Did they cut any joints in it? If not, then the concrete jointed itself by cracking.
Actually, I don't think I've ever seen a basement slab that wasn't cracked. The cracks are drying shrinkage cracks, and they usually happen the day after the pour. That's what cut joints are control where the slab cracks.
Usually, an indoor crack is not a "working crack" affected by changes in temperature, freezing, etc., so they pose no problems other than aesthetics. This is especially true if you are carpeting over it anyway. No worries.
