Overview
- Mercado Libre says there are no user-specific prices on its marketplace and that list prices are set by sellers rather than segmented by profile.
- The company attributes simultaneous price differences to short A/B promotions that include randomly selected control groups for measurement.
- Mercado Libre notes that its Ajuste Automático de Precios lets sellers set minimum and maximum ranges so the platform can keep listings competitive.
- When the automatic adjustment runs, the company says the resulting price applies uniformly to all shoppers at that moment.
- The issue gained traction after users shared screenshots, including a 20% gap highlighted by economist Ariel Setton, as social media skepticism continued without independent verification of systematic personalization or reported regulatory action.
