Home Depot Inc. has made an offer for GMS Inc., potentially setting off a bidding war with QXO Inc. which this week made a $5 billion offer for the building-products distributor, the Wall Street Journal reported Thursday.

You’ve heard of Home Depot. But have you heard of QXO, a relatively new company in the building supplies industry? Probably not. That could soon change. There’s a chance that QXO may go toe to toe with the mighty home improvement retailer in a bidding war for materials distributor GMS.

Home Depot made a buyout bid for buildings-products distributor GMS, the WSJ reported, a year after it bought SRS Distribution for over $18 billion.
