Analysis
The SPD currently has an 19% chance of winning the 2026 Hannover mayoral election, meaning markets assess it as an unlikely but possible outcome. The probability reflects that the Green Party leads at 46%, with SPD second at 36%, while smaller parties (Die Linke, AfD, CDU) trail significantly. SPD's position depends on whether it can consolidate left-leaning and centrist voters, or whether it loses support to Greens or coalition dynamics shift. The outcome will be determined by the October 2026 election itself, but candidate announcements, local campaign visibility, and polling data in the months preceding the vote could shift expectations. Current low trading volume across contracts suggests limited market activity and potential for price movement as the election approaches and more information becomes available.
- ›Green Party holds 46% implied probability versus SPD's 36%, indicating markets currently favor Greens as frontrunner
- ›SPD and Greens together represent 82% of total implied probability, suggesting the race is concentrated between two parties
- ›Trading volume across all five contracts is low (under $10 combined daily volume), indicating thin markets susceptible to repricing
- ›Die Linke, AfD, and CDU each under 6% suggests fragmentation among right-wing and far-left alternatives
- ›October 2026 election date is the single resolution catalyst; interim data from candidate nominations, rallies, or regional polling could move prices significantly before then

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
