AI Holders Summary · Q1 2026

MongoDB Inc. (MDB, CUSIP 60937P106) entered Q1 2026 with $17.3B of institutional 13F value held across 784 institutional managers — one of the densest institutional-ownership profiles in mid-to-large-cap enterprise software — reflecting the multi-decade structural shift away from relational databases toward document-based NoSQL and, more recently, vector databases for AI workloads. The quarter's defining activity was a $1.02B reduction from BlackRock, the single largest seller, alongside an open set of buyers including BNP Paribas Asset Management adding $130M in what appears to be a new or newly-initiated position. With conviction-level managers (FMR, Capital Research, T. Rowe Price, Wellington) traditionally among the largest holders and 2 new positions entering or expanding in Q1, MongoDB's holder base reads as a classic institutional-popularity software story: large passive-and-active crossover managers provide breadth, while thematic/conviction technology managers provide concentration at the top. The Q1 rotation pattern is consistent with institutional trimming at the meta-cycle level (BlackRock's treasury/AI infrastructure rotation) while fundamental technology/software managers continue building.

$17.3B institutional 13F value on a company this size reflects near-total broad-index and software-mandate ownership — MDB is not a niche positioning name; it is a standard-issue large-cap software holding.

The BlackRock cut of $1.02B matters because it signals a sleeve-level rotation rather than a company-specific alpha decision — BlackRock manages the equivalent of the entire passive S&P 500, and a large single-quarter cut reflects strategic allocation, not research-on-MongoDB-negative. Meanwhile BNP Paribas' new $130M position adds a European fundamental voice to a predominantly U.S. manager holder base.
