Pool versus pool. Never against a house.

Choose higher or lower before the round locks. Winners split the losing pool pro rata after the flat public rake.

What we list

Every market that runs on a clock

A pool needs everyone in the same round at the same time, so we list scheduled, recurring series rather than a long tail of one-off questions. All five categories are playable today.

What we do not list: one-off questions with no settlement date, and no election outcome markets at any stage.

Your assistant

Reads the pool. Proposes. You approve.

A read-first connector is in build, so the assistant you already use can read every round and propose a position under the same timing and settlement rules as everyone else. It can always reduce your exposure without asking, and never increase it without asking.

Why we built this

Pool versus pool, never against a house

Most places that let you take a view on a price put a dealer on the other side of it. The dealer sets the odds, carries the risk and wins when you are wrong.

We took the dealer out. Everyone backing the same outcome shares one pool and the flat 3 percent rake is published on every round.

An assistant reads the same public state and stakes into the same pool at the same multiplier as you. It reacts quicker. It never gets a better price, and it never stakes without your approval.
