PBSScore Breakdown

D
21.9
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
No data

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

No giving data on file. That is a gap in our sources, not a finding that this person gives nothing — and because the component still counts as zero, it holds this score down. Know of a gift we are missing? Tell us and we will source it.

Transparency35% weight
63%

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 8/31/2026 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.
