How Substack and Medium actually differ in 2026
Substack is a publishing platform with built-in newsletter, podcast, and chat functionality. Your readers subscribe directly to you. When you publish, the article lands in their email inbox and appears in the Substack app feed. You own the subscriber relationship and can export your list at any time.
Medium is a social blogging platform with an extensive internal audience. Your articles live on medium.com, which has a 94 domain rating that helps articles rank in Google search. Discovery happens through Medium's curation algorithm, topic feeds, and publications. Readers pay Medium a membership fee, and writers earn from a shared revenue pool based on member read time.
The fundamental tradeoff: Medium gives you discovery through its algorithm and search traffic, but you do not own the audience relationship. Substack gives you a direct subscriber list with email delivery, but discovery depends more on your own promotion effort. In 2025, 32 million new subscribers came from within the Substack app itself, showing that Substack's internal discovery is growing rapidly.
