Their website says, “Kaleidotrope publishes predominantly speculative fiction and poetry—science fiction, fantasy, and horror, but also compelling work that blurs the lines between these and falls outside of neat genre categories. (Man does not live on space ships, elves, and ghostly ax murderers alone, after all.)” And, “We have no minimum or maximum word count for fiction but strongly prefer stories over 250 words and under 10,000.
We consider all forms of poetry, but individual haiku, or other very short poems, may be a tougher sell.” They will soon open for a brief submission period.
Submission period: 19th to 25th April 2026
Length: See above
Pay: $0.01/word for fiction, $5 for poetry
