What is a raid train on Whatnot?

Whatnot sellers raid into each other in a set order, passing viewers down the line. How raid trains work, and how to find and join one on Raid Train Express.

A raid train is a group of Whatnot sellers who raid into each other in a set order, so each seller’s viewers carry over to the next show. Most trains are organized on Raid Train Express, our partner, where you can find a train and sign up for a slot.

If you sell on Whatnot, you’ve probably heard people talk about “hopping on a train” or “running a raid train.” It sounds like jargon, but the idea is simple, and it’s one of the best free ways to grow a live audience.

Raid trains are organized on Raid Train Express, our partner. For a specific train’s slots, lineup or rules, message its organizer on Whatnot. For how Raid Train Express itself works, see the Raid Train Express help center.

The short answer

A raid train is a group of Whatnot sellers who agree to raid into each other in a set order. When one seller finishes, they raid the next seller and their viewers follow. That seller sells for a while, then raids into the next, and so on down the line. The same pool of buyers gets passed along, so everyone on the train gets a burst of fresh viewers they wouldn’t have reached on their own.

Think of it like a relay race for audiences. Each seller runs their leg, then hands the crowd to the next.

Raid trains aren’t a Whatnot feature. Whatnot’s help center covers raids but never mentions trains: sellers organize them among themselves and use Whatnot’s ordinary raid for each handoff.

First, what a raid is on Whatnot

A raid is how a seller ends a show: it sends the seller and their viewers straight into another seller’s live show. From Whatnot’s help center as of October 21, 2026:

• Starting one. In the app, tap More on the right of your show, choose Raid, pick a seller, then Raid Now and Continue. On whatnot.com, it’s More, then Seller Tools, then Start Raid. Or type /raid @username in chat. You can also let Whatnot pick a seller for you, which a train never does.
• It ends your show. Starting a raid automatically ends your live stream, so on a train, raid only when your slot is truly done.
• The other seller has to be live. You can only raid someone who’s streaming at that moment. That’s why every seller on a train goes live before their slot, not at it.
• What the next seller sees. A public message in their chat, like “yourfavoriteseller is raiding with a party of 12.” That’s the cue to thank the raider and welcome the crowd.
• Viewers can step off. Anyone can leave before the raid starts or leave the new show at any time, which is why a warm welcome matters.

How a raid train works, step by step

1. An organizer sets up the train. They line up a group of sellers, often in the same category: sports cards, Pokémon, sneakers, vintage.
2. Everyone gets a slot and a time. The organizer sets the running order: who goes first, who’s next, and when each person should be live.
3. Sellers go live in order. When it’s your turn, you’re already streaming, because Whatnot only lets a seller raid a show that’s live.
4. Each seller raids into the next. At the end of your slot, you raid the next seller in the line and your viewers travel with you.
5. The audience compounds. As the train moves, viewers pick up momentum, and each seller gets in front of buyers from everyone earlier in the chain.

Why sellers ride raid trains

• Free audience growth. You’re borrowing reach from every other seller on the train instead of paying for ads.
• New followers and buyers. Viewers who find you on a raid often follow and come back to future shows.
• Community. Trains build relationships with other sellers in your niche, which leads to more trains, collabs and referrals.
• Momentum. A steady stream of incoming viewers keeps your show’s energy, and your sales, up.

Raid train vs. a single raid

A single raid is a one-time handoff: you end your show and send viewers to one other seller. A raid train is a planned chain of those handoffs, with an agreed order and schedule, so the audience moves through many sellers in one run. The train format is what turns a casual favor into something you can count on every week.

The hard part, and who handles it

The selling is the fun part. Two other things trip trains up.

Keeping everyone on the same lineup. A pinned spreadsheet in a group chat, people unsure who’s next, the order shifting when someone drops. That’s the organizer’s job, and it’s what Raid Train Express is for: a free planner where the organizer builds the lineup and every train gets a live public page with who’s on now and who’s next.

Your own show, in the moment. Knowing when your slot starts while you’re selling, remembering who you raid into, thanking the organizer. That’s the part Backstage handles. Backstage partners with Raid Train Express, so if your Whatnot username is in a train’s lineup, Backstage finds the train on its own. Shortly before your slot, Backstage Live in Chrome and the iPad app show a countdown and who you’re raiding into next, and the iPad app adds a nudge to shout out the organizer. You sell; Backstage keeps track of the train.
