Prime Big Deal Days ran October 6–7, 2026, Amazon's last major sale event before the holidays. For brands it doubles as a rehearsal for Black Friday and Cyber Monday: the same shoppers, the same deal-hunting mindset, and a clear read on how demand moves hour to hour. Here is what our team saw while running campaigns through the event, and what we are changing for Q4.
Market snapshot: Prime Big Deal Days 2026 (Oct 6–7)
Was Prime Big Deal Days 2026 a success?
Yes. Adobe Analytics measured $9.86 billion in US online spending across all retailers over October 6–7, up 8.5% YoY, and growth accelerated from 2025's 7.3% (Digital Commerce 360). Mobile accounted for 52% of those sales.
Amazon itself pointed to millions of items at their lowest price of the year so far, hundreds of thousands discounted 40% or more, and deals from thousands of brands (Chain Store Age).
On the ground, the brands we manage saw the same picture. Event days ran far above a normal day, and the event added to each brand's growth rather than simply riding along with it. Growth was broad, not carried by one or two outliers, and it showed up across large, mid-size and smaller brands alike.
"Growth wasn't reserved for the biggest brands. Small and mid-size brands grew right alongside them. What separated winners from the rest wasn't ad budget. It was preparation: deals, inventory and listings locked in well before the event."

Day 1 vs Day 2: the second day held its own
A common assumption is that the opening day does the heavy lifting and Day 2 fades. That is not what we saw. Both days performed equally.
Shoppers also didn't wait for the starting gun. Sales on the eve of the event were already running above a normal day, so the build-up started before the first deal went live.
The post-event slump? Not so much. The usual fear is that a big spike is followed by a crash that flattens the month. Instead, the day after the event saw only a mild slowdown below normal levels. The gains from the event were not given back.
Hour by hour: the golden hours
Every hour of both event days ran above a normal day, but the lift was uneven. The event opened with a burst right after midnight Pacific. Mornings then settled into the smallest lift of the day before demand climbed again into the evening.
Day 2 showed the pattern most clearly. Sales built through the afternoon, peaked around 6pm Pacific and stayed high late into the night. The final hour of the event delivered the biggest lift of any hour, as shoppers came back for one last look before the deals closed.
The takeaway: 6pm to midnight Pacific, normally the quietest stretch of the day, was where the event's strongest lift sat.
"Day 2 is where a lot of brands leave sales on the table. Demand held level with Day 1, and the final hours of the night delivered the biggest lift of the whole event. We plan budgets so campaigns stay live right up to midnight on the last day, and we push bids harder through those closing hours, because that is where the real conversion opportunity sits."

Categories: the everyday aisle led
Shoppers used the event to stock up, not to start their gift lists. Numerator's Day 1 data put Premier Protein shakes, Scott ComfortPlus toilet paper, Lysol wipes and Dawn Powerwash among the top-selling items, with household essentials, health & wellness and beauty the most-bought categories (Chain Store Age). eMarketer's read of the same data: most spending went to everyday essentials, and 68% of items cost under $20 (eMarketer).
We saw the same pattern in the accounts we run:
- Food & Beverage brands arrived already growing fast all year, and the event extended that run.
- Air, Water & Home Environment saw some of the sharpest event-day spikes over a normal day.
- Health, Household & Medical moved in step with shoppers stocking up on essentials.
The lesson for Q4: replenishable products win when shoppers are in stock-up mode, and categories with strong momentum before the event got the most out of it.
Did advertisers show up?
They did. Triple Whale's benchmark of about 2,000 brands found average daily Amazon ad spend rose roughly 149% during the event, and Amazon's share of total ad budgets more than doubled versus the prior week (Triple Whale). Their read was that efficiency held up as spend scaled.
More advertisers chasing the same shoppers means clicks cost more. That is expected, and it is not the number to judge the event on. What matters is whether conversion rises enough to pay for it. In the campaigns we managed, it did: shoppers arrived ready to buy, so each click was worth more than on a normal day.
"Cost per click always climbs during an event, so we don't judge the day on CPC. We watch TACoS. If it holds, the extra spend is buying real sales."
— Joshua, Demand Lead, Xneeti
5 takeaways for BFCM and Q4
Prime Big Deal Days is the closest preview of holiday demand brands get. Here is what we are carrying into Black Friday, Cyber Monday and the rest of Q4:
"The event rewards brands that are visible in the hours that matter and disciplined in the hours that don't. That's the plan we're taking into Black Friday and Cyber Monday."
