Polymarket is the world's largest prediction market, where users trade on the real-world outcomes of events across Climate & Science and many other topics. Prices are quoted from 0 to 100 cents and reflect the implied probability that an event will occur. Because traders put real money behind their views, Polymarket odds represent a real-time, skin-in-the-game consensus, often referred to as the "wisdom of the crowd."

A Space prediction market lets users trade Yes or No shares on a specific question tied to Space-related events, such as "SpaceX IPO Closing Market Cap (Lower Strikes)". Each share pays out $1 if the outcome resolves in its favor, and $0 if it does not. The current share price, for example, 62% on "2.0T+", reflects the market's implied probability for that outcome at any given moment.

The Climate & Science category hosts 456 markets covering a wide range of subjects. Popular subcategories include Weather, Daily Temperature, and Space, each with its own dedicated page showing live odds, trading volume, and active markets. You can browse the full list of Climate & Science subcategories from the left-side navigation on the Climate & Science page.

Every Climate & Science market on Polymarket has outcomes priced between 0¢ and 100¢. That price is the implied probability of the outcome occurring. For example, if "2.0T+" is trading at 62% in "SpaceX IPO Closing Market Cap (Lower Strikes)", traders are collectively pricing in roughly that probability. Prices update continuously as new information, data releases, and events move trader sentiment.

Activity is constantly shifting, but you can sort the page by 24-hour volume to see where trading is concentrated. Currently, "Will SpaceX or OpenAI IPO first?" is among the most actively traded markets on the Space page, alongside other high-volume markets like "SpaceX IPO Closing Market Cap (Lower Strikes)" and "SpaceX IPO Closing Market Cap".

Each Climate & Science market has a clearly defined resolution source and criteria published on the market page. When the event concludes, for example, when a result is officially reported, a deadline passes, or an authoritative source confirms the outcome, the market resolves and winning shares pay out $1 each. Markets in categories such as Elections, Economy, and Geopolitics typically rely on official government, regulatory, or primary-source reporting for resolution.

Climate & Science markets respond in real time to news, announcements, data releases, and policy shifts. A single development, such as a new poll, economic indicator, court ruling, or geopolitical event, can materially change the implied probability of an outcome.

Prediction markets and traditional forecasts, such as polls, models, or analyst estimates, are complementary tools.
