Spain's state holds shares worth around €50 billion. Seven of the ten listed companies belong to the Ibex 35. The election could change Madrid's role in strategic businesses.
On 29 November, Spanish voters will decide more than the next government. Pedro Sánchez has called an early general election, and the state remains a major shareholder in ten quoted businesses. Seven are members of the Ibex 35. The Government of Spain has formally confirmed the vote.
The combined market capitalisation of those companies exceeds €342.5 billion. Their state-held shares are worth around €50 billion. Energy, defence, transport and banking are all involved.
That is a large stake.
Control is not spread evenly. The state has decisive voting power in Aena and a major position in CaixaBank. Its influence is also substantial at Indra, Redeia, Enagás and Telefónica. Smaller holdings give Madrid less say over board decisions at other companies.
The official electoral calendar sets 13 November as the start of the campaign and 23 December as the date for the first sitting of the new Parliament.
Aena is the largest asset. Enaire owns 51% of the airport operator. Aena shares closed at €25.84, putting its market value at around €38.8 billion.
The public stake was therefore worth approximately €19.768 billion. That equals about 40% of the state's total portfolio in listed companies. The holding also produced €834 million in dividends from 2025 results.
The government can decide who leads Aena.
CaixaBank comes next. BFA Tenedores holds 18.1%, and the stake was valued at €15.606 billion based on a closing share price of €12.36.
BFA Tenedores was previously wholly owned by the Frob. After the transformation approved by the Council of Ministers in late July, it will become a company attached directly to the Ministry of Economy. Its role in exercising shareholder rights will not change.
The dissolution of both chambers is grounded in Article 115 of the Spanish Constitution and Article 42.1 of the Organic Law on the Electoral Regime. The royal decree also sets the allocation of seats among constituencies, providing the legal framework for the new Congress.
The state is still formally required to sell its CaixaBank holding by December 2027. That deadline has been postponed several times. The latest extension came in February 2025. The government cited more efficient use of public resources and the possibility of recovering more of the money invested.
Sepi manages most of the remaining positions. Its largest is a 4.12% stake in Airbus, worth more than €6.1 billion at a share price of €188.
Indra follows. Sepi owns 28% after the government bought an additional 10% in 2022 for nearly €174 million. The package is now worth about €1.05 billion, roughly €880 million more than its purchase price.
Telefónica tells a different story. The state returned to the company's capital after almost three decades outside it. It paid around €2.285 billion for 10%.
The stake is now valued at €1.917 billion. Share performance cut its value by €368 million. The purchase followed the unexpected entry of Saudi company STC. It later proved decisive in Marc Murtra's arrival at the presidency.
Energy and transport give the state more leverage. Madrid owns 20% of Redeia, worth close to €1.6 billion, and is the company's largest shareholder.
Sepi also holds 5% of Enagás, valued at around €200 million. It remains the company's principal shareholder despite the smaller stake. In transport, the state controls 2.52% of IAG, worth about €600 million, and 7.8% of Talgo after investing €75 million last year.
The Talgo holding is now worth around €25 million.
The portfolio includes 10.36% of Ebro Foods, valued at €289 million. State influence is strongest where its stake provides control or makes it the leading shareholder. Aena, Redeia, Enagás and Indra are clear examples.
At CaixaBank, Ebro Foods, Talgo, Airbus and IAG, the public presence has less weight in governance.
Since Sánchez entered the government, Madrid has returned to Telefónica, increased its position in Indra and entered Talgo. The election could decide whether the state expands or reduces its listed-company portfolio.
It could also decide how those holdings are used. They may remain financial assets, or become tools of influence in strategic sectors. The largest stakes sit in infrastructure and finance. The €50 billion package gives the next government a clear measure of economic direction.
Sánchez said he made the decision after notifying the head of state and holding an extraordinary meeting of the Council of Ministers. He presented the vote as a chance to determine the country's future political course.
