Explore the new research report from Tideline, ILPA, and Campbell Lutyens

As impact investing continues to mature, institutional investors are asking a critical question: how institutionalized is the market today — and what still needs to change? Impact Investing: The State of Market Institutionalization examines the current state of practice across private markets, identifying both meaningful progress and persistent gaps that must be addressed to support long-term scale and credibility.

Drawing on insights from leading Limited Partners, fund managers, and advisors, the report assesses how far impact investing has come in areas such as governance, strategy, measurement, and alignment with fiduciary responsibilities. It highlights where practices are converging — and where fragmentation, inconsistency, or lack of clarity continue to limit adoption by mainstream institutional capital.

Positioned as the starting point of an ongoing research effort, this report calls for coordinated action across the ecosystem. ILPA, Tideline, and Campbell Lutyens invite practitioners to engage with the findings, share feedback, and contribute to the collective work needed to close the gaps identified.

Featuring original analysis and practical insights grounded in institutional investor perspectives, Impact Investing: The State of Market Institutionalization is essential reading for LPs, GPs, and market builders committed to strengthening impact investing as a durable, institutional-grade asset class.
