# Soros Added 59 Positions and a $415M XOP Bet: Inside the Q4 2025 Breadth Expansion

> Soros Fund Management expanded 13F value by 22.93% in Q4 2025, added 59 holdings, and launched a $415M XOP position while keeping Amazon as the top core holding.

Soros Fund Management''s Q4 2025 filing is not a small rebalance. The reported 13F book rose to $8.63B, holdings expanded by 59 names, and the biggest new position was a $415M allocation to XOP. The key signal is less concentration and more optionality heading into 2026. TL;DR Scale-up: total reported 13F value increased from $7.02B (Q3) to $8.63B (Q4), a +22.93% move. Breadth: unique holdings rose from 178 to 237 (+59), while top-10 concentration fell 3.46 points. Core + tactical: Amazon stayed #1 while XOP became the largest new add. Interpretation: this looks like a wider opportunity set, not a single-theme concentration bet. Filing Facts and Why This Quarter Matters The official SEC filing for Q4 2025 is accession 0000902664-26-000998 (report date 2025-12-31), filed on 2026-02-13. Prior quarter reference is accession 0000902664-25-005044. You can verify directly on SEC EDGAR: Q4 filing and Q3 filing. For 13F methodology context, see the SEC 13F FAQ: sec.gov. Concentration Compressed While Capital Grew Even as assets grew, concentration moved lower. That combination usually implies managers are finding a broader set of investable dislocations rather than doubling down only in the top bucket. Where Soros Added and Cut the Most The quarter''s largest add was XOP (+$415M), while AMZN also increased. On the other side, exposures such as RSP and FXI were reduced. Read this with filing lag in mind: 13F shows report-date positions, not full intra-quarter trading paths. Portfolio Breadth Shift The transition profile matters: 128 new positions, 69 fully sold, plus 61 increases. This is a high-turnover breadth expansion quarter. How This Fits Broader Filing Season Patterns This quarter''s behavior aligns with the broader filing-season pattern we have been tracking in institutional consensus and manager-specific studies such as Citadel and Millennium: managers are rotating sleeves and distributing risk rather than running one crowded macro expression. Q&A What did Soros buy in Q4 2025? The largest reported new add was XOP (about $415M), alongside other additions like XLE and multiple single-name positions. Did Soros keep Amazon as a core position? Yes. AMZN remained the largest position and increased quarter over quarter. Is Soros more concentrated or more diversified after Q4 2025? More diversified by this snapshot: holdings count increased and top-10 concentration declined from 32.46% to 28.99%.
