BlackRock Adds Private Assets to 401(k) Plans

BlackRock announced a push around mid-2026 to add private equity and private credit investments to employer-sponsored 401(k) retirement plans. The strategy aims to help everyday retirement savers navigate an increasingly concentrated public stock market.

The initial rollout will run through target-date mutual funds managed by Great Gray Trust. These products will invest between 5% and 20% of their total capital into privately owned businesses. Access will depend on whether plan sponsors and administrators decide to include the strategy for their employees.

BlackRock estimates that privately owned ventures deliver about 50 basis points more in annual returns than conventional stocks. According to the firm, this premium could produce retirement account balances roughly 15% higher over a 40-year investment period compared with purely stock-based portfolios.

The move comes amid heavy concentration in public markets, where the 10 largest companies in the S&P 500 now account for nearly 40% of the entire index value. BlackRock's new structure seeks to deliver better diversification as demand grows for alternatives outside the public markets.
