MSCI Inc. introduced its first benchmark that blends public and private equity exposure on December 4, 2025, combining its flagship MSCI ACWI IMI with a proprietary private‑equity component derived from LP‑sourced cash flows and valuations of nearly 10,000 private‑equity funds.
The new MSCI All Country Public + Private Equity Index allocates 15 % to private equity and is calculated daily using a drifted‑weight methodology, with quarterly rebalancing to maintain the target allocation. The index offers a single‑framework view of total equity exposure, enabling investors to benchmark and allocate across both public and private markets within a familiar index structure.
By launching this benchmark, MSCI taps a private‑markets asset class projected to exceed $1.5 trillion in AUM, addressing a clear investor demand for transparent private‑market exposure. The move positions MSCI to capture a share of a rapidly expanding market that has historically lacked standardized benchmarks.
MSCI’s competitive advantage lies in its ability to combine high‑quality public‑market data with proprietary private‑equity analytics, a capability that rivals have not yet matched. The integration also supports MSCI’s broader strategy to diversify beyond traditional index licensing into AI‑driven private‑market solutions, leveraging its data‑rich platform to deliver deeper insights and automation.
Luke Flemmer, Head of Private Assets at MSCI, said the launch “is a milestone in our mission to make private markets more transparent and accessible,” adding that the benchmark extends MSCI’s private‑assets toolkit and offers investors a simpler way to benchmark, allocate, and access private capital.
The index launch is part of MSCI’s larger push to democratize private markets, which are becoming increasingly accessible to high‑net‑worth and retail investors through semi‑liquid and evergreen vehicles. By providing a standardized, transparent framework, MSCI addresses a long‑standing gap in private‑market data and benchmarking, positioning itself as a leader in this emerging space.
Private‑market growth projections—ranging from $1.67 trillion by 2033 to $1.35 trillion by 2034—underscore the strategic timing of the launch. MSCI’s AI‑powered data platform is expected to accelerate the adoption of the benchmark, while the integration of public and private exposure offers investors a more holistic view of equity performance.
In summary, MSCI’s integrated public‑and‑private equity index signals a strategic shift toward providing comprehensive equity exposure, opening new revenue opportunities and reinforcing the firm’s leadership in data‑driven market analytics.
