This market resolves to the bucket containing the year in which there is credible evidence of an organism with a gene drive being released into a wild population, with the intent to have it spread across the majority of that organisms natural range.  

I do not require it to be released by a government or NGO, a rogue scientist eradicating Malaria/WNV carrying mosquitoes with one would totally count.

I may update the resolution criteria to better fit what I understand the spirit of the market to be.  I will not bet in this market.
