AI Holders Summary · Q2 2026

Institutional sentiment on IonQ Inc (IONQ) ran nearly one-way in Q2 2026 — a single modest seller against a $94.6 million, 71-holder base — and the largest position in the stock grew almost entirely on price. UNICOM Systems, Inc. holds $41.0 million (43.3% of total institutional value) with its share count completely unchanged at 768,900 shares — yet the position's dollar value rose $18.8 million this quarter on the stock's own price gain. Hamilton Lane Advisors shows the identical pattern at smaller scale: unchanged at 195,000 shares, its stake still gained $4.8 million in value. Real buying is happening too: Benin Management Corp increased its stake 262.5% (a genuine $1.3 million addition, the largest true buy), and Zevenbergen Capital Investments opened a substantial new $10.7 million position. Ten firms opened brand-new positions this quarter, while the only meaningful seller, Milestone Asset Management, trimmed just 17.9% (-$230,562) — a genuinely one-sided quarter for institutional sentiment.

The largest holders didn't trade — the stock did the work

UNICOM Systems, Inc. is the dominant holder at $41.0 million, or 43.3% of total institutional value, with a share count that hasn't budged from 768,900. Yet that position's dollar value rose $18.8 million this quarter — entirely a function of IonQ's own price appreciation, not any decision by UNICOM Systems. Hamilton Lane Advisors shows the same pattern on a smaller scale: unchanged at 195,000 shares, its position still gained $4.8 million in value. Together, these two static holders account for $23.5 million in quarter-over-quarter value growth without a single share changing hands.
