I don't know, Brave says it's every third new tab. https://brave.com/brave-ads/browser/
Looks like I'm getting a ProtonMail ad every few new tabs. I never noticed because I've never looked at the new tab page. Doesn't noticeably slow it down to have the ad there, luckily.
The new tab ads can be disabled with 2 clicks.
