Amazon's AMZN.O India quick-commerce venture needs scaling to compete with rivals like Zepto, Blinkit, and Instamart, per Jefferies.

• Jefferies says Amazon's India quick-commerce is early stage, trails incumbents despite discounts and expanded offerings.
• Zomato (ETEA.NS) and Swiggy (SWIG.NS) stocks rise as emerging quick-commerce rivals gain traction in a crowded market.
• India's quick-commerce sector sees up to six platforms per area, including IP-bound Zepto, Flipkart's Minutes, and BigBasket.
