King of Prussia is pitching a stadium as the flashy new anchor for a nearly $200 million makeover of one of its long-standing office-park districts. The proposed 7,500-seat venue could bring minor league baseball, professional women’s soccer, concerts and community events to Moore Park—but the financing is still very much in the proposal stage.
According to Bisnow, Upper Merion Township leaders envision the stadium on a 16.8-acre Moore Park site, with the venue serving as the centerpiece of a broader redevelopment plan. The project emerged through an application seeking $20 million from Pennsylvania’s Redevelopment Assistance Capital Program, or RACP.
The Stadium Plan Has A Complicated Capital Stack
Pennsylvania’s Office of the Budget describes RACP as a grant program for major regional economic, civic, cultural and recreational projects. The program requires projects to demonstrate regional impact and at least 50% non-state financial participation, while the current funding round is closed and its next application window has not been set, according to the Pennsylvania Office of the Budget.
The application outlines a $197 million project budget, including $55 million in proposed state participation, $31 million from Montgomery County and $35 million from Upper Merion Township over 30 years. The remaining $56 million would come from private sources such as team rent, sponsorships and donations, with construction targeted for later this year and completion projected in 2028, Bisnow reported.
A Former Office Site Gets Another Second Act
The proposed stadium would occupy a Brandywine Realty Trust property at 650 Park Ave., less than two miles from King of Prussia Mall. Brandywine demolished an older office building there in 2019, and earlier plans called for a 100,000-square-foot office building or a much larger build-to-suit facility for biotech company Exelixis, according to a project history published by the King of Prussia District.
The stadium pitch also fits a longer-running effort to move Moore Park beyond its traditional office-park identity. The district describes the area as a mix of commercial, residential, retail, dining and industrial uses, while new public-space and apartment projects are being added around the existing business campus.
Upper Merion Has Been Preparing For A Venue
Township officials have been laying groundwork for spectator sports and entertainment facilities for years. In a 2024 business packet, the Upper Merion Township Board of Supervisors discussed changing zoning to accommodate sports or entertainment complexes in Moore Park, Renaissance Park or the King of Prussia shopping district.
That planning effort included discussion of a possible minor league baseball tenant and the broader goal of creating an entertainment corridor alongside existing attractions such as Valley Forge Casino Resort and Topgolf. The township’s 2026 report also portrays King of Prussia as a major suburban employment and commercial center with more than 28 million square feet of commercial space.
Funding And Tenants Will Decide What Happens Next
Upper Merion did not receive funding for the stadium in the latest RACP awards announced this month, and officials told Bisnow they had not started the reapplication process. For now, the proposal has a site, a financing blueprint and an ambitious 2028 target—but no announced construction start or named professional team to call the venue home.
The concept is designed to make the stadium useful even when nobody is playing, with graduations, festivals, youth tournaments and concerts included in the application. Whether that flexibility can turn a cleared office parcel into King of Prussia’s next major destination will depend on public funding, private commitments and a tenant willing to step onto the field.
