BOSTON, USA — July 14, 2025:
Momentum Commerce, a leading digital retail consultancy and a division of PMG, has confirmed a record-setting performance for Amazon’s Prime Day 2025, with more than $750 million in U.S. transactions tracked across hundreds of brand accounts. This milestone was reached during Amazon’s first-ever four-day Prime Day event, which demonstrated notable year-over-year growth and cemented the shopping festival’s status as a transformative retail force.
The four-day format generated a 4.9% increase in total U.S. sales compared to the combined sales from Prime Day 2024 and the two days immediately following. Momentum Commerce credits this growth to Amazon’s decision to extend the duration of the event, which gave brands more time to adjust strategies and engage consumers. According to John Shea, Head of Commerce at PMG, this year’s Prime Day required brands to be highly adaptive amid ongoing tariff concerns, evolving pricing models, and Amazon’s structural changes to the event. He noted that the final hours saw a surge in purchasing activity, driven by brands fine-tuning promotions and consumers responding with urgency.
Throughout the event, more than a quarter of products on Amazon U.S. featured discounts—an 8% rise from the previous year. Although discount participation increased, the average discount depth was slightly lower than in 2024, signaling a more strategic approach. Brands gradually increased both the number and depth of discounts over the four days, indicating deliberate pacing aimed at maintaining consumer momentum throughout the sale.
Parks Blackwell, Vice President of Marketing and Client Development at PMG, remarked that Prime Day 2025’s influence extended well beyond Amazon’s platform. She emphasized that the event spurred growth across the wider digital retail landscape, illustrating how Prime Day has evolved into a broader commercial phenomenon with cultural impact. Consumers embraced the expanded format, and the results confirmed Prime Day’s status as more than just a promotion—it is now a global retail event with ripple effects across the industry.
Momentum Commerce based its findings on data from its proprietary Velocity platform, which monitors more than $7 billion in gross merchandise volume across Amazon U.S. annually. For Prime Day 2025, the platform analyzed over 30 million products, incorporating both Prime Day-specific deals and general promotional activity.

PMG, with a team of over 1,000 employees across offices in North America, Europe, and Central America, provides end-to-end marketing services to brands including Apple, Sephora, Dropbox, Intuit, and Whole Foods.
