The biggest brands in podcast advertising just had their best month since March. According to Podscribe estimates reported by Inside Radio, the top 10 podcast advertisers spent a combined $41.1 million in September, up 20.9% on August. July was the low point of the year. September is the sharpest bounce since.
These are US figures, and the US is where podcast advertising gets measured first. But the direction of travel matters to anyone in the UK with a company podcast, or thinking about starting one, because it says something simple: the money that pays for shows is growing again, and it is coming from some new places.
Who spent what
Mint Mobile held the top spot for a second month on roughly $5.2 million, with Quince second on $4.9 million, although both spent a little less than in August. The movement was further down the table.
- PrizePicks jumped 64% to $4.7 million, climbing from ninth to third. It ran on 539 shows, and 92% of its ads were read by the host.
- ChatGPT rose from $3.0 million to $4.0 million and moved into sixth place. It ran across 1,053 shows, and only 12% of its ads were host reads.
- Shopify added 5% to reach $4.5 million and fourth place.
- BetterHelp slipped 10% to $4.4 million, still on 775 shows.
- Amazon fell 59% to $3.1 million, dropping from fourth to ninth.
The risers tell you where the money is coming from
Podscribe also tracks the advertisers growing fastest. Four of the ten biggest risers in September were sports betting, fantasy sports or prediction market companies, and between them they spent an estimated $9.8 million. Polymarket’s spend went up more than ninefold. Taco Bell went from almost nothing to $1.3 million across 1,021 shows in a single month.
Not all of these will be on UK feeds, and some of them never should be. The point is the pattern. When new categories arrive with real budgets, the market for good shows gets deeper, and that is good news for anyone making one.
What it means if your company has a podcast
Most corporate podcasts are still budgeted as a marketing cost. Something you pay for, hope works, and quietly review at the end of the year. A rising ad market is a reason to look at it differently.
A show that builds a loyal audience is an asset with a value of its own. It can carry sponsorship, whether that is a partner brand, a supplier or a sister business. It can be a reach channel you own rather than rent. Either way, the value builds over time, which is exactly why the one-off episode is the weakest way to do it.
Advertisers buy audiences, and audiences come from consistency. The same day, the same look, the same quality, episode after episode. That is why we plan podcasts as seasons rather than single recordings. A season gives listeners a reason to subscribe, gives you enough episodes to learn what works, and gives anyone who might sponsor the show something worth backing.
The AI brands are a market in their own right
ChatGPT going from $3 million to $4 million in a month, across more than a thousand shows, is a signal worth noticing. An AI company is now one of the six biggest buyers of podcast audiences, and it is buying broadly: mostly produced spots rather than host reads from a few hand-picked presenters.
They are also selling products that make more sense when you can see them working. That points towards video: shows filmed properly, with clips cut for social, not just an audio file and a static cover. If you make a show about technology, business or the future of work, the brands with the most to spend are increasingly the ones best matched to you, and they will expect it to look the part.
What we would do now
- Plan a season, not an episode. Eight to twelve episodes on a fixed schedule gives a show the room to build an audience worth reaching.
- Film it. Video podcasts travel further on YouTube and social, and they suit advertisers whose products need to be seen to be understood.
- Measure from day one. Downloads, views, completion and where listeners come from. If a sponsor ever asks what your audience looks like, you want an answer ready.
- Know who you would approach. Make a short list of brands who already buy podcast audiences in your space, and the partners in your own network who would value your listeners.
The market has turned up. The shows that benefit will be the ones already in production, already consistent and already looking like television when the budgets arrive.
