Substack Creator Exodus: Platform Tax Drives Top Writers to Flee En Masse

Why the Once-Star Platform Can't Retain Its Top Creators

Substack, the Newsletter platform that once dominated the creator economy wave, is experiencing a notable creator exodus. An increasing number of prominent writers are choosing to leave Substack for competitors most people have never heard of. Behind this migration lies creators' growing frustration with the platform's commission model—what insiders call the "Substack tax."

Substack was founded in 2017 by Chris Best, Hamish McKenzie, and Jairaj Sethi, with the core vision of making it easy for anyone to create paid Newsletters (email publications). The platform experienced explosive growth in 2020-2021, closely tied to two factors: first, the massive layoffs at traditional media outlets during the COVID-19 pandemic, which left many veteran journalists and columnists seeking new income streams; and second, the rise of the "Creator Economy" concept—referring to the economic model where individual creators provide content directly to audiences through digital platforms and earn revenue, with the total market estimated at over $100 billion. At its peak, Substack attracted a wide array of well-known writers including political commentators, tech journalists, and novelists, with total paid subscribers on the platform surpassing several million.

Top Creators Lead the Exodus: The Ankler Becomes the Latest Landmark Departure

Last month, one of Substack's most popular publications, The Ankler, announced it was leaving the platform in favor of an alternative that offers more control over its website. The Ankler is a paid newsletter focused on in-depth coverage of Hollywood and the entertainment industry, founded by veteran entertainment journalist Richard Rushfield. Known for its sharp insider analysis and no-holds-barred industry commentary, it's considered essential reading for Hollywood's power circles, with subscription pricing at the high end for newsletters. The Ankler's departure carries symbolic significance because it's not only one of the highest-earning publications on Substack but also represents a category of mature media products that have already completed their brand-building, possess high-net-worth loyal readerships—precisely the type of creators Substack least wants to lose.

The Ankler is not an isolated case. Over the past year, multiple influential creators have made the same choice.

These departing creators have expressed similar demands:

• Greater autonomy and flexible customization capabilities
• More reasonable revenue-sharing models
• Complete control over their own digital assets

Once a creator's subscription revenue reaches a certain scale, Substack's platform commission becomes an impossible-to-ignore "tax." Whether this fee is worth the value received is being questioned by an increasing number of people.

How Much Does the Substack Platform Tax Actually Cost?

Substack's business model is built on taking a percentage commission from creators' paid subscription revenue. Specifically, Substack's fee structure consists of multiple layers: the platform itself takes 10% of paid subscription revenue, and the payment processor Stripe charges approximately 2.9% plus $0.30 per transaction. This means creators actually receive roughly 87% of total subscription revenue.

For writers just starting out, this model genuinely lowers the barrier to entry—you don't need to pay anything upfront, and the platform only charges when you earn money. However, as the subscriber base grows, the absolute amount of this "platform tax" rises accordingly.

Consider a creator with 5,000 paid subscribers each paying $100 per year: out of $500,000 in annual gross revenue, Substack's platform commission alone amounts to $50,000, and total deductions including Stripe fees could approach $70,000. Notably, this proportional model means platform revenue is completely linearly tied to creator revenue—the more successful the creator, the higher the absolute amount paid to the platform, yet the marginal value the platform provides doesn't increase proportionally.

For top creators earning thousands or even tens of thousands of dollars monthly, annual payments to Substack can reach tens of thousands of dollars. Whether what they receive in return—a relatively standardized page template, limited customization options, and the platform's recommendation traffic—is worth that price depends on who you ask.

More critically, once creators have established their own brand and loyal readership, the platform's "discovery" function diminishes significantly in value for them. What they truly need at that point is full autonomy over website design, data ownership, and reader relationship management.

What Are Alternative Platforms Offering to Poach Creators?

This exodus has created a window of opportunity for a batch of emerging Newsletter platforms. While these alternatives are far less well-known than Substack, they offer differentiated advantages across several key dimensions:

• Lower fees or flat-rate pricing models: Instead of taking a percentage of revenue, they charge fixed monthly or annual fees—the higher your revenue, the better the deal
• Stronger customization capabilities: Allowing creators to deeply customize website appearance and functionality to build an independent brand identity
• Complete data ownership: Giving creators full control over subscriber data and email lists, free from platform constraints
• More flexible monetization tools: Supporting advertising, sponsorships, courses, communities, and other revenue streams beyond just paid subscriptions

The main Substack alternatives currently on the market include Ghost, Beehiiv, ConvertKit (now rebranded as Kit), Buttondown, and others. Ghost is an open-source content management system that uses a flat monthly fee model (starting at $9/month), takes zero revenue share, and allows creators to fully self-host—meaning they can run the entire platform on their own servers. Beehiiv is known for its powerful growth tools and advertising monetization capabilities, offering both free and fixed paid tiers. ConvertKit/Kit originated in the email marketing space and has deep expertise in automation workflows and audience segmentation. The common thread among these platforms is that they treat newsletters as part of the creator's own infrastructure rather than an appendage of a platform ecosystem.

For creators whose annual revenue exceeds a certain threshold, the cost savings from switching to a flat-rate platform are substantial. For a creator earning $500,000 annually, switching from Substack to a flat-rate platform like Ghost can save tens of thousands of dollars per year—the math isn't hard to do.

The Perennial Problem of the Creator Economy: The Platform-Creator Power Struggle

This phenomenon reflects a recurring structural contradiction in the creator economy: the power struggle between platforms and creators.

Every content platform faces the same dilemma—they need favorable terms to attract creators early on, but when the platform needs to become profitable, the commission model inevitably conflicts with the interests of top creators. From YouTube to TikTok, from Spotify to Substack, this story plays out again and again.

This struggle has deep historical precedents in the digital content space. YouTube has maintained a 55/45 ad revenue split with creators since 2007 (creators get 55%), a ratio unchanged for over a decade, yet opaque adjustments to recommendation algorithms have repeatedly sparked creator discontent. Spotify's streaming revenue model is more complex, using a "pro-rata" rather than "user-centric" calculation method, resulting in extremely low income for small and mid-sized musicians. TikTok's Creator Fund, with its fixed pool and ever-increasing participants, has led to continuously declining per-unit earnings. In economic terms, this phenomenon can be explained by "platform lock-in effects": platforms retain creators within their ecosystem through network effects and switching costs, but when the switching costs of alternatives drop below a certain threshold, top creators are the first to "unlock" and leave because their opportunity costs are highest.

The pattern is clear: A platform's value lies in helping creators go from zero to one, but in the journey from one to one hundred, platforms often transform from enablers into burdens. Once top creators possess sufficient influence and loyal audiences, they seek greater independence.

For Substack, how to retain core creators while maintaining commercial sustainability is an urgent challenge. If the continued loss of top creators creates a demonstration effect, it could shake the confidence of mid-tier creators in the platform, ultimately affecting the health of the entire ecosystem.

The Creator Consensus: Own Your Own Infrastructure

The exodus triggered by the "Substack tax" is essentially a collective reassessment by creators of their dependency relationship with platforms.

Creators' demands for data ownership involve more than just the ability to export an email list—they touch on the deeper issue of "digital sovereignty." Under the Substack model, while creators can theoretically export subscribers' email addresses, deeper data such as reading behavior, interaction preferences, and paid conversion paths remain in the platform's hands. More importantly, when a creator's content distribution depends on the platform's recommendation algorithm and in-app reading experience, the platform effectively controls the "middle layer" between creator and reader. This aligns with the Web3 movement's advocacy for "Decentralized Identity" (DID) and "portable social graphs"—the core argument being that users (including creators) should own their own digital relationships and data assets rather than entrusting them to any single platform.

In today's increasingly mature creator economy, owning your own infrastructure and controlling your own audience relationships is becoming the consensus among more and more professional creators. This isn't just a story about competition between Newsletter platforms—it's a microcosm of the entire creator economy maturing. True independence begins with not depending on any single platform.

Key Takeaways

• The core reason for the exodus is dissatisfaction with the platform's commission model (the "Substack tax") and the desire for greater autonomous control
• Emerging competitors (such as Ghost, Beehiiv, Kit, etc.) attract departing creators through differentiated advantages including lower fees, stronger customization capabilities, and data ownership
• This phenomenon reflects the recurring power struggle between platforms and top creators in the creator economy, highly similar to historical experiences with YouTube, Spotify, TikTok, and other platforms
• The continued loss of top creators could produce a demonstration effect that poses a long-term threat to Substack's overall ecosystem, while also driving the entire creator economy toward "digital sovereignty"
