How TikTok Shop Quietly Became the Fastest-Growing E-Commerce Platform in the United States

Two years ago, the majority of e-commerce executives would have grinned courteously and moved on if you had told them that a short-video app that was mostly known for dance trends and audible sound effects would be generating $1 billion in monthly retail sales in the United States. At the time, the concept appeared to be truly unrealistic. Instead of making purchases, people visit TikTok to watch content. That was the general consensus. TikTok completely disregarded it.

After months of testing in the UK and some regions of Southeast Asia, TikTok Shop debuted in the US in September 2023. There were conflicting reactions at first. Concerns about invasive product tags clogging their feeds were voiced by users. Changing from entertainment to salesmanship made some creators uncomfortable. The not-insignificant question of why anyone would give their credit card information to an app that Congressmen were concurrently claiming posed a threat to national security loomed over all of this. By most accounts, it was a difficult beginning. Then something changed.

The Information reported that by July 2024, the platform was making about $1 billion in monthly sales in the United States. In less than two years, that amount had increased from about $15 million per month at launch. This increase is nearly unprecedented in the history of American e-commerce. To put things in perspective, Amazon took years to establish the infrastructure and customer confidence necessary to become the go-to place for online purchases. One structural change made by TikTok Shop was that it didn’t ask customers to go shopping. It transported the store to their current location, inside a video they were already watching, with a person they already followed and, to varying degrees, trusted.

It was impossible to ignore the numbers after Black Friday in 2024. TikTok Shop made $100 million in sales in a single day, which is three times more than what it made on the same day in 2023. U.S. sales totaled $500 million during the entire Black Friday through Cyber Monday weekend. In just four days, a platform that was nonexistent in America twenty-six months prior generated half a billion dollars. Creator-economy analyst Jake Bjorseth, who has been closely observing TikTok Shop’s expansion, characterized it as a distribution success rather than a marketing one, stating that it was the first time in the history of American commerce that content, culture, and checkout all existed in one continuous motion. You trusted the creator, you saw them, and you made a purchase through them. Don’t change tabs. No need to look up prices on Amazon. Simply observe and purchase.

This framing is important because it clarifies what TikTok Shop is, which is different from what most people believe. It’s not a marketplace in the conventional sense, like eBay or even Amazon, where customers come with a purpose and look for particular products. It’s more akin to the opposite—a system in which the product finds you, typically while you’re engaged in another activity, accompanied by a creator whose endorsement has greater persuasive power than any display advertisement. After tracking 80,000 orders through TikTok Shop, Bryan Porter, co-founder of the housewares company Simple Modern, discovered that 60% of his sales came from video content, the majority of which was produced by affiliate creators who already owned the product. Advertising was not the reason for the conversion. It happened as a result of someone on camera saying, “This is good,” in their car, kitchen, or bathroom.

The creator-as-storefront model is a significant shift from the way retail has operated for many years, so it’s worth taking a moment to consider it. The big-box retailer replaced the department store, which in turn led to the search-optimized Amazon listing, which may now be giving way to something more human and more difficult to duplicate using algorithms alone. Porter discovered something surprising when he examined revenue by affiliate follower count: creators with 50,000 followers outperformed those with a million followers per video. It’s not the reach. The key is the relationship. It lacks that, but Amazon offers two-day shipping on all products.

The story of TikTok Shop is further complicated by the demographic picture. It turns out that the notion that its expansion is solely a Gen Z phenomenon is untrue. According to data from NIQ in Germany, one of TikTok Shop’s more recent markets, Gen X customers—those in their 40s and 50s—actually account for a higher percentage of sales than Gen Z. 36% as opposed to 32%. It seems that people in their 40s are discreetly spending more than teenagers. TikTok Shop has proven particularly popular among young consumers in the United States, which has long-term ramifications for Amazon. However, the German data indicates that the appeal is more widespread than the brand identity suggests and that effective, low-friction product discovery is effective regardless of a person’s upbringing.

Observing all of this, it seems as though the retail sector is still learning the full impact of TikTok Shop on the competitive environment. In response, Amazon created its own short-video feed and increased its investments in influencer marketing and live shopping. Walmart has taken comparable actions. This is a significant statement about two of the world’s most resource-rich retail businesses: neither has been able to match TikTok Shop’s growth trajectory. In 2024, the platform’s worldwide GMV reached $33.2 billion. With $19 billion in global merchandise sales in its third quarter alone, it is comparable to eBay by some metrics, a comparison that would have seemed ludicrous a short time ago.

The growth curve’s viability is still up for debate. The ability to make products go viral overnight is TikTok Shop’s greatest asset, but some sellers have found it to be a liability. Millions of dollars can be made from a product in a single week without affecting the rest of the brand’s inventory. When demand is controlled by the erratic physics of virality, inventory planning becomes truly challenging. Even though the immediate threat of a U.S. ban has temporarily subsided, the legal and political uncertainty surrounding TikTok itself hasn’t completely disappeared. Not every merchant will be willing to take the calculated risk of building a significant portion of a business on a platform that Congress has repeatedly attempted to restrict.

The way Americans find and purchase goods has undoubtedly changed, and TikTok Shop is at the epicenter of this shift. Quietly, the company that created a platform for three-minute videos is now among the nation’s most disruptive retail forces. It’s unlikely that Amazon is in a panic. However, it is listening. And that’s an accomplishment in and of itself for a two-year-old commerce platform.
