# Gates and Buffett launch the Giving Pledge

Date: 2010

## The fact

In 2010 [Bill Gates](/people/bill-gates) and Warren Buffett launched the Giving Pledge, inviting billionaires to commit a majority of wealth to philanthropy.

## Context

Neighbouring foundation is the Gates vehicle. Neighbouring Zuckerberg and Bezos later signed as different people. He did not write a wealth-tax statute.

Foundation 2000 is neighbouring. 2008 full-time shift is neighbouring calendar.

Bill Gates was Microsoft CEO until January 2000, chairman until February 2014, then a technical adviser until 2020, and a Gates Foundation co-chair. That is not authorship of every Windows copy, every GAVI dose, or every IRS schedule. Melinda French Gates is a different person. Bill Clinton is PER-000772, a different person. A pledge is not a coverage rate. A docket is not a personality.

## Evidence and sources

Giving Pledge carries the official instrument or communique. Reuters records the same dated act independently.

## Significance

The path is [income-inequality](/drivers/income-inequality) mixed: a completed pledge campaign is an attempted private redistribution instrument that also concentrates agenda power in foundations.

## What is established and what is not

Established: 2010 Giving Pledge launch, independently reported.

Not established: that inequality fell that year, or a unique later tax-revenue coefficient from a letter.

What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Signatories pledged. Buffett is a different person.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Gates and Buffett launch the Giving Pledge, not a later speech about Gates and Buffett launch the Giving Pledge.

Co-authors and later implementers named in Context remain on the file. Gates and Buffett launch the Giving Pledge on 2010-08-04 is not a licence to treat every later Giving Pledge communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average Gates and Buffett launch the Giving Pledge into a personality. The contribution described on this Person row is limited to He co-launched with Buffett. Signatories pledged. Buffett is a different person. That limit is the alternative to treating office-holding as authorship of every later series.
