Backblaze Surges After Q2 Beat, Raised Outlook, and CoreWeave Deal Tailwind
Backblaze (BLZE) shares rose about 36% after the company reported Q2 results ahead of expectations and raised full-year 2026 guidance. Q2 revenue increased 18% to $42.7M, B2 Cloud Storage revenue rose 34% to $26.6M, and adjusted EBITDA was $12.8M. Backblaze lifted 2026 revenue guidance to $172M-$174M and signed a 5+ year $335M CoreWeave agreement.
How this was made

The 30-second read
Why it matters
The disclosed Q2 beat, positive profitability inflection, and raised full-year revenue and adjusted EBITDA margin guidance create a clear catalyst stack. The CoreWeave contract adds visibility through remaining performance obligations, which can support estimate revisions.
Market read
Traders can treat this as a guidance-and-contract-driven repricing event for BLZE, with the CoreWeave deal providing incremental visibility beyond the quarter.
What to watch
The article does not quantify how quickly CoreWeave volumes translate into revenue or how competitive pricing and churn could affect the raised EBITDA margin guidance.
Background
Backblaze is positioning B2 Cloud Storage as a storage supplier for AI workloads, and the article frames the CoreWeave agreement as a strategic demand driver.
Ticker impact
Backblaze reported Q2 revenue and B2 Cloud Storage growth, raised full-year guidance, and disclosed a 5+ year $335M CoreWeave agreement tailwind.
Likely supports continued upside momentum and upward revisions, though follow-through depends on whether the CoreWeave ramp materializes in near-term bookings.
The article provides specific Q2 results, explicit guidance increases, and a named multi-year CoreWeave deal that should improve visibility via remaining performance obligations.
Market effects
Reinforces the narrative that AI infrastructure demand is flowing to storage providers, potentially lifting sentiment across cloud storage and data infrastructure names.
No specific regional spillover is described beyond US-listed tech/storage sentiment.
AI workload storage demand is global, but the article provides no direct international datapoints.
Counterpoint
The stock’s move may be front-running the CoreWeave deal, while near-term margins and customer ramp timing could lag the market’s expectations.
