Heat coconut oil in a large pot over high heat. Drop 3 popcorn kernels into hot oil and place a lid on the pot; cook until 1 kernel has popped. Remove the lid and pour in remaining popcorn. Return the lid to the pot and cook popcorn, shaking the pot back and forth over the burner, until there are 1 to 2 seconds between pops, about 5 minutes.

Quickly transfer popcorn to a large bowl; evenly drizzle honey over popcorn. Add salt and cinnamon; toss popcorn with your hands to coat evenly.
