Prolonged drought and extreme heat across Central Europe have driven the Danube to record-low flows in mid-2026, with Budapest gauges near 10–23 cm and mid-August discharge roughly half the long-term average, disrupting navigation, irrigation, and hydropower. Satellite comparisons from August 2025 to 2026 confirm widespread shrinkage along Hungarian and Romanian sections, while forecasts show limited near-term rainfall and renewed high temperatures that slow recharge from Alpine headwaters and tributaries. These conditions explain trader consensus favoring October or late-September normalization, alongside the 20.5% probability of persistence past November 1. Seasonal precipitation patterns and upstream snowmelt timing remain key variables that could accelerate or further delay recovery within the resolution window.

"Does not return by November 1, 2026" resolves "Yes" if no reading at or above 93 centimeters is recorded at the Budapest gauge at any time on or before October 31, 2026 11:59 PM UTC. Readings after this cutoff are not considered, and any return to normal levels occurring on or after November 1, 2026 does not affect resolution.
The resolution is triggered by the first reading at or above 93 centimeters recorded on or after the market's start, representing a rise back to the threshold. A single reading at or above 93 centimeters is sufficient to trigger resolution; transient spikes count, and the water level does not need to be sustained at or above 93 centimeters for any period.
The bracket containing the timestamp of the first reading at or above 93 centimeters resolves "Yes"; all other brackets resolve "No".
The primary resolution source for this market will be DanubeHIS (https://www.danubehis.org/results/HU442027_HYDRO). If DanubeHIS is unavailable, this market may resolve based on a consensus of credible reporting.
