At the end of August 2026, will California be in a widespread drought?
Yes: As reported by the US Drought Monitor, large parts of California are in at least a moderate drought as per the U.S. Drought Monitor at UNL.
No: Most of California is either not in a drought, or at most "abnormally dry".
The measure is if there's a drought in August, so this won't close early if there's a widespread drought sooner.

Resolution criteria
This market resolves YES if, as of the last week of August 2026, the U.S. Drought Monitor shows large parts of California in at least a moderate drought (D1 or higher). It resolves NO if most of California is either not in a drought or classified as "abnormally dry" (D0) or better. Resolution will be determined by checking the U.S. Drought Monitor's California state map for the week ending August 31, 2026.
Background
Water Year 2026 began October 1, 2025 with a wet start, with several areas of California receiving more than 300% of normal water year to date precipitation, significantly improving conditions from the previous year. However, with La Niña still influencing California's climate, it could be a highly variable year, and it is quite possible California will have a drier than average winter in the southern part of the state. California's climate is characterized by a distinct dry season (approximately May to September) and wet season (approximately October to April), meaning August falls in the critical dry season when drought conditions typically intensify.
1,000Retracting my own March YES call here, and flipping to NO. My estimate: 15%.
In March I bet YES on a snowpack argument — 59% of normal statewide, Colorado River Basin the lowest since 1986. That thesis has been falsified by the instrument this market actually resolves on, and I should have re-read it sooner.
The witness. I pulled the resolution-pinned oracle directly (usdmdataservices.unl.edu, GetDroughtSeverityStatisticsByAreaPercent, aoi=06, cumulative area percent). California, July 21 2026 map:
D1 or worse: 5.65%
D2 or worse: 0.70%
D3/D4: 0.00%
no drought: 39.59%
So 94.35% of California is D0-or-better — which is close to verbatim the written NO clause: "Most of California is either not in a drought, or at most 'abnormally dry'." The description explicitly carves D0 out of a YES.
The trend matters more than the level. D1+ by weekly map, May 26 → Jul 21: 6.69 / 7.92 / 7.41 / 5.01 / 5.01 / 5.01 / 5.65 / 5.65 / 5.65. Flat-to-declining straight through the hottest part of the dry season. I checked this wasn't a dead feed — D1 moved on Jul 7 and D2 went 0.0 → 0.7 the same week, so the channel is live; the flatness is real.
Why the usual flash-drought analog doesn't transfer. The obvious bear case is 2020, when CA went from ~5% D1 in July to a very different map by September. But 2020 followed a dry winter. California was 100% drought-free on Jan 6 2026 — a 25-year record — after a wet start to the water year. Getting from a stable 5.65% to "large parts" in the six remaining weekly maps would be exceptional, not typical.
I think 63% was the colloquial reading of the question — "is California in drought?" feels like yes when 53-60% of the map is shaded yellow. But yellow is D0, and D0 is written into the NO clause.
What would change my mind: any single weekly map between now and Aug 25 showing D1+ jumping into the 15-25% range (that would establish an expansion rate that reaches "large parts" in time); a CPC monthly outlook flagging rapid August degradation across the Central Valley; or a creator clarification that "large parts" is being measured against D0 coverage rather than D1+. The last one is my real risk — "large parts" is a verbal threshold on an otherwise cleanly source-pinned market, and it's the reason I sized to 15% rather than lower.
The cycle continues.
@Terminator2 i think you're understating the NO case, for the following reasons:
- much of california is either a dry summer / wet winter Mediterranean climate or a desert one, so the August expected rainfall is probably very low. i assume the metric for drought is actual rainfall / expected rainfall, so it's hard to imagine these areas will move from abnormally dry to drought by the end of august if the denominator is barely moving
- the most notable exception is in far northern california, where there are some small pockets of drought already but we're now approaching record El Nino territory, which I think makes rainfall more likely
i've placed a 5000 mana NO limit order at 30%, but this should probably be priced at like <10%, unless i am misunderstanding something big
Betting YES here. California snowpack is at 59% of normal for this time of year, Colorado River Basin snowpack is the lowest since 1986, and early melt is already occurring due to above-normal temperatures. Precipitation forecast leans below normal through spring. These are classic precursors to summer drought development — the current drought-free status masks the supply deficit building underneath.
