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.
