Questions, answered plainly.

No. Clauseground is a market-intelligence and decision-support service. It shows current prices, margin-removed market probabilities, a separate model view, and the uncertainty behind each comparison. It can surface a potential opportunity, but it does not present disagreement as proof that a bet will win.

No. Football outcomes are uncertain, prices move, and models can be wrong. Clauseground cannot guarantee an outcome or a profit. Its purpose is to make the evidence and trade-offs clearer so that you can make your own decision — including deciding not to bet.

Market numbers come from timestamped odds collected from supported venues. Clauseground removes the margin from a complete reference market, then shows that market view separately from its statistical model. The product labels the source and update time wherever the underlying data is available.

No. Probabilities are calculated by structured pricing and modelling tools. The AI analyst retrieves those outputs, compares them, and explains them in plain language. It is instructed not to invent prices, probabilities, results, or data sources.

Displayed odds include a bookmaker margin. Fair, or no-vig, probability is the market-implied probability after that margin is removed across every outcome in the same market. It is a cleaner view of what that market is pricing, not a promise about what will happen.

The model and the market use different inputs and update in different ways. A difference can reveal something worth investigating, but it can also mean the model is missing information or the price has moved. Clauseground treats disagreement as a question, not automatic evidence of an edge.

Closing line value compares the price we published with the de-vigged closing price of the sharp reference market for the same selection: the closing fair probability minus the implied probability of the published price, so a positive value means the published price was better than the closing fair line. It is one way to evaluate whether a process found favorable prices, but it is not proof of future profit and must be read with the sample size, the interval and the collection method.

Measured, yes — and it is the largest effect we can demonstrate. Across 27,323 completed matches with a full set of closing prices (11 August 2026), books held 5.62% of the average 1X2 market; taking each outcome at whichever surveyed book priced it highest left −0.14%, a difference of 5.77 points of margin. Per selection the best surveyed price sat 6.83% above the market average, and 34,141 outcomes cleared a de-vigged sharp-book estimate at the best price against 795 at the average — a factor of 42.9×. That is a property of the market, not a record of returns: the best price is taken across all surveyed books, including books that limit winning accounts and quotes that were never simultaneously obtainable, so read it as an upper bound on what a real bettor captures rather than as money made. Clauseground does not currently claim a proven historical edge, and none of this says a bet will win.

De-vig is short for removing the vigorish — the bookmaker’s own margin, which is built into every displayed price. Removing the bookmaker margin from a complete market so that its probabilities sum to 100%; Clauseground currently removes it proportionally, dividing each raw implied probability by their total. Worked through: prices of 2.00, 3.60 and 4.00 imply 50.0%, 27.8% and 25.0%, a total of 102.8%; removing that margin proportionally gives approximately 48.6%, 27.0% and 24.3%. Those are no-vig market probabilities — a cleaner reading of what that market is pricing, not a prediction of the result.

Expected value, usually written EV, is the arithmetic that puts a price and a probability estimate on the same scale. What one unit staked at a given price returns on average if the estimated probability is correct — an arithmetic consequence of a price and an estimate, never a forecast of profit. It is stated per unit staked, and it inherits every weakness of the estimate behind it: if the probability is too high, so is the EV, and a large number is more often a sign that the estimate is wrong than that the price is. Clauseground does not currently claim a proven historical edge, and a positive EV figure is a reason to look harder at the evidence rather than a reason to expect a win.

The highest decimal odds Clauseground has collected for an outcome across the venues it surveys, which is not necessarily a price any one account could have taken. Every price on a match page names the venue that quoted it and the time it was collected, so it can be checked at the venue before any decision. The surveyed set includes books that limit winning accounts, books unavailable in some jurisdictions, and quotes that were never simultaneously obtainable — so read the best price as the ceiling of what comparing venues is worth, not as a price you are guaranteed to be able to take.

Clauseground does not currently connect to your betting accounts or place bets for you. It may display supported sportsbook or exchange prices when those feeds are available. Venue coverage varies by competition and market, and each displayed price should be checked before acting.

The live Markets page is the source of truth for current coverage. Coverage depends on reliable fixture, odds, and modelling inputs, so a competition is shown only when usable data is available. Clauseground is expanding beyond its original 2026 World Cup development dataset into major club competitions.

Update frequency depends on the competition, market, and upstream feed. Clauseground shows timestamps rather than promising a universal real-time interval. If a price looks stale or a key input is missing, verify it at the venue before making a decision.

Yes. Clauseground has a permanent free tier, and every paid plan can be upgraded, downgraded, or cancelled at any time from your account. Cancellations take effect at the end of the current paid period — you keep paid access until then — and plan changes are prorated. Nothing is ever charged without an explicit, opt-in subscription.

Yes. A paid plan renews automatically at the end of each billing period — monthly or annually, whichever you chose at checkout — until you cancel. Cancelling from your account stops the next charge and leaves your plan running to the end of the period you have already paid for. The free tier never renews into a charge, and nothing is charged without an explicit subscription.

Yes, within 14 days. Any charge is fully refundable for 14 days, including a renewal you did not intend — no reason required and no proportion withheld. After 14 days a charge is not automatically refundable, but ask us anyway. Statutory rights of withdrawal or cancellation where you live apply in addition to this. The full billing terms are on the terms page.

No. Clauseground provides research and decision support, not personal betting, financial, legal, or investment advice. You remain responsible for checking the price, understanding the risk, complying with local law, and deciding whether to act.

You may use Clauseground only where doing so is lawful and only if you meet the legal gambling age that applies to you. Availability of a website does not mean betting is legal in your location. Check your local rules before using betting-related information.

No. Clauseground does not accept deposits, hold funds, operate a market, or place wagers on your behalf. It is an analysis product. Any action at a sportsbook, exchange, or prediction market is separate and remains your responsibility.
