CoreWeave

CoreWeave (CRWV) trades on the Nasdaq. It priced its IPO at $40 a share on March 27, 2025, selling 37.5 million shares — cut down from a planned 49 million at $47–$55 — for $1.5 billion, the largest US tech offering since 2021. The stock opened at $39 and closed at $40 on debut day, flat, in what the coverage record called a downsized, lackluster listing.

The company rents out Nvidia GPUs by the hour. It began as an Ethereum-mining operation, pivoted to GPU cloud computing once Ethereum moved off proof-of-work, and by mid-2023 was already renting to Microsoft: 700 clients, a $2 billion valuation, fewer than 250 staff. Nvidia is not a bystander in any of this. It supplies the chips, holds an equity stake (5.96% at IPO, built through a $250 million anchor order, then a further $2 billion investment in January 2026), and — since September 2025 — has agreed to buy back any cloud capacity CoreWeave can’t sell to anyone else, guaranteed through April 2032, for $6.3 billion. Little independent analysis exists on a company that has only traded publicly since March 2025. That is what makes it a fit for the assembly job below: pulling the scattered record — S-1 disclosures, earnings, financing filings, discussion threads — into one place. See The AI Capex Supercycle for the spending cycle CoreWeave sits inside.

TEXXR’s corpus carries a CoreWeave mention as early as November 12, 2021, describing “a specialized cloud service for GPU-based workloads” — three and a half years before the IPO. Coverage stayed thin through 2023 and 2024, tracking a company signing $2.3 billion in Nvidia-collateralized debt and, later, roughly $10 billion in contracts with Microsoft running through 2030. The volume didn’t move until the IPO quarter, and the corpus’s own quarterly count shows the jump plainly (see What to Watch’s baseline below).

The IPO surfaced the dependency at the center of the company. CoreWeave’s S-1 disclosed that Microsoft made up 62% of 2024 revenue, with the top two customers together accounting for 77% of $1.9 billion in sales. Days before the filing, CoreWeave denied a Financial Times report that Microsoft had walked back some agreements; the record separately shows Microsoft passing on a roughly $12 billion capacity option that OpenAI then picked up. FT coverage the same week framed CoreWeave’s debt — near $7.5 billion coming due by the end of 2026, against thin operating cash flow — as requiring investors to take “a leap of faith,” and compared the structure to WeWork’s.

What followed reads as a customer-diversification campaign run in public. OpenAI signed an $11.9 billion, five-year contract weeks before the IPO, taking $350 million of CoreWeave stock through a private placement. Meta signed for $14.2 billion in September 2025, then added $21 billion more in April 2026, running 2027 through 2032. Anthropic signed its first CoreWeave deal in April 2026. Jane Street — not an AI lab — committed roughly $6 billion in compute spend and took a $1 billion equity stake the same month. By May 2026, OpenAI’s compute commitments had left it holding roughly $2.6 billion of combined CoreWeave and Cerebras stock: a supplier it pays, that it now partly owns — see Cerebras’s report for the other half of that stake.

The market never took the diversification story cleanly. CoreWeave tried to vertically integrate by buying data-center operator Core Scientific for $9 billion in July 2025; Core Scientific’s own shareholders voted the deal down that October. A month before that vote, CEO Michael Intrator’s disclosure of construction delays at a data-center provider sent CRWV down 16.3% in a single session. By mid-December 2025, the Wall Street Journal tallied a $33 billion market-value loss over six weeks, compounded by short-seller Jim Chanos’s public bet against the stock. Q1 2026 earnings, reported in May, beat estimates — revenue up 112% year over year to $2.08 billion, with a $99.4 billion backlog — but a light Q2 forecast still dropped shares roughly 10% in the same session. Founders, meanwhile, have sold $2.3 billion of stock since the lockup lifted in August 2025, cutting their combined stake by close to a quarter. Nvidia’s own August 2025 earnings benefited from the trade: CFO Colette Kress attributed part of a $2.2 billion “net other income” gain to its CoreWeave equity — a gain that coverage noted would, on its own, rank as roughly the 44th most profitable member of the S&P 500. See Nvidia for the supplier side of that relationship.

267 hyperedges touch CoreWeave in TEXXR’s knowledge graph. Financial edges dominate at 52.4%, partnership at 13.9% — two-thirds of everything extracted about the company, ahead of controversy (12.4%) and acquisition (9.4%). Running CoreWeave, Nvidia, Microsoft, and OpenAI as a four-entity constellation turns up 98 edges across 24 months, and every entity connects to every other: no isolated node, a genuinely closed circuit rather than a hub with spokes.

The graph also holds a thread worth naming rather than hiding, because it’s flagged, not confirmed. A widely discussed November 2025 commentary, logged beside the coverage of CoreWeave’s 16.3% single-day drop, characterized its customer base as effectively five names: OpenAI, Microsoft (mostly reselling to OpenAI), Google, Meta, and Nvidia. TEXXR’s graph carries that claim tagged as rumored commentary, not a confirmed fact — the difference between what a filing says and what a trader on the timeline says matters, and the record keeps them apart.

Positioning: how much of CRWV is sold short, on the record brokers file twice a month. It lags by design — read it as where the crowd stood, not where it stands.

Order flow is signed before it becomes revenue — the earliest of the three views. From the capital-flow ledger.

• The coverage baseline itself. TEXXR’s quarterly article count for CoreWeave sat at a single article in 2023Q4 and one again in 2024Q1. It reached 17 in the IPO quarter (2025Q1), then peaked twice more at 16 (2025Q3, 2026Q2) — a 16- to 17-fold jump from the pre-IPO baseline, tracked quarter by quarter in the corpus rather than asserted after the fact.
• Customer concentration in the next 10-Q. The S-1’s 62%/77% Microsoft-led concentration is the number to hold against future filings — not press releases about new deals, but the disclosed share of revenue.
• The SPV and GPU-backed debt structure. CoreWeave pioneered financing data centers through special-purpose vehicles that move debt off its balance sheet; one analysis sized its total at $2.6 billion against Oracle’s $66 billion and Meta’s $30 billion in the same comparison. Whether that gap closes, and how, is a structural signal.
• The backlog-to-guidance gap. A $99.4 billion backlog next to a Q2 2026 forecast that missed estimates is the tension to track quarter over quarter.
• Insider selling pace. Founders sold $2.3 billion of stock since the August 2025 lockup expired; whether that rate holds, slows, or accelerates is in the filing record, not in guesswork.
• Derivatives exposure. Reuters reported in July 2026 that CoreWeave was exploring hedges against falling memory and storage chip prices — a new instrument layered onto a company already carrying GPU-collateralized debt.
