MONGODB INC
915 institutions still hold MONGODB INC as of Q2 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
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.
