Csizmadia et al. (2019) found a companion star to the WASP-18 system, named WASP-18B which is a probable M6.5V dwarf with ~0.1 M⊙ at 3519 AU distance from the transit host star.
The existence of this companion star was later confirmed by Pearson (2019)
Michel & Mugrauer (2024) have confirmed further this companion.
