**Trader consensus heavily favors "No" at 94% implied probability due to the couple's documented relationship volatility throughout 2026.** Cardi B and Stefon Diggs went public in 2025, welcomed a son in November, then faced confirmed breakup reports by February amid trust issues and unfollows on social media. While they showed public affection at a May Mother's Day event and have had periods of closer contact, neither has confirmed a stable reconciliation, and Cardi has discussed her personal life in ways that suggest openness to other possibilities. Diggs' earlier comment that engagement was "on the agenda" came before these complications, and ongoing paternity matters plus the NFL season's demands have kept momentum low. A late-year reconciliation and proposal remains possible given their shared child, but the pattern of instability makes that outcome unlikely before December 31.
