We define the stabilizing number of a knot as the minimal number of connected summands required for to bound a null‐homologous locally flat disk in . This quantity is defined when the Arf invariant of is zero. We show that is bounded below by signatures and Casson–Gordon invariants and bounded above by the topological 4‐genus . We provide an infinite family of examples with .
