Moderate risk exists. Resolution relies on a specific third-party tracker (xtracker) and involves nuanced rules (e.g., specific exceptions for main feed replies, and counting deleted tweets if captured within 5 mins). This can cause discrepancies between the tracker data and native user observations on X.

Highly exotic. Betting on the exact tweet volume of a public figure over a random 48-hour window is a pure novelty market tailored for crypto-native speculation, rarely seen in traditional or serious forecasting.

April 16, 2026 - April 17, 2026, the price of the '90-114' option rose from 18.5c to 32.5c, as the market observed an increase in his posting frequency, leading to an upward revision of the expected total. April 16, 2026 - April 17, 2026, the price of the '40-64' option plunged from 30.5c to 8.5c, because the actual number of tweets has likely approached or exceeded the lower bound of this range, making it unlikely to be the final result. April 16, 2026 - April 17, 2026, the price of the '65-89' option rose from 37.5c to 52.5c, because as time progressed and posts accumulated, this range became the most likely outcome fitting his current posting pace. April 13, 2026 - April 15, 2026, the price of the '140-164' option plunged from 11.5c to 2.85c, as the market quickly corrected the initial overpricing. April 13, 2026 - April 14, 2026, the price of the '40-64' option rose from 19.5c to 28c, due to market expectations of a potential slowdown in tweet frequency.

The main risk lies in the definition of FDV and data sources. FDV depends on Total Supply and Price; the definition of Total Supply at launch can be contentious (e.g., whether to include locked tokens). Additionally, the 'most liquid price source' can be highly volatile or subject to manipulation in the early stages. The condition that the market resolves to 'No' if the token doesn't launch by end of 2026 is also a significant time-based risk.

This is a niche market concerning the token launch of a specific crypto startup (USD.AI). Apart from those following DeFi and stablecoin sectors, the general public is likely unaware of it. It represents specific vertical speculation rather than a mainstream topic.

Apr 14, 2026 - Apr 17, 2026, the prices of the $250M, $300M, and $400M options all saw massive surges of over 20c (e.g., $400M skyrocketed from 14c to 38.5c). This was driven by a likely key bullish catalyst, such as a top-tier exchange listing announcement or tokenomics disclosure, which led the market to drastically upward-revise its FDV expectations. Apr 13, 2026 - Apr 16, 2026, the price of the $200M option surged from 57.5c to 79.5c, accompanied by significant rallies in the $250M and $300M options. This was driven by potential major liquidity or ecosystem partnership disclosures, leading to a sharp rise in market expectations for its valuation floor, triggering aggressive buying. Apr 13, 2026 - Apr 15, 2026, the price of the $200M option surged from 57.5c to 74c, accompanied by significant rallies in the $250M and $300M options. This was driven by potential major liquidity or ecosystem partnership disclosures, leading to a sharp rise in market expectations for its mid-tier valuation floor, triggering aggressive buying. Apr 8, 2026 - Apr 10, 2026, the price of the $300M option surged from 23.35c to 33.5c. As the token launch approaches or the project team signaled new liquidity partnerships, market capital became more optimistic about breaking through the mid-to-high valuation range ($300M), with obvious long capital intervention. Apr 6, 2026 - Apr 7, 2026, the price of the $250M option rebounded sharply from 35.5c to 48.5c, as the market rapidly recovered its expectations for the mid-to-high valuation tier after a brief pessimistic correction, likely driven by new positive rumors or a reassessment of launch liquidity. Apr 5, 2026 - Apr 6, 2026, the price of the $250M option plummeted from 49.5c to 35.5c, as the market rapidly cooled its expectations for the upper valuation bound after initial optimism, with capital correcting the overpriced tier. Apr 1, 2026 - Apr 4, 2026, the price of the $100M option surged from 79c to 96c, and the $150M option rose from 65c to 82.5c, as the market became extremely optimistic about the successful token launch and achieving base valuation, with significant capital rushing into high-certainty lower valuation tiers. Mar 30, 2026 - Apr 2, 2026, the price of the $200M option surged from 27.5c to 47.5c, the $150M option rebounded sharply from 60c to 78c, and the $100M option rose from 73c to 89c, as market sentiment strongly recovered after an oversell, with capital heavily scooping up lower-to-mid tier valuations based on stabilized launch expectations. Mar 30, 2026 - Apr 1, 2026, the price of the $200M option rebounded sharply from 27.5c to 41.5c, as bottom-fishing capital entered after the previous oversell, or positive rumors regarding the project's ecosystem partnerships and market-making arrangements drove a recovery in mid-tier valuation expectations. Mar 28, 2026 - Mar 30, 2026, the price of the $200M option plummeted from 52.5c to 27.5c, and the $150M option fell from 69c to 60c, as market confidence in its mid-tier valuation collapsed due to a shrinking expected launch window and lack of substantial positive news. Mar 25, 2026 - Mar 27, 2026, the price of the $100M option surged from 47.5c to 82c, as market capital corrected the extreme pricing inversion and reassessed the probability of success in the lower valuation bracket. Mar 25, 2026 - Mar 27, 2026, the price of the $200M option rose from 33c to 51c, reflecting a shift of funds towards defensive valuation ranges amidst fine-tuned launch expectations. Mar 18, 2026 - Mar 25, 2026, the price of the $150M option collapsed continuously from 85.5c to 69c, due to spreading market panic as investors aggressively priced in the risk of 'failure to launch by end of 2026'. Mar 19, 2026 - Mar 23, 2026, the price of the $300M option fell from 43.05c to 34.45c, continuing the trend of pricing in a break below the expected issue price, indicating extremely fragile buy-side support.

The title mentions 'Seoul', but the rules strictly use data from the Incheon International Airport Station (RKSI). Incheon is coastal and its temperatures often differ significantly from central Seoul, potentially misleading title-only bettors. Additionally, data is rounded to whole degrees Celsius.

April 16, 2026 - April 17, 2026, the price of 17°C surged from 25.5c to 46.5c, while 15°C plummeted from 16.5c to 2.4c, 16°C fell from 29c to 17.5c, and 19°C dropped from 17.5c to 7c. This is because weather forecasting models have become increasingly confident that the high will hit 17°C as the resolution date approaches, eliminating earlier uncertainties regarding lower or higher temperatures.
