BLZE Backblaze, Inc.
Executive Summary
Three mega-passive institutional investors (State Street, Fidelity, Morgan Stanley) collectively added $8.5M in BLZE positions during Q3 2025, bringing total disclosed holdings to $15.0M. The buying is dominated by passive/index rebalancing rather than active fundamental conviction, and the 45-day reporting lag means these positions may have already been adjusted. The cluster is small in scale relative to BLZE's $444M market cap and lacks active manager participation, limiting the signal's trading significance.

Actionable Insight
The cluster is entirely passive/index-driven with no active manager participation, making it a weak standalone signal. Monitor next 13F cycle for active fund entries or exits, which would carry more conviction. The prior neutral report on BLZE (April 2026) saw a +84% T+20 move, but that was likely driven by company-specific catalysts, not institutional positioning patterns.
