Billionaire investor George Soros made major changes to his U.S. stock portfolio in the fourth quarter of 2025, boosting bets on AI chip and megacap tech companies.
With the tech-heavy Nasdaq Composite down about 1.8% year to date, perhaps his fund’s recent moves can offer investors some hints.
Soros is a legendary hedge fund manager who is best known for his $1 billion bet against the British pound in 1992, one of the most famous currency trades in history.
Born in Hungary in 1930, Soros survived the Nazi occupation before moving to England and later to the United States in the 1950s, where he built his fortune and helped reshape the modern hedge fund industry.
His other notable market moves include building short positions against the Thai baht during the 1997 Asian financial crisis and the Japanese yen in 2013 and 2014.
Soros founded Soros Fund Management in 1970, and he is now the fund’s chair.

Soros increases bets on AI semiconductors
Semiconductor and AI infrastructure names were among the biggest bets of Soros’ portfolio in Q4, 2025, according to data from Whalewhisdom based on 13F filings.
Soros Fund Management significantly increased its stake in Taiwan Semiconductor (TSM), adding 213,766 shares and lifting the position by 157% during the quarter.

Taiwan Semiconductor, also known as TSMC, is the world’s largest chip foundry and a critical manufacturer for Nvidia, AMD, and Broadcom.
On Jan. 15, TSMC posted strong fourth-quarter results, as diluted EPS per ADR rose 35% year over year to $3.14. Revenue for the quarter reached $33.73 billion, up 25.5% year-over-year. Gross margin, a key profitability measure, was 62.3%, up from the 59.5% a year ago.
Soros Fund also added 117,973 shares of Nvidia, up 21.5%. That chunk of stocks is valued at roughly $22 million as of Feb. 18.
He initiated new positions in Broadcom (AVGO) and Advanced Micro Devices (AMD), adding 102,379 shares and 17,201 shares, respectively.
In total, Soros added roughly $137 million worth of these four semiconductor names in the fourth quarter of 2025.
The semiconductor sector, as tracked by the iShares Semiconductor ETF (SOXX), is up more than 60% over the past 12 months, while demand tied to hyperscaler capital spending is expected to remain a growth driver for chipmakers.
As Microsoft (MSFT), Alphabet (GOOGL), Amazon (AMZN) and Meta (META) stated in their latest earnings, the four megacap tech leaders are on track to spend more than $650 billion on artificial intelligence this year.
Soros adds megacap tech stocks, cuts software
Beyond semiconductors, Soros also added to several megacap tech companies in Q4.
Amazon remained the fund’s largest holding, and the position was modestly increased by 6%, adding 133,385 shares during the quarter.

Soros added 161,298 shares of Microsoft, lifting the stake by 158.53%, one of the sharpest increases in the portfolio. This was likely a buy-the-dip move as Microsoft stock dropped more than 5% during the fourth quarter, Morningstar data shows.
He added 66,503 shares of Apple (AAPL) and initiated a stake in Tesla (TELS), buying 56,661 shares.
Soros also initiated a new position in Coinbase (COIN) as the crypto market fell sharply.
On the sell side, Soros reduced exposure to some software companies and one megacap company.
Soros trimmed his Alphabet stake by 2.9% in the fourth quarter, selling 19,300 shares as the stock rose 31.7% during the period, likely taking profits. Alphabet remains the fund’s fourth-largest holding despite the selling.

The fund cut its Snowflake (SNOW) stake by about 65% and trimmed its Datadog (DDOG) stake, while fully exiting its Intuit (INTU) stake.
Software stocks have been among the worst performers in 2026, with investors questioning whether AI tools could pressure traditional software business models and slow their growth. The software sector tracked by iShares Expanded Tech-Software Sector ETF (IGV) is down 23% year-to-date.
Among other moves, Soros added to UnitedHealth (UNH) and initiated a new position in Eli Lilly (LLY), two hot names in the healthcare sector, which is often considered defensive as the demand for healthcare products and services is relatively stable.
The fund also increased its stakes in Uber (UBER), DoorDash (DASH), and Disney (DIS).
