As of Q2 2026, 30 SEC-registered investment managers reported holding PUBM (PUBMATIC INC) in their latest 13F filings, with a combined reported value of $125.64M across 9.61M shares. That is +0.2% by share count (+17.40K shares) versus the previous quarter, while reported value moved +60.7%. Ownership is concentrated: the five largest holders account for 69.7% of reported value and the top ten for 83.7%.

Compared with the prior quarter, 1 opened new positions, 16 added to existing stakes, 12 trimmed. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

PUBM is classified in the Technology sector.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
