26% — Will Arsenal qualify for the Champions League Semifinals Kalshi 26% · 14 contracts · $259 volume · medium confidence Updated 2026-09-25 10:43:43 UTC Why this matters: This 39% probability reflects the market's assessment that Arsenal will advance past the Champions League quarterfinals to reach the semifinals. The prediction sits roughly in line with other top-tier clubs, suggesting modest confidence in their progression. Arsenal's qualification odds depend primarily on their opponent draw, current squad depth compared to other elite European sides, and their performance in knockout matches where fine margins determine advancement. The UEFA Champions League round-of-16 draw and subsequent fixture scheduling will be the key event that clarifies Arsenal's path—stronger opponents significantly lower progression chances, while favorable matchups could shift the probability notably higher. Historical knockout-stage performance, injury status of key players heading into spring fixtures, and their domestic league position affecting overall squad fatigue will all influence final outcomes. Key factors: - Arsenal's opponent in the round-of-16 draw will materially affect their semifinal odds, with top-seeded teams like Real Madrid or PSG creating steeper paths than other qualified teams - Head-to-head record and tactical matchups against potential opponents carry predictive value for knockout-stage advancement beyond general team strength rankings - Squad injury status and player availability during the critical February-May Champions League period, particularly in defense and attack, directly impacts match outcomes - Arsenal's domestic league performance and fixture congestion in concurrent Premier League matches can affect rest and form entering knockout stages - Historical penalty shootout record and clutch performance metrics in previous knockout rounds provide evidence of how teams handle elimination-stage pressure Contracts: - Will Barcelona qualify for the Champions League Final?: Barcelona — 31¢ Kalshi $121 (weight 47%) - Will PSG qualify for the Champions League Round of 16?: PSG — 56¢ Kalshi $59 (weight 23%) - Will Arsenal qualify for the Champions League Final?: Arsenal — 27¢ Kalshi $50 (weight 19%) - Will Manchester City qualify for the Champions League Final?: Manchester City — 22¢ Kalshi $13 (weight 5%) - Will PSG qualify for the Champions League Semifinals?: PSG — 40¢ Kalshi $10 (weight 4%) - Will Real Madrid qualify for the Champions League Semifinals?: Real Madrid — 34¢ Kalshi $5 (weight 2%) - Will Barcelona qualify for the Champions League Semifinals?: Barcelona — 39¢ Kalshi $0 (weight 0%) - Will Bayern Munich qualify for the Champions League Final?: Bayern Munich — 28¢ Kalshi $0 (weight 0%) - ... and 6 more --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question.
