Abstract: The properties of binary stars are fundamental for understanding star formation and evolution. Spectroscopic binaries (SB) are genuine binaries that probe short to intermediate orbital periods, shedding light on various stellar evolution pathways. We share recent findings from the Gaia-ESO Survey regarding stellar multiplicity from a statistical point of view. Additionally, we present the binary content of Gaia DR3 and compare Gaia NSS SB with the SB9 reference catalogue of spectroscopic orbits. Finally, we provide insights into the detectability of SB within the context of other large spectroscopic surveys, such as 4MOST, which is set to begin operations next year.
