IPEDS releases completions data annually. While IPEDS does not have a release schedule or predictable release target, they generally release completions data sometime during the summer. Lightcast incorporates IPEDS' completions data into the next Lightcast datarun, typically the Q4 datarun published in September/early October.
Note: due to the survey nature of IPEDS data, completion data takes approximately a year to be finalized. For example:
2021 Completions released in the 2022.4 datarun (Fall 2022)
