Spot ad buying is the fastest route into podcast advertising because it skips the negotiation. You pick inventory, pay a published price, and the campaign runs. The best spot ad buying for podcasters usually means one of two jobs: buying placements to promote your own show, or buying placements on behalf of a brand. The six platforms below cover both, and every price and minimum here comes from the platform's own published pages.
Most of these are in the spot-ad buying directory we maintain. This piece adds what each one actually costs to start and who it locks out.
How we picked these
Three things mattered. The platform has to publish a price or a minimum, so you can plan a budget before you talk to anyone. It has to be genuinely self-serve, meaning you can launch without a sales call. And it has to still be operating, which turned out to disqualify less than you would expect but reorder the list considerably.
We have not ranked these by quality, because they do different jobs. A platform that sells you listeners inside a podcast app is not competing with one that sells a brand 500,000 impressions across a network.
1. Spotify Ads Manager
Spotify's self-serve platform sells podcast inventory alongside its music ad formats, and Spotify documents podcast ads as available to advertisers worldwide through Ads Manager, in open beta across 14 markets including the US, UK, Canada, Australia, Germany, France, and Japan.
The published minimum budget starts at $250 for the platform generally, with podcast campaigns documented from $500 per campaign. Spotify advertises fixed CPM pricing, not an auction, which makes the budget arithmetic predictable. Targeting covers podcast categories, age, gender, geography, and sensitive-topic exclusions.
Who it fits: a brand or a show with a real budget that wants reach across many podcasts rather than association with one. The trade-off is that these are produced spots dropped into a stream, so you get none of the host credibility that makes host-read advertising work.
2. Acast
Acast runs both a self-serve ad platform and a managed service. The self-serve side lets you plan and launch campaigns yourself, including sponsorships and targeted pre-recorded ads, with measurement dashboards included. Acast states that campaigns start from as little as $500 on the ad platform.
The format range is wider than most self-serve tools. Acast lists host-read sponsorships, dynamically inserted targeted ads, 30-second spots, full branded episodes, and extensions into social and live events through the managed route.
Best for a buyer who wants host-read inventory without building relationships show by show, and who can clear $500. Anything involving a branded episode or a live extension runs through the managed team rather than the self-serve platform.
3. Gumball
Gumball is a host-read marketplace built by Headgum, the comedy podcast network. Buyers browse shows, see pricing up front, filter by demographics, and book host-read reads across several podcasts in one transaction. Category exclusivity controls are part of the product. Gumball has also extended the marketplace to YouTube creators.
The number that matters if you want to sell, not buy: Gumball requires a show to have at least 10,000 downloads before it can list inventory. Gumball's stated reason is that below that size an advertiser cannot read the result of a single read with any confidence, which is a fair description of the statistics rather than a snub.
Buyers get host-read credibility at marketplace speed. Shows past 10,000 downloads get a sales channel they do not have to staff.
4. Overcast
Overcast is the odd one here, and the most useful for a small show. It sells promotion for your podcast inside the Overcast app itself, below the controls on the Now Playing screen and in the Add Podcast directory. Tapping the ad opens a native view of your episodes with one-tap subscribe.
Pricing is published per category for a 30-day run, from $150 for Leisure up to $1,650 for all categories, in US dollars. Purchase is self-serve by credit card, first come first served, and categories sell out. Approval usually takes about 24 hours. All sales are final.
The rules are strict and worth reading before you plan a campaign. Overcast requires content appropriate for a general audience of all ages, and does not accept gender-specific, region-specific, or non-English podcast ads. Investment advice, sexual content, weapons, drugs, divisive politics, and unsubstantiated claims are all prohibited.
Who it fits: an English-language show with a general-audience premise that wants new subscribers rather than impressions. At $150 this is the one experiment on the list that a show earning nothing can still run. Our guide to podcast advertising on a small budget covers how to judge whether the spend returned anything.
5. AdBarker
AdBarker sits on the other side of the transaction from most of this list. It is a podcast manager with batch audio editing that attaches and swaps ads inside your episodes, with pre-roll, mid-roll, and post-roll placements. Setup runs from an RSS feed.
Pricing is a subscription, not a CPM, from $5 to $79 per month depending on how many shows you run and your download volume, covering 1,000 to 100,000 monthly downloads. Additional downloads cost $49 per month per 100,000. The campaign tooling supports category-based campaigns, date restrictions, download caps, and multi-podcast campaigns.
This is for a network or a podcaster running several shows who needs to insert and rotate their own ads, including cross-promotion between them. At $5 a month it is the cheapest way on this list to run coordinated promos across a slate you already control.
6. Podcorn, and where it went
Podcorn ran as a marketplace connecting brands with podcasters for sponsored content. The podcorn.com domain now returns a 301 redirect to Audacy's creator platform, so it is no longer a standalone destination you can sign up for.
It stays on this list because old roundups still send people there, and knowing a link is a redirect saves you the afternoon. If you were planning around Podcorn, treat Gumball and Acast as the live equivalents.
The published numbers side by side
| Platform | What you buy | Published entry price | Gate |
|---|---|---|---|
| Spotify Ads Manager | Produced spots across Spotify podcast inventory | $500 per podcast campaign | 14 open-beta markets |
| Acast | Host-read, spots, branded episodes | $500 per campaign | None stated for self-serve |

| Overcast | In-app promotion for your own show | $150 for 30 days (Leisure) | English, general audience |
| AdBarker | Ad insertion across your own shows | $5 per month | Download tier |

Treat every figure as the floor you plan against, then confirm it in the checkout before you commit budget.
Buying a spot is not the same as pricing one
If you are on the selling side of this, the published buy-side prices above are a useful sanity check on your own rate card. A brand that can buy a fixed-CPM spot from Spotify has an alternative to your show, and your rate has to be defensible against it. What podcast CPM means breaks down how that number is built, and the sponsorship marketplaces roundup covers the sell-side platforms and their download floors.
The one thing every platform here assumes is that you can say who listens to your show. Spotify's targeting, Gumball's demographic filters, and any direct deal you negotiate all run on audience data you either have or do not.

FAQ
What is spot ad buying in podcasting?
Spot ad buying means purchasing a defined set of ad placements, usually priced on a CPM or a flat campaign fee, instead of negotiating an ongoing sponsorship with one show. You pick the inventory, pay up front, and the campaign runs for a set period or impression count.
What is the cheapest way to buy podcast ad spots?
Overcast publishes the lowest entry price of the platforms here, starting at $150 for a 30-day placement in its Leisure category. Spotify Ads Manager and Acast both start their self-serve platforms at a $500 campaign budget.
Can a small podcast sell spot ads through these platforms?
Selling is harder than buying. Gumball requires 10,000 downloads before a show can list host-read inventory. If your show is below that, you are better off buying promotion for your own show and selling direct to sponsors until you clear the floor.
