Renaissance Technologies Q4 2025: The $64B Quant Giant's Palantir Conviction
Inside Renaissance Technologies' massively dispersed Q4 2025 13F, highlighting their surprising $1.56B top position in Palantir.
The legendary quant firm Renaissance Technologies LLC returned to reporting massive 13F AUM for Q4 2025, revealing a staggering $64.46 billion portfolio. Known for their secretive Medallion Fund and complex algorithmic trading, "RenTech" spreads its bets across a dizzying 3,185 positions.
Algorithmic Dispersion with a Palantir Tilt
True to its quantitative nature, the portfolio is highly dispersed. The top 10 holdings account for only 15.0% of the total value. However, the #1 position is highly notable: a $1.56 billion (3.0%) stake in data analytics firm Palantir Technologies (PLTR). This outsized algorithmic conviction in PLTR suggests their models have identified significant momentum or fundamental anomalies in the stock.
The firm also holds substantial positions in United Therapeutics (UTHR) ($930M) and Micron Technology (MU) ($859M), reflecting a machine-driven approach that aggressively balances biotech volatility with semiconductor cycles.
