The Substackification of Media: 5 Million Paid Subscriptions and the $150M Exit That Validated Everything

2025 was the “Substackification” of media. If 2024 was the year of the podcast, 2025 was the year of the newsletter. Substack reached 5 million paid subscriptions—up 67% year-over-year—and raised $100 million at a $1.1 billion valuation. Competitor Beehiiv grew newsletters 60% to 140,000 and nearly doubled revenue to $28 million.

From Michael Burry sharing AI bubble warnings to Charli XCX chronicling pop stardom, the format has become the default for direct audience relationships.

Legacy Media Is Joining Rather Than Fighting

New York magazine, the New Yorker, WSJ Opinion, and Paris Review all launched Substacks in 2025. Newsweek and Time moved portfolios to Beehiiv. Publishers lost traffic from Facebook and Google’s AI summaries; newsletters offer direct reader connection.

The Economics Work

Tina Brown’s Fresh Hell has 75,000 subscribers and “healthy revenue.” Michael Burry charges up to $379 per year with 76,500 subscribers. Arnold Schwarzenegger’s fitness newsletter has over 1 million subscribers.

The platform economics favor creators: platforms capture 10-14% of subscriber revenue—far better than the App Store’s 30%.

The $150 Million Validation

Paramount paid $150 million for The Free Press, led by Bari Weiss—validating that newsletter-native media companies can reach meaningful scale and exit value. The acquisition proved the model works beyond creator income.

Trust Has Shifted to Individuals

“Audiences trust individual journalists more than established media outlets,” says a former Washington Post creator who left to launch an independent newsletter. The institutional brand matters less than the personal one.

The Platforms Are Expanding

Beehiiv is building website tools and podcast capabilities. Substack is experimenting with advertising sponsorships. Both are evolving from newsletter hosts to full creator infrastructure — as explored in the economics of AI compute infrastructure — .

Newsletters represent the unbundling of media institutions into individual creator businesses. The structural shift favors those who build direct audience relationships over those who depend on platform distribution.
