Why Core Scientific Stock Was Up 75.8% In The First Half of 2026

Core Scientific shares surged 75.8% in 1H 2026 and are up 2,000% over three years, supported by long-term power contracts for AI data centers. However, the company’s fundamentals remain stretched: it generated $355M in revenue over the last 12 months while burning $471M in free cash flow and now trades at a ~$7B market cap, implying premium valuation versus current cash generation. Despite raising $3.3B in bonds and a power-capacity pipeline of up to 4.5GW, the article warns unit economics and AI buildout durability are unclear, suggesting investors should avoid adding at current levels.

Analysis

CORZ is being valued like a scarce AI infrastructure asset, but the economics still look closer to a levered project developer than a software-like compounder. The key distinction is that most of the optionality sits in a capital-intensive backlog that has to be financed, permitted, built, and monetized before it shows up as durable free cash flow; that means the equity is far more sensitive to funding spreads, execution slippage, and customer concentration than to the broader AI narrative.

The second-order winner is not necessarily CORZ but the broader AI hardware stack: GPU vendors and network/interconnect suppliers capture demand earlier in the cycle with less balance-sheet risk, while CORZ bears the working-capital and capex burden. If capital markets tighten even modestly, the market will likely reprice these “AI power” names first because their growth is funded, not self-financed. That makes the current setup fragile: any slowdown in contract conversion or a need for incremental equity/debt could compress the multiple quickly over the next 1-3 months.

The contrarian miss is that a large pipeline is not the same as an economic moat. The market seems to be capitalizing the gross gigawatts rather than the net present value of contracted, funded, and delivered megawatts after interest and maintenance capex. Over 6-18 months, if AI buildout remains strong but hyperscalers internalize more power infrastructure, CORZ’s scarcity premium could fade even while the sector stays hot.

Key Decisions for Investors

• Short CORZ on strength or buy 3-6 month puts after any contract-led rally; the trade works if cash burn persists and no clean path to positive FCF emerges. Falsify if next two quarters show funded backlog conversion plus clear operating cash flow inflection without dilution.
• Pair trade: long NVDA / short CORZ over the next 1-3 months. If AI capex keeps expanding, the cleaner economic rent should accrue to GPU suppliers rather than balance-sheet-intensive power shells; the pair also reduces broad AI beta.
• Avoid initiating a long CORZ until the next filing proves that debt-funded capex is converting into contracted, non-dilutive earnings power. Treat any additional bond issuance or equity financing as a thesis-negative catalyst.
• Set an alert on HY spreads and any guidance change tied to capex or backlog conversion; widening spreads or slower megawatt activation would be the earliest signal that the market is overcapitalizing the pipeline.
