Flipkart Races Ahead in India's Fast-Delivery Wars While Rivals Lose Billions

India's top three fast-delivery firms have lost over $1.4 billion in four years. Walmart-backed Flipkart is adding about 100 small local warehouses monthly — from 340 to over 1,020 — aiming for 1,500 by end of 2026, before going public. Walmart's deep pockets give Flipkart an edge over rivals Blinkit, Zepto, and Swiggy Instamart.
