Substack in 2026: What It Is, Why It’s Surging, and What’s Next
If you still think of Substack as “that newsletter app writers use,” you’ve been left behind. In 2026, Substack is a full publishing platform with video, live audio, a dedicated app, and a discovery engine that puts creators in front of readers who’ve never heard of them. And a growing number of the people building real businesses on it aren’t journalists or novelists — they’re consultants, coaches, agencies, and B2B founders using it as their primary channel for audience, trust, and revenue.
For business owners still weighing whether Substack deserves a place in their marketing stack, the numbers — and the platform’s direction — make a strong case.
What Substack actually is now
Substack launched as a simple idea: let writers publish newsletters and charge for subscriptions directly, without an ad-supported middleman deciding what gets seen. That core model hasn’t changed. What has changed is everything built around it.
Substack is now a multi-format publishing platform. Creators can post long-form writing, short-form Notes (Substack’s answer to a social feed), recorded video, live audio, and — as of early 2026 — video built specifically for television. In January, Substack launched a TV app for Apple TV and Google TV, complete with a “For You” discovery row that surfaces video from creators a viewer has never followed.
In March, it rolled out Recording Studio, a built-in tool for recording solo videos or interviews with up to two guests and publishing them without ever opening a separate editing program.
The result is a platform that looks less like “email newsletter software” and more like a self-contained media company in a box: writing, audio, video, live events, subscriptions, and payments, all under one roof, with the creator keeping the direct relationship with their audience.
Why it’s surging
Substack’s growth has never been stronger.
Substack now has more than 5 million paid subscriptions, up from 4 million in November 2024 — over a million new paid subscriptions added in about four months. Layer in free subscribers and the platform counts more than 20 million monthly active subscribers overall.
Money is following attention. Writers collectively earned $450 million in gross revenue on the platform in 2025, with total payout volume across all creators now exceeding $600 million a year. Nearly 100,000 publications now earn money on Substack, up from 50,000 in May 2025 — the number of monetizing publications doubled in well under a year. More than 40,000 of those are paying creators in a meaningful, sustained way, up from 24,000 in 2023. At the top end, the ten highest-earning publications bring in over $100 million a year between them, and more than 50 publications individually clear $1 million annually.
Investors have taken notice, too: Substack closed a $100 million Series C round led by BOND in July 2025, valuing the company at $1.1 billion.
Behind these numbers is a structural shift in how Substack drives growth. Late in 2025, Substack changed how its Notes feed works — it no longer prioritizes content from people you already follow, meaning most of what appears in a reader’s feed now comes from creators they’ve never encountered before.
Combined with cross-promotion tools and built-in recommendations, this makes Notes the platform’s primary discovery engine, especially for publications still building their first few thousand subscribers. Substack has effectively built its own distribution network, so creators are no longer dependent on external social platforms or search algorithms to find readers.
Why business owners specifically should pay attention
Most of the conversation around Substack still centers on independent writers and journalists. But there’s a quiet revolution happening as more and more business owners join the platform.
It builds a direct, owned relationship with your audience. Every subscriber’s email address belongs to you. There’s no algorithm standing between a business and the people who’ve chosen to hear from it, and no ad platform that can change the rules on reach overnight. For a business, that’s a marketing asset which is fully owned, growing week by week and safe from platform changes.
It monetizes expertise directly. A consultant, agency, or B2B company already has expert knowledge worth paying for. Substack turns that knowledge into a subscription product without needing to build separate payment infrastructure, a membership site, or a course platform — subscriptions, paywalls, and payouts are native to the platform.
It’s where business audiences already are. Lenny’s Newsletter, written for product managers and startup operators, is one of the clearest examples: over 18,000 paying subscribers generating more than $2 million a year, built entirely around practical, business-relevant expertise rather than general-interest writing. It’s proof that a tightly-defined professional audience will pay for a publication that consistently delivers value to their work.
It compounds instead of resetting. Every post adds to a searchable, shareable archive that keeps working long after publication — unlike a social post that has a shelf life measured in hours. For a business building long-term authority in its category, that archive gradually grows into a client-attracting machine.
It’s now a full media channel, not just an email list. With video, live audio, and now a TV app in the mix, a business publication on Substack can function as a lightweight content studio — building the kind of multi-format brand presence that used to require a much bigger production budget.
What’s next
Substack’s own product roadmap points toward more of the same: audio posts and read-alouds, deeper search and discovery, in-app subscription upgrades, and dedicated publication hubs where readers can browse everything a creator has made across formats. The direction is clear — Substack wants to be the place where a creator’s entire body of work lives, in whatever format a reader prefers to consume it, with subscription revenue attached to all of it.
For businesses, that roadmap is an invitation. The tools required to run a credible media presence — publishing, video, live formats, discovery, and monetization — are converging into one platform, lowering the cost of entry for companies that want to build direct audience relationships rather than rent them from ad platforms.
The businesses moving early are the ones building the audience, archive, and revenue stream now, while the opportunity is still relatively uncrowded in most professional categories. The ones who wait will be building the same thing later, against more competition, for a smaller share of attention.
Getting started
None of this requires becoming a full-time creator. It requires a clear strategy: the right niche, a consistent publishing cadence, and a monetization model that fits the business. That’s the part most companies get wrong when they try Substack without a plan — and it’s exactly where a second set of experienced eyes pays for itself.
