After initially planning the first launches earlier this year, Amazon has now announced that the first full launch for Project Kuiper will take place in the fourth quarter of 2024: https://www.satellitetoday.com/connectivity/2024/06/27/amazon-pushes-the-first-full-kuiper-launch-to-q4/

This market covers a launch attempt. An unsuccessful deployment, including one caused by a launch vehicle failure, still counts as an attempt, and will resolve to yes.

Any postponement beyond January 1st caused by a payload delay, a launch vehicle delay, or a launch scrub will resolve to no.
