Summary
The MacArthur Foundation, a private foundation based in Chicago, is expanding its allocation to impact investments by 50%, increasing the dedicated pool to $750 million, according to Africa Private Equity News. The foundation said the larger allocation will be implemented beginning in 2027.

As existing investments are repaid, MacArthur will recycle the capital into new investments to further increase its impact. Per the Impact World's weekly coverage, the $750 million commitment equals roughly 7.5% of the foundation's US$9.9bn endowment.

John Palfrey, president of the MacArthur Foundation, said expanding impact investing allows the foundation to make "more meaningful progress against the challenges facing our world." He described impact investments as an important way to advance the mission alongside charitable giving and the foundation's values-aligned endowment portfolios.

Debra Schwartz, managing director for impact investments at MacArthur, said the foundation will combine the larger impact allocation with grantmaking and sustainable investing to do more for people and places globally. She also said MacArthur looks forward to mobilizing greater investment through collaboration with foundations, families and others deploying assets across the full continuum of capital.
