There are a few other indexes that Kagi’s aggregator mixes in (such as Bing Search) but those haven’t been contributing much in terms of meaningful results. The sheer size of Google’s index still dwarfs all the others, including Bing Search.
So yes, Kagi doesn’t scrape but they pay SERP providers who do.
I believe they are building their own index but targeted towards useful results not included in the others
