Short-term growth in the US pet e-commerce market is likely to continue to be driven primarily by retailers Chewy and Amazon. Scenario analysis shows that these two retailers will account for a total market share of 70%, with Chewy slightly higher at 36%. The competition between the two companies in terms of pricing is fierce, but Chewy hopes to increase the share of consumers' wallets by expanding into areas beyond product retailing through its Chewy Health business unit, including complex medications, insurance, and veterinary services. This is expected to increase customer stickiness, expand the company's potential market size by $32 billion, and enhance the company's profitability.
