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

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: WULF is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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 WULF 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 WULF 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.

TeraWulf Inc. (NASDAQ: WULF) operates data center infrastructure powered largely by low-cost, predominantly zero-carbon energy at its Lake Mariner campus in western New York. Historically it made money by mining bitcoin: running specialized computers to earn block rewards, with revenue tied directly to bitcoin's price and network difficulty. Increasingly it makes money a different way, by leasing turn-key, power-backed data center space to high-performance-computing and AI customers under long-term colocation agreements, where the customer brings the chips and TeraWulf provides the building, power, and operations in exchange for contracted rent.

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.
• WULF drivers: Contracted, hyperscaler-backed AI leases; Scarce energized power as the moat.

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 WULF, teraWulf still carries meaningful bitcoin price exposure through its remaining mining operations, so crypto weakness pressures part of the business.

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; WULF 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 WULF 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.

WULF. TeraWulf is valued on contracted future AI hosting capacity far more than on current earnings, which remain negative as it spends heavily to build. The market capitalization reflects the long-dated Fluidstack and Core42 leases and the Google backstop, so the figures swing with bitcoin sentiment, AI infrastructure enthusiasm, and construction milestones. All figures are approximate and drawn from Q1 2026 disclosures.

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); WULF shows revenue (q1 2026) ~$34 million total, including ~$21 million HPC lease revenue, energized hpc capacity ~60 MW critical IT at Lake Mariner; ~594 MW contracted, cash and restricted cash ~$3.1 billion as of March 31, 2026, total debt ~$5.8 billion (incl. ~$2.5B convertibles, ~$3.2B senior secured notes).

CORZ and WULF 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.
