Overview - /Benchmarks and indices built on science
Knowing how a private markets asset or fund truly performs against the market is what drives genuinely informed decisions on manager selection, asset allocation and risk. But in private markets, that level of transparency is not easy to find.
Scientific Infra & Private Assets (SIPA) indices and benchmarks are built to answer that question, with over 1,100 indices available across private infrastructure and private equity, and more than 20 million datapoints accessible via APIs.
Drawing on one million private asset prices computed each month from actual transaction data, they provide the robustness and granularity needed to benchmark performance with real confidence. This supports manager selection, risk reporting, peer comparison and asset valuation with data that holds up to scrutiny.
The product of more than a decade of academic research at the EDHEC Infrastructure & Private Assets Research Institute, SIPA joined PEI Group in March 2026, bringing independent, scientifically grounded performance benchmarks and indices that set the standard across private infrastructure and private equity.
Investors with more than USD 1 trillion in private assets AUM already rely on this data.
