Born in Azkoitia, Gipuzkoa, Basque Country, Zubeldia joined Real Sociedad’s youth setup in 2008, at the age of 11. On 6 June 2015, he promoted to the reserve team in Segunda División B.
Zubeldia made his senior debut on 29 August 2015, coming on as a second-half substitute in a 0–1 away loss against CD Ebro. On 25 February of the following year, he renewed his contract with Sanse until 2021.
Zubeldia made his first team – and La Liga – debut on 13 May 2016, replacing fellow youth graduate Rubén Pardo in the dying minutes of a 1–0 away win over Valencia CF. Ahead of the 2017–18 season, he was definitely promoted to the main squad.
On 20 December 2017, after just 30 seconds on the pitch, Zubeldia scored his first goal in the Spanish top flight to put the hosts ahead in the 76th minute of an eventual 3–1 home defeat of Sevilla FC. The following 29 June, he renewed his contract until 2024.
