Analysis
This probability reflects the chance that UK Prime Minister Keir Starmer becomes NATO's next Secretary General, currently trading at 9% on prediction markets. NATO Secretary General positions typically go to senior figures with strong diplomatic credentials and support from member states, with the next scheduled election occurring in 2026. Starmer's relatively low probability reflects that other European political leaders—particularly Kaja Kallas, Ben Wallace, and Alexander Stubb—are viewed as more likely candidates by traders. The position requires consensus among NATO members, and UK domestic political constraints may limit Starmer's viability. Key drivers would be changes in NATO member preferences, developments in European geopolitics, or unexpected withdrawals by frontrunner candidates that shift the selection dynamics.
- ›Kaja Kallas is trading at 6¢ across multiple contracts—significantly higher than Starmer at 9¢—suggesting markets view other European leaders as stronger candidates for the role
- ›NATO Secretary General elections require broad consensus among 32 member states; a sitting UK Prime Minister managing domestic governance may face practical constraints as a candidate
- ›Ben Wallace (6¢) and other defense-focused European figures have more recent institutional experience with NATO structures than Starmer
- ›The Secretary General election timing and any official announcements from current leadership or prospective candidates would provide material new information to resolve uncertainty
- ›Starmer's probability could shift substantially if frontrunner candidates withdraw or if UK-NATO relations become a dominant political factor reshaping member preferences

Russia Advancing on Donbas — Kostyantynivka Capture by June at 62%
Prediction markets price Kostyantynivka capture by June 2026 at 62%, reflecting expectations of sustained Russian Donbas momentum and minimal ceasefire prospects through 2026.
Ukraine Ceasefire Odds Sink: December Target Loses 4 Cents
The probability of a Russia-Ukraine ceasefire by December 31 fell 4 cents to 47%, while the 'peace deal before 2027' contract edged up 1 cent to 29%. This divergence suggests traders see a ceasefire as less likely near-term, but are not giving up on a longer-term peace process. Russia's capture of key towns is also being priced.
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.
