Will Elon Musk post 400-419 tweets from June 9 to June 16, 2026?

What this market is about

The question is whether @elonmusk will make exactly 400 to 419 countable X posts from June 9, 2026 at 12:00 PM ET through June 16, 2026 at 12:00 PM ET. The market counts main feed posts, quote posts, and reposts; replies generally do not count, except for replies that appear on the main feed as tracked by the specified counter. The market resolves using the “Post Counter” on xtracker.polymarket.com, with X itself as a backup source if the tracker does not update properly.

Why the market exists

There is real uncertainty because Musk’s posting volume is highly dependent on his schedule, public activity, and how much he uses X in that particular week. The chosen range, 400-419 posts, is narrow enough that being slightly above or below it changes the outcome completely, so the market is really pricing a precise count rather than a broad judgment about activity. Readers following this page should pay attention to whether his posting pace appears unusually heavy or light as the resolution window approaches.

What can move the price

Posts made by Elon Musk during the June 9-16 window are the main driver, especially if he appears to be posting steadily throughout the week or, conversely, goes quiet for long stretches. Because only certain post types count, quote posts and reposts can matter just as much as original main-feed posts, while replies usually will not unless the tracker includes them as main-feed replies. Any change in how the tracker records posts, or any dispute over whether a specific item counts, could also affect the market.
