Strange Horizons will have three open fiction submissions throughout 2025:

• General Submissions: April 16th at 9 a.m. UTC with a 1,000 story cap
• Novelette Submissions: June 4th at 9 a.m. UTC with a 300 story cap*
• Indigenous Author Submissions: November 3rd at 9 a.m. UTC with a 500 story cap

Once we reach the caps on these open submissions, we’ll close our portal while we work through the submissions. If our portal is open, we are still accepting stories, but once it is closed, please do not send us your work.

Please see our fiction submission guidelines for more details on how to submit once we open and what we publish. Since we are using a story caps, we encourage authors to submit promptly!

All submissions submitted during our last open submission period will be responded and decided on before the open submission in April. We will post more information on our novelette and indigenous author submissions at a later date.

*For our novelette submissions, we will be open to stories between 10,000 and 18,000 words.
