What Is DeepBook Predict and How Sui's One-Minute Bitcoin Markets Price Every Trade

DeepBook Predict is the Bitcoin prediction market that opened to traders inside Sui's DeepBook App on 24 September 2026, and it lets you pick any price or trade a range with expiries from one minute to two weeks. One shared pool of liquidity providers takes the other side of every position, and an oracle prices each range on demand.

The launch put Predict and DeepBook's spot order book into one app after more than 150,000 traders joined the waitlist, according to the Sui Foundation's launch post. SUI's perpetual on Phemex closed launch day 5.66 percent higher at 1.0137, then gained 17.88 percent on the 25 September bar to close at 1.195. That's timing, and it doesn't prove the app moved the coin.

How DeepBook Predict Works

Every position on DeepBook Predict is a range contract. The Predict developer documentation says each one "pays a fixed amount when the settlement price lands inside a chosen strike range, and nothing otherwise." You know your maximum loss and your maximum payout before you click.

A directional view is the same contract with one end left open. Buy the up side and you're paid when settlement lands above your strike, while the down side pays when it lands at or below it. The quantity you choose is the maximum payout in USDC, sized in whole lots of $0.01. The premium you pay is that quantity multiplied by the probability the oracle quotes at entry. And every trade carries a floor, because the protocol rejects any premium under 1 USDC.

That floor has a practical edge for small accounts. On a 10 USDC payout, the quoted probability has to reach 10 percent for the premium to clear 1 USDC. The tightest ranges only open up once you size the payout larger.

The launch post's own illustration is a $15 Bitcoin range from $78,705 to $78,720 that the trader picks for themselves. Each market lives as its own shared object on Sui, an alternative layer-1 focused on scalability, so trades in one market don't slow another.

The Sui Foundation credits that parallel design, plus fast settlement, for making one-minute markets viable entirely onchain. If you're comparing Sui with other fast chains on those terms, our Sui vs NEAR comparison puts the two side by side.

Who Takes the Other Side in the DeepBook Protocol

Predict has no trader on the other side of your position. Liquidity providers supply USDC to one shared pool and receive PLP shares in return. That pool takes the other side of every trade, so when you win the providers pay.

For the providers the trade runs the other way. PLP holders keep the premiums paid on ranges that miss and pay the full quantity on ranges that hit, so their return depends on the oracle pricing each range fairly across a steady run of short markets.

Money doesn't move in and out of the pool instantly either. Providers queue deposits and withdrawal requests with an optional floor, and a periodic flush fills them all at one frozen pool value.

DeepBook's older product is a central limit order book on Sui, where bids and asks rest onchain and match by price and time. More than 15 apps route through that book, which the Sui Foundation says has powered trading on Sui for three years and puts at over $20 billion in volume. Predict swaps that matching for a pool quote. The launch post's FAQ compares it to asking a derivatives desk for a custom quote. That's the desk side of the trade-off in our guide to OTC and order book trading for high-net-worth traders. A pool that answers every request needs depth behind it, and for a trader that depth is the number to track.

How a Sui Prediction Market Prices Every Trade

Predict doesn't publish a menu of strikes. According to the launch post, an oracle prices the full probability curve and derives a price for any level. The market for your exact range comes into being when you ask for it.

Method: the Predict documentation names the feeds as Pyth Lazer spot prices plus Block Scholes forward and stochastic volatility inspired (SVI) data. Block Scholes built a high-frequency volatility oracle for this product, the launch post says.

Each market settles once, at one timestamp. The settlement price is the exact Pyth price at expiry. If that price isn't available 30 seconds after expiry, the market settles on the exact Block Scholes minute-boundary spot. Trading closes 2 seconds before expiry on both deployments, and any trade sent inside that window aborts.

That cutoff shapes the one-minute market more than the headline suggests. The documentation's own sample code skips any market with under 30 seconds left. A quote taken in the closing seconds of a 1-minute contract goes stale before the trade lands, and the cost cap then rejects it. On the shortest cadence, your working window after a fresh quote is well under a minute.

What Markets Does DeepBook Predict Run and Who Can Trade Them?

Both deployments run BTC markets on the 1-minute and 5-minute cadences, with two expiries of each live at once, according to the documentation. The protocol defines six cadence sizes from 1 minute to 1 month, and the launch post advertises timeframes up to two weeks. The documentation, though, lists only the 1-minute and 5-minute cadences as enabled on the deployments it describes.

The documentation also carries a caution worth reading before you fund an account. It describes two deployments that went live on 12 September 2026. At the last recorded chain read, it says, the four markets each network created at deployment had expired unsettled. The same note says the mainnet pool holds "only the bootstrap minimum." The note gives no date for that read, and the app launched on 24 September, so check the app's live market list before you assume a range will quote.

Access has limits too. The launch post names 11 jurisdictions where DeepBook App is unavailable, among them Russia and Singapore, and says United States users get Spot trading without Predict.

DEEP, the DeepBook crypto token, trades as a DEEP/USDC pair on DeepBook's spot market. On Phemex its perpetual is delisted and its spot pair is delisted too, so the Sui-linked contracts you can trade on Phemex are SUI's own, the SUI/USDT and SUI/USDC perpetuals among them.

How SUI Traded Around the DeepBook Sui Launch

SUI's perpetual on Phemex closed at 1.0137 on 24 September, the launch day, up 5.66 percent from 0.9594. The 25 September bar traded as high as 1.2161 and closed at 1.195 for a 17.88 percent gain, on turnover of $24.15 million against $18.73 million on launch day. The close sat 1.74 percent under the bar's high, so buyers held nearly all of the intraday move into the daily close.

Among the 132 Listed Phemex perps with a one-day move on that bar, SUI's USDC and USDT contracts ranked second and third behind ENA's 19.63 percent. Bitcoin closed the same bar 0.37 percent lower while 98 of those 132 perps closed higher, so SUI rose on a green board with Bitcoin flat.

The chart also shows SUI moving before the app existed. The 21 September bar took SUI from 0.8971 to 1.0423 for a 16.19 percent gain three days ahead of the launch. SUI then closed lower on 22 and 23 September. So the launch lines up with the biggest bar of the week, and a move of similar size landed three days earlier that the app can't have caused.

The SUI/USDT perpetual on Phemex offers up to 50x leverage and settles funding every 8 hours. Our guide on how to read crypto futures funding rates walks through what those payments tell you after a bar like 25 September.

Frequently Asked Questions

Who runs DeepBook App?

The DeepBook Trading Foundation launched it. Its chief executive Glenn Kennedy said in the launch post that Spot and Predict are "the first two products on that roadmap." The Predict contracts on mainnet come from Mysten Labs' DeepBookV3 source code on GitHub.

Is DeepBook Predict audited?

The launch post says the protocol is audited and runs an active bug bounty program. Its "audited" link opens a DeepBook V3 audit file in the Sui Foundation's security-audits repository, and the file name doesn't mention Predict.

Do you need SUI to use Predict?

You need SUI for gas, and the documentation recommends keeping a working reserve of at least one SUI. On mainnet the quote asset is Circle's native USDC, and there is no faucet.

Bottom Line

DeepBook Predict's real product is the oracle curve, because it turns any Bitcoin range a trader types into a price on demand. That design moves the risk onto one USDC pool, and the pool's depth will decide how large the market gets long before any one-minute chart does. SUI's 17.88 percent bar on 25 September came the day after the launch, and the chart can't say the app caused it. The number that tells you if Predict works as a product is the size of that pool.
