The Waiting Room

Make a probability forecast before you see the outcome. Your estimates stay on this device unless you export them.

15 source-linked forecasts await resolution. The archive is a dated snapshot. Outcomes are resolved by an editorial evidence check, not automatically when a clock runs out. Anonymous visitor averages are shown when submissions exist. Sharing is optional; the saved forecast remains on this device. Account sync is not enabled.

Over 40% of agentic AI projects will have been cancelled by the end of 2027.

Gartner · Made 2025-06-25

Resolution criteria

Compare the cancelled-project proportion at year-end 2027 with the strict >40% threshold, using Gartner’s original project population and agentic-AI definition. If that denominator is not disclosed, retain an unresolved result rather than infer a population from anecdotes.

Global coal demand will level off near 8.87 billion tonnes in 2027.

International Energy Agency · Made 2024-12-18

Resolution criteria

Compare global calendar-2027 coal demand, across coal grades and uses, with 8.87 billion tonnes and report the signed numerical error. Use the 2024 report’s definitions and current-policy scenario; coal-fired electricity alone is not total coal demand.

Global solar-PV electricity generation will surpass wind generation in 2027.

International Energy Agency · Made 2024-10-09

Resolution criteria

Compare worldwide calendar-2027 solar-PV generation in TWh with total wind generation in TWh; success requires solar PV > wind. Installed capacity alone does not resolve this generation claim.

At least 15% of day-to-day work decisions will be made autonomously through agentic AI by 2028.

Gartner · Made 2025-06-25

Resolution criteria

Test whether the measured share of day-to-day work decisions made autonomously by agentic AI is >=15% by year-end 2028. Preserve Gartner’s decision and autonomy definitions; assisted decisions do not satisfy an autonomous-decision claim.

33% of enterprise software applications will include agentic AI by 2028.

Gartner · Made 2025-06-25

Resolution criteria

Record the year-end 2028 proportion of enterprise software applications including agentic AI and its percentage-point difference from 33%. Use the source’s application population and agentic classification; unavailable comparable measurement leaves the claim unresolved.

Worldwide artificial-intelligence spending will exceed US$631 billion by 2028.

International Data Corporation · Made 2024-08-21

Resolution criteria

Compare calendar-2028 worldwide AI spending with the strict US$631-billion threshold, using IDC’s 2024 V2 Spending Guide categories and currency basis. Later methodology changes require a bridge to that scope; a different definition of the AI market does not independently resolve the claim.

10% of global boards will use AI guidance to challenge materially important executive decisions by 2029.

Gartner · Made 2025-06-17

Resolution criteria

Measure the 2029 share of boards actually using AI guidance to challenge material executive decisions and report deviation from 10%. General AI discussion or procurement is insufficient; use a comparable board survey and the source’s materiality definition.

There is a 70% probability that mean global warming over 2025–2029 exceeds 1.5°C above 1850–1900.

World Meteorological Organization / UK Met Office · Made 2025-05-28

Resolution criteria

Compute the average global near-surface temperature anomaly for the five calendar years 2025–2029 against the 1850–1900 baseline; the event occurs only if the five-year average is >1.5°C. Record this as one outcome of a 70% probabilistic forecast, not as a deterministic promise or a long-term Paris-threshold crossing.

Global public debt will reach 100% of global GDP by 2029.

International Monetary Fund · Made 2026-04-15

Resolution criteria

Compare the IMF Fiscal Monitor global gross public-debt-to-GDP aggregate through 2029 with 100%, keeping its country coverage and aggregation convention. Record whether the threshold is reached and the 2029 percentage-point error; net debt or private debt does not resolve this claim.

Electric cars will exceed 40% of worldwide new-car sales in 2030 under the 2025 policy settings.

International Energy Agency · Made 2025-05-14

Resolution criteria

Divide global 2030 battery-electric plus plug-in-hybrid car sales by total new-car sales using IEA categories; test the >40% threshold. Record subsequent policy changes separately because this is a stated-policy conditional projection.

World oil demand will plateau near 105.5 million barrels per day by 2030, with a small decline that year.

International Energy Agency · Made 2025-06-17

Resolution criteria

Compare IEA-defined total liquids demand in calendar 2030 with 105.5 mb/d at 0.1-mb/d precision, and separately test whether 2030 demand is below 2029 demand. The point estimate and directional decline are two explicit parts; do not substitute production capacity.

Resolution criteria

Compare IEA-defined global oil production capacity at the 2030 forecast endpoint with 114.7 mb/d and report numerical error at 0.1-mb/d precision. Capacity includes the report’s liquids categories and is distinct from actual output, demand or refinery throughput.

Current prospects imply 512 million people, about 6% of humanity, will be chronically undernourished in 2030.

FAO, IFAD, UNICEF, WFP and WHO · Made 2025-07-28

Resolution criteria

Compare the FAO prevalence-of-undernourishment model’s 2030 global headcount with 512 million and record error, preserving the 2025 methodology or publishing a revision bridge. This is the current-prospects projection, not the Zero Hunger policy target; food insecurity survey measures are a different outcome.

Your calibration.

A Brier score needs a resolved outcome. Your saved probabilities will appear here when the archive contains a supported binary resolution. No resolved personal forecasts yet.

Brier score = (probability − outcome)², with probability from 0 to 1 and outcome 0 or 1. Lower is better. Calibration groups forecasts by predicted probability and compares that with observed frequency.
