Which nonprofit became the administrative secretariat for America250 in 2018?

The American Battlefield Trust became the administrative secretariat for America250 in 2018.

The U.S. Department of the Interior issued a request for proposals in 2017 seeking a nonprofit to support the United States Semiquincentennial Commission. The American Battlefield Trust was selected in 2018, providing financial, staffing, legal, governance, and strategic support as the commission became operational.

The Trust also helped create the America250 Foundation and assisted with relationships involving federal agencies, stakeholders, and potential corporate supporters. It is a separate organization from the National Park Service, which has supported commission funding arrangements, and from the Daughters of the American Revolution, which supported a commemorative tree project in Philadelphia. The secretariat role concerns administration and coordination, not ownership of the national anniversary itself.
