Reading the matched-bet card
A field-by-field guide to the matched-bet card in the Arbitrage Finder — the two legs, recommended stakes, modelled profit, profit percentage, the live game status, and the max-bet constraint.
What the card shows
Every row in the Arbitrage Finder is one matched bet: a pair of opposing sides spread across two different sportsbooks whose combined prices are structured to return a profit on either outcome, when both legs are placed at the displayed prices and settle. Before you place either leg, read the card so you know exactly what you are committing to.
The card is divided into two halves — one per leg — inside a shared panel. The fields on each leg are the same, so reading one teaches you to read both.
The two legs
A matched bet has two sides. SmartStake calls them the promo bet (the primary side, shown first) and the hedge bet (the offsetting side). In a pure arbitrage both are real-money bets at independent sportsbooks; neither is a free bet. Taking the matched bet creates two separate wagers that you track and grade independently.
Each leg row shows:
- Bet name — the selection: the team, player, or outcome you are backing on that side, including the line (spread points or totals number, if applicable). Displayed in title case.
- Book — the sportsbook carrying that leg. A bookmaker icon appears to the left of the name. Clicking the bet name opens the book directly in a new tab so you can confirm the price before you stake.
- Odds — the current price at that book in your preferred odds format (American, decimal, or fractional). This is the live price SmartStake last read; always verify it at the book before placing.
- Rec Bet — the recommended stake for this leg, in dollars, calculated from your configured bet size. The two stakes are not equal: the hedge-side stake is set so that whichever leg wins, the net return is the same. If the book publishes a maximum bet limit, a compact figure appears beneath the stake labeled M, indicating the ceiling you cannot exceed.
The profit summary
At the left edge of the card, a badge shows the modelled profit percentage for the matched bet. For arbitrage bets this is the return on total stakes if either leg wins — the same modelled number on either outcome, because that is what makes the bet an arb. A higher percentage means a larger modelled return relative to total outlay.
The profit percentage is derived from the formula: (payout on winning leg) / (total stakes across both legs) − 1. It is displayed to two decimal places on desktop.
For middles — a variant where both legs can win simultaneously — an additional chip appears showing the potential dollar profit if the middle lands. That scenario is covered in Middles: how to win both sides.
Verify odds before you place
Odds move quickly. The card reflects the last scraped price, not a guaranteed quote. Always confirm the price is still live at each book before committing your stake. A bet placed at worse odds than those shown may no longer be profitable.
Live game status
When the matched bet's game is already in play, the card shows a live game status in place of the start time — the current score and game state, refreshed alongside the odds. The compact line on the card carries the period or inning and the running score (shown away–home, matching the matchup). Open the card's detail view for the live game details tailored to the sport.
What you see depends on the sport:
- Baseball — the count and outs, runners on, the batter, and hits and errors.
- Basketball — timeouts left and team fouls.
- Football — the current down and distance.
- Soccer — the latest match event and minute, extra time, and shootout goals.
- Tennis — who is serving, with the current game's points in the running score.
Hockey carries only the period and running score.
For arbitrage this matters more than for most bets: live markets move and suspend constantly — between innings, at a timeout, during a review — and an arb only holds if both legs are still live. The game status is a quick read on whether play is active or stopped before you try to place both sides.
The max-bet constraint
When a sportsbook publishes a bet limit on a selection, the card shows that limit as M: $X beneath the recommended stake. This matters because the math behind the recommended stake assumes you can place the full calculated amount. If the max is below the recommended stake, you either reduce both legs proportionally to stay within the limit or skip the opportunity — placing only one leg leaves you unhedged and exposed to a full-stake loss.
Reading the card before placing
Work through the card in this order. First confirm the two bet names are truly opposing outcomes on the same market and event. Then check that the odds at each book still match what the card shows. Next note the two recommended stakes — the larger number is typically the hedge leg. Finally look at the profit badge: if it still reads positive after confirming live prices, the arb is valid and you are ready to proceed.

- Odds, prices, expected value, conversion rates, and profit figures shown are estimates based on the last data we retrieved. They can change at any time — confirm the current price at the book before you bet, as odds may move and entry errors can occur.
- Arbitrage and matched betting carry execution risk: a price can move or a leg can be rejected before you place both sides, and sportsbooks may limit or void bets. A favorable outcome is not guaranteed.
- Using a “sharp” book as a fair-value reference is a modeling choice, not a statement of accuracy. Review a book’s record yourself and anchor on the books you trust.
