Sixteen Thirty is a high-volume funding hub with Arabella administration, NVF payroll integration and reciprocal grant flows

Sixteen Thirty Fund can now be mapped as a high-volume national 501(c)(4) grantmaking and operational-support hub with several layers that require separate analysis. Its FY2024 Form 990 reports $282.24M total revenue, including $275.16M in contributions, $310.78M expenses, $236.50M in grants and similar amounts paid, and $88.41M year-end net assets. IRS-derived 2019-2025 grant records identify at least $497M in itemized institutional grants to Sixteen Thirty from 84 funders, led by New Venture Fund (~$234.8M), Open Society Policy Center (~$68.2M), Catalyst4 (~$36.0M), Future Forward USA Action (~$29.2M), North Fund (~$24.7M), Hopewell Fund (~$22.5M), and Democracy Fund Voice (~$14.4M). Separately, IRS-derived 2020-2024 data show Sixteen Thirty awarded about $923.6M across 1,345 grants to 749 organizations, including America Votes (~$179.6M), North Fund (~$40.5M), League of Conservation Voters (~$40.2M), Western Futures Fund (~$5.1M), New Venture Fund (~$9.6M), and many others. This creates notable reciprocal grant relationships: New Venture Fund gave Sixteen Thirty about $234.8M while Sixteen Thirty separately gave New Venture about $9.6M; Sixteen Thirty gave North Fund about $40.5M while North Fund separately gave Sixteen Thirty about $24.7M. These reciprocal grant flows are real organizational transactions but do NOT by themselves establish circular laundering, same-dollar recycling, illegality, or improper purpose; each grant must be audited by year, stated purpose, restrictions, and project. Sixteen Thirty’s own FY2024 Schedule O adds an important administrative layer: it states that Arabella Advisors provides business/administrative services including regulatory compliance, HR, payroll and other functions, and that New Venture Fund—described expressly as an unaffiliated 501(c)(3)—serves as a payroll reporting agent for Sixteen Thirty under IRS common-paymaster rules, with Sixteen Thirty reimbursing NVF for allocated employee salaries and benefits. The filing also reports $6.63M paid to Arabella Advisors for support services. This establishes documented administrative/payroll integration among Sixteen Thirty, Arabella and New Venture alongside large inter-organizational grant flows. The next audit should decompose every major upstream and downstream transfer by year, amount, legal entity, grant purpose, restricted project and ultimate Idaho-relevant route rather than treating Sixteen Thirty as an opaque terminal node.
