As of November 9, 2026, the holiday calendar has already produced its first hard numbers. Adobe expects Cyber Week to generate $47.5 billion in US online spending, up 7.4 percent and 17.3 percent of the whole season, with Black Friday at $12.9 billion, up 9.2 percent. It also assigns the deepest discount of the year to a specific day for each category, and at least one of those assignments changed from last year. That makes the calendar an input to price governance, not just to media planning.
The discount curve now has dates attached
Adobe's 2026 forecast assigns each category a day when its discount bottoms out, and the assignments are not the ones most teams planned around. Electronics and computers peak on Cyber Monday, at roughly 30 and 23 percent off list price. Televisions, toys, apparel, appliances and furniture bottom out earlier, on Black Friday. Sporting goods peak on Thanksgiving Day. The day-by-day breakdown also notes that apparel moved to Black Friday this year, which quietly invalidates any plan copied from last season.
| Category | Deepest discount day | Expected peak discount |
|---|---|---|
| Electronics | Cyber Monday | 30 percent |
| Computers | Cyber Monday | 23 percent |
| Televisions | Black Friday | 23 percent |
| Toys | Black Friday | 29 percent |
| Apparel | Black Friday | 23 percent |
| Appliances | Black Friday | 18 percent |
| Furniture | Black Friday | 18 percent |
| Sporting goods | Thanksgiving Day | 19 percent |
For a brand, the calendar determines when the reference price is set and when it is tested. A category that peaks on Black Friday has less than three weeks between the first early promotions, already running in the first week of November, and its deepest point. That window is when most of the price data that matters gets created.
A calendar is only usable with a baseline
A discount number means nothing without the price it is measured against, and in the European Union that reference is defined: the lowest price applied in the 30 days before the reduction. In Italy, Netcomm and the Politecnico di Milano forecast about 4.3 billion euros of online spending during Black Friday week, up 6 percent, with 44.3 million parcels and an average discount of 25 percent. A 25 percent average only survives scrutiny if the baseline behind each claim is documented.
This is where early promotions complicate things. Amazon, Hoka and other merchants started discounting in the first week of November, with markdowns from a Ninja air fryer at $140 down from $250 to a Kate Spade wristlet cut 75 percent. If the promotion starts on November 5, the 30-day baseline reaches back into early October, a period most teams do not sample.

Reported percentages are not confirmed prices
Much of what circulates during the season is reported rather than announced. Roundups cite percentages retailers have not published, and different roundups disagree about the same brand in the same week. A price file built from those reports will not survive an audit. The workable rule is to store the page actually read, with a timestamp, and label anything sourced from a third party as unverified until the retailer's own page confirms it.
Marketplace prices move before the sale
On marketplaces the reference price is often set weeks in advance and then moved by automated repricing. A baseline sampled seven days before the event can be higher or lower than the true 30-day low, depending on when the repricer last ran. Daily sampling across the full window is the only way to know which price a compliance check would use.
Building a promotion audit trail
An audit trail is mostly discipline. Pick the twenty SKUs that carry the most promotion funding, sample them daily from 30 days before the first advertised reduction, and store three numbers per day: list price, promotional price and coupon-adjusted price. Everything else can be reconstructed; those three cannot.
The trail also ends internal arguments. When a channel claims a discount was compliant and a marketplace check disagrees, the file decides. Teams that keep it spend less time defending past promotions and more time planning the next window, which in a season that starts in early November is the difference between reacting and planning.
FAQ
Why does the category calendar matter for price monitoring?
Because each category's deepest discount falls on a specific day, and that day is when the reference price is most likely to be challenged. A category that peaks on Black Friday has a shorter window between early promotions and its low point than one that peaks on Cyber Monday.
Can a seller rely on the marketplace's price history?
It helps but is rarely sufficient. Marketplace histories usually reflect list price and may not capture coupon-adjusted prices or channel-specific promotions. An independent daily record is the safer evidence.
What changed in the 2026 forecast?
Apparel moved from Cyber Monday to Black Friday as the day of deepest discounts, and Black Friday is growing faster than Cyber Monday as early promotions pull spending forward. Plans copied from last season will be wrong on both counts.
What is the minimum viable audit trail?
Twenty SKUs, daily sampling starting 30 days before the first advertised reduction, and three price fields per observation, each with the source page and a timestamp.
