Public Benefit Score
The PBS is a weighted average of 2 components. The formula is open and versioned — the weight percentages below show how much each component contributes to the final score.
Philanthropy65% weight
Evidenced charitable giving — built on what they actually give each year, not parked assets. Dominated by generosity (annual giving relative to net worth — the share of your fortune you give), plus the absolute scale of that giving, plus a small nudge for signing the Giving Pledge (a commitment, not a realized action).
Data: ProPublica 990 charitable disbursements, net worth, The Giving Pledge registry
Transparency35% weight
How much sourced, public accountability data exists — net worth, political contributions, SEC filings, foundation 990s, news coverage, and a verified profile. More public disclosure scores higher.
Data: FEC, SEC EDGAR, ProPublica 990s, GDELT / NewsAPI, Wikidata
Formula (v2): PBS = 65% x Philanthropy + 35% x Transparency
Scored on 6/23/2026 on a 0–100 scale. The score uses only the signals we have populated data for. Goal Impact, Controversy, and Community Approval are deferred until that data exists — Phase 1 goal adoption, controversy detection, and community votes respectively.
