Today marks the 10th anniversary of Giving What We Can, a community of people who have pledged to donate at least 10% of their income to the most cost-effective charities. During these ten years, 4,343 members have collectively donated $126,751,939.
This question asks: How many members will Giving What We Can have at the end of the day of its 20th anniversary (November 15, 2029)?
The question resolves according to official GWWC figures. If the organization ceases to exist in the meantime, the question resolves ambiguous.
