Description
This market will resolve to "Yes" if @elonmusk posts the listed term between September 14, 2026, 12:00 AM ET and September 20, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." For the purposes of this market, all text posted by the listed account in quote and reply posts count toward a "Yes" resolution, but quoted posts and reposts will not count. Text posted in images, memes, or other non-animated, non-video media that are not strictly text will qualify towards a "Yes" resolution only if the listed term is spelled out clearly and in full. (e.g., words spelled out in a letter posted as a .jpg will qualify, however a word posted as part of an animated .gif will not.) Any plural or possessive forms of a listed term, as well as variance in capitalizations, will count toward the resolution of this market, regardless of context. Other forms of the listed term will NOT count. Extraneous symbols being inserted into a word (ex: r@d1cal, for "radical") will disqualify it from counting toward a "Yes" resolution. Sigils at the beginnings of words, such as hashtags, "@" symbols, or denotations of currency, will not disqualify a term from counting towards a "Yes" resolution. Misspellings or iterations of the listed term, including all grammatical or slang forms, or misspellings with extra, missing, or incorrect letters (ex: helloooooooo or heoll, for ‘hello’), will not count toward a “Yes” resolution, regardless of context or intent. Instances where the term is used in a compound word will count regardless of context (e.g. joyful is not a compound word for "joy," however "killjoy" is a compounding of the words "kill" and "joy"). The resolution source for this market will be Elon Musk's verified X account: @elonmusk Please note, only the @elonmusk verified X account counts for this market, regardless of the URL for this profile. If Elon Musk posts from another account, it has no bearing on the resolution of this market.

Frequently asked questions
On Polymarket, this market is priced using a continuous double auction. Traders buy and sell shares representing their belief in the likelihood of each outcome. As more shares are bought for a specific outcome, its price increases, reflecting a higher implied probability. Conversely, selling shares drives the price down. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each share directly corresponds to the probability of that outcome occurring, with the total value of all shares summing to 1. This dynamic pricing mechanism allows the market to quickly incorporate new information and adjust expectations.
This market resolves around Sep 20, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the outcome will be determined by a review of Elon Musk’s posts on X during the period of September 14th to September 20th. The resolution will reflect whether any of the specified outcomes – as defined by the market’s options – occurred during that timeframe. The market will be settled based on publicly available data and documented posts from Elon Musk’s official X account.
Several signals or events could significantly move this market before Sep 20, 2026. Any unexpected announcements from Elon Musk, particularly those related to controversial topics or policy changes, would likely cause substantial shifts in the odds. Major news events impacting Tesla or SpaceX could also influence trader sentiment. Additionally, significant engagement with existing posts – such as viral replies or media coverage – could trigger price movements. Finally, Elon Musk’s own statements about his posting intentions could directly impact this market.
