According to Wikipedia Bing is only part of the results: “DuckDuckGo’s results are a compilation of “over 400” sources according to itself, including Bing, Yahoo! Search BOSS, Wolfram Alpha, Yandex, and its own web crawler (the DuckDuckBot); but none from Google.”

Sure. But I’d be surprised if Bing wasn’t the primary source. Regardless, the results are pretty good, and I don’t mind the ads it uses.
