A round is 60 seconds on any of six stocks, around the clock. The first bet opens it. Every bet goes into one pool. When the clock hits zero, the on-chain price decides, and the winners split the pool. No house takes the other side. $ROUNDS holders are paid in SPY.
From the team behind Hxro and OddsFi.
Six markets. One round each. Around the clock.
Uniswap never closes, so rounds run around the clock. On weekends the price moves less and more rounds refund on an equal average.
Markets are add-only. A new market is disclosed here and on X before its first round opens.
Pick UP or DOWN on any of six stocks. 1 to 200 USDG.
The round closes 60 seconds after it opens. The on-chain price decides.
Winners split the losing side. One click.
Nobody bets against you. Everyone bets against everyone.
The Uniswap price at the open and at the close. No one else.
Same price, or nobody on the other side: every bet comes back.
3% of the losing side. Fixed in the contract.
The price decides.Nobody else.
Everything this team built since 2021 priced crypto, because crypto was the only thing that never closed. On July 1, 2026 Robinhood Chain went live with tokenized stocks trading as plain ERC-20s 24/7, with Uniswap pools from block one. The Uniswap pool for a stock has a price at every block, and that is what ROUNDS settles on. "Will NVDA be higher in 60 seconds" at 3 a.m. on a Sunday is a market that can exist here and nowhere else.
In Q2 2026 Robinhood processed 13.6 billion event contracts. Event-contract revenue reached $156 million, more than it earned from equities or from crypto. Those contracts stop at the hour-and-day horizon a regulated order book can support. Nobody offers the one-minute layer on that stack.
100-millisecond blocks: a 60-second round is roughly 600 blocks. Open, bet, lock, close, settle, collect, with margin. What was missing elsewhere was a deep on-chain price for a stock and a native settlement asset. Here both exist at launch: Uniswap pools for the six launch stocks in USDG.
The launch primitive here lets a token trade, pay fees and graduate quoted in SPY, and route its creator fees to holders in SPY, automatically. This team has said "revenue index" for years. Here it is literal: $ROUNDS holders are paid in SPY, and they sign nothing.
