“Digital Assets” means a digital representation of value or rights which may be transferred and stored electronically, using distributed ledger technology or similar technology, including, but not limited to, cryptocurrencies, stablecoins, non-fungible tokens and any other digital asset.

"Dispute Period" means the period of three (3) to five (5) minutes immediately following the initial determination of a Market Outcome, during which the Platform may review and, if necessary, correct the settlement result before it becomes final.

“Event Contract” means a contract listed on the Platform with a binary payout based on the occurrence or non-occurrence of a specified real-world event (typically YES or NO).

"Entry Price" means, in respect of a Price Up Down Contract (as defined below), the reference price of the Digital Asset at the commencement of the relevant observation window, as determined by the Underlying of an Event Contract.

“Expiration” means the time on the Expiration Date at which an Event Contract expires and the Expiration Value of that Event Contract is determined.

“Expiration Date” means the date established by the Contract Specifications on which the Expiration Value of each Event Contract is determined.

“Expiration Value” means the rate, level, amount, measure, or other value of the Underlying at Expiration, calculated as the arithmetic mean of the OKX Spot Index Price (as defined below) second-level K-line open prices sampled during the Settlement Observation Window (as defined below), expressed to the price precision specified in the Contract Specifications.

“Market Outcome” means the result of an Event Contract. Where the Expiration Value falls within the parameters defined by the Payout Criterion, the Market Outcome shall be designated as "YES" (indicating that the specified event has occurred or the relevant threshold has been met). Where the Expiration Value does not satisfy the Payout Criterion, the Market Outcome shall be designated as "NO". The Contract Specifications may prescribe alternative or additional Market Outcome designations for specific Event Contracts.

"OKX Spot Index Price" means the real-time composite spot price index published by the Platform for a given Digital Asset, calculated by reference to prices across multiple leading spot exchanges in accordance with OKX's published index methodology.

“Outcome Review” means the process by which OKX, at its sole discretion, may review and determine the final Market Outcome where circumstances arise that may have a material impact on the reliability or transparency of the Underlying, as further described in Clause 8.

“Payout Criterion” means the Expiration Value or set of Expiration Values that will cause an Event Contract to pay a Settlement Value to the holder of a long position (or short position, as applicable) in such Event Contract. The positionholder that receives a Settlement Value is considered to be “in-the-money” while the positionholder that does not receive a Settlement Value is considered to be “out-of-the-money.”

“Position” means a User’s holding in one or more Event Contracts, which may be either a long position (a “buy” or “YES” position) or a short position (a “sell” or “NO” position).

"Price Above Contract" has the meaning given in Clause 4.2 of this Agreement.

“Settlement” means payment to Users who have the right to receive the Settlement Value pursuant to an Event Contract, held until Expiration.

“Underlying” means the index, rate, risk, measure, instrument, differential, indicator, value, contingency, occurrence, or extent of an occurrence that forms the basis of an Event Contract and determines whether such Event Contract is settled in-the-money.

4. Using the Services

4.1 Price Up Down Contracts. A Price Up Down Contract is a binary-outcome contract in which the Payout Criterion is whether the price of the Underlying at the Expiration is directionally higher ("Up") or lower ("Down") than the Entry Price, as specified in the Contract Specification.

4.2 Price Above Contracts. A Price Above Contract is a binary-outcome contract in which the Payout Criterion is whether the price of the Underlying at the Expiration on the Expiration Date is equal to or above the Strike Price specified in the Contract Specifications.

5. Account Funding and Collateral Requirements

5.1 Full Collateralisation. All Events Contract Positions must be fully funded prior to opening. OKX will not permit a User to open a Position without sufficient funds in the User's designated Events Contract balance to cover the full cost of the Position.

5.2 Funding Your Account. Prior to trading, Users must transfer eligible assets to their designated Events Contract balance on the Platform. The Platform will specify permitted funding currencies and transfer methods from time to time.

5.3 Collateral Hold. Upon the User's submission of an order, the Platform will place a hold on the funds required to collateralise that order. Funds subject to a hold may not be withdrawn or used for other purposes until the relevant order is cancelled or the Position is closed or settled.

5.4 No Margin or Leverage. Events Contracts do not employ margin or leverage. No margin calls will be issued. A User's maximum loss is limited to the funds committed at the time of opening the Position.

5.5 Funds in Transit. The Platform is not liable for delays in crediting or debiting your Events Contract balance resulting from third-party payment systems, network congestion, or technical errors outside the Platform's reasonable control.

6. Order Mechanics and Trading

6.1 Order Types. Events Contracts may be traded by submitting orders through OKX's order book interface. Orders may be placed as:

a. Buy / YES Orders to acquire a long Position, reflecting the view that the Market Outcome will be YES; or

b. Sell / NO Orders to acquire a short Position, reflecting the view that the Market Outcome will be NO.

6.2 Minimum Trading Unit. The minimum unit of trading for an Events Contract is as specified in the relevant Contract Specifications.

6.3 Minimum Price Increment. The minimum price increment for each Events Contract is as specified in the relevant Contract Specifications. Unless otherwise specified, the minimum increment is 0.01 per Contract (or its equivalent in the Platform's designated pricing unit). Order prices must be within the range of 0.01 to 0.99 (inclusive) per Event Contract unit. Orders at prices outside this range will be rejected.

6.4 Order Matching. Orders are matched on the Platform's central order book on a price-time priority basis. A match between a Buy / YES Order and a Sell / NO Order results in a binding trade between the parties at the matched price.

6.5 Opening and Closing Positions. Users may open new Positions or reduce or close existing Positions at any time during the trading hours specified for a given Event Contract, subject to market availability, applicable Position Limits, and the terms of this Agreement.

6.6 Order Cancellation by User. Users may cancel any unmatched order at any time prior to execution.

6.7 Trading Hours. OKX shall specify trading hours for each Events Contract in the relevant Contract Specifications. The Platform may modify trading hours with reasonable notice or immediately in the event of a market disruption.

7. Settlement

7.1 Settlement Trigger. Upon the Expiration, OKX will determine the Market Outcome for the relevant Event Contract by reference to the Expiration Value obtained from the Underlying of the Event Contract.

7.2 In the event that the Market Outcome is YES, (i) positionholders of Buy / YES Positions will receive the Settlement Value per unit of Event Contract held; and (ii) positionholders of Sell / NO Positions will receive zero in respect of their settled Event Contract units.

7.3 In the event that the Market Outcome is NO, (i) positionholders of Sell / NO Positions will receive the Settlement Value per unit of Event Contract held; and (ii) holders of Buy / YES Positions will receive zero in respect of their settled Event Contract units.

7.4 Price Up Down Settlement. For Price Up Down Contracts, the Expiration Value is compared to the Entry Price as follows to determine whether the Payout Criterion is met:

a. for an "Up" prediction - YES if Expiration Value is higher or equal to Entry Price; NO if Expiration Value is lower than Entry Price;

b. for a "Down" prediction - YES if Expiration Value is lower than Entry Price; NO if Expiration Value is higher or equal to the Entry Price.

OKX shall settle Price Up Down Contracts periodically at each Expiration (standardised intervals of 15 minutes or 1 hour as may be applicable). There shall be four (4) rolling expiries at 15-minute intervals (covering one (1) hour of rolling exposure at any given time). For the avoidance of doubt, Settlement does not occur prior to Expiration.

7.5 Price Above Settlement. For Price Above Contracts, settlement occurs solely on the Expiration Date at the Expiration. The Expiration for daily Price Above Contracts is 16:00 HKT (Hong Kong Time):-

a. YES if Expiration Value is higher or equal to the Strike Price;

b. NO if Expiration Value is lower than the Strike Price.

OKX will not settle a Price Above Contract, and will not make any payment hereunder, prior to the Expiration Date, irrespective of the price of the Underlying at any intervening time.

7.6 USDT Settlement. All Events Contracts are settled in USDT. No underlying Digital Asset is delivered, transferred, or otherwise conveyed to any User in connection with any Event Contract. Settlement amounts will be credited to the User's account on OKX following Settlement of the Market Outcome.

7.7 Two-Stage Settlement. Settlement of Events Contracts shall proceed in two stages as follows:-

a. Dispute Stage. Immediately following the initial determination of the Market Outcome, the result enters the Dispute Period, which is approximately three (3) to five (5) minutes. During the Dispute Period, (i) the Market Outcome and profit/loss are visible to the User and recorded in the User's account; (ii) OKX may initiate a Market Outcome Review; and (iii) any Settlement Value credited as a result of a YES outcome are subject to a temporary transfer restriction and may not be withdrawn by the User pending expiry of the Dispute Period.

b. Final Settlement. If no review is initiated during the Dispute Period, the Market Outcome becomes final and binding upon expiry of the Dispute Period, and any transfer restrictions on credited Settlement Value are lifted. Once final Settlement is reached, the Market Outcome cannot be reversed except in the limited circumstances described herein.

8. Market Outcome Determination and Review

8.1 Initial Determination. OKX will determine the Market Outcome for each Event Contract based on the Expiration Value obtained from the Underlying at Expiration.

8.2 Review Trigger. OKX may initiate a Market Outcome review process to determine if:

(a) there is material ambiguity or dispute regarding the applicable Expiration Value;

(b) the Underlying was subject to a material error, disruption, or manipulation at or around the Expiration;

(c) an extraordinary event has occurred that renders an automatic determination inappropriate or unreliable; or

(d) review is otherwise required to preserve the integrity and orderly settlement of the Events Contract.

8.3 Outcome Review Committee. OKX may establish an Outcome Review Committee (or equivalent body) with authority to review and determine the final Market Outcome in disputed or ambiguous cases. The Outcome Review Committee shall use its reasonable judgment and act in good faith in making its determination. The determination of the Outcome Review Committee shall be final and binding on all Users.

8.4 Settlement Price Data Fallback. Where OKX Spot Index Price data is unavailable or incomplete at the Expiration, the following fallback logic applies:-

a. For Price Up Down Contracts (60-point Settlement Observation Window): (i) if thirty (30) or more of the sixty (60) required second-level index price data points are available, the Settlement Price is the arithmetic mean of the available data points; (ii) if fewer than thirty (30) data points are available, OKX will automatically suspend settlement for that Events Contract, initiate the Dispute Period, and refer the matter for manual review and determination in accordance with this Clause 8.

b. For Price Above Contracts (60-point Settlement Observation Window as described herein): (i) if thirty (30) or more of the sixty (60) required data points are available, the Settlement Price is the arithmetic mean of the available data points; (ii) if fewer than thirty (30) index data points are available but thirty (30) or more OKX spot last-trade-price data points are available for the same window, OKX will use the arithmetic mean of spot last-trade prices as a fallback Settlement Price; (iii) if fewer than thirty (30) spot data points are also available, OKX will suspend settlement, initiate the Dispute Period, and refer the matter for manual review.

In all cases of suspension, affected Users will be notified promptly and transfer restrictions on profitable positions will remain in place until final Settlement is determined. OKX may also: (i) apply an alternative reference price or methodology as specified in the Contract Specifications or as determined in OKX's reasonable discretion; (ii) delay or suspend settlement pending resolution of the disruption; or (iii) cancel or void the relevant Event Contract, in each case acting in good faith. OKX will notify affected Users of any such determination via its notifications system as soon as practicable.

8.5 No Liability for Good Faith Determinations. Subject to Clause 11, OKX shall not be liable to any User for any determination made in good faith in respect of a Market Outcome, whether under the initial determination process or following a Market Outcome Review.

9. Position Limits

9.1 Position Limits. OKX may impose maximum net Position limits ("Position Limits") on the aggregate open interest that any User may hold in any single Event Contract. Position Limits are expressed as a maximum USD-equivalent USDT value of open positions per event and are configurable by OKX. Additional or different Position Limits may apply by jurisdiction as required by applicable law. Applicable Position Limits will be published on OKX and may be amended from time to time.

9.2 Enforcement. Where a User's Position exceeds an applicable Position Limit, OKX may take such steps as it reasonably deems necessary to bring the Position within permitted levels, including cancelling open orders and closing Positions at prevailing market prices. OKX shall not be liable for any loss suffered by a User as a direct result of enforcement action taken under this Clause.

9.3 Aggregation. For the purposes of applying Position Limits, the Platform may aggregate Positions held by accounts that it reasonably determines to be related, affiliated, or acting in concert.

13. Risk Disclosure

EVENTS CONTRACTS INVOLVE SIGNIFICANT FINANCIAL RISK. YOU MAY LOSE THE ENTIRE AMOUNT INVESTED. THESE PRODUCTS MAY NOT BE SUITABLE FOR ALL INVESTORS. DO NOT TRADE WITH FUNDS YOU CANNOT AFFORD TO LOSE.

13.1 Binary Outcome Risk. Events Contracts have a binary settlement structure. If your prediction is incorrect, you will lose the full amount invested in a Buy / YES Position (or, for a Sell / NO Position, an amount equal to the Settlement Value less the consideration initially received). There is no intermediate recovery of losses.

13.2 Price Above Contracts are European-style instruments and settle only on the Expiration Date. You cannot realise a gain or limit a loss on a Price Above Contract by reference to the price of the Underlying prior to the Expiration Date.

13.3 Liquidity Risk. There is no guarantee that a liquid market will exist for any Events Contract at any time. You may be unable to close a Position at a favourable price, or at all, in illiquid market conditions. Illiquidity may result in your Position being held to Expiration.

13.4 Reference Price Risk. Settlement is dependent on the availability and accuracy of the Underlying. In the event of disruption to the Underlying at or around the Expiration, settlement may be delayed, modified, or cancelled as described herein.

13.5 Underlying Volatility. The price of the Underlying may be highly volatile and subject to rapid and unpredictable changes. Past performance of the Underlying is not indicative of future results, and no representation is made as to any price movement.
