Definición sencilla
Un mercado de predicción trata sobre un evento futuro. Las personas negocian contratos vinculados a una pregunta clara, por ejemplo: «¿Ocurrirá esto antes de una fecha determinada?»
El precio muestra cuánto están dispuestos a pagar los participantes ahora. Nunca garantiza el resultado futuro.
Cómo funciona un mercado
Una plataforma publica la pregunta, la fecha y las reglas de resolución. Después, los participantes colocan órdenes de compra y venta para los resultados disponibles.
Cuando coinciden dos órdenes compatibles, se produce una operación. El precio puede cambiar con nueva información o con cambios en la liquidez.
Cómo leer un precio
Un contrato Sí cerca de 0,60 dólares suele leerse como una probabilidad implícita de alrededor del 60 %. Es una forma útil de resumir el mercado, no una predicción segura.
Antes de sacar conclusiones, lea la pregunta completa y revise el libro de órdenes y la cantidad disponible a ese precio.
Resolución y prudencia
Las reglas escritas determinan qué resultado gana. Una noticia no siempre resuelve un mercado de inmediato.
Lea reglas, comisiones y restricciones. Use solo servicios a los que tenga derecho a acceder y no arriesgue dinero que no pueda perder.
