Traders assign a 90.5% implied probability to “No” on another Elon Musk child by June 30 due to the complete lack of official announcements, credible reporting, or even late-stage pregnancy rumors since the February 2025 birth of his fourteenth child with Shivon Zilis. Musk’s pattern of understated post-birth disclosures, combined with biological timelines that would require conception nearly nine months ago, leaves no visible indicators. His public focus remains on xAI large language model releases, Tesla Full Self-Driving milestones, and SpaceX orbital launches, with no signals of personal developments that could shift the timeline. While a quiet surrogate birth or premature delivery remains possible in theory, the absence of supporting leaks or social-media hints keeps such scenarios priced as low-probability tail risks by resolution.
