The show, which stars David Strathairn and Ryan Cartwright, focuses on five people who use their superhuman abilities to fight injustice.
Writing on the cable network's official Twitter account, Syfy senior executive Craig Engler said: "There is no truth to the rumours some have asked me about that Alphas was cancelled. They are literally filming new eps as I type this."
Five episodes of Alphas have aired, with the most recent instalment 'Never Let Me Go' pulling in just over 2 million viewers.
The Cape actress Summer Glau and Raising Hope star Garret Dillahunt will appear in forthcoming episodes.
Syfy recently announced that it had cancelled drama series Eureka after five seasons, but also ordered an additional episode to serve as the show's finale.
Alphas continues on Mondays at 10/9c on Syfy.
