Let p be a prime number, F a field containing a root of unity of order p, and GF​ the absolute Galois group. Extending results of Hopkins, Wickelgren, Mináč and Tân, we prove that the triple Massey product H1(GF​)3→H2(GF​) contains 0 whenever it is non-empty. This gives a new restriction on the possible profinite group structure of GF​.
