Altenar Extends Partnership with Gran Madrid | Casino Online for Spanish Sportsbook Dominance

Altenar, a leading provider of sportsbook and iGaming software solutions, has renewed its long-term partnership with Gran Madrid | Casino Online, the flagship online betting brand operated by Gran Madrid. The agreement ensures Altenar will continue delivering its award-winning sportsbook technology to the regulated Spanish market, reinforcing its position as a key player in the region.

This extension builds on a successful collaboration, allowing Gran Madrid | Casino Online to leverage Altenar‘s flexible and feature-rich sportsbook platform, tailored specifically to meet the demands of Spanish players. The partnership supports Gran Madrid‘s omni-channel strategy, seamlessly integrating its established retail sportsbook presence across its casino venues with its online offering.

Since the inception of their collaboration, Gran Madrid | Casino Online has enhanced its sportsbook capabilities by combining Altenar‘s advanced technology with its own strong market position in Spain. The operator benefits from Altenar‘s comprehensive market coverage, advanced trading tools, and localized features designed for regulated jurisdictions. These strengths have driven impressive commercial results, with sportsbook turnover surging by 21% year-on-year in the first half of 2026 compared to the same period in 2025.

Antonis Karakousis, Director of Operations at Altenar, expressed his enthusiasm for the renewed partnership, stating, “We are delighted to extend our partnership with Gran Madrid | Casino Online. Over the course of our collaboration, we have built a strong relationship based on trust, performance, and a shared commitment to delivering an outstanding sportsbook experience for Spanish players.”

“Spain remains one of Europe’s most mature regulated markets, and we are proud to continue supporting Gran Madrid | Casino Online with a sportsbook solution that combines flexibility, reliability, and local expertise. We look forward to building on the success we have achieved together and supporting their future growth across both online and retail channels.”

José Félix Herreros, Country Manager at Gran Madrid, added, “Renewing our partnership with Altenar reflects the success of our collaboration to date. Their technology, product innovation, and understanding of regulated markets have consistently helped us strengthen our sportsbook offering and meet the expectations of our customers.”

“We value Altenar’s ongoing support and commitment to our business, and we look forward to continuing to work together as we further develop our betting experience in the Spanish market.”

The renewal of this partnership not only strengthens Altenar‘s presence in Southern Europe but also underscores its dedication to providing leading regulated operators with scalable sportsbook solutions that drive long-term value and sustainable growth.
