Relationship volatility and repeated public drama have anchored trader sentiment against a 2026 engagement, keeping “No” at 79.1% implied probability. Cardi B and Stefon Diggs went public in 2025 and welcomed a son later that year, but a publicized split near the February 2026 Super Bowl—fueled by trust issues and heated exchanges—has been followed by failed reconciliation attempts, ongoing paternity disputes, social media unfollows, and mixed signals from both sides. Diggs has offered only cautious comments on future plans rather than firm commitment, while the couple’s on-and-off pattern mirrors typical high-profile celebrity relationships lacking stable momentum. With no confirmed proposals, joint appearances, or positive industry buzz through mid-August, traders see insufficient catalysts before year-end to shift consensus.
