Intense Competition: Maplebear Inc. operates in a highly competitive market, facing pressure from rival third-party delivery services, traditional grocery retailers expanding their own delivery capabilities, and direct-to-consumer models. This competition could lead to pricing pressure, increased marketing expenses, and difficulty attracting or retaining customers and retail partners.

Reliance on Retail Partners: The company's business model heavily depends on maintaining and expanding its relationships with grocery retailers. The loss of key retail partners, a reduction in their engagement, or changes in their terms could significantly impact Maplebear's operational capacity, customer base, and financial performance.

Shopper Supply and Retention Challenges: As a gig economy platform, Maplebear Inc. relies on a large network of independent contract shoppers. Challenges in attracting, retaining, and managing these shoppers, due to factors like pay rates, working conditions, alternative employment opportunities, or legislative changes regarding worker classification, could disrupt service quality and availability.
