales, falling to about ~15 times on the midpoint of 2026 guidance and roughly ~20 times the midpoint of guided adjusted EBITDA. Those multiples sit well above legacy bitcoin miners and closer to data center and neocloud infrastructure names, which is consistent with a business whose contracted backlog of roughly ~$2.6 billion dwarfs its current annual revenue.

Headline figures (approximate, JULY 2026): CORZ shows market cap ~$7.5B, share price ~$23, revenue (recent quarter) ~$115M, colocation revenue (recent quarter) ~$77.5M (~57% gross margin); IOND shows revenue (ttm) ~$152 million, net income (ttm) ~-$233 million (EPS ~-$6.23), fy2026 revenue guidance ~$190 million to ~$195 million, fy2026 adjusted ebitda guidance ~$137.5 million to ~$142.5 million.

CORZ and IOND are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CORZ and IOND exposure against your real portfolio. It is not an investment adviser.
