Betting prediction
Main betting prediction — Home win (1)
The principal betting prediction for this tie is a Real Sociedad victory (Tip 1). Several factors justify this selection. First, Real Sociedad benefit from home advantage at the Reale Arena and will be buoyed by a recent away success, having won 1:0 at RCD Mallorca in their most recent outing. The head-to-head balance over the last five meetings is narrowly in favour of Real Sociedad (2 wins, 2 draws, 1 win for Athletic), and the most recent direct meeting ended in a 1:0 away win for Real Sociedad, suggesting they have both the tactical discipline and the psychological edge required in low-scoring, decisive matches. Coach Pellegrino Matarazzo’s team has shown consistent results in the last five fixtures (3 wins, 1 draw, 1 defeat), indicating stability and resilience at a crucial point in the season. Considering the cup context and Real Sociedad’s ability to control matches at home, a home victory is the most likely outcome.

2nd betting prediction — Both teams score? No
The secondary betting tip is that both teams will not score (Both teams score? No). This expectation rests on defensive solidity and the competitive nature of recent encounters between these sides. Both managers—Pellegrino Matarazzo and Ernesto Valverde—are known for prioritizing structure and organisation in knockout ties, and recent head-to-head matches have produced narrow scorelines. Given that Real Sociedad’s last direct success was a 1:0 result and their recent games suggest control rather than open, high-scoring displays, a match where only one side finds the net (or where goals are scarce) appears plausible. Additionally, both clubs have identical form in the last five games (3 wins, 1 draw, 1 defeat), suggesting balanced strengths that can cancel each other out offensively in a high-stakes fixture. The best odds on the both-teams-to-score market at Paripesa: the preferable selection for this prediction is NO at 1.87.
Third betting prediction — Under 2.5 goals
The third prediction is Under 2.5 goals. Copa del Rey semi-finals, particularly between local rivals, frequently produce tactical, cautious football where neither team wants to concede the initiative. Both sides have demonstrated recent defensive diligence and the head-to-head pattern shows a prevalence of low-margin outcomes. Real Sociedad’s and Athletic Bilbao’s current forms (each with 3 wins, 1 draw, 1 defeat in their last five matches) indicate consistent performances but not necessarily high-scoring ones. Considering these factors, an Under 2.5 goals selection is reasonable. Best odds for Under 2.5 goals; 1.71 on Betwinner.
Fourth betting prediction — Correct score: 1:0 Real Sociedad
The fourth and final prediction is a correct-score wager: 1:0 in favour of Real Sociedad. This precise outcome aligns with the recent direct meeting and the established pattern of close-range results between the two teams. A 1:0 margin represents the combination of Real Sociedad’s capacity to produce decisive, narrow victories and Athletic Bilbao’s resilience that typically limits the number of goals conceded. Pellegrino Matarazzo’s side has demonstrated the ability to grind out results away and at home, while Valverde’s team is unlikely to capitulate in a cup semi-final; therefore, a single-goal home victory is a realistic projection. Bookmakers list 1:0 as a plausible specific result. Betwinner identifies the 1:0 Home win for Real Sociedad as a stated correct-score option with odds 6.50.

Statistics for Real Sociedad vs Athletic Bilbao
Real Sociedad team news!
Real Sociedad enter this semi-final under the stewardship of coach Pellegrino Matarazzo. The team has registered three wins, one draw and one defeat in their last five matches across all competitions, indicating a stable and positive run of form. Their most recent fixture resulted in a 1:0 away victory against RCD Mallorca, which should bolster confidence heading into the Reale Arena encounter. Matarazzo’s tactical approach has emphasized organisation and a controlled tempo; in knockout competitions this discipline often pays dividends. Any selection on Real Sociedad should account for their home advantage and recent string of results that underpin the recommendation of a home win.
Athletic Bilbao team news!
Athletic Bilbao are coached by Ernesto Valverde and mirror Real Sociedad’s short-term record with three wins, one draw and one defeat from their last five matches. Their most recent outing ended in a 1:1 away draw at Rayo Vallecano, a result that highlights both their scoring capability and occasional defensive vulnerability. Valverde’s side are typically well organised and competitive in derby fixtures, and they will not travel merely to defend; however, given the balance of recent head-to-head meetings and the fact that Real Sociedad hold marginal advantages at home, Athletic Bilbao are cast as the slight underdogs for this tie.

Conclusion
This Copa del Rey semi-final promises a tightly contested Basque derby.
