Meaning
Until the very last moment, when the outcome remains genuinely uncertain right up to the end.
It describes tension rather than mere lateness — the phrase implies a close contest or tight deadline where nobody can be sure of the result until the final second.
Origin
Before photo-finish cameras existed, American racetracks of the late nineteenth century strung a wire above the finish line so track officials could judge, by eye, which horse’s nose crossed it first. An early documented use already treats the image as familiar: “Scribner’s Magazine” described a tight 1889 race in which two horses ran “head and head, passing lapped together under the wire.” A close finish, decided only once the horses reached that wire, naturally extended into a phrase for any contest or deadline whose outcome stays genuinely uncertain until the very last moment. The same finish-line imagery produced two related but distinct phrases still in use today: “wire to wire,” meaning a race led from start to finish without ever being caught, and “under the wire,” meaning at the last possible moment before a cutoff — a useful reminder that “down to the wire” and “under the wire” describe two different things, despite sounding alike.
