It's everywhere on YouTube, usually as a 'hidden' ad in the alt-right manosphere (e.g. the recent Nick Shirley video he wears a sweatshirt for a gambling site throughout, with constant name drops of it that aren't over ads).

Disgusting behavior, especially coming from those who often claim their content is to improve things. Hypocrites across the board.

I see Kalshi promoted on many sports highlights videos on YouTube.
