Many smaller firms would not be able to keep up the momentum and would either shut shop or be acquired by bigger players, the firm added.
"There is going to be a bloodbath in the market. It will all depend upon a company's capacity to bear losses. In the next 4-5 years, we expect only 2-3 big players to be present in the Indian eCommerce market," Spire Research and Consulting Senior Director (Singapore and India) Japnit Singh said here.
"We expect firms which are serving a particular geography or focussed on particular locations could survive this scenario," Singh said.
Spire Research also released its quarterly white paper, 'India's E-Tailing Industry - Seller's Perspective' 2014.

According to the report, over 54 per cent of businesses reported a growth of more than 20 per cent since going online in revenue sales.
The survey was done across 13 states on 300 retailers through one-on-one, online and telephonic communications.
According to the white paper, businesses in the apparel (82 per cent) and food (80 per cent) sectors seem to have an advantage by going online as compared to consumer electronics (72 per cent).
"There is expected growth from other sectors as well which consist of baby products, books, home decor and jewelry. Spire also forecasts that by 2020, 45 per cent of businesses will see their online share grow to between 20-50 per cent of sales," the white paper said.
On the other hand, businesses were expected to gain sales revenue from traditional/offline channels with sellers following a dual strategy of combining online with offline sales, it added.
The white paper also revealed that e-tailing space will eventually be dominated by a few large capital heavy firms given the need for nationwide logistics infrastructure and a currently limited consumer base.
