I think they absolutely benefit from being niche, but there are a few other things they have going for them that won't go away if they become popular:
* They're not ad funded. Sergey Brin and Larry Page called this out in 1998 and it is just as true as ever: you need the economics to align. Kagi wins if people keep paying for it. Google wins if you click on Search ads or if you visit a page filled with their non-Search ads.
* Partially because of the economic alignment, Kagi has robust features for customizing your search results. The classic example is that you can block Pinterest, but it also allows gentler up- and down-weights. I have Wikipedia get a boost whenever its results are relevant, which is by itself a huge improvement over Google lately. Meanwhile, I don't see Fandom wikis unless there's absolutely nothing else.
I hope to see more innovation from Kagi in the customization side of things, because I think that's what's going to make the biggest difference in preventing SEO gaming. If users can react instantly to block your site because it's filled with garbage, then it won't matter as much if you find a brief exploit that gets you into the first page of the natural search results. On Google Fandom is impossible to avoid. On Kagi it just takes one click.
