Top trending newsletters on Substack: September 27
Steve Kim - Korean Cosell
Boxing reporter newsletter still at rank 1. Kim's September 25, 2026 post said Fury-Joshua was set for December 11, 2026 at Principality Stadium in Cardiff, Wales, on Netflix. That fight date is the clearest same-week hook for the hold at rank 1.
Josh Appelbaum
Sports-betting analyst, new at rank 2. VSiN lists Appelbaum as a 2019-era contributor and author of The Everything Guide to Sports Betting. A college-football Saturday is a plausible traffic day for a betting writer.

What today's Substack trends reveal
The September 27 Substack ten tilted toward sports writing. Steve Kim's boxing note on Fury-Joshua for December 11 keeps rank 1, and Appelbaum plus Lombardi add betting and NFL voices at 2 and 6. AI Investment Brief's fall from 2 to 9 is the sharpest demotion, so the board is not an AI-investing day. Craft and luxury titles remain in the ten but no longer occupy the top three.
