Substack adds a podcast tab and says creators earn $200 million a year

Substack’s iOS and Android app now has a dedicated podcast tab that lists shows published by Substack creators, and the company says those creators collectively earn more than $200 million a year. Its showcase launch, Shea Serrano’s new show Organizing Things, picked up 120 new paid subscribers in its first week.

Announcing the change on September 11, the company described the tab as “a dedicated space where you can easily reach your existing listeners, and help new listeners find you”. It turns the newsletter platform into something it has not been until now: a place where you go looking for shows. On its own that is a modest product update, so the revenue claim attached to it deserves a closer look. Substack says the $200 million comes from readers paying for subscriptions rather than from advertisers buying inventory. In the same week, Spotify’s Megaphone quietly made it harder for a new show to reach its advertising network at all. Two platforms moved in opposite directions on the same question: how soon, and by what route, does a new podcast start earning?

A podcast tab, plus text-to-speech on almost every post

The tab does two jobs. It gives subscribers an inbox for the shows they already pay for or follow, separating audio from the flood of posts in the main feed. And it surfaces other Substack shows to people browsing, which is the part creators care about. Substack also switched on text-to-speech for almost all posts, so a written piece can be listened to whether or not the author records anything. That is a separate feature, and worth keeping separate: synthetic narration of a written post is a different product from a podcast.

The tab is a closed list. It does not index the wider podcast world the way Apple Podcasts, Spotify or the Podcast Index do. We think this is a deliberate trade: a smaller catalog, but one where every listing has a payment relationship already attached. Substack is building a shop window inside a place where people are already used to handing over a card, and has no need to win the app war to do it.

Substack’s $200 million figure is unaudited

The $200 million a year is a company statement, given by Substack to the trade press. It has not been audited by a third party, and Substack has published no breakdown of it. That does not make it wrong, but it does mean it should be read as a claim rather than a measured figure.

The mix inside that total matters most. In our view the number blends two different things: publications that are genuinely podcasts with a paywall, and newsletters that attach an audio version of a written post. If that is right, the $200 million is subscription money that touches audio, a different thing from podcast revenue in the sense an ad network would use the phrase. Substack has not said how the split falls, and until it does, the fair description is that a large amount of subscription money touches audio on the platform.

What is checkable is the shape of the top end. Substack keeps a public leaderboard of its best-paid podcast publications, which anyone can read without a login. It is heavy on politics, culture and media commentary, the same territory as many of the best technology podcasts that grew out of newsletters and blogs in the first place.

Subscription money also behaves differently from advertising money, and that difference is Substack’s main argument. There is no CPM cycle, no seasonal ad market, no ad load to negotiate and no measurement dispute. A listener either pays or does not, and the creator sees it the same day.

Organizing Things: 10,385 downloads in week one

Alongside the tab, Substack published first-week numbers for a new show called Organizing Things, co-hosted by the writer Shea Serrano. It reported 10,385 downloads and 126,000 views in week one, “entirely organic, no paid promotion or ad spend”, and 120 new paid subscribers to Serrano’s publication.

Serrano’s own framing, quoted in that post, is the most useful line in the whole announcement: “I only need to add 350 paid subscribers and I feel like I’m coming out okay. All the numbers get adjusted, they get shrunken down to something more manageable, if you can do it on your own.”

That is the arithmetic of a subscription show stated plainly, and it is nothing like the arithmetic of an ad-supported one. But the example needs its caveats attached. Serrano is a five-time New York Times bestselling author who has worked with Amazon and Wondery, and he had roughly 128,000 newsletter subscribers before the first episode existed. Nothing about that is a cold start.

So the lesson here is about conversion. What Substack has demonstrated is that an existing audience can be turned into podcast payers quickly. What it has not demonstrated is that the new tab finds listeners for a show nobody has heard of, and that is the claim creators will want tested over the next few months. Serrano’s setup is also open to other apps: free previews go out across Substack, YouTube, Spotify and Apple Podcasts, with full episodes behind the paywall. The free tier is the marketing; the platform is the till.

The same week, the advertising route got narrower

According to reporting by Podnews on September 11, Spotify’s Megaphone changed the qualification rules for the Spotify Audience Network on September 8. A show now needs at least three published episodes before it can be submitted to SPAN, where previously one was enough. This is trade reporting, not an announcement: the change is undocumented, and Spotify has not responded to requests for comment on it.

If the reporting is accurate, the effect falls hardest on limited-run series. One creator who publishes them told Podnews that “having to wait to monetize halfway through the run is pretty debilitating”, which for an eight-part show is fair. A trailer plus a first episode used to be enough to switch the money on.

Put the two changes side by side and the week reads as a straightforward contrast. One platform opened a surface where a new show can be paid on day one by people who already pay for something else. The other pushed the start of ad revenue back by two episodes without telling anyone. Spread across thousands of small shows, that makes a subscription-first launch a cash-flow decision as much as an ideological one.

The industry also has an unsolved timing problem. Magellan AI’s Q2 2026 podcast measurement benchmark report found that only 41% of the site visits generated by a podcast ad campaign arrive in the first week, and 76% by the end of the first month. Ad money is slow to prove itself. Subscription money shows up in a dashboard the afternoon someone clicks subscribe, and for a creator without a finance department that difference counts.

A few hundred payers versus tens of thousands of downloads

The practical comparison is a question of audience size. A subscription podcast can work with a few hundred committed payers. An ad-supported one generally cannot get sponsors interested below tens of thousands of downloads an episode. A weekly show in the mold of the best politics podcasts, with two thousand people paying a few dollars a month, is a real business on Substack and close to invisible to an ad network.

The cost is reach. A closed tab only finds people who already use Substack, while RSS and YouTube reach everyone. Most creators will probably treat it as an extra storefront and keep their main home elsewhere, with the free feed open as Serrano has it, because the platform that collects the money and the platform that finds the audience no longer need to be the same one.

Substack has left two questions open. It has not said whether the tab will carry editorial curation or advertising of its own, which would change how much a listing is worth. And it has not said whether shows hosted elsewhere will ever appear in it, which would change what the tab is altogether.

The leaderboard is the thing to watch. If the same publications sit at the top of it in six months, the tab will have been a convenience for people who were already paying. If new names climb it, Substack will have built the first genuinely subscription-native podcast directory, a competitor for the platforms that treat audio as inventory. Because the leaderboard needs no login, anyone weighing a subscription launch can check it before choosing a route.
