The target date market surged in the first half of 2025, with combined assets across mutual funds, CITs, and custom solutions rising 10% to more than $4.7 trillion. Vanguard extended its dominance, adding $121 billion to reach $1.6 trillion, far ahead of Fidelity’s $623 billion. 

A major development is the rapid rise of income-enabled target date funds, whose assets climbed to $103 billion, led by TIAA’s RetirePlus model and BlackRock’s LifePath Paycheck series. 

These products reflect growing demand for pension-like security within modern 401(k) structures, blending glide paths with annuity-based income features. Co-manufacturing partnerships between recordkeepers, insurers, and asset managers are fueling much of this innovation, while CIT-based target date funds have overtaken mutual funds, now holding 53% of assets. 

Finsum: Target date funds are a great way to start a portfolio for clients and then to build customization around the edges.
