AI Holders Summary · Q1 2026

Tempus AI's Q2 2026 tracked ownership is small but sharply concentrated: Versant Capital Management owns about .6K, roughly 86% of the .1K snapshot, MassMutual Private Wealth & Trust owns about 12%, and Kerr Financial Planning about 1%. The concrete change is that both meaningful holders added from tiny bases—Versant increased from 81 to 270 shares and MassMutual from 4 to 39—so TEM's visible footprint expanded without becoming broad.
