Substack said in an April 2026 blog post that nearly 100,000 publishers are now earning money on the platform worldwide, including almost 30,000 outside the United States. Millions of newsletters have been started on Substack since it launched, and the company doesn’t publish a running count of how many are still active, so there’s no reliable way to turn that into a precise pass rate.
What is clear from the company’s own numbers is that a small fraction of everyone who starts a newsletter ever earns anything from it.
The instinct is to read that gap as a talent filter: the people who monetize are simply better writers than everyone who doesn’t. The gap has very little to do with writing quality and a great deal to do with a set of skills nobody on the platform is actually teaching alongside it.
The number nobody advertises
Substack’s growth story is told almost entirely in subscriber and revenue milestones — the company said in May 2025 that paid subscriptions across the platform had passed 5 million. The monetization number gets mentioned less often, and for good reason: a Press Gazette analysis, current as of early 2025, found at least 52 newsletters pulling in $500,000 or more a year in subscription revenue, up from 27 two years earlier, while the median paying publication earns far closer to beer money than a living. The distribution isn’t a bell curve. It’s a spike near zero with a long, thin tail.
That monetizing group is also less US-centric than the platform’s press coverage usually suggests — nearly a third of the 100,000 earners are based outside the United States, per Substack’s own figures, a reminder that this isn’t a story about one media market saturating. It’s closer to a global pattern repeating itself on a single platform: a small fraction of entrants figure out the business layer, and the rest publish into a feed that rewards the fraction that already has.
What actually separates the tail from the spike
Writing quality is not evenly distributed either, obviously, but it’s nowhere near as skewed as the earnings are. Plenty of genuinely good writers earn nothing, and plenty of newsletters with unremarkable prose sit comfortably in the paying tier. What differs, consistently, is whether the writer treats the newsletter as a piece of writing or as a small business with a writing-shaped product. A business has a distribution plan: some existing audience, platform, or network the writer is porting subscribers in from, rather than hoping the built-in discovery feed finds them. A business has a sense of leverage: which piece of content, format, or offer will do the most work at the least ongoing cost, instead of treating every issue as a one-off. And a business has an actual model: a reason a subscriber pays monthly rather than just reading the free posts, which has to be designed on purpose rather than assumed into existence because the writing is good enough.
Take leverage specifically, since it’s the vaguest of the three and the easiest to skip past. A writer with leverage has usually identified the one format, thread, or argument in their back catalog that reliably outperforms everything else, and then built a system for feeding new readers toward that piece rather than treating every post as an equally weighted lottery ticket. A writer without it publishes fifty issues of roughly even effort and roughly even reach, wonders why growth is flat, and rarely goes back to ask which three of those fifty actually did the work the other forty-seven didn’t.
The part of the job nobody puts in the syllabus
None of this gets taught anywhere near the writing itself. Substack’s own onboarding is about publishing mechanics: setting up a page, choosing a paywall structure, formatting a post. Writing programs, to the extent they touch newsletters at all, focus on craft. The actual operating knowledge, how to build a distribution channel before you need one, how to identify which 20 percent of your output is doing 80 percent of the growth work, how to price and structure a paid tier so it converts instead of just existing, sits in a completely different body of knowledge that most writers never encounter unless they go looking for it deliberately, usually only after they’ve already stalled out.
This is why so many capable writers describe hitting an identical wall at a similar subscriber count: a few hundred to a couple thousand free readers, built almost entirely on the strength of the writing, followed by a plateau that better writing alone can’t push through. Distribution problems don’t respond to better prose. They respond to distribution work, and most writers have never been shown what that work actually looks like, so they default to writing more and hoping the audience finds them.
Why the gap is likely to widen, not close
If anything, the split between the top tier and everyone else is accelerating rather than narrowing. Consolidation tends to compound: the newsletters with distribution and a working model can afford to invest in more of both, while the ones without either stay exactly where they started, publishing into a feed that increasingly favors accounts that already have momentum. The number of newsletters started on Substack will likely keep climbing, because starting one costs nothing. The number earning real money will keep growing much more slowly, because the actual bottleneck was never the writing pipeline. It was always the business one sitting quietly underneath it, and that part still isn’t being taught to most of the people who need it.
Writing on Substack for reasons that have nothing to do with revenue is a perfectly legitimate use of the platform, and plenty of people do exactly that. The argument here is narrower: anyone specifically hoping the newsletter becomes an income source should stop treating the gap between the earners and everyone else as a mystery, or as proof of a talent they lack. It’s a set of business skills sitting one layer beneath the writing, largely untaught, and very learnable once someone tells you it’s there to learn.
