9% — Will Martha Stewart be on the cover of 2027 Sports Illustrated Swimsuit Issue Kalshi 9% · 19 contracts · $0 volume · medium confidence Updated 2026-07-13 04:26:32 UTC Why this matters: This probability represents the estimated chance that Martha Stewart will be selected as the cover model for Sports Illustrated's 2027 Swimsuit Issue. The 26% probability reflects active betting interest on Kalshi, where Stewart competes against younger models like Ella Halikas (42¢), Haley Kalil (19¢), and others. The current level likely reflects Stewart's recent high-profile career resurgence, including her Netflix series and renewed cultural relevance, balanced against traditional industry conventions that historically favor younger models for the swimsuit issue. The probability will shift based on any official announcements from Sports Illustrated regarding their 2027 cover selection process or confirmed cover model. The main resolution point occurs when SI officially announces their 2027 Swimsuit Issue cover, expected sometime in late 2026 or early 2027 before the physical issue release. Key factors: - Martha Stewart is 84 years old as of 2026, making her significantly older than typical SI Swimsuit cover models, which historically skews toward models in their 20s-30s - Stewart's recent media prominence through Netflix collaborations and brand partnerships may increase her cultural visibility and appeal to SI's editorial team - SI has occasionally featured non-traditional cover models and personalities, creating precedent but remaining statistically rare in the publication's history - Competing models like Ella Halikas show higher betting probability (42¢), suggesting market participants view younger alternatives as more likely choices - No confirmed announcement from SI regarding their 2027 cover selection criteria or timeline has been made public as of May 2026 Contracts: - Will Brooks Nader be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Brooks Nader — 6¢ Kalshi $0 (weight 5%) - Will Camille Kostek be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Camille Kostek — 9¢ Kalshi $0 (weight 5%) - Will Olivia Dunne be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Olivia Dunne — 5¢ Kalshi $0 (weight 5%) - Will Jordan Chiles be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Jordan Chiles — 11¢ Kalshi $0 (weight 5%) - Will Ciara be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Ciara — 7¢ Kalshi $0 (weight 5%) - Will Yumi Nu be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Yumi Nu — 12¢ Kalshi $0 (weight 5%) - Will Haley Kalil be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Haley Kalil — 7¢ Kalshi $0 (weight 5%) - Will Nina Agdal be on the cover of 2027 Sports Illustrated Swimsuit Issue?: Nina Agdal — 5¢ Kalshi $0 (weight 5%) - ... and 11 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.
