Core Scientific's AI Pivot Shows Progress, But Concentration and Unleased MW Risks Linger

What happened

A bullish Seeking Alpha article highlights Core Scientific's successful transition to AI colocation, with Q1 colocation revenue surging to $77.5M and gross margins of 57%, supported by a multi-gigawatt power pipeline and an expanded CoreWeave partnership. However, the DeepValue master report, based on SEC filings, reveals that this progress is heavily concentrated: 67% of total revenue comes from a single colocation customer (CoreWeave), and while billable MW rose to 225 MW, unleased MW expanded to 685 MW—meaning capacity is being built faster than it is contracted. The company faces significant liquidity pressure, with $1.47B in near-term contractual commitments, $389.2M in Q1 capex, and a highly secured capital stack including $3.3B in 7.75% notes with an uncapped completion guarantee. The bull case depends on signing additional large customers to absorb the unleased MW and reduce concentration, while the bear case sees utility collateral and construction delays tightening liquidity. The stock at ~$29 reflects the AI narrative, but the WAIT rating is justified until leased MW increases beyond 590 MW and single-customer revenue falls below 50%.

Implication

For investors, the bullish AI pivot is real but not yet de-risked. The key variable is customer diversification: without new signed large HPC tenants, the 685 MW unleased inventory remains a merchant risk that could squeeze margins and liquidity. The completion guarantee and $80M restricted escrow add downside if construction timelines slip. Position sizing should reflect this asymmetric risk. Only add to positions if the next 10-Q shows leased MW above 590 MW and top-customer revenue below 50%, or if the stock pulls back below $24 (attractive entry per the report).

Thesis delta

The article reinforces the AI pivot narrative, but the master report's granular data shows the pivot's success is still highly dependent on CoreWeave and that the capacity buildout is outpacing demand contracts. The bullish case remains intact only if CORZ can demonstrate multi-customer absorption in the next two quarters; otherwise, the risk of merchant capacity and liquidity drag is higher than the article suggests.
