Cardi B and Stefon Diggs’ on-again, off-again relationship, marked by a February 2026 split shortly after the Super Bowl and subsequent reconciliations that included a May Mother’s Day event with public PDA, has since cooled without any confirmed proposal or stable commitment. By July, Cardi publicly addressed fans urging her to stay single, stating she had been single during her tour and was not interested in remaining that way indefinitely, while sightings and comments pointed to distance rather than forward momentum toward engagement. Diggs’ earlier remarks that marriage was “on the agenda” have not been followed by further steps, and the pair’s pattern of volatility—coupled with co-parenting their young son amid Cardi’s focus on her album, tour, and personal stability—has led traders to assign an 89% implied probability against a 2026 engagement. No major catalysts, such as renewed public appearances or announcements, have emerged in recent months to shift that consensus.
