Teams that won championships in the European Le Mans Series (ELMS), Asian Le Mans Series (ALMS) and GT World Challenge Europe's (GTWCE) combined Endurance and Sprint Bronze Cup championships received automatic invitations. The 2023 ELMS LMP2 championship runner-up also received an automatic invitation. All current WEC full-season entries were automatically invited. The ACO selected three IMSA SportsCar Championship (IMSA) participants as automatic entries, with one invited to the Hypercar category at IMSA's discretion and the other two to the LMP2 and LMGTE classes. The ELMS LMGTE team that earned automatic entry could only enter in LMGT3 while its LMP3 champion had to enter an LMP2 car.
