Why eBay Is Doubling Down on Live Auctions

The fastest-growing live format in North American and European commerce right now is the live auction, not the standard live stream. eBay's live commerce GMV grew more than 8x year over year on an annualized basis in Q1 2026. Whatnot, a marketplace built entirely around live auctions, drove $8 billion in live sales in 2025: close to 60% of a North American and European live shopping market worth roughly $22 billion. And in May 2026, Catawiki, Europe's largest curated auction marketplace, launched livestream auctions of its own. Shoplive lets you embed the same class of live auction capability those global platforms built, directly into your own store or app via SDK.

What is a live auction?

A live auction is a commerce format where bidding happens inside a live video broadcast, and viewers bid, win, and pay without leaving the screen. Where standard live commerce sells products at a price the seller sets, a live auction lets viewers set the price themselves, in real time. The difference lies in how the buying works, not in the interface.

A live auction makes single-unit inventory sellable on live: something standard live commerce simply can't do. Vintage goods, art, pre-owned luxury, graded cards: anything where no two items are alike.

Why are live auctions taking off in North America and Europe now?

Because three very different players arrived at the same answer at the same time. A global marketplace incumbent (eBay), a native live marketplace (Whatnot), and a traditional curated auction house (Catawiki) each converged on live auctions: and all three have published results.

eBay: why an incumbent is betting on live auctions

eBay reported $22.2 billion in Q1 2026 GMV, up 14% year over year, and named eBay Live as one of its growth drivers. On the same earnings call, eBay said eBay Live's annualized GMV run rate was more than 8x higher year over year in recent weeks.

The expansion pace is what matters. eBay Live started in the US in 2022 and has since reached the UK (June 2025), Germany and Australia (late 2025), and France, Italy and Canada (early 2026): seven countries in all. This is no longer a single-market experiment; it's becoming standard functionality.

Individual events back that up. 48 Hours of Drops, the 48-hour continuous live event eBay ran in the US in March 2026 around $1 opening bids and limited drops, beat its previous single-day live GMV record, set on Black Friday, by 60% on both days. Local 24-hour events in the UK and Germany each cleared seven-figure daily GMV. A company that has run auctions for decades is now investing to move those auctions inside video.

Whatnot: proof that live auctions can be the primary revenue channel

With Whatnot, the concentration matters more than the scale. Its $8 billion in 2025 live sales is close to 60% of a North American and European live shopping market estimated at roughly $22 billion: one format taking more than half of a regional market. Seller data points the same way: 53% say live drives the majority of their annual sales, up from 41% a year earlier, and sellers who go live daily reportedly earn 100–250x more than those streaming once or twice a month. Frequency is revenue. And while Whatnot started in trading cards, its fastest-growing 2025 categories were beauty (+791%) and electronics (+444%): evidence this format isn't limited to collectibles.

Catawiki: adding live to auctions that already work

Catawiki launched livestream auctions in May 2026, and the approach is notably pragmatic. Rather than reinventing the auction, it converts only the final 90 minutes of selected auctions into a seller-hosted live stream. Buyers who prefer to bid quietly carry on as before; only the closing tension moves into video. It started with Pokémon cards and will expand into fashion and toys. If you already run auctions, layering live onto the closing window, with no platform overhaul, is the most realistic place to start.

Why do live auctions convert better than standard live broadcasts?

Because they turn viewers from watchers into competitors. Four commerce metrics behave differently.

1. Time on stream: viewers leave a standard broadcast once the product pitch ends. In an auction they can't leave until the lot closes. Anyone who has placed a bid needs to see the outcome, so the exit point disappears.

2. Conversion: a bid is a far stronger commitment than adding to cart. A viewer who bids has already decided to buy; winning leaves only the payment step. That's why conversion rate rises structurally.

3. No price ceiling: with fixed pricing, the seller's price is the revenue ceiling. An auction lifts the price to what the market will actually pay. The scarcer the item, the wider that gap.

4. Community: competitive bidding plus chat creates relationships between viewers. A regular schedule builds a fandom, and that fandom becomes the next session's bidders.

Why is WebRTC essential for live auctions?

WebRTC stands for Web Real-Time Communication: a technology for exchanging audio, video and data in near real time directly in a web browser. Because it meets both of the things an auction demands, sub-second latency and two-way, real-time communication, WebRTC is a hard requirement for any live auction solution. Plenty of vendors advertise "low latency" but actually run LL-HLS. If a bid placed three seconds before close lands on screen five seconds later, the viewer is bidding on an auction that already ended. So the question to put to a vendor is not "do you support low-latency streaming" but "is this WebRTC-based, and what is the measured latency?"

HLS vs. LL-HLS vs. WebRTC

Why is WebRTC hard to implement?

WebRTC was designed for one-to-one video calls. Scaling it to a broadcast watched by thousands or tens of thousands means solving four problems yourself.

• You can't use an ordinary HTTP CDN. With HLS, a CDN copies finished segments to tens of thousands of viewers. WebRTC maintains an individual connection per viewer, so caching and replicating files doesn't apply: you have to build and operate media servers (SFU) that relay every connection. More concurrent viewers means more servers.

• Quality has to be tuned per connection. Network conditions differ for every viewer. But drop the quality too far and buyers can't assess the item, which defeats the purpose of the auction.

• Dropped connections must recover instantly. Leaving the app or switching between Wi-Fi and cellular breaks the connection. Slow recovery means missed bids.

• Some environments block the connection outright. Corporate firewalls and similar setups require relaying through a TURN server.

In short, "we support WebRTC" and "we run WebRTC reliably at commercial scale" are entirely different claims. That gap is where live auction vendors separate.

Can you build an eBay Live–style auction on your own store with Shoplive?

Yes. A live auction needs six technical requirements that standard live commerce solutions don't cover, and Shoplive provides all six. A live auction is a real-time transaction system where money changes hands second by second, not a bid button layered over video. In a standard broadcast, latency or a dropped frame costs you viewing experience. In an auction, the same fault costs you disputed sales and refunds. These six are what to verify with any vendor: and what Shoplive already ships.

Miss any one of the six and a live auction either can't run or starts generating disputes. Shoplive delivers them not as separate options but as one complete auction cycle: list the lot, take live bids, close automatically, confirm the winner, hand off to payment: with no break in the chain, on top of WebRTC streaming and PIP by default. The closing minutes are when viewership peaks and the highest bids arrive at the same time, so holding resolution through that window feeds directly into the final price.

Shoplive has provided live commerce solutions to more than 200 brands across 20-plus countries since 2020, with 320 million cumulative viewers and over 1,000 broadcasts a day. Here, WebRTC is running in production every day, not sitting in a pilot.

There are plenty of live commerce solutions. Why Shoplive?

Because live auctions require three things at once, and almost nothing sits at that intersection.

1. Sub-second WebRTC streaming: the auction only works if the host's call and the screen agree.

2. The full auction transaction: eligibility, concurrent bids, winner determination, payment handoff. A live auction is a transaction feature, not a video feature.

3. An SDK that embeds in your own store and app: keep customers in your service and the customers, transaction data and brand stay with you (D2C live commerce).

Most options on the market deliver only one of the three.

Shoplive delivers all three in a single SDK. What global platforms built internally at considerable cost, you can add to your own service through an SDK integration rather than a development project.

Operational features

Beyond the six requirements, Shoplive ships the operational tooling you need to actually run broadcasts. Implementation details are in the auction operations guide and the auction integration docs.

Which industries should adopt live auctions?

Anyone selling items where no two are alike or items with a fandom. The harder a product is to price on a fixed tag, or the more that fixed tag leaves on the table, the bigger the gain.

How do you get started with live auctions?

Four stages: define auction policy, integrate the SDK, rehearse operations, then commit to a regular schedule. Time spent on policy and rehearsal pays back more than time spent on integration.

1. Define auction policy: fix your starting price, bid increment and lot duration; bidding eligibility (membership tier, identity verification); the payment deadline and penalty for non-payment; and how unsold lots are handled. The issue that bites most often in live auctions is winners who don't pay, not anything technical.

2. Integrate: embed the Shoplive SDK in your app or web store and control bidding rights with canBid at authentication. Wire the buy-button event fired on a win into your existing checkout and order systems.

3. Rehearse operations: run a full rehearsal covering how fast the host calls bids, the closing countdown script, and what happens when a lot goes unsold. In an auction, the host's skill moves the final price directly.

4. Commit to a schedule: as Whatnot's data shows, frequency is revenue. Don't treat it as a one-off event: fix the day and time and build a fandom.

Frequently asked questions

Q. How is a live auction different from standard live commerce?
A. Standard live commerce is a broadcast selling products at a price the seller sets, while a live auction is a broadcast where the price is determined by viewers bidding against each other in real time. A live auction can sell single-unit rarities, and because viewers stay until the lot closes, both time on stream and conversion rise together.

Q. What is the most important technical requirement for a live auction?
A. WebRTC-based sub-second two-way streaming. If the price on screen diverges from the price on the server, you get disputed sales, so latency has to stay under one second: and WebRTC is effectively the only technology that delivers that. Everything else can be built later, but the streaming protocol is an architectural decision you can't swap out afterward, so check it first.

Q. Can't you run a live auction on low-latency HLS?
A. Not adequately. Standard HLS carries 6–30 seconds of latency and LL-HLS 2–5 seconds, so a bid placed three seconds before close that lands on screen five seconds later is a bid on an auction that has already ended. Many solutions advertise "low latency" while actually running LL-HLS, so ask whether it is WebRTC-based and what the measured latency is.

Q. Are all WebRTC-capable solutions equivalent?
A. No. WebRTC was designed for one-to-one communication, so scaling it to large broadcasts means operating SFU media server infrastructure instead of ordinary HTTP CDN caching, plus per-viewer network adaptation, mobile reconnection, and NAT and firewall traversal. "We support WebRTC" and "we run it reliably at commercial scale" are different claims: in particular, check whether resolution holds through the closing window when traffic peaks.

Q. Can live auctions be added to our own app or store?
A. Yes. Shoplive's live auction ships as an SDK that embeds in your app or web store, so auctions run inside your own service without sending customers to an external platform. Control bidding rights with canBid at authentication, and wire the buy-button event fired on a win into your existing checkout and order systems.

Q. Which products suit live auctions?
A. One-of-a-kind items and items with a fandom suit them best: collectibles and trading cards, luxury and watch resale, art, limited-edition sneakers, fan merchandise, used cars, source auctions for agriculture and seafood, and B2B carryover stock. On Whatnot, beauty grew 791% and electronics 444% year over year in 2025, showing the format is expanding well beyond collectibles.

Q. We already run an auction service. How should we start?
A. We recommend the Catawiki approach. Catawiki didn't change the whole auction: it converted only the final 90 minutes of selected auctions into a seller-hosted live stream, and one in four items sold in its live auctions is now won during the live stream. Because the existing bidding flow stays intact and live sits only on the closing window, the risk is low.
