Live selling in the UK is developing quickly, but the major platforms are not all approaching it in the same way.
Whatnot is built around live commerce. Tilt has developed as a specialist live-shopping marketplace. eBay is expanding Live within its established marketplace, while TikTok Shop is introducing auction mechanics into its existing social-commerce ecosystem.
For sellers, that makes simple platform comparisons difficult.
The companies also disclose growth in different ways. Some talk about seller adoption, others about sales activity, buyer growth or wider platform expansion. Rather than trying to turn those different measures into a league table, it is more useful to look at the direction each platform is taking and the stage its live-auction product has reached.
Whatnot: the most established dedicated live-selling model
Whatnot is the most mature dedicated live-selling platform in this comparison.
Live selling is central to the platform rather than an additional feature within a broader marketplace, and Whatnot has continued to report strong growth across its live-commerce business, including expansion among UK buyers and European sellers.
That matters when comparing Whatnot with newer entrants.
A new feature can grow rapidly from a relatively small starting point. Whatnot's growth is occurring within an already established live-commerce marketplace.
For UK sellers, Whatnot therefore provides the clearest example of a mature audience already familiar with live bidding, auctions and seller-led shows.
The interesting question now is how the market develops as other platforms build their own approaches to the same format.
TikTok Live Auction: a new auction format within a much larger ecosystem
TikTok's position is different.
The relevant comparison here is not ordinary TikTok LIVE shopping, but TikTok Shop's newer Live Auction functionality.
The feature introduces countdown bidding and highest-bidder-wins mechanics that make it much more directly comparable with platforms such as Whatnot and Tilt.
Public UK data is still limited because the feature is relatively new, but early activity suggests growing adoption, particularly around categories already well suited to live selling such as sneakers, streetwear and collectibles.
TikTok's distinctive advantage is its existing discovery environment. Sellers operate within a platform where audiences already discover products, creators and trends through short-form video and livestream content.
The question over the next year will be how successfully that existing behaviour translates into regular auction participation.
For now, TikTok Auction is best viewed as an early-stage but rapidly developing live-auction channel rather than a mature marketplace with directly comparable public scale data.
eBay Live: developing live commerce within an established marketplace
eBay is approaching live commerce from another direction.
Rather than creating a separate specialist marketplace, it is integrating Live into its existing ecommerce platform.
eBay has reported strong growth for Live across the markets where the service operates, although the company does not currently provide enough UK-specific information to make straightforward comparisons with the other platforms.
The UK rollout is still relatively young, but eBay has already been expanding live events across categories including trading cards, fashion, beauty, electronics and sports memorabilia.
eBay's starting point is unusual because it already has a mature marketplace, large seller base and established buyer behaviour.
Its live-selling development therefore depends less on building an ecommerce audience from scratch and more on encouraging existing marketplace users to engage with a different purchasing format.
That makes eBay Live particularly interesting to watch as the product becomes more widely established.
Tilt: a specialist platform continuing to expand
Tilt occupies a different part of the market again.
Like Whatnot, live commerce is central to the product rather than an additional feature.
The company has reported substantial growth since its earlier funding rounds and has continued expanding its buyer and seller community across several European markets.
Its strongest visibility has been around areas such as fashion, vintage, streetwear, sneakers and collectibles.
Because Tilt operates across several countries, its published audience figures shouldn't automatically be interpreted as UK audience numbers.
Nevertheless, its continued expansion indicates that specialist live-commerce platforms are attracting buyers and sellers alongside the larger marketplace and social-commerce companies entering the space.
Four different routes into live selling
The more useful comparison is how each platform is building its live-selling proposition.
Whatnot
A dedicated live-commerce marketplace with an established buyer and seller base already accustomed to live auctions.
TikTok Live Auction
A newer auction format being introduced within a much larger social-commerce and content-discovery ecosystem.
Tilt
A specialist live-shopping platform with a particular presence in fashion, streetwear, vintage and collectibles.
eBay Live
A live-commerce layer being developed within one of the world's longest-established online marketplaces.
Those differences matter because sellers are unlikely to evaluate the platforms on growth alone.
Category fit, audience behaviour, seller tools, discovery, fees, fulfilment and how naturally a particular product works in a live environment may ultimately matter more than headline platform size.
What does this mean for UK sellers?
The clearest conclusion is not that one platform has “won” live selling.
It is that live auctions are becoming a more established part of mainstream ecommerce.
Whatnot continues to expand from an established live-selling base.
Tilt continues to develop as a specialist live-commerce platform.
eBay is extending Live within its existing marketplace.
TikTok is now introducing auction mechanics into one of the world's largest social-commerce environments.
For UK sellers, that creates more choice.
It also means that the live-selling market should probably no longer be viewed as a single-platform category.
Different platforms are developing different audiences, seller communities and approaches to live commerce.
Whatnot starts with live selling.
TikTok starts with content and discovery.
eBay starts with an established ecommerce marketplace.
Tilt starts with a specialist social-shopping experience.
None of those approaches automatically makes one platform better than another.
For sellers, the more useful question may therefore become less:
“Which platform is biggest?”
and more:
“Which platform currently fits the products I sell, the audience I want to reach and the way I prefer to sell?”
