A FEW QUESTIONS WORTH ASKING
Pick a perspective.
A DIFFERENT VIEW OF WHAT COMES NEXTThe future is a question.
The future is a question.
Give your view a position.
A prediction market turns a specific question into YES and NO shares. Their prices summarize how participants value the possible outcomes. Parallax lets you explore that mechanism with sandbox credits in a local development environment.
A view, made visible.
A 0.62-credit YES share is often read as a 62% implied probability. It reflects a price, not certainty.
One result. Defined rules.
Under a binary payout, a winning share returns 1 credit and a losing share returns 0. Fees affect the net result.
THE MECHANICS LABMove the price.

See the trade change.
A YES share pays 1 sandbox USD if the final outcome is YES, or 0 if it is NO. Its purchase price sits between those two values.
