Forrester expects that global retail will top $28 trillion by 2028, up from $22.6 trillion in 2023. Three-quarters of that will be in physical stores, and the remainder will be online.

It also reviews three technology areas that retailers should invest in to boost retail sales: AI, retail media, and mobile commerce.
