Alpha Opportunity
Alpha Thesis
Our AI estimates a true probability of 15.0% vs the market's 49.5%, identifying a 34.5% edge on the NO side. Historically, the probability of any specific four teams reaching the semifinals is low due to the competitive nature of the World Cup. The base rate for any specific team reaching the semifinals is approximately 25% based on historical data. France, Spain, England, and Argentina are all strong teams with a history of performing well in international tournaments. However, the current tournament data shows that while Spain and France have advanced to the semifinals, England and Argentina are still in contention but not confirmed.
📐Key Metrics
Key Findings
- Historical Semifinal Appearances — Historically, the probability of any specific four teams reaching the semifinals is low due to the competitive nature of the World Cup. The base rate for any specific team reaching the semifinals is approximately 25% based on historical data.
- Current Tournament Performance — France, Spain, England, and Argentina are all strong teams with a history of performing well in international tournaments. However, the current tournament data shows that while Spain and France have advanced to the semifinals, England and Argentina are still in contention but not confirmed.
- Probability of Each Team Reaching Semifinals — Assuming each team has a 25% chance of reaching the semifinals independently, the combined probability of all four teams reaching the semifinals is 0.25^4 = 0.0039 or 0.39%. Adjusting for current performance, this probability increases but remains low.
- Updating with Current Evidence — Starting with a low base rate, the current evidence of Spain and France's advancement increases the probability slightly, but the uncertainty around England and Argentina's advancement keeps the overall probability low.
- Resolution Criteria — The market resolves to 'Yes' if the semifinals are FRA vs ESP and ENG vs ARG. It resolves to 'No' if any of the teams are mathematically eliminated from reaching the semifinals. If the World Cup is canceled or semifinals matchups are not declared by August 2, 2026, 11:59 PM ET, it resolves to 'Other'.
