Context
The market’s assessment has fluctuated from 11.0% to 16.5% in recent months, with the latest reading at 15.0%. The 24-hour change stands at +0.5 pts. This market resolves to Yes if the governing coalition consisting of CDU/CSU and SPD breaks by December 31, 2026, 11:59 PM CET. A break is defined as either party ceasing to be a coalition partner, which can be evidenced by a formal withdrawal, the resignation or dismissal of all ministers from one party, or the appointment of a new federal government. If all ministers from a party leave, that may signal withdrawal even if some remain as independents. The break date is the official confirmation date; speculation or reports of an impending break do not count. Resolution relies primarily on official German government information, with a consensus of credible reporting as a fallback. The deadline of Dec 31, 2026 means that any political development before that date that meets the formal criteria could shift the probability. Official government announcements and credible news consensus will be the key triggers.
FAQ
What exactly counts as the coalition breaking?
The coalition is considered broken if either the CDU/CSU or SPD ceases to be a coalition partner. This can be triggered by a formal withdrawal, the resignation or dismissal of all ministers from one party, or the appointment of a new federal government. Even if some individuals remain in office as independents, the departure of all party-affiliated ministers may signal the party’s withdrawal.
When does the market resolve?
The market resolves to “Yes” if a break is officially confirmed by December 31, 2026, at 11:59 PM CET. If no such confirmation occurs by that deadline, it resolves to “No.”
What is the primary source for resolution?
The primary source is official information from the German government. However, if that is unclear, a consensus of credible reporting from major reputable news outlets may be used.
Does speculation about a break count?
No. Only the official confirmation date matters. Reports of negotiations, speculation, or indications of an impending break are not sufficient to trigger resolution.
What if the coalition breaks but the Chancellor stays in office?
The market would still resolve to “Yes.” As long as one party leaves the coalition, it counts as a break, even if the Chancellor forms a new coalition or leads a minority government.
