There is in fact an X-Prize for AI, and it is general enough that it can apply to safety/alignment, though it's not purely aimed at this. http://ai.xprize.org
www.OpenEth.org is a 'let's build stuff and iterate whilst flailing around slightly as concepts develop' engineering-focussed project for Narrow AI / Smart Contract / Algorithm alignment and proofing, that is competing for this prize.
