Arbitrage Bot Guide
@PropprArbBot finds mathematical price discrepancies across 100+ bookmakers - place bets on all outcomes for a balanced return at the captured prices \u2014 provided every leg is actually placed, and prices can move before you get them on.
What is Arbitrage Betting?
The Setup
Different bookmakers price the same outcome differently. When the combined implied probability across all outcomes falls below 100%, the odds allow a balanced return across every outcome.
The Lock
Bet365 Over 2.5 @ 2.10 + Pinnacle Under 2.5 @ 2.05. Stake £49.40/£50.60 = £100 total. Return at those prices: £103.74. Margin: 3.60%.
Custom Arb Example Output
💰 CUSTOM ARBITRAGE OPPORTUNITY 💰Bet #1: £41.86 @ 2.50
Bet #2: £58.14 @ 1.80
Total Stake: £100.00
💰 Return at the captured prices: £104.65 - Margin £4.65 (4.65%)
Three Stake Scenarios in Every Alert
Every alert prints all three splits together - there is nothing to switch. Pick the line that suits your risk appetite and place those stakes.
Standard
Equal profit regardless of outcome. The safest split.
RF High
Break even on the likely outcome, big profit if the underdog wins.
RF Low
Break even on the unlikely outcome. Moderate, steady profit on the likely winner.

Key Features
Automatic Stake Calculation
No manual math. The bot calculates optimal stakes for all three scenarios. Edit any stake or odds - the other side auto-recalculates. Bookmaker link buttons open each site; you place the bets yourself.
LAY Betting & Exchange Support
Betfair Exchange, BetfairIT, Smarkets, Kalshi, Limitless, Polymarket and SxBet. A 2% commission (default, editable per exchange) is automatically applied to any exchange leg - back or lay - in all profit calculations.
Live Arbs (Premium, Opt-In)
In-play surebets with their own minimum-margin floor, separate from prematch. Alerts show the current score, and a "⏸️ ON BREAK/PAUSE" banner flags paused matches where odds are frozen. Choose Break/Pause-only or all in-play in /settings.
Middle Arbs
"💰💎 MIDDLE ARBITRAGE OPPORTUNITY 💎💰" alerts flag line gaps where BOTH bets can win - e.g. Over 2.0 / Under 3.0. A middle is NOT arbitrage: only the gap outcome wins both legs, and every other outcome loses one. The alert shows the cost when the gap misses alongside the return if it lands.
Prediction Markets & Liquidity Capping
Polymarket and Kalshi legs show cents pricing like "2.38 (42¢)" with USD stakes and a ⚡️ Polygun quick-buy button. Exchange liquidity is displayed per leg, and stakes are automatically capped: "⚖️ Total stake capped by liquidity: £X".
/custom - Create Your Own
Found a boosted odds offer? Send /custom and answer three questions (Bet #1 odds, Bet #2 odds, total stake). The bot builds the full arb calculation instantly - great for promotions and price errors.
50+ Sports Covered
While football is the core, arbs are found across Tennis, Basketball, Ice Hockey, American Football, Baseball, Cricket, and Esports (Dota 2, CS:GO, LoL).
Speed is Critical
Arbitrage opportunities typically last 60–120 seconds before bookmakers correct their lines. Enable Telegram push notifications for @PropprArbBot and have both bookmaker accounts open when you place bets. Most profitable arbs (above 2%) vanish within 60 seconds.
