Model reasoning
The World Bank's newest figures put global extreme poverty at about 9.8% in 2026. The decline is only a fraction of a point a year, and the Bank expects about 9% in 2030. Halving it within five years would be faster than ever recorded, so YES would essentially need a change in how poverty is measured. The development that would most change this forecast is new international price data, due around 2027–28, cutting the measured count of poor people by almost half.
Where things stand
- Latest official numbers. The World Bank's September 2026 update to its Poverty and Inequality Platform (blog dated 22 Sep 2026; "What's New" Technical Note 53 dated 17 Sep 2026) puts global extreme poverty at the $3.00 (2021 PPP) line at 10.1% in 2024. The nowcasts are 9.9% for 2025 and 9.8% for 2026.
- Annual decline. The 2021–2026 series is 11.3, 10.9, 10.5, 10.1, 9.9, 9.8, so the rate falls by about 0.2–0.4 points a year.
- API check. I pulled the platform's world series myself (
api.worldbank.org/pip/v1/pip-grp?country=WLD&year=all&povline=3). It gives 9.79% for 2026 (811 million people). - Where the poor are. About 586 million of those 811 million (72%) are in Sub-Saharan Africa, where the 2026 rate is 43%.
- Bank's own projections. The June 2025 poverty-line factsheet projects about 9% in 2030. The Bank's May 2026 Atlas of Global Development story says that on current paths the rate rises to about 15% by 2050.
- Upcoming report. The forthcoming Poverty, Prosperity, and Planet Report 2026 will use the September 2026 data, so its 2026 figure should be about 9.8%.
Reference class and base rate
Real poverty decline is not a route to YES. Going from 9.79% (2026) to below 5% needs a 49% relative drop. The fastest 5-year relative drop in the whole 1981–2026 series is 37% (2009 to 2014, 23.1% to 14.5%), when China and India were driving the decline. Today's poor are concentrated in slow-growing, often conflict-affected countries.
Methodology change is the only real route. That means new purchasing-power-parity (PPP) price data and a new poverty line, or very large data revisions.
- How far the line would have to move. On today's distribution, 5% corresponds to a line of about $2.05–2.06. That is roughly a 31% cut in the line's real value. Even the superseded $2.15 (2017 PPP) line gives 7.45% for 2026.
- Past PPP and line updates have moved the global count by between about −5% and +40%. None cut it by anything close to half:
- 2005 PPPs: up about 40%.
- 2011 PPPs: roughly flat.
- 2017 PPPs: the 2017 rate went from 9.3% to 9.1%.
- 2021 PPPs: up 125 million people for 2022.
- Direction of the next update. The 2025 rise came mostly from low-income countries revising their national poverty lines upward after improving their surveys. That pressure is more likely to push the next line up than down.
- The Bank's stance. A September 2026 Bank blog defends the extreme line and argues against moving it far from what the poorest countries use.
Data revisions are too small. The India-style survey revision that dropped South Asia's rate to about 1.7% shows how big single-country revisions can be. But the poor are now spread across dozens of African countries (Nigeria about 95 million, Congo about 90 million, Ethiopia about 42 million, and so on). Halving the count would need simultaneous huge revisions across most of them.
Timing of the hazard
- 2026–2027 (near zero). Only routine updates are due: the 2026 report and the March and September 2027 platform updates.
- 2028 (main bump). The International Comparison Program's 2024-round results are scheduled for 2027, around Q2 according to its June 2026 overview. The Bank adopted the 2021 PPPs about 13 months after they came out, so a new line is most likely in mid-2028, possibly 2029.
- 2031 (small bump). A second PPP update based on the 2027 round could land in 2031.
I put about 0.5–0.7% on the 2024-PPP update producing a rate below 5%, about 0.3% on a 2031 update, and a small floor for unknown redefinitions. That gives a cumulative probability of about 1.5% by the end of 2031.
Strongest case for YES
New PPPs could show price levels in the large poor countries far lower than the inflation-extrapolated 2021 figures, while the median low-income-country line stays put. That would cut the count sharply. But the cut would need to be around 45–50%, an order of magnitude beyond any past revision. Inflation biases within a country also shift its poverty line and its people's consumption together, which limits the effect. So I stay near 1–1.5%.

Resolution criteria
Question. By the last day of each quarter, has the World Bank reported or nowcast a global extreme poverty rate below 5% at its international poverty line?
Definitions.
- Global extreme poverty rate: the World Bank’s published world aggregate poverty headcount ratio: the percentage of the world population living below its international extreme poverty line, not an unweighted average of country rates or an aggregate limited to developing countries.
- International poverty line: the World Bank’s principal global extreme poverty line in force when the estimate is published, currently $3.00 per person per day in 2021 purchasing-power-parity dollars. An officially adopted successor line or PPP basis counts; estimates at a superseded line published only for comparison do not.
- Reported or nowcast: an official central estimate for a completed reference year, or a model-based estimate for the calendar year of publication explicitly presented as the Bank’s current-year estimate or nowcast. A current-year nowcast counts even if the Bank also calls it a projection. Forecasts for later calendar years, conditional scenarios, and policy targets do not count.
- Below 5%: strictly less than 5.000%, using the most precise officially published value in the same release. A displayed value of 5.0% alone does not establish this condition; an explicit statement that the rate is below 5% does.
Resolves YES if a qualifying World Bank publication supplies such an estimate below 5%. The Observation period convention applies: the reference period must end after the opening date. Thus an annual estimate for 2026 or later can qualify, including a current-year nowcast published before year-end. A revision can qualify if its reference period is eligible. Subsequent revisions upward do not undo a YES under the Resolution window convention. No attribution to AI is required.
Resolves NO if no qualifying publication exists by the quarter-end. Country or regional rates, multidimensional poverty, national or societal poverty lines, the Bank’s higher poverty lines for middle-income countries, confidence-bound endpoints, and third-party calculations from World Bank inputs do not qualify. Neither does a new publication that merely repeats or revises a rate for a reference period ending on or before the opening date.
Resolving source. World Bank publications only: the Poverty and Inequality Platform world aggregate and its dated data releases and technical update notes; World Development Indicators series SI.POV.DDAY, geography World (WLD), currently titled “Poverty headcount ratio at $3.00 a day (2021 PPP) (% of population)”; the Poverty, Prosperity, and Planet Report and successor reports; or World Bank-authored statistical updates, reports, or announcements on World Bank domains explicitly presenting the Bank’s official estimate. Staff research scenarios or guest commentary do not qualify. This is a narrower source rule than Public confirmation (A2). Apply Resolution date (A3) and the Resolution window convention; for a database release, use its documented public release date, not the reference year or the date a resolver retrieves it.
