Open Philanthropy, a philanthropic partnership established by Giving Pledgers Cari Tuna and Dustin Moskovitz, has announced the launch of a $150 million Regranting Challenge, which will add funding to the grantmaking budgets of one to five programs at other foundations.

To learn from a wide range of grantmakers, add funding to work that is already underway, and pilot a mechanism that enables the most impactful grantmaking programs to grow, the challenge will support high-impact programs with a track record of improving human health, facilitating economic development, and/or addressing climate change. To that end, the foundation aims to roughly double a selected program’s annual grantmaking budget for three years; the entire award may be allocated to a single outstanding funder.

With funding from Open Philanthropy and philanthropist Lucinda Southworth, the challenge will consider both “low-risk” and “high-risk” opportunities, and given its emphasis on cost-effectiveness, the foundation anticipates that the strongest proposals will come from programs that primarily benefit people in low- and lower-middle-income countries.

To be eligible, foundations or programs must have awarded at least $10 million annually for at least the past three years. The deadline to apply is Tuesday, March 15, 2022.
