That really depends on how it's adapted. Phantom Bullet was two volumes long in the books and was adapted into fourteen episodes. Alicization is currently six volumes long, with another booking coming out in August, and still not finished yet. So, if adapted faithfully, Alicization might need about forty episodes. Depending on adaptation choices, it might be squeezed into a two-cour season by omitting the not-so-important content or changing the content to be less long. Or it could be done in two seasons, one for each sub-arc, though the sub-arcs are far from being equal in size so it could be problematic. Or it could be done as an unusual 3-cour season etc.. Depends on how the anime studio decides to handle the content. And the arc is not even fully published yet. The author may still change or expand the story that hasn't been published yet, like how the majority of volume 10 was original content to fill in the timeskips a bit.
