This market measures whether Elon Musk will post 580 or more tweets during a seven-day window from April 14 to April 21, 2026. The threshold of 580 tweets breaks down to an average of approximately 83 posts per day. Musk's Twitter activity has historically varied significantly based on market conditions, major corporate announcements, and personal attention cycles. During high-engagement periods, he has posted in the 60-100+ range daily; during quieter phases, activity drops substantially lower. The metric is directly verifiable through Twitter's public API and historical post archives, making it a precisely resolvable market. The current odds sit at 0%, suggesting market participants assess the probability of this level of activity as negligible for this specific week. This reflects expectations that either Musk will reduce his posting frequency compared to previous high-activity periods, or that external events will limit his attention to Twitter. The market's significant liquidity ($27,548) and trading volume ($60,681 in 24 hours) indicate sustained interest in predicting his social behavior. Resolution will occur automatically once the week concludes and post counts can be verified against Twitter's public record.
