Brilliant, we should set up a page with a list of SPARQL endpoits for Wikidata! For production usage, it is great to have a variety to chose from.
==WARNING==
The RDF format is currently in flux. The purpose of the Chilean endpoint http://milenio.dcc.uchile.cl/sparql is to gather feedback that helps us how to possibly the RDF structure for greater utility/simplicity. There will be several updates to the format in the net few weeks. Please help us to find out what is needed by also testing at http://milenio.dcc.uchile.cl/sparql. We gather query logs and are happy to share them. This said, please also tell us if other endpoints work better/differently/worse for you. Any feedback is welcome.
Cheers,
Markus

Hi everyone,
I'd just like to announce another experimental Wikidata SPARQL endpoint [1], kindly provided by the folks at SpazioDati [2].
It contains both the simplified and the complete dumps, as per [3]. Each dump file is stored under a different named graph. We are collecting the query logs, and will share the most frequent queries.
Cheers!

Dear all,
Thanks to the people at the Center of Semantic Web Research in Chile [1], we have a very first public SPARQL endpoint for Wikidata running. This is very preliminary, so do not rely on it in applications and expect things to fail, but you may still enjoy some things.
You have a SPARQL that provides access to Wikidata dumps loaded into an RDF compliant RDBMS (in this case a Virtuoso RDBMS instance). I emphasis "a" because "the first" isn't accurate.
There are other endpoints that provide access to Wikidata dumps:
[1]http://lod.openlinksw.com/sparql -- 61 Billion+ RDF triples culled from across the LOD Cloud (if you lookup Wikidata URIs that are objects of owl:sameAs relations you'll end up in Wikidata own Linked Data Space)
[2]http://wikidata.metaphacts.com/sparql -- another endpoint I discovered yesterday .
