Events and Outcomes

What is an Event?

An Event is a real-world question that will eventually have a clear answer, for example:

  • “Bitcoin to close above $100,000 on 31 Dec 2025?”

  • “Team A to win the championship?”

  • “Tokyo to experience an earthquake above X magnitude this year?”

Each Event has:

  • A start time (when trading opens)

  • An end time (when trading closes)

  • A resolution time (when the outcome is known and payouts are made)

Outcomes

Each Event offers two or more Outcomes, for example:

  • YES / NO

  • Team A / Team B / Draw

  • Multiple time bands (e.g. “In March”, “In April”, etc.)

Outcomes are designed to be:

  • Clear

  • Mutually exclusive (only one can be correct)

  • Collectively exhaustive (one of them must happen)

Users trade on which Outcome they think will be correct.

How pricing works: crowd-priced outcome pools

EveryX does not use a traditional order book with bids and asks.

  • Every Event has pools for each Outcome where user trades go

  • The probability shown on the screen is derived from how much money is in that outcome’s pool relative to the others

Very simply:

Probability of Outcome A ≈ (Money in Pool A) ÷ (Money in Pool A + Pool B + Pool C + …)

As more money flows into an Outcome:

  • Its probability goes up

  • The probabilities of other Outcomes go down

This means:

  • You are effectively trading against the entire crowd, not a privileged market maker with deep pockets

  • Events can function without a 1:1 buyer and seller for every trade at the exact moment of entry
