What Is Cyber Monday?

A press release in the autumn of 2005 gave a name to something shoppers were already doing: going back to the office on Monday and buying online what the stores had sold out of on Friday.

What Is The Definition Of Cyber Monday?

Cyber Monday is the Monday after US Thanksgiving, a day of online-first shopping promotions that is now most closely tied to electronics. That is the working definition retailers and analysts use, and it explains why the date moves: in 2025 it was December 1, in 2026 it is Monday, November 30.

Two details sharpen it. First, it is a marketing label and not a holiday, so nothing official defines when a store's offers start or stop. Second, it is no longer limited to one Monday. Many sales begin days earlier and run days later, and Amazon has called its recent version of the event Black Friday Week.

When does Cyber Monday begin in a given year? The Monday after the fourth Thursday of November, which is why the full calendar sits on when is Cyber Monday.

Where Did The Name Cyber Monday Come From?

The term was coined by Ellen Davis of the National Retail Federation's Shop.org, and it first appeared in a press release on November 28, 2005. The idea was simple. Shop.org noticed that online sales jumped on the Monday after Thanksgiving, and it gave that jump a catchy label.

The name reflected the era. In 2005 many people did their online shopping at work, where broadband was faster than at home, and the Monday after the long weekend was the first chance to do it. The word cyber was how people talked about the internet then, and it stuck even as the internet moved to every pocket.

Retailers jumped on it quickly. A label that had started as a description of consumer behavior became a deliberate event, with promotions timed to match. It is now one of the best-known shopping days of the year in the US, and the date for 2026 is Monday, November 30. You can find the full calendar at when is Cyber Monday.

It is worth remembering how small the idea was at first. There was no coordinated event, no countdown timer and no app notification. There was a pattern in the sales data, and a trade group that gave the pattern a name. Everything that followed, from dedicated landing pages to week-long promotions, was built on top of that label by retailers who saw it working.

How Big Has Cyber Monday Become?

Very big. Adobe Analytics reported that US online spending on Cyber Monday 2025 was $14.25 billion, up 7.1% year over year. That compares with $11.8 billion on Black Friday 2025 and $44.2 billion across the five days from Thanksgiving through Cyber Monday.

Two other details from the same Adobe data say a lot about how people shop now. Mobile accounted for 57.5% of Cyber Monday online spending, so the typical purchase is made on a phone, not a desk computer. And buy now, pay later services were used for $1.03 billion of Cyber Monday spending, which suggests many shoppers split bigger purchases like laptops and TVs.

Adobe also reported the peak discounts it saw by category on Cyber Monday 2025:

These are peaks, not averages. Adobe's 2026 forecast is covered in the next section.

Is Cyber Monday Still A Thing In 2026?

Yes, and by Adobe's numbers it is still growing. Adobe Analytics reported that US online spending on Cyber Monday 2025 reached $14.25 billion, up 7.1% year over year, the biggest single day of that Cyber Week.

For 2026, Adobe's forecast, published September 28, 2026, projects $15.1 billion on Cyber Monday, up 6.2%. It would be the first single online shopping day ever above $15 billion. Adobe forecasts $12.9 billion for Black Friday and $47.5 billion for Cyber Week, inside US online holiday spending of $275.1 billion for November 1 to December 31, up 6.7%.

The caveat is that these are forecasts. What has changed is the shape of the event, not its relevance: sales now start before Thanksgiving and spill past the Monday, so Cyber Monday has become the peak of a long run instead of a single day. Skeptics who say it is dead are usually pointing at that blur, not at the spending. For tech, you can see the live version on the Amazon tech deals hub.

How Does Cyber Monday Relate To Black Friday And Cyber Week?

Black Friday is the Friday after Thanksgiving, historically a day of in-store sales. Cyber Monday is the Monday that follows the weekend, historically the online counterpart. In 2026 those fall on November 27 and November 30.

Today, the distinction is mostly about habit. Black Friday deals appear online and in stores, Cyber Monday deals appear online, and many retailers run overlapping sales across the whole week. The window from Thanksgiving through Cyber Monday is what Adobe calls Cyber Week, though the term is a marketing label, not an official one, and retailers define it their own way.

If you are deciding which day matters more for what you want to buy, read Cyber Monday vs Black Friday, which compares the two on spending, discounts and product type.

One more wrinkle: because the date follows Thanksgiving, it shifts. It was December 1 in 2025, it is November 30 in 2026, and it will be November 29 in 2027 and November 27 in 2028. The label stays the same while the calendar moves around it.

Why Is Tech The Heart Of Cyber Monday?

Because tech is the easiest thing to sell online and the hardest to compare in a store. A buyer can read specs, check prices and have a TV or a laptop delivered without walking a showroom floor. The product is also standardized: a model number means the same thing in every box.

That makes electronics the biggest target for discounts. In Adobe's 2025 numbers, electronics had the highest peak discount of any category it reported, at 31%. Computers and televisions followed at 23% and 22%.

It also makes it easy to be fooled. A discount on tech depends on which reference price you use, which model year you are buying, and which configuration is in the box. Start with the category pages for TVs, laptops and Nintendo Switch, or see the biggest live savings on the Amazon tech deals hub.
