The filing shows a 65% rise from $1.80T in 2023Q3, led by mega-cap exposures and a top-5 concentration of 24.3%. TL;DR STATE STREET CORP reported $2.98T in Q4 2025 13F AUM, with 500 positions and a WhaleScore of 70.50. The top holding was NVDA at 6.81% ($184.91B), while top-5 concentration reached 24.3%. From 2023Q3 to 2025Q4, disclosed AUM rose from $1.80T to $2.98T, a roughly 65% increase across two years. State Street’s latest 13F underscores what scale looks like when custody infrastructure, index franchise depth, and ETF distribution all reinforce each other. In Q4 2025, the firm disclosed $2.98T in 13F AUM and 500 positions, with mega-cap US equities still doing most of the heavy lifting. You can track the full filer profile here: STATE STREET CORP on 13F Insight. Q4 2025 snapshot: giant book, measured concentration The portfolio remains huge but not hyper-concentrated. The top-5 names account for 24.3% of disclosed value, leaving the majority spread across hundreds of additional holdings. That is consistent with State Street’s role as a core market plumbing institution and the creator of the SPDR ETF family, where breadth and benchmark exposure often matter as much as single-security conviction. At the single-name level, the largest weights were concentrated in US mega-cap tech and platform leaders, including NVDA, AAPL, MSFT, AMZN, and GOOGL. This keeps the portfolio’s risk and return profile tightly linked to the largest index constituents. Why the $2.98T headline matters The most important signal in this filing is not a dramatic quarter-to-quarter turnover event. It is the persistence of scale. State Street’s disclosed 13F AUM reached $2.98T in Q4 2025, up from $1.80T in 2023Q3, while maintaining one of the longest track records in the dataset at 87 quarters. For allocators, that kind of longitudinal consistency makes this filing more useful as a structural read than as a short-term trading map. Recent corporate updates also align with that interpretation. During 2025, State Street Investment Management announced additional SPDR product initiatives and distribution updates, while media coverage on quarterly earnings emphasized fee resilience and normal pressure on interest-sensitive lines. Together, those themes point to a business leaning into fee-based scale rather than relying on one macro regime. History shows a strong uptrend with one reset quarter The last eight quarters in the canonical history show a broad climb from $2.24T in 2024Q1 to $2.98T in 2025Q4. The only notable interruption was 2025Q1 (-4.3% QoQ), followed by a strong rebound in 2025Q2 and 2025Q3. Q4 then added another +3.4% QoQ to print a new high. Interpretation for investors following smart-money signals For readers tracking institutional behavior, State Street’s filing is best read as a benchmark-scale positioning barometer. A top position in NVDA at $184.91B does not automatically imply high-conviction active stock picking in the hedge-fund sense. Instead, it more likely reflects how mega-cap leadership has propagated through custody and index-linked channels. That distinction matters when comparing filers. A concentrated fundamental manager and a custodian-linked giant can report similarly large stakes for very different reasons. If you are building watchlists from 13F data, use State Street as a reference for market structure and concentration drift, then pair it with more concentrated active filers for idea generation. Bottom line Q4 2025 reinforces State Street’s profile as a compounding scale institution: $2.98T in disclosed AUM, 500 positions, a still-manageable 24.3% top-5 concentration, and a two-year rise of roughly 65% from 2023Q3. For 13F users, this is less a tactical signal and more a high-quality read on where systemic equity exposure sits at quarter-end.
