There is a significant copy-paste error in the rules: while the title and most of the text refer to the Scottish Parliamentary Election, the resolution clause incorrectly states it will be based on seats won in the 'Welsh Parliament' and mentions the 'Welsh government'. Although the link points to the correct Electoral Commission of Scotland and 'Scotland' is the dominant context, this textual conflict creates a material ambiguity risk.

The complexity of the rules lies in its reliance on a specific tracker (Polymarket's xtracker) and specific types of tweets. Replies are excluded unless they appear on the main feed. Furthermore, deleted tweets count if they survive long enough (~5 mins) to be captured. These technical details could create discrepancies compared to manual observation on X.

Predicting the exact number of tweets a person posts in a week is a highly niche and entertainment-driven market. Typically, the general public or traditional financial markets do not care about such highly specific and random behavioral data.

April 13, 2026 - April 14, 2026, the price of the 300-319 option surged from 30.5c to 61.85c, as post volumes locked into this range close to settlement, making it the most likely final outcome. April 13, 2026 - April 14, 2026, the price of the 320-339 option fell from 41.85c to 26.8c, as the likelihood of reaching this higher bracket within the remaining time decreased, shifting probabilities lower. April 13, 2026 - April 14, 2026, the price of the 320-339 option rose from 27.95c to 41.85c, as continued posting close to settlement made this bracket the most likely final landing spot. April 13, 2026 - April 13, 2026, the price of the 300-319 option plummeted from 57.9c to 30.5c, as slight shifts in posting speed increased the likelihood of higher brackets, splitting the probabilities. April 13, 2026 - April 13, 2026, the price of the 340-359 option fell from 26.95c to 8.95c, as the remaining time to achieve this high count dwindled, cooling market expectations. April 13, 2026 - April 13, 2026, the price of the 300-319 option surged from 21.5c to 52.9c, as with less than a day remaining, the current posting pace indicates this bracket is the most likely final landing spot. April 12, 2026 - April 13, 2026, the price of the 340-359 option surged from 0.25c to 26.95c before falling back to 17.95c, driven by a massive spike in posting frequency pricing in higher totals, though expectations later converged. April 12, 2026 - April 13, 2026, the price of the 360-379 option surged from 0.15c to 15.55c before falling to 7.45c, as surging post volumes prompted bets on an extremely high final count, followed by a rational pullback. April 12, 2026 - April 13, 2026, the price of the 320-339 option surged from 0.65c to 39.5c before settling at 33.05c, as extremely high weekend posting volume made it the most likely landing bracket temporarily before recent data cooled it off. April 12, 2026 - April 13, 2026, the price of the 280-299 option plummeted from 33.0c to 0.55c (later bouncing to 4.2c), because the overly fast posting pace led actual data to quickly blow past this bracket. April 12, 2026 - April 13, 2026, the price of the 260-279 option plummeted from 38.5c to 0.05c, for the same reason, as actual posting volume completely surpassed this defensive bracket. April 11, 2026 - April 12, 2026, the price of the 220-239 option crashed from 29.5c to 2.5c, because recent posting volumes basically guarantee the final count will far exceed this defensive bracket. April 9, 2026 - April 12, 2026, the price of the 240-259 option surged from 26.5c to 43.5c, because as the tracking period nears its end, Elon's actual posting frequency remained stable, making it highly probable for the final count to fall into this bracket, causing market expectations to heavily concentrate. April 9, 2026 - April 11, 2026, the price of the 220-239 option rose from 12.5c to 26.5c (later settling around 29.5c), due to a temporary slowdown in posting volume, triggering defensive pricing for a lower final count. April 7, 2026 - April 11, 2026, the price of the 260-279 option increased from 17.5c to 28.5c (later settling at 16.5c), because the initial posting speed was fast, aligning highly with this bracket's projection for a time, before slowing down and losing momentum.

The title simply says 'tweets', but the rules explicitly exclude standard 'replies', which make up a massive portion of Musk's activity, creating a counter-intuitive pitfall. Additionally, resolution relies heavily on a specific custom tracker (xtracker), introducing technical risks of missed counts or downtime, especially for deleted posts.

This is a highly typical long-tail novelty market. Outside of prediction market degens, nobody naturally contemplates or calculates the exact number of times a specific celebrity posts on social media during a random week. It is purely for entertainment.

April 11, 2026 - April 14, 2026, the price of the '320-339' option surged from 3.1c to 26.2c, as the actual high posting speed made it the highest probability target via linear extrapolation. April 11, 2026 - April 14, 2026, the price of the '300-319' option surged from 5.5c to 23.5c, as the posting speed stabilized at a high level, turning it into a core favorite. April 11, 2026 - April 14, 2026, the price of the '340-359' option surged from 1.6c to 15.9c, as significantly increased posting velocity shifted market expectations upward. April 12, 2026 - April 14, 2026, the price of the '280-299' option plummeted from 21.5c to 7.6c, because accelerating volumes meant the total will likely easily surpass this bracket. April 11, 2026 - April 14, 2026, the price of the '260-279' option plummeted from 21.5c to 2.0c, as the high-frequency weekend posting confirmed this bracket would be massively breached. April 11, 2026 - April 14, 2026, the price of the '380-399' option surged from 0.7c to 12.9c before settling at 7.5c, as some bettors speculated on an extreme posting spree.

Predicting the debut week sales of a specific artist is a relatively standard pop culture/entertainment market. It has a dedicated niche audience of chart watchers and music industry trackers, but isn't universally followed like elections or macroeconomics, making it moderately niche.

April 12, 2026 - April 13, 2026, the price of the '140k+' option surged from 72.5c to 90c, while the '120k-140k' option plummeted from 18c to 6.5c. This occurred because early tracking data for the album's first weekend (such as Hits Daily Double projections) further confirmed expectations that sales would significantly exceed 140,000 units, leading the market to price in this outcome almost entirely. April 10, 2026 - April 12, 2026, the price of the '140k+' option surged from 53.5c to 76c, driven by early data performance following the album's official release exceeding expectations, leading to heavy betting that debut week sales will surpass 140k. April 10, 2026 - April 12, 2026, the '120k-140k' option dropped from 35.5c to 15c, and the '100k-120k' option fell from 28c to 7c, as market confidence shifted to the highest sales bracket, ruling out lower ranges. April 8, 2026 - April 11, 2026, the price of the '140k+' option surged from 45c to 67c, while the '120k-140k' option dropped from 44.5c to 22.5c. This was driven by recent streaming data and early projections elevating sales expectations as the album release approached, causing capital to heavily concentrate in the highest bracket. April 8, 2026 - April 10, 2026, the price of the '80k-100k' option plummeted from 35.5c to 18c, and '100k-120k' fell from 41c to 31c. The reason is a significant upward shift in debut week sales expectations, causing capital to rotate into higher brackets (>120k), alongside a gradual correction of market overpricing.
