Launched the Reinvent the Toilet Challenge to solve global sanitation
[RECORD.TXT] · cat --full
The Gates Foundation launched the Reinvent the Toilet Challenge, awarding grants to universities to design a self-contained toilet that works without water, sewage, or electricity and costs under $0.05 per user per day. Gates announced the initiative at a press conference by holding a jar of human feces, emphasizing that 2.5 billion people worldwide lacked access to safe sanitation. The challenge produced dozens of working prototypes and drove real investment in next-generation sanitation technology for low-income markets.

Melinda French Gates announced in June 2026 that she would donate an additional $215 million through her organization Pivotal to focus on women's reproductive and midlife health, bringing her total support for women's health to about $600 million over two years. The commitment underscored French Gates's independent philanthropic path since stepping down from the Gates Foundation in 2024 and her focus on areas she has said are chronically underfunded. It came amid broader cuts to U.S. reproductive- and global-health funding.

Bill Gates publishes the 2026 Gates Foundation Annual Letter, 'Reaching 2045'
Bill Gates published the 2026 Gates Foundation Annual Letter, titled 'Reaching 2045,' framing the next two decades as the Foundation spends down its endowment before closing in 2045. Gates wrote that his optimism now 'comes with footnotes,' questioning whether global generosity will keep pace with rising wealth and whether innovation will be scaled to reduce inequality. He pledged to spend much of 2026 advocating for child-health funding and set a goal of again halving child mortality in the global South by 2045, while voicing both excitement about AI for health and concern about managing its disruption.
