History
Lightspeed was started by publisher Sean Wallace of Prime Books with John Joseph Adams as editor. Wallace also published  Fantasy Magazine. Adams also started to edit Fantasy Magazine from March 2011. Lightspeed became an SFWA-qualifying market in July 2011.

In November of 2011 Adams purchased Lightspeed and Fantasy Magazine from Wallace. From January 2012 issue, both magazines were combined with the name Lightspeed. Fantasy Magazine stopped publishing. The Fantasy Magazine staff was also absorbed into Lightspeed.

In September 2013, Lightspeed published their first Special Issue. It was called "Women Destroy Science Fiction", an anthology entirely written and edited by women. Lightspeed got $53,136 from a Kickstarter to pay for the special issue. This was much more than their goal of $5,000. The additional funds allowed Lightspeed to publish further volumes, entitled "Women Destroy Fantasy" and "Women Destroy Horror."
