The forecast: After a spike in growth in 2020, multichannel ecommerce sales will continue to grow faster than nonstore ecommerce and take up increasingly larger shares of the total ecommerce market.
Insider Intelligence projects US nonstore ecommerce sales will grow by 17.2% to reach $516.11 billion in 2021, taking up 55.3% of total ecommerce sales.
The rest of the market will be taken up by US multichannel ecommerce sales, which will grow an estimated 18.8% to reach $417.18 billion in 2021.
Looking ahead: Forecasters expect multichannel sales to make up close to 46% of all ecommerce sales by 2023, up from 40.3% in 2019. That said, nonstore retailers will still dominate over 54% of the market, with sales approaching $687 billion.
