This market will resolve according to the number of times Jon Rothstein (@JonRothstein) mentions "This is March" in a tweet posted on X between March 1, 2026, 12:00 AM ET and April 7, 2026, 2:00 AM ET. For the purposes of this market, only main feed posts, quote posts, and reposts will count. Only posts live at the listed time will count toward the final tally. Deleted posts or posts that were reposted and later un-reposted will NOT count. Text posted in images, memes, video, or any attachments will not qualify towards the final count. Any plural or possessive forms of the 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: Th1s, for "this") will disqualify it from counting toward the final count. Misspellings or iterations of the listed term, including all grammatical or slang forms, or misspellings with extra, missing, or incorrect letters (ex: marchhh or mar., for ‘March’), will not count towards the final count, regardless of context or intent. Instances where the term is used in a compound word will count regardless of context (e.g. marchmadness mentions are not a compound word for "march"). Instances where both the quote and the quoted post contain the relevant phrase will qualify as one mention. (e.g., if John quotes a post which contains "This is March" with his own text containing "This is March", it will qualify as one mention.) If the relevant data is unavailable by April 20, 2026, 11:59 PM ET, this market will resolve to the lowest bracket. The resolution source for this market will be Jon Rothstein’s verified X account: @JonRothstein. Please note, only the @JonRothstein verified X account counts for this market, regardless of the URL for this profile. If Jon Rothstein posts from another account, it has no bearing on the resolution of this market.
