11% — Will Dwayne “The Rock” Johnson be on Jimmy Kimmel Live! before 2027 Kalshi 11% · 16 contracts · $518 volume · medium confidence Updated 2026-08-10 15:39:56 UTC Why this matters: This contract estimates a 14% chance that Dwayne Johnson will appear on Jimmy Kimmel Live! between now and December 31, 2026—approximately six months away. The low probability reflects that Johnson has limited recent history with late-night talk show appearances compared to other major celebrities. The main factors affecting this estimate are Johnson's current project schedule and promotional commitments, which typically drive talk show appearances. His probability sits notably below comparable entertainment figures like Tom Holland (57%), suggesting either less active promotion planned or fewer film/project launches requiring media appearances in this timeframe. The resolution depends entirely on whether an episode airs with Johnson as a guest before year-end. Given the compressed six-month window and Johnson's selective media schedule, the low probability primarily reflects limited scheduled projects requiring traditional late-night promotion rather than any personal factors. Key factors: - No major theatrical film releases or projects with confirmed Johnson involvement have announced premiere dates or promotional campaigns requiring late-night talk show appearances before December 2026 - Johnson has appeared on Jimmy Kimmel Live! previously, establishing precedent but not a regular pattern like younger actors with active film slates - The contract probability of 14% is substantially lower than Tom Holland's 57%, indicating market assessment that Johnson has fewer media commitments or different promotional strategies than peer actors - Six months remains sufficient time for a single appearance if a project launch occurs, but Johnson's selective public schedule makes such appearances less frequent than other A-list celebrities - The year-end deadline creates urgency; any major project announcement or promotional tour launching after October 2026 would effectively reduce likelihood of resolution before 2027 Contracts: - Will Timothée Chalamet be on Jimmy Kimmel Live! before 2027?: Timothée Chalamet — 40¢ Kalshi $293 (weight 57%) - Will Christopher Nolan be on Jimmy Kimmel Live! before 2027?: Christopher Nolan — 9¢ Kalshi $225 (weight 43%) - Will Ariana Grande be on Jimmy Kimmel Live! before 2027?: Ariana Grande — 16¢ Kalshi $0 (weight 0%) - Will Bad Bunny be on Jimmy Kimmel Live! before 2027?: Bad Bunny — 11¢ Kalshi $0 (weight 0%) - Will Beyoncé be on Jimmy Kimmel Live! before 2027?: Beyoncé — 8¢ Kalshi $0 (weight 0%) - Will Billie Eilish be on Jimmy Kimmel Live! before 2027?: Billie Eilish — 8¢ Kalshi $0 (weight 0%) - Will Charli D’Amelio be on Jimmy Kimmel Live! before 2027?: Charli D’Amelio — 6¢ Kalshi $0 (weight 0%) - Will Dwayne “The Rock” Johnson be on Jimmy Kimmel Live! before 2027?: Dwayne “The Rock” Johnson — 7¢ Kalshi $0 (weight 0%) - ... and 8 more --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged.
