Pope Leo XIV's visit to Spain, estimated at 25 million euros, is significantly funded by private entities, benefiting from substantial tax deductions as it has been declared an "event of exceptional public interest." Nationally, 48 companies and foundations are contributing around 12 million euros, in addition to anonymous donations from major benefactors who receive exclusive perks.

In the Canary Islands, the Canarian Employers' Confederation (CCE) has confirmed financial support from over forty local companies for the logistical arrangements of the papal journey to Gran Canaria. These donations, averaging around 3,000 euros per company according to CCE sources, exceed 120,000 euros. These are complemented by monetary contributions from citizens, totaling 175,000 euros, as reported by the Diocese of Canarias.

In-kind donations are also substantial, ranging from telecommunications equipment and software to supplies for volunteers and event participants. For the event in Arguineguín, several firms have assisted in preparing 2,500 backpacks with water, caps, nuts, and juice, and 10,000 bottles of water are to be distributed to accredited attendees.

Canarian public institutions are also major funders of the event. The Government of the Canary Islands has announced a contribution of 2 million euros, while the Cabildo of Gran Canaria and the Cabildo of Tenerife are each contributing half a million euros. The Catholic Church has assured that all donations will be audited and accounted for upon the event's conclusion, managing funds responsibly and transparently through the official trip website.
