Up or down rounds

Polymarket runs back-to-back rounds on the big coins that ask one question: will the price be higher at the end than at the start? Backd shows them at Up or down, with your friends' calls on the same round.

The rounds

RoundHow oftenGood for
5 minutesOne after another, all dayA quick call on the next few minutes.
15 minutesOne after another, all dayA bit more room for the price to move.
4 hoursSix a dayA session, not a moment.
DailyNoon to noon, New York timeA call on the day. Slower, and the one that goes in combos most.

Every length runs for Bitcoin, Ethereum, Solana and XRP. Pick the coin and the round length at the top of the page.

How a round works

The price to beat is the price at the start of the round. Above it at the end is Up, at or below is Down. You see the chance of each, what your stake wins, the live price and a line of the round so far. Calls close 30 seconds before the round ends, and the page rolls into the next round by itself.

How it settles

Rounds settle on the official price Polymarket publishes for that round. The live price on the page is Polymarket's feed of Chainlink's 60-second average, the same one rounds settle on, for reference, so it can differ slightly. Winning shares can be claimed once the round resolves, usually within about 15 minutes.

Take it easy

Short rounds move quickly and it's easy to lose track of time and money. The first visit shows a note. Step away whenever it stops being fun, and prefer the longer rounds if the short ones start to feel like a reflex. Rounds can't be challenged and only one pick per round goes in a combo.

Polymarket may charge its own fee on these rounds, taken on Polymarket's side when the order fills. It goes to Polymarket, not Backd. See fees.
Backed calls are real positions. Your money sits in a wallet only you control; Backd never holds it.XTelegram
