Amazon Just Put Vertical Clips Inside Prime Video's CTV Rate Card
Prime Video launched a TikTok-style Clips feed on May 8, 2026, eight days after Netflix rolled out its own vertical feed and two months after Disney+ shipped a feature called Verts. None of the three apps have published a separate rate card for the format. That puts sub-30-second swipeable inventory inside Prime Video's $26 base CPM and Netflix's $20-30 programmatic floor, prices originally set for 30-second pre-rolls in front of NFL games.
This is the part most CTV planners are going to misclassify in their June flights.
Three streamers, ninety-nine days, one mobile shelf
Disney+ went first. The Verts feed rolled out in the U.S. in March 2026 after a CES 2026 announcement, pulling clips from the Disney catalog into a swipe feed inside the mobile app. Netflix followed on April 30, with Clips launching across nine markets in the same release as a redesigned mobile app. Eight days later, Prime Video added Clips on iOS, Android, and Fire tablets, with broader U.S. rollout coming this summer.
Brian Griffin, Prime Video's director of Global Application Experiences, framed Clips as a discovery surface, not an entertainment one: "Clips gives customers a whole new way to browse with short, personalized snippets tailored to their interests." Amazon tested the format internally during NBA season, using sports highlights to seed the recommendation algorithm. The placement is the carousel on the mobile home page. Tap in, and the experience becomes full-screen vertical, with watchlist, share, and rent-or-subscribe controls layered over the clip.
Three apps. Ninety-nine days. All sourced from internal catalogs, all algorithmically personalized, all sitting on the same mobile shelf where users used to scroll movie posters.
None of the three have made a public ad-format announcement for the feed itself. Disney has been quiet. Netflix's investor day messaging was about doubling ad revenue to roughly $6 billion, with vertical inventory mentioned but not separately priced. Prime Video's spokesperson didn't address ads in the launch.
The CPM mismatch nobody on the buy side is asking about
The pricing has a weird gap underneath all of this. Prime Video's self-serve DSP base sits at $26 CPM, with Guaranteed Buy at $34, and direct-buy rates push toward $75 for premium audiences. Netflix's direct buys run $45-65 CPM, programmatic $20-30. Those rates exist because the unit being sold is a 15- to 30-second pre-roll, served to a full-screen TV in a co-viewing context, with high attention scores and lift-style measurement built in.
A vertical clip feed is not that. It's a phone, in one hand, sub-30 seconds of content, with thumb-scroll dismiss behavior baked into the muscle memory of every user under 35. The TikTok and Reels equivalent of that inventory clears at $5 to $12 CPM in most categories. Vertical video inventory in general tends to command 25-40% higher CPMs than standard display, but that's the upside compared to banners, not compared to streaming.
So the auction has a classification problem. If a Prime Video Clips ad is classified as Prime Video CTV inventory, it goes to advertisers paying $26-34 for premium streaming audiences. If it's classified as short-form mobile video, it should clear closer to Reels rates. Until one of the three platforms says which, the pricing default holds, and the default leans toward whatever wrapper the inventory is sold inside. For Clips, that wrapper is the Amazon DSP that already books Prime Video Guaranteed Buys at the higher rate.
The other piece nobody is pricing in is creative aspect ratio. CTV creative is 16:9, designed to fill a TV. A vertical 9:16 clip feed needs vertical-native creative to render correctly. Most agencies don't have that asset for streaming inventory, because nobody asked them to produce it before March. So the early Clips impressions running this summer are going to serve a lot of letterboxed 16:9 spots in a 9:16 feed, and the completion rate on those is going to look exactly like you'd expect.
Three streamers added a TikTok feed and forgot to print a TikTok rate card.
I think the most likely outcome is that Prime Video keeps Clips inventory inside the Amazon DSP wrapper for the first two quarters, because that's where the demand and the data already are. Which means brand advertisers paying CTV CPMs end up with their 30-second hero spot serving against a 12-second pet video, in a feed where viewability standards for the format have not been published yet.
Why your June flights are walking into this blind
I covered the Netflix side of this two weeks back in the Netflix vertical feed breakdown, and the same question lands on Amazon: when a single insertion order can place your spot in front of a couch in a 30-second slot or in front of a thumb in a 6-second swipe, which one are you actually paying for?
On paper, Amazon has the cleanest data position. Prime Video already owns a shopper graph the rest of the streamers don't, which is exactly why Amazon's UK Netflix targeting deal lands May 18 with no independent ID match. That same shopper data on a vertical-feed surface is genuinely valuable. The catch is that valuable inventory at the wrong CPM is still mispriced inventory, and your media-mix model treats them the same.
For agencies running Prime Video buys ahead of Prime Day, the audit takes about 25 minutes. Pull the last 30 days of Amazon DSP placement reports. Filter to mobile only, in-stream position rather than pre-roll. Anything that shows up in mobile in-stream after May 8 is potentially Clips inventory. Compare its completion rate and viewability against the rest of your Prime Video buys. If completion drops below 70%, that is your signal: you are paying CTV rates for content that is being scrolled past.
And to be fair, the 70% threshold is mostly a working number. The format is too new for a clean independent benchmark, and what you really want as a comparison is whatever your own pre-Clips Prime Video baseline was, account by account. Standard CTV completion rates run 92-97% on properly placed pre-roll, so anything dropping into the 60s is loud regardless of where you set the line.
What to push for in your June IO conversations
Three asks for the call with your Amazon rep this month. First, ask directly whether Clips inventory is included in your current Prime Video Guaranteed Buy package. If they say yes, push for a carve-out or a separate rate. If they say no, ask in writing whether it could be included silently in a future flight without a notification. Get that one in email.
Second, request format-level reporting. Position, device, and creative duration breakouts. The fact that the three platforms haven't published rate cards doesn't mean their adtech can't report at the format level. It just means they haven't been asked to in volume.
Third, watch for the rate-card update from Pinterest or Snap that probably comes within roughly 60 days. They've been pitching brand-safe vertical feeds at premium CPMs for over a year, and three new competitors with weaker measurement just walked into their market. Their move will tell you what the actual price of vertical streaming inventory should be. From what I've seen, that's usually how mispricings like this get resolved. Not a public correction. A quiet competitor undercut that everyone notices three quarters later, when the Q4 rate sheets land in upfront emails.
My guess is the first agency that catches the misclassification in its attribution model is also the one that calls Amazon and asks for a credit. Whether they get one is a separate question. Until somebody asks for the breakout, though, the price holds where it is, and the only Clips inventory anyone audits is the inventory their CFO flags on the way back from a Q3 review.
