The market severely overestimates Ciro Gomes' chances of winning (63.5%). Mainstream political analysis suggests that given the strong dominance of the PT in Ceará (incumbent Elmano de Freitas and former governor Camilo Santana), Ciro Gomes is currently politically isolated, making a gubernatorial victory highly unlikely. This divergence is likely due to extremely poor market liquidity or irrational speculation by a few traders.

The primary risk lies in reporting lags and exclusivity. The rules explicitly state that only the CDC official counter is used for resolution. This means even if local state agencies or news outlets report widespread cases, they will not count unless updated on the CDC system by the deadline. Traders must account for the discrepancy between actual cases and officially published CDC numbers.

Forecasting measles cases is irrelevant in traditional financial markets, but in post-COVID prediction markets, public health and epidemiology have become a stable, albeit niche, category. It is not entirely absurd, but remains outside mainstream public discourse.

There is a significant rule trap. Retail participants often rely on financial websites for market cap, which frequently only calculate based on the publicly traded share class. However, the rules explicitly require including all unlisted share classes and applying conversion ratios, potentially resulting in a settlement market cap much higher than standard data sources show.

May 12, 2026 - May 13, 2026: The price of '$2.5B–$3.0B' surged from 32.5c to 49.5c, while '$3.0B–$3.5B' plunged from 20.5c to 6c, and '$2.0B–$2.5B' rose from 27c to 37c. This occurred as final subscription clarity emerged on the eve of the IPO, cooling expectations for extreme valuations (a massive first-day pop) and causing capital to rapidly consolidate into the reasonable $2.0B-$3.0B ranges. May 11, 2026 - May 12, 2026: The price of '$3.0B–$3.5B' surged from 10.5c to 24c, likely due to market expectations of a strong IPO debut and a significant first-day pop. May 11, 2026 - May 12, 2026: The price of '$2.0B–$2.5B' plunged from 32c to 10.5c before rebounding to 23.5c, reflecting market divergence on pricing and opening performance expectations, causing capital to quickly shift between adjacent brackets.

May 11, 2026 - May 12, 2026: The YES price for the 52-53°F option surged from 12.5c to 32c, while the 48-49°F option plummeted from 17c to 4.3c. This was caused by updated meteorological models as the date approached, which ruled out lower temperatures and consolidated the forecast into the 52-55°F range.

The title asks for the lowest temperature in 'Seoul', but the resolution rules strictly specify the 'Incheon Intl Airport Station'. Incheon airport is located on a coastal island and its temperature often differs significantly from central Seoul. This geographical discrepancy is a notable rule trap.

Asking for the exact lowest daily temperature of a specific city is a relatively niche topic. Aside from weather enthusiasts or locals, few people actively predict and trade this, although weather markets do have a standard presence in prediction markets.

May 11, 2026 - May 12, 2026: The price of the 11°C option dropped from 21.5c to 6c, the 14°C option dropped from 24.05c to 8.45c, and the 12°C option rose from 19c to 32c. This was due to weather forecast models converging as the date approached, confirming the lowest temperature would likely land in the 12-13°C range, thereby decreasing the probabilities of the edge ranges and increasing the core ranges.
