Songfacts®:

• "Who Knows" is a song about not knowing; not knowing if you're enough, not knowing what love really means, and not knowing where the future leads.
• Over a sparse acoustic backdrop, Daniel Caesar grapples with self-doubt, feeling unworthy of his love interest's purity and kindness. The chorus offers a shrug of both hope and doubt: "Maybe we get married one day, but who knows?"
• Caesar's unworthiness and overwhelming love in "Who Knows" is framed as a universal experience rather than being tied to a specific known partner. This makes the song a lot more relatable.
• Daniel Caesar co-produced the song with longtime collaborator Matthew Burnett, English singer-songwriter Rex Orange County, and former Brockhampton DJ Romil Hemnani. There were additional writing contributions from songwriter Dylan "Sir Dylan" Wiggins, Sudanese singer-songwriter Mustafa Ahmed, and Bon Iver's Justin Vernon.
• "Who Knows" appears on Caesar's fourth album, Son of Spergy, a record born from reconciliation with his parents, "Spergy" being his father's nickname. In that context, the song sits alongside the album's broader themes of faith, fatherhood, and forgiveness. It's an inward-looking moment on a project that constantly shifts between confession and celebration.
• When Caesar performed the song on The Tonight Show Starring Jimmy Fallon on November 5, 2025, the presentation matched the tone perfectly: just a red beanie, a blue hooded jacket, and an acoustic guitar under a single spotlight. No theatrics, no fireworks, just one man trying to sing his way through the fog of uncertainty.
