A WebmasterWorld thread has someone noticing that Google is showing rich snippets under a site but those rich snippets are coming from a different set of sites, not from the listed site's source code.
The search result is for [coldplay], a popular band. The result loads their home page and then what appears to be event rich snippets below the search listing. Here is a picture:

As you can see, the event information is coming from third party sites such as ticketmaster.com, vividseats.com, and others. How did they manage to get listed under a web page for such a popular brand? Is this specifically being pulled from these third party site's rich snippets data? I guess these sites are more trusted than others?
I assume this happens with other rich snippets?

I do SEO for http://seatgeek.com/ so this is a pretty interesting development for me. If this was being pulled by most trustworthy sites, I would expect StubHub over VividSeats as they dominate the event ticketing SERPs among ticket resellers.

It means google trust more trusted sites and will give weight to such sites.

I guess my point, is that it isn't showing the most trusted sites. Seems to be somewhat random, with a clear preference for Ticketmaster (understandable/trusted), Songkick and ticketliquidator. But StubHub is nowhere to be found and easily the most trusted ticketing site in Google's eyes based on my experience.

It should be interesting to see who comes away with more authority in terms of influence for out bound links.

You missed the obvious - the two are not connected. The first result is simply the official coldplay site and the "upcoming events for coldplay" section just happens to have been added right underneath the official result. Google may or may not be receiving financial compensation for the "upcoming events" section but it is certainly not part of a serp result, it's inserted there.
