# Tiger Global +42.47% but 13-Point De-Crowding: The Q4 2025 Mega-Cap Rebalance

> Tiger Global's Q4 2025 13F rose 42.47% in value while top-10 concentration dropped 13.06 points, led by large new stakes in MSFT, AMZN, TTWO, and TSM.

Tiger Global''s Q4 2025 filing is a classic paradox quarter: the book grew sharply, but concentration dropped hard. Reported 13F value rose from $20.86B to $29.71B (+42.47%), while top-10 concentration fell from 75.81% to 62.75%. That is a meaningful de-crowding signal. TL;DR Book growth: +$8.86B quarter over quarter, reaching $29.71B. Concentration reset: top-10 weight dropped 13.06 points. Largest new adds: MSFT, AMZN, TTWO, and TSM. Takeaway: less dependence on a narrow top bucket despite larger gross exposure. Filing Facts Q4 filing accession: 0000919574-26-001143 (filed 2026-02-17). Q3 reference: 0000919574-25-006931. SEC EDGAR references: Q4 filing and Q3 filing. De-Crowding in the Top Bucket Top-1, top-2, top-5, and top-10 concentration all declined materially. That pattern is often more informative than raw AUM growth because it reflects portfolio construction choices under uncertainty. Where Capital Was Reallocated The quarter introduced large new positions in Microsoft, Amazon, Take-Two, and TSM. Meanwhile, prior heavyweights such as SE and APP were trimmed. This is a high-conviction redistribution, not a passive drift. Transition Structure Only 2 names were fully sold, while 17 were newly introduced and 26 reduced. That mix points to active sleeve rotation rather than wholesale liquidation. Cross-Read with Other Q4 Manager Patterns Tiger''s de-crowding sits in the same family as recent manager shifts we tracked in D. E. Shaw, Appaloosa, and Millennium: the message is that managers can increase notional exposure while reducing crowding risk. Q&A What did Tiger Global buy in Q4 2025? The largest reported new stakes were MSFT, AMZN, TTWO, and TSM. Did Tiger Global reduce AI-heavy concentration? On a portfolio-construction basis, yes. Top-10 concentration fell by 13.06 points despite overall value growth. Is this risk-off? Not by this 13F snapshot. It reads more like risk redistribution across a wider top bucket.
