About

I’m Aaron Harme, and I write Bitter Fool. I cover sports betting, prediction markets and the business around sports: media rights, team sales, league economics and stadium deals. I also follow AI, tech, markets and crypto wherever the money in those stories is moving.

Bitter Fool comes in two formats. The morning Brief walks through the day’s most important items with my take on each one. Longer pieces stay with a single story, start with the news, and get to my read once the facts are on the table.

Every quote and reported number on this site comes from a named source, and any number I work out myself is built from those. Each source gets a link the first time it appears. I don’t make betting predictions or picks.
