Signal World Cup Knockout Trading Championship

The Signal World Cup Knockout Trading Championship (the “Competition”) gives eligible participants an opportunity to compete for a share of a total prize pool of $10,000 USD by trading designated FIFA World Cup prediction markets through the Signal platform during the knockout stages of the Tournament.

Participants will be ranked primarily according to their Competition Profit and Loss (“Competition PnL”), subject to the eligibility, trading-volume, compliance, and anti-abuse requirements set out in these Terms & Conditions.

The Competition is operated by Monorail / Signal (“Operator”). It is a promotional campaign intended solely for eligible Signal users and is void where prohibited by law.

This Competition is not sponsored by, endorsed by, administered by, or affiliated with FIFA, Polymarket, or any tournament organizer.

For purposes of these Terms:

• —“Competition Period” means the period beginning at 26 June 2026 08:00 UTC and ending at 19 July 2026 23:00 UTC.
• —“Tournament” means the FIFA World Cup 2026.
• —“Eligible Market” means a FIFA World Cup prediction market expressly designated by the Operator as eligible for the Competition.
• —“Eligible Trade” means a valid buy or sell transaction in an Eligible Market that is executed through the Signal platform during the applicable Competition or Stage period; is recorded as completed by the Operator’s systems; is attributable to the participant’s verified Signal account; and is not excluded under these Terms.
• —“Trading Volume” means the aggregate notional value of Eligible Trades completed through the Signal platform. Both valid purchases and valid sales may count toward Trading Volume. Canceled, failed, rejected, reversed, refunded, fraudulent, manipulative, abusive, wash, self-directed, circular, coordinated, duplicated, or otherwise invalid transactions do not count.
• —“Competition PnL” means the net profit or loss attributable to a participant’s Eligible Trades during the Competition Period, calculated in accordance with Section 8.
• —“Stage” means one of the following Tournament knockout stages: Round of 32; Round of 16; Quarter-finals; Semi-finals; or Final.
• —“Stage Period” means the period assigned by the Operator to a particular Stage, as published in the Competition Rules or Competition interface.
• —“Verified Account” means a Signal account that has completed all verification and compliance requirements requested by the Operator and remains in good standing.
• —“Prize Schedule” means the final allocation of the $10,000 USD prize pool among Stage and any other announced prize categories, as published before the Competition begins and incorporated into these Terms as Schedule A.

To participate, a user must:

• —be at least eighteen (18) years old or the legal age of majority in their jurisdiction, whichever is higher;
• —have a valid Verified Account;
• —maintain their Signal account in good standing from entry through winner verification and prize payment;
• —be legally permitted to access and use Signal and the related prediction-market services;
• —be located in an eligible jurisdiction throughout their participation;
• —comply with applicable laws, regulations, sanctions requirements, these Terms, the Signal Terms of Service, and the Signal Privacy Policy;
• —satisfy all valid-entry and Trading Volume requirements; and
• —not otherwise be prohibited or restricted by the Operator.

Employees, contractors, officers, directors, agents, and immediate family or household members of the Operator may not participate unless expressly approved in writing by the Operator and permitted by applicable law.

The Operator may restrict, deny, suspend, or terminate participation for legal, compliance, sanctions, security, operational, integrity, or risk-management reasons. The Competition is void where prohibited by law.

Participation is prohibited from any country, territory, state, province, region, or other location designated by the Operator or a relevant prediction-market service as blocked; restricted; frontend-restricted; close-only; sanctioned; embargoed; unavailable for opening new positions; or otherwise ineligible for participation or trading.

The current Polymarket geographic-restriction documentation and geoblock API may be used by the Operator as authoritative operational sources for determining whether related prediction-market services are available from a participant’s detected location.

The Operator may also rely on:

• —internal compliance systems;
• —IP geolocation;
• —device and network information;
• —account and KYC information;
• —residency information;
• —sanctions screening;
• —source-of-funds information; and
• —any other reasonable legal, compliance, or risk controls.

Passing a geoblock or location check does not guarantee eligibility. The Operator may apply restrictions that are broader or stricter than those applied by a third-party provider. Failing a geoblock or compliance check may result in denied entry, disqualification, account restrictions, or loss of prize eligibility.

Participants may not use VPNs, proxies, onion routers, remote desktops, false location information, false residency information, false identities, or any other method to conceal their location or circumvent geographic restrictions.

The Operator may update restricted jurisdictions at any time where required by law, regulation, sanctions obligations, third-party availability, or platform risk controls.

To submit a valid Competition entry, a participant must, before 19 July 2026 23:00 UTC:

• —create and maintain a Verified Account in good standing;
• —register for or opt into the Competition through the official Competition entry flow;
• —deposit at least $100 USD or USD equivalent into their Signal account;
• —complete any required identity verification, anti-money laundering, sanctions, source-of-funds, residency, or other compliance checks;
• —trade Eligible Markets during the Competition Period; and
• —satisfy the applicable minimum Trading Volume requirements.

Deposited funds, to the extent not committed to trades, fees, or other activity, remain the participant’s funds and are not paid to the Operator as an entry fee.

Trading may result in loss of some or all funds used by the participant. All trading losses, spreads, fees, slippage, gas fees, transaction costs, and other costs incurred while participating are solely the participant’s responsibility.

Each verified individual is limited to one Competition entry, regardless of the number of accounts, wallets, devices, addresses, or identities they control or use. Late, incomplete, duplicated, fraudulent, manipulated, or otherwise invalid entries will not qualify.

Only Eligible Markets expressly designated by the Operator will count toward Competition PnL, Trading Volume, Stage results, or prize eligibility. The Operator will publish or display the list of Eligible Markets through official Signal channels or the Competition interface.

Unless otherwise stated, Eligible Markets may include markets relating to matches or Tournament outcomes occurring during the Round of 32, Round of 16, Quarter-finals, Semi-finals, and Final.

The following do not count unless expressly approved by the Operator:

• —trades executed outside Signal;
• —trades executed before the applicable Competition or Stage period;
• —trades executed after the applicable cutoff;
• —trades in non-designated markets;
• —transferred or imported positions;
• —referral rewards, bonuses, rebates, airdrops, or promotional credits;
• —deposits, withdrawals, or wallet transfers;
• —trades canceled, rejected, reversed, refunded, or voided;
• —wash, self, circular, coordinated, or artificial trades; and
• —transactions the Operator cannot reliably verify.

The Operator may correct the classification of a market or trade where it was mistakenly included or excluded. The Operator will not retroactively exclude a valid market solely to alter a participant’s ranking, except where necessary to correct an error, respond to a voided or malformed market, address abuse, or comply with law.

Participants must reach the following cumulative Trading Volume thresholds by the end of each applicable Stage Period:

These thresholds are cumulative across the Competition. They are not additional amounts required for each Stage. For example, a participant must have completed at least $1,500 in total eligible Trading Volume by the Round of 16 deadline, rather than $1,000 plus an additional $1,500. Both valid buys and valid sells may count toward Trading Volume.

A participant who fails to satisfy a Stage threshold by the applicable deadline may be ineligible for:

• —a prize relating to that Stage; or
• —any other prize category for which the threshold is a stated condition.

The Operator must publish each Stage cutoff before the relevant cutoff occurs. The Operator may amend a Stage period or Trading Volume deadline where Tournament scheduling, postponed matches, technical failures, market availability, or other material circumstances make the original deadline impracticable. Any material amendment will be communicated through official Signal channels and will not be made solely to favor or disadvantage a particular participant.

8.1 General calculation

Competition PnL will be calculated by the Operator based only on Eligible Trades and Eligible Markets. Unless otherwise specified in Schedule A, Competition PnL will equal:

• —realized profit or loss from Eligible Trades closed or settled during the applicable measurement period; plus
• —the marked value of any open eligible positions at the applicable ranking cutoff; minus
• —the participant’s cost basis for those positions; minus
• —any trading fees or transaction costs expressly included by the Operator in Competition PnL.

Deposits, withdrawals, transfers, referral rewards, promotional rewards, rebates, airdrops, unrelated account activity, and the value of positions acquired outside the Competition do not increase Competition PnL.

A participant’s Competition PnL for a Stage is the sum of the profit or loss across that Stage’s fixtures, derived from the participant’s Eligible Trades as set out above. Competition PnL is shown on the leaderboard as “Points.”

8.2 Open positions

Open positions at a Stage or Competition cutoff will be valued using the price or valuation methodology recorded by the Operator’s systems at the cutoff. The Operator may use the prevailing executable market price; a reasonable midpoint or mark price; the official settlement value; a time-weighted or liquidity-adjusted value; or another consistently applied valuation methodology described in Schedule A. The same methodology will be applied consistently to similarly situated participants.

8.3 Settled, voided, and disputed markets

A settled market will be valued according to its final settlement.

If an Eligible Market is canceled, voided, malformed, disputed, reversed, incorrectly resolved, or unavailable, the Operator may exclude that market and its associated trades; apply the market’s official refund or void treatment; recalculate affected rankings; delay final results until resolved; or use another fair and consistently applied treatment. Official Tournament results may be used as a factual reference, but market settlement and Competition PnL are determined under the applicable market rules and the Operator’s published calculation methodology.

8.4 Negative PnL

Competition PnL may be negative. A participant who has a negative PnL may remain ranked unless the applicable prize category requires positive PnL.

8.5 Currency conversion and rounding

USD-equivalent values, currency conversions, token valuations, and rounding will be determined using the Operator’s systems and consistently applied methodology. Displayed figures may be rounded for presentation. Rankings will be determined using the underlying unrounded values.

8.6 Adjustments

The Operator may adjust Competition PnL to correct:

• —calculation errors;
• —duplicate or missing transactions;
• —reversed, failed, voided, or invalid trades;
• —incorrect market data;
• —wash or manipulative activity;
• —abuse, collusion, or self-dealing; or
• —other activity improperly included in or excluded from a participant’s results.

The Operator may maintain a live or periodically updated leaderboard showing information such as:

• —rank;
• —Competition PnL (shown as Points);
• —Trading Volume;
• —position changes; and
• —recent eligible activity.

Leaderboard data is provisional and may be delayed, incomplete, rounded, inaccurate, or subject to adjustment. A displayed rank does not create an entitlement to a prize.

Final rankings will be determined only after:

• —the Competition Period ends;
• —relevant markets have been valued or settled as required;
• —Trading Volume requirements have been verified;
• —eligibility and compliance reviews have been completed;
• —suspected abuse has been investigated; and
• —calculation errors and adjustments have been resolved.

The Operator’s final certified standings, rather than any provisional leaderboard display, determine prize eligibility.

The total Competition prize pool is $10,000 USD. Prizes are allocated among Stage winners and any other category expressly described in the Prize Schedule.

The complete Prize Schedule must be published before the Competition begins and will form part of these Terms as Schedule A. The Prize Schedule must specify each prize category; the amount assigned to each category; the number of winners; the ranking or performance required; any minimum positive PnL requirement; any applicable Stage or Trading Volume requirement; tie treatment; and whether a participant may win more than one prize.

The aggregate value of all prizes will not exceed $10,000 USD unless the Operator expressly increases the prize pool. No unannounced prize category will reduce an already published prize allocation.

Where no participant satisfies the requirements for a prize category, that prize will be treated as stated in Schedule A, which may provide that it is not awarded; rolls into another category; is divided among other eligible winners; or is otherwise reallocated according to a predetermined rule.

All prizes are determined per Stage. A Stage winner is the participant with the highest Competition PnL from Eligible Trades on that Stage’s fixtures during the relevant Stage Period. The Operator may also publish a combined standings view across all Stages for information only; this combined view does not by itself confer any prize.

To receive any prize, a participant must:

• —remain eligible under these Terms;
• —have a Verified Account in good standing;
• —satisfy the applicable deposit and Trading Volume requirements;
• —complete all requested verification and compliance checks;
• —comply with the Competition rules; and
• —have no disqualifying abusive, manipulative, fraudulent, or invalid activity.

A participant is not guaranteed a prize merely because they appear on a provisional leaderboard.

Where two or more participants have the same underlying unrounded Competition PnL for a prize position, ties will be resolved in the following order, unless Schedule A states otherwise:

• —highest eligible Trading Volume during the relevant measurement period;
• —earliest time at which the participant completed all applicable entry and Trading Volume requirements; and
• —if a tie remains, equal division of the affected prize among the tied participants, unless prohibited by the Prize Schedule or applicable law.

The Operator may not rely on rounded leaderboard values when determining whether a tie exists.

The Operator may review the trading and account activity of any participant at any time. The trading activity of all potential prize winners will be reviewed before final certification and payment. Such review may include:

• —account ownership;
• —identity and residency;
• —IP addresses and geolocation;
• —devices and technical identifiers;
• —wallet ownership and funding;
• —trading patterns;
• —trade counterparties;
• —timing and pricing;
• —related accounts or wallets;
• —referral relationships;
• —deposits and withdrawals;
• —source of funds;
• —compliance history; and
• —any indicators of wash trading, self-trading, coordination, manipulation, or artificial volume.

Potential winners may be required to provide documents, explanations, wallet attestations, transaction records, tax information, or other evidence reasonably requested by the Operator. Failure to provide requested information within the stated timeframe may result in disqualification or forfeiture of prize eligibility.

The following are prohibited:

• —multiple accounts, identities, wallets, or entries controlled by one individual;
• —account sharing or use of another person’s identity;
• —wash trading; self-trading; circular trading;
• —artificial volume generation; Sybil activity;
• —collusive, coordinated, or prearranged trading;
• —manipulation of markets, prices, liquidity, PnL, or leaderboard position;
• —trading between accounts or wallets under common control;
• —use of bots, scripts, automation, or automated trading systems for Competition participation, unless expressly permitted in Schedule A;
• —exploitation of bugs, vulnerabilities, stale pricing, calculation errors, or unintended platform behavior;
• —false, misleading, fraudulent, or deceptive information;
• —circumvention of geographic, compliance, account, trading, or eligibility restrictions; and
• —any activity that undermines the fairness, integrity, or intended operation of the Competition.

Ordinary trading with an unknown counterparty through a shared market or order book will not, by itself, constitute prohibited coordinated trading.

The Operator may:

• —investigate activity;
• —exclude trades from Trading Volume or PnL;
• —correct rankings; disqualify entries;
• —suspend or terminate accounts;
• —void prize eligibility;
• —withhold prize payment while a review is pending; and
• —take any other action permitted under the Signal Terms of Service or applicable law.

A prize may be permanently denied only where the Operator determines that the participant was ineligible, failed verification, breached these Terms, or engaged in prohibited conduct.

Before receiving a prize, a potential winner may be required to:

• —complete identity verification;
• —complete sanctions and anti-money laundering screening;
• —provide proof of age, identity, location, and residency;
• —provide source-of-funds or wallet information;
• —provide tax documentation;
• —demonstrate compliance with these Terms; and
• —cooperate with fraud, trading-integrity, or security reviews.

Failure to complete verification within 30 days after notice may result in disqualification, unless the Operator grants an extension. Prizes will be paid in USDC within 30 days after final verification and certification.

The Operator may delay or withhold payment where reasonably necessary to complete a review or comply with law, sanctions, court orders, regulatory obligations, or platform risk controls. Winners are responsible for all taxes, duties, reporting obligations, and governmental charges associated with a prize. The Operator may withhold amounts where required by law.

Prediction-market trading involves significant risk and uncertainty. Participants acknowledge that:

• —they may lose some or all funds used for trading;
• —trading volume is not equivalent to profit;
• —higher Trading Volume may increase financial risk and transaction costs;
• —market prices may be volatile or illiquid;
• —trading may involve spreads, fees, slippage, gas fees, and other costs;
• —the Competition does not guarantee a prize, profit, or return;
• —participation does not constitute financial, investment, legal, or tax advice; and
• —each participant is solely responsible for their own trading decisions and risk management.

Participants should not trade funds they cannot afford to lose.

To the maximum extent permitted by law, the Operator is not responsible for:

• —platform downtime or latency;
• —API, data-feed, oracle, or market failures;
• —blockchain congestion;
• —failed, delayed, rejected, or reverted transactions;
• —wallet, network, device, browser, or connectivity issues;
• —market suspension, closure, cancellation, voiding, or delayed settlement;
• —third-party service interruptions;
• —inaccurate or delayed leaderboard displays;
• —failed or delayed deposits or withdrawals;
• —user error; or
• —any technical issue affecting a participant’s ability to enter, trade, meet Trading Volume requirements, or appear on the leaderboard.

Participants are responsible for completing requirements sufficiently before applicable deadlines. Nothing in this section excludes liability that cannot lawfully be excluded.

The Operator may modify, suspend, postpone, restrict, or cancel the Competition where reasonably necessary due to:

• —changes in law or regulation;
• —sanctions or compliance requirements;
• —Tournament scheduling changes;
• —market or liquidity-provider availability;
• —technical failures; security incidents;
• —fraud, manipulation, or integrity concerns;
• —force majeure; or
• —other circumstances outside the Operator’s reasonable control.

The Operator may amend administrative or technical rules where necessary, but will not materially reduce an earned or already published prize solely for commercial convenience. Material changes will be communicated through official Signal channels. If the Competition is canceled, the Operator will determine the treatment of prizes in accordance with applicable law and any cancellation methodology stated in Schedule A.

To the maximum extent permitted by law, the Operator and its affiliates, officers, employees, contractors, service providers, and partners will not be liable for:

• —trading or market losses;
• —fees, spreads, slippage, gas fees, or transaction costs;
• —missed trading or prize opportunities;
• —technical or third-party failures;
• —Tournament or market changes;
• —incorrect provisional leaderboard information; or
• —indirect, incidental, consequential, special, exemplary, or punitive damages arising from participation.

The Competition and leaderboard are provided on an “as is” and “as available” basis without warranties of uninterrupted availability, accuracy, merchantability, fitness for a particular purpose, or non-infringement. Nothing in these Terms excludes liability that cannot lawfully be excluded.

The Operator may collect, use, review, and retain information necessary to administer the Competition, including:

• —identity and account information;
• —trading and transaction information;
• —wallet information;
• —IP address and geolocation;
• —device and technical identifiers;
• —compliance and sanctions information;
• —referral information; and
• —prize and tax information.

Such information may be used for eligibility verification; leaderboard calculation; fraud and abuse prevention; compliance screening; winner certification; prize payment; security; and legal or regulatory obligations. Personal information will be processed in accordance with the Signal Privacy Policy and applicable law.

Where permitted by law, winners may be asked to participate in reasonable promotional activity relating to the Competition. Any use of a winner’s legal name, likeness, image, voice, or testimonial will be subject to applicable law and any additional consent required by the Operator. Public leaderboard usernames and Competition results may be displayed as part of normal Competition administration.

These Terms will be governed by the laws of The British Virgin Islands, without regard to conflict-of-law principles. Any dispute arising from the Competition will be resolved in accordance with the dispute-resolution provisions of the Signal Terms of Service, unless Schedule A or applicable law requires otherwise. To the maximum extent permitted by law, participants waive participation in class, collective, or representative proceedings.

By registering for, entering, or participating in the Competition, a participant agrees to:

• —these Terms & Conditions;
• —Schedule A;
• —the Signal Terms of Service;

• —official Competition instructions published by the Operator.

If a participant does not agree, they must not participate. The Operator’s decisions regarding eligibility, trade classification, PnL calculations, Trading Volume, rankings, abuse investigations, and prize certification are final and binding, subject to applicable law and any manifest calculation error.
