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

Core Scientific shares jumped 75.8% in 1H 2026 and are up ~2,000% over 3 years, after its CoreWeave merger was canceled while it continued signing long-term AI data-center power contracts. The company is still cash-burning—free cash flow of -$471M over the last 12 months on $355M revenue—despite raising $3.3B in bonds and building a pipeline of up to 4.5 GW. With the stock trading at a ~$7B market cap on a premium multiple, the article argues the AI growth story is uncertain and suggests avoiding new exposure.

Analysis

The market is likely confusing scarcity value with durable equity value. CORZ can keep monetizing AI demand in the near term, but the real question is whether incremental megawatts earn returns above its funding cost; until that proof point arrives, the stock is a financing story with operating leverage in reverse. In the next 1-3 months, the key catalyst is not another contract headline but whether debt and equity markets remain willing to fund capex without punitive dilution.

Second-order winners are the upstream beneficiaries of the AI buildout, not necessarily the infrastructure intermediary. NVDA captures demand regardless of which power-shell operator wins, while data-center landlords and utilities with cleaner balance sheets should eventually price the same scarcity more efficiently; CORZ is exposed to a future where competition shifts from "who can secure power" to "who can secure cheap capital and interconnects." If power lead times shorten or pricing pressure emerges, the scarcity premium can compress quickly even if AI demand stays strong.

The contrarian risk is that this is still early-cycle and the crowd underestimates how long power remains the bottleneck. That said, the equity is vulnerable if the next quarter shows capex intensity staying elevated, free cash flow remaining deeply negative, or management leaning on more bond issuance to bridge the gap. Over 6-18 months, the thesis breaks if utilization ramps but return on invested capital does not, because the market will eventually treat CORZ less like a growth asset and more like a utility with stale economics.

Key Decisions for Investors

• Short CORZ on strength or via 3-6 month put spreads; this is a tactical negative-carry trade on valuation and dilution risk, not a long-term structural short. Falsifier: a clear inflection to positive operating cash flow or a materially lower capex/MW run-rate.
• Pair trade: long NVDA / short CORZ for 1-3 months as a quality-vs-story hedge. NVDA monetizes AI capex regardless of the power intermediary's financing needs; risk is another wave of scarcity-driven momentum in CORZ.
• Do not chase CORZ on contract headlines alone; wait for the next quarterly report to confirm whether backlog converts into ROIC-positive economics. If gross margins and FCF remain negative despite revenue growth, the multiple should compress.
• Set an alert on funding conditions: any widening in credit spreads or signs of harder refinancing should be used to add to the short, because this model is most exposed when external capital gets expensive.
