Prime Day kicks off with $8.3 billion in US online spending, Adobe raises its retail forecast

Prime Day got off to a fast start for US e-commerce, with online spending reaching $8.3 billion in the early phase of the multi-day event, according to figures cited by Yahoo Finance. The report attributes the spend tracking to Adobe, which monitors digital retail performance through its analytics tools.

Adobe’s outlook for the full four-day Prime Day period calls for $26.3 billion in online spending in the United States. That would represent an increase of 9% versus the same period last year, indicating continued consumer demand despite a higher-cost environment that has pressured many discretionary categories.

Prime Day is Amazon’s annual shopping promotion, typically spanning multiple days and marketed for deals on everything from consumer electronics to household staples. In practice, the event has become a major test of the broader retail environment, with online spending often used as a high-frequency indicator of how the US consumer is behaving.

The early $8.3 billion figure suggests the deals were met with brisk traffic and conversion in the initial window, which matters for retailers because early sales can influence inventory planning and downstream marketing efforts. For Amazon, stronger initial momentum can also support seller participation, since many merchants plan inventory and promotions around expected demand patterns.

Adobe’s forecast framing also highlights that analysts are now treating Prime Day less as a single-day discount burst and more as a measurable, forecastable slice of the digital retail calendar. The move from initial sales to a full-period estimate of $26.3 billion underscores how tightly digital retail is being tracked as a near-real-time business metric.

Still, the headline numbers do not explain how much of the spending was driven by specific categories, payment methods, or delivery speeds. The Yahoo Finance report focuses on aggregate online totals rather than the underlying drivers that often explain why spending rises in some years and stalls in others.

Another uncertainty is how the event’s sales distribution compares across US regions and among different retailers. The information provided centers on US online spending totals and a forecast for the full event, without breaking out contributions by major brands or mapping the data to Amazon’s own sales performance directly.

What to watch next is whether the four-day total ultimately aligns with Adobe’s $26.3 billion expectation and whether day-by-day pacing remains consistent with the initial surge. If early momentum persists, it would reinforce the case that Prime Day continues to pull incremental demand into e-commerce during the summer retail season.
