Elon Musk took to X to share GIFs from the movie "Step Brothers," comparing himself and fellow billionaire Jeff Bezos to the film's two main characters after Bezos's space company, Blue Origin, successfully launched its first rocket into orbit.

Elon Musk and Jeff Bezos, two tech moguls who have spent years battling it out for supremacy in the space race, seem to have buried the hatchet—at least, publicly. Their friendly exchange on social media following the results of their respective rocket launches marks a possible end to their long-standing rivalry.

Blue Origin's New Glenn finally roared into orbit in the early hours of Thursday, with SpaceX's Starship rocket set to launch hours later.
