Creator economy
Substack is worth $1.1 billion on about $45 million of revenue.
A roughly 24x revenue multiple on a company that takes 10% of what its writers earn. The interesting part is not the headline number — it is what it implies about how the market prices a newsletter business, including yours.
The number: $1.1 billion
Substack raised $100 million in July 2025 in a Series C led by BOND and The Chernin Group, at a post-money valuation of $1.1 billion. That is the current figure, and it is the one to quote until the next round or an IPO changes it.
It roughly doubled the company's previous mark. The 2021 Series B, led by Andreessen Horowitz, valued Substack at $650 million. In between there was a widely-reported down period, a 2023 community round on Wefunder priced at $585 million, and a stretch where the whole newsletter category was assumed to have peaked.
Total funding since the 2017 founding is somewhere around $200 million across seed, Series A, B and C, with Y Combinator, Tiger Global, a16z, BOND and The Chernin Group among the investors. As of mid-2026 the company is privately held and pre-IPO.

- 2021 Series B - $650M valuation, led by Andreessen Horowitz
- 2023 Wefunder community round - priced at $585M
- Roughly $200M raised in total since 2017
- Still private as of 2026; no IPO announced
What is actually underneath it
Substack's own revenue is a 10% cut of what paying subscribers send its writers. That is the whole model, and it makes the business unusually easy to reason about: the company's revenue is a fixed fraction of the creator economy running on top of it.
At the time of the Series C, Substack was running at roughly $45 million in annualised revenue, up from about $37 million in 2024 and $30 million in 2023. Writers on the platform had collectively grossed somewhere near $450 million by early 2025, and there were more than five million active paid subscriptions across the network. The company reported positive cash flow in the first quarter of 2025.
Which means the headline is a roughly 24x forward revenue multiple. That is a growth-software multiple, not a media multiple — and it is the single most interesting fact in this whole story.
Why a 24x multiple, when newsletters sell for 3x
If you sold your own newsletter tomorrow you would not get 24x revenue. Individual newsletters typically change hands somewhere between 2x and 5x annual revenue, occasionally higher for a category-leading list with unusually low churn.
The gap is not unfair; it reflects two genuinely different assets. Substack is priced as infrastructure — recurring revenue across thousands of publications, low churn at the aggregate level because no single writer leaving matters, and revenue that grows without proportional cost. Your newsletter is priced as a small media business whose revenue depends on one person continuing to show up.
That distinction is the useful takeaway. Everything that makes a newsletter valuable to a buyer is a step away from "one person writing" and towards "a system that keeps producing": diversified revenue, low churn, a list that is not dependent on one platform, and content that gets discovered by people who have never heard of the author.
The number that actually affects you
Substack's valuation is trivia unless you hold equity in it. What is not trivia is what your own publication is worth, and that number is calculable rather than mystical.
It comes down to annual recurring revenue, monthly churn, the free-to-paid conversion rate, list growth, and how concentrated your revenue is across a handful of subscribers. Change any one of those and the multiple moves before the revenue does.
We built a calculator for it — put in your subscriber counts, price, and churn, and it gives you a valuation range with the assumptions visible rather than hidden inside a black box.
Is Substack going public?
There is no announced IPO. As of 2026 Substack is a private, venture-backed company that has recently raised, is reporting positive cash flow, and has no obvious pressure to list.
The honest read is that a company at $45 million of revenue is small for a public listing, and the usual expectation is a few more years of compounding first. Treat any specific IPO date you see quoted as speculation — the readiness scores published by pre-IPO tracking sites are models, not information.
For a writer, none of it changes anything day to day. The 10% cut is the 10% cut whether the company is worth $650 million or $1.1 billion.
What actually moves your own number
Growth is the input every valuation model weights hardest, and for a written newsletter the constraint is almost always discovery rather than quality. Good posts do not spread on their own; they need a surface that carries them to people who are not already subscribed.
Video is the most under-used of those surfaces for written-first publishers, because producing it traditionally costs an afternoon per post. Generating it from the post you already wrote changes the arithmetic — a narrated version of an essay becomes a YouTube upload, a LinkedIn post, and an embed on your own site, which is three discovery surfaces for a piece of work you had already finished.
It is the least glamorous growth lever and one of the few that compounds, because every video keeps working long after the email has been archived.

Frequently Asked Questions
How much is Substack worth?
Substack was valued at $1.1 billion after a $100 million Series C in July 2025, led by BOND and The Chernin Group. That roughly doubled its previous $650 million mark from the 2021 Series B led by Andreessen Horowitz. It remains a private company with no announced IPO.
What is Substack's revenue?
Around $45 million in annualised revenue at the time of the 2025 Series C, up from roughly $37 million in 2024 and $30 million in 2023. Substack earns a 10% cut of what paying subscribers pay its writers, so its revenue is a fixed fraction of the creator earnings on the platform — writers had collectively grossed around $450 million by early 2025.
What multiple is Substack valued at?
Roughly 24 times annualised revenue, based on a $1.1 billion valuation against about $45 million of revenue. That is a software multiple rather than a media one, reflecting recurring revenue across thousands of publications rather than dependence on any single writer.
How many paid subscriptions does Substack have?
More than five million active paid subscriptions across the network as of early 2025, with over 50 creators earning more than $1 million a year at the time of the Series C.
Is Substack profitable?
Substack reported positive cash flow in the first quarter of 2025. Positive cash flow is not the same as accounting profitability, and as a private company it does not publish full financials, so treat anything more specific than that as an estimate.
Is Substack going public?
No IPO has been announced. As of 2026 it is private, recently funded, and at a revenue scale that is small for a public listing. Any specific IPO timing you see quoted comes from third-party prediction models rather than from the company.
How much is my own Substack worth?
Individual newsletters typically trade between roughly 2x and 5x annual revenue, well below Substack's own multiple, because the value depends on one person continuing to publish. The main inputs are annual recurring revenue, monthly churn, free-to-paid conversion, growth rate, and revenue concentration. The Substack valuation calculator on this site works through those inputs and shows the assumptions.
