Spain’s snap general election on November 29, triggered by the collapse of housing decrees amid nationwide protests over rents and evictions, has heightened voter attention and produced early turnout estimates near 74 percent. This level would exceed the 70.4 percent recorded in 2023 and mark the highest participation since 2004, supported by a larger electoral roll of 38.7 million, including 1.6 million first-time voters and expanded overseas participation. Trader pricing remains tightly clustered around the 66–70 percent bands because the housing-driven mobilization must be sustained through six weeks of campaigning, while countervailing factors such as regional variations, weather on polling day, and differential turnout between left- and right-leaning blocs could still compress or elevate final participation. Historical precedent and recent polling averages inform the current distribution but leave room for late shifts.
