Being infinite, it has no shape. The observable universe is a sphere.

Explanation:

The entire universe cannot have a shape because it has no boundaries. Because light travels at a constant speed in the vacuum of space, we can see equally far in every direction (the distance is limited by the sheer size vs the time light has had to get to us), thus making the observable universe a sphere.
