<jats:title>Abstract</jats:title><jats:p>Postsunset equatorial plasma bubble merging is examined using the National Research Laboratory code SAMI3/equatorial spread <jats:italic>F</jats:italic>. It is found that bubbles merge through an “electrostatic reconnection” process. As multiple bubbles develop, the electrostatic potential associated with one bubble can connect with that of a neighboring bubble: this provides a pathway for the low‐density plasma in one bubble to flow into the adjoining bubble and merge with it. Additionally, high‐speed plasma channels (approximately greater than hundreds of meters per second) can develop during the merging process. Optical data is presented of equatorial plasma bubble evolution that suggests bubble merging occurs in the nighttime equatorial ionosphere.</jats:p>
