**The Tropical Forest Forever Facility (TFFF) is a blended-finance mechanism launched at COP30 in late 2025 to channel sovereign and philanthropic “sponsor capital” into investments whose returns would fund performance-based payments to tropical forest countries that keep deforestation below 0.5 % annually, measured via satellite monitoring.** As of September–October 2026, committed sponsor capital stands at roughly $7.3 billion against the $10 billion threshold needed by 31 December 2026. Pledges from Norway (up to ~$3 billion), Brazil ($1 billion), Indonesia ($1 billion), Germany (€1 billion), France (~€500 million), the UK (~$540 million), and smaller contributors have not accelerated in the final quarter. Geopolitical tensions, domestic budget constraints in key donor nations, and uncertainty over additional large contributors such as China have slowed momentum. With only weeks remaining and no major new announcements on the immediate horizon, traders see limited realistic pathways to close the gap before year-end, producing the current 80.5 % implied probability for “No.” COP31 later in November offers one last diplomatic window, yet current conditions and the recent plateau in pledges support the market’s assessment that the $10 billion mark will not be reached in 2026.
