Argue on X.
Settle on Yoko.

One side backs YES, the other backs NO, and Subtensor data decides who was right.

How a bout works.

Follow one bout from the first trade to the payout.

  1. Pick a side.

    A bout is one yes-or-no question about a subnet, pinned to a Subtensor block. Back YES or NO in TAO. The market maker always has a price, and every trade moves it.

    Each winning share pays 1 TAO.

  2. Bets close.

    Bets close at least an hour before the target block, and nobody can buy or sell after that. The result is measured over the day up to that block: one reading an hour, 24 in all, from public Subtensor data.

  3. The call.

    Yoko computes the result from those readings and posts it on-⁠chain with the hash of its evidence. The bout settles in the same transaction, and winners collect from the next block.

    It's final once posted, and anyone can recompute it.

The day bout #1 was called.

  1. Bout #1's measured day.

    7,200 blocks, about 24 hours, from block 9,132,463 to block 9,139,663.

  2. 24 readings of lium.io's pool.

    One every 300 blocks. Each column shows how far the pool stood above the 150,000 TAO needed.

  3. The window closed.

    Block 9,139,663 ended the day, and Yoko called bout #1 from its 24 readings.

Upcoming bouts.

Yoko calls each bout at a fixed Subtensor block, from public data. Trading opens with the app.

Before your first bout.

Ask us anything on X, @Yokomarkets (opens in a new tab).

What is a bout?

A yes-or-no question about a Bittensor subnet, pinned to a Subtensor block. It can ask about the subnet's rank or share by TAO injected, or the size of its pool. You buy YES or NO shares in TAO. When the result is in, each winning share pays 1 TAO.

Who calls the result?

Today a single reporter key posts each call. The result comes from public Subtensor data over the last hour before the target block (over the day, for the first bouts). It goes on-chain with the hash of its evidence, and it's final once posted. If the reporter stays silent, a guardian multisig can step in. Anyone can recompute a call from its evidence.

What do I need to trade?

A wallet on Robinhood Chain, some bridged TAO, and a little ETH for network fees. Prices are in TAO per share, between 0 and 1, and each winning share pays 1 TAO. Every trade pays a 2% fee, and the app shows the exact cost, fee included, before you confirm.

What if the target block comes early?

The bout is void if the target block lands too soon after bets close. Each bout's own rule sets the minimum gap: one hour on today's bouts, 6 hours on Bout #1. A void refunds every share, YES or NO, the same amount from the bout's pot.

Can the house run out of money?

One shared vault of TAO, funded by seeders, backs every house bout. Before a house bout's first trade, the vault locks away the most it could ever lose on it. Seeders can't withdraw below those reserves plus a 10% safety floor. Assets, reserves and coverage are public contract reads, and the app shows them.

Can anyone host a bout?

Yes. Pick a subnet, a question and how long bets stay open, then put up the money behind it in TAO. Only you fund your bout. Everyone else bets YES or NO. The most you can lose is what you put in, and whatever the bout doesn't use comes back to you.

Can I add money to someone else's bout?

No. Only the host backs a hosted bout. Everyone else bets YES or NO, and the bout's 2% fee goes to Yoko. To back bouts without hosting one, deposit TAO in the house. It backs every house bout together, and its seeders share in 70% of the trading fees on house bouts. The house takes the other side of each of those bouts, so seeders can lose money: together, up to what the house has reserved on the bouts in play.

Can my team trade a bout on our own subnet?

Yes. Anyone can trade any bout, its host and the subnet's own team included. Your team can host a bout on your subnet, then back YES or NO like any other trader.

What are the risks?

You can lose everything you put into a bout, and each call is final when posted. Seeders of the house can lose money too: together, up to what the house has reserved on its bouts in play. The contracts have been reviewed internally but not yet audited by an external firm. They can contain bugs that no review has found.
