TL;DR: GoodAI launched the Solving the AI Race round of the General AI Challenge. $15,000 in prizes are available for entering suggestions on how to mitigate the risks associated with a race to transformative AI.

They will be accepting submissions until 18 May 2018, and are asking participants to come up with detailed proposals of how to avoid AI research becoming a race where:

• Key stakeholders, including developers, may ignore or underestimate safety procedures, or agreements, in favor of faster utilization
• The fruits of the technology might not be shared by the majority of people to benefit humanity, but only by a selected few
