Altenar adds in-play Bet Builders to MLB betting offering
Sportsbook provider Altenar has broadened its Major League Baseball content for the 2025 season, introducing live Bet Builders and a wider range of prop bets for US operator partners.
Altenar has expanded its Major League Baseball (MLB) offering ahead of the 2025 season, adding in-play Bet Builders and an enlarged suite of prop betting markets for its US-facing operator partners.
The new in-play Bet Builder tool allows bettors to construct wagers during live MLB games, tapping into what the supplier describes as growing demand for this type of bet. Alongside this, Altenar has widened its pre-match and live prop betting catalogue, covering player, team and game-based markets.
The MLB update builds on Altenar’s existing suite of baseball products, which already includes fast markets, micro-betting, same-game parlays, player specials and pitcher lines.
Data partnership underpins new markets
The expanded content is powered by data from Swish Analytics, an official MLB data distributor since 2019. Altenar said the data feed supports the creation of detailed and responsive betting markets now being rolled out to its operator partners.
Antonis Karakousis, Director of Operations at Altenar, said the company aims to keep advancing its US sports betting product, with plans to further develop pre-match, in-play and at-bat offerings for MLB. He added that improving the Bet Builder experience remains a core part of the company’s product roadmap.
Industry showcase
Altenar is set to present its updated sportsbook terminal, including the new MLB features, at SBC Summit Americas 2025, taking place from 13 to 15 May.
The update was announced by Altenar, a turnkey sportsbook provider founded in 2011.
