Google earn more per 1000 searches than Bing by quite a margin (I believe there is a stat for this in the UK CMA report). Google can offer an amount greater that any other search engine would find profitable. If I remember correctly, Google earn around double per 1000 searches than Bing does. Other English based indexes tend to use Bing ads and earn even less per 1000 searches. I suspect the amount Google offers is an amount that is deliberately at a level that Bing would not be able to match.
