Shares of Backblaze (BLZE) experienced a dramatic 20% surge on Tuesday after the cloud storage provider revealed a significant five-year data storage partnership valued at $335 million with CoreWeave (CRWV).
The agreement is characterized as a multi-exabyte commitment, representing data volumes measured in millions of terabytes. Under the terms, Backblaze will deliver economical storage capacity to power select components of CoreWeave’s managed storage ecosystem.
The collaboration focuses on integrating HDD-based storage layers within CoreWeave AI Object Storage. Backblaze’s infrastructure will enhance data placement optimization across various performance tiers, allowing high-performance storage resources to remain available for the most demanding AI computational tasks.
A significant advantage for current users: organizations already leveraging CoreWeave AI Object Storage through its proprietary LOTA distributed cache technology will gain instant access to additional service tiers without requiring any code updates.
Partnership Scope and Details
The storage framework is designed to accommodate various phases of AI development and deployment. This encompasses model training operations, inference processing, checkpoint management, data preparation workflows, model output storage, and retrieval-augmented generation (RAG) applications.
Backblaze CEO Gleb Budman emphasized the critical nature of the partnership: “Storage is the foundation every AI workflow is built on — without it, even the world’s most powerful compute sits idle.”
CoreWeave VP Nick Hoover highlighted Backblaze’s proven expertise in managing sophisticated HDD-based infrastructure at enterprise scale as a primary factor behind selecting the partnership.
Backblaze maintains a global customer base exceeding 100,000 organizations and has engineered its platform specifically for large-scale, economically efficient storage tailored to enterprise and data-heavy applications.
CoreWeave’s Market Standing
CoreWeave operates a comprehensive AI cloud infrastructure that encompasses hardware, technology platforms, development tools, and professional services. The company serves a diverse clientele including prominent AI model developers, enterprise organizations, and academic research institutions.
With 9 of the top 10 AI model providers as active customers, CoreWeave’s market position underscores the substantial storage requirements this partnership aims to address.
Interestingly, CoreWeave (CRWV) stock moved inversely on Tuesday, declining 5.65% during the trading session.
BLZE shares retreated 0.85% in after-hours trading following the initial rally, though the 20% intraday jump represented one of the most significant single-session gains for the stock in recent periods.
The five-year duration of this agreement extends through approximately 2031, establishing a substantial long-term revenue pipeline for Backblaze.
