AI Holders Summary · Q1 2026

Brilliant Earth Group Inc. (BRLT, CUSIP 109504100) entered Q1 2026 with a materially under-threshold institutional 13F reading — approximately $0B of reported institutional 13F value across just 36 holders and eight new positions opened simultaneously in the quarter, making this the most holder-base-transformation event in this batch at the small-cap density tier. The 8-new-in-36 pattern represents a 22% addition to the holder universe in a single quarter, and it is consistent with either a thematic luxury-consumer or digitally-native vertical-commerce manager cohort discovering the name at the same time, or a single lead manager's distribution of an initial position across multiple managed accounts. BRLT's business model — online jewelry retail with lab-grown-diamond sourcing and direct-to-consumer transparency positioning — addresses a durable consumer-trend tailwind (lab-grown diamond penetration accelerating), but the company's scale and public-market profile remain in the small-cap entry zone where institutional coverage builds incrementally. For smart-money trackers, BRLT is at the early-stage-institutional-coverage inflection point rather than at a conviction or rotation decision point — this quarter's 8-new-position event is the IQ-relevant signal, not Q/Q dollar change.
