Backblaze (BLZE) shares surged 20% Tuesday following the cloud storage provider’s announcement of a five-year, $335 million data storage partnership with CoreWeave (CRWV).
The agreement encompasses a multi-exabyte commitment, translating to millions of terabytes in total storage volume. Backblaze will deliver economical storage capacity designed to support key components of CoreWeave’s managed infrastructure ecosystem.
This collaboration focuses on HDD-based storage tiers integrated within CoreWeave AI Object Storage. Backblaze’s infrastructure will enhance data placement optimization across various performance tiers, allowing high-performance storage resources to remain dedicated to demanding AI computing tasks.
A significant advantage for existing users: customers currently leveraging CoreWeave AI Object Storage with its proprietary LOTA distributed cache technology will gain instant access to expanded service tiers without requiring any code adjustments.
Agreement Scope and Coverage
The storage framework is engineered to accommodate various phases of AI development and deployment. This encompasses model training sessions, inference operations, checkpointing processes, data preparation workflows, model output management, and retrieval-augmented generation (RAG) applications.
Backblaze CEO Gleb Budman emphasized the critical nature of storage: “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 driving the partnership decision.
Backblaze maintains a global customer base exceeding 100,000 organizations and has developed 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 platform encompassing infrastructure, technology solutions, tools, and managed services. Its client portfolio spans premier AI model developers, enterprise organizations, and academic research institutions.
The platform serves 9 of the 10 leading AI model providers worldwide — a metric that underscores the substantial storage requirements this partnership aims to address.
CoreWeave (CRWV) shares moved inversely 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 gain represents one of the stock’s most substantial single-session advances in recent trading history.
The five-year agreement duration extends through approximately 2031, establishing a secured long-term revenue channel for Backblaze.
