PredictionToolkit
What is SpreadCore?
Use the terminal to compare Polymarket sports prices with bookmaker lines before kickoff or during play. The site names Pinnacle, Stake, Duel, Empire, Roobet, BC.Game, Mellstroy and SX among its comparison sources. Inspect Polymarket depth, choose a market or limit order and calculate the bookmaker stake, with a displayed ROI adjusted for fees and rebates.
The documented flow executes the Polymarket leg and tells you the stake to place with the bookmaker. It does not establish atomic execution across both venues: partial fills leave directional exposure, and stale odds can change the hedge. Bookmaker voids and different settlement rules can break the apparent match after entry. Maker rebates also depend on the venue program and fill eligibility. Access, crypto billing and event notifications run through Telegram.

Workflows with SpreadCore
Review a hedge setup
Compare exact event rules, calculate stakes and confirm available prices at both venues.
Place and hedge
Check how much of the Polymarket order actually filled, then place the bookmaker stake needed for that filled amount. Record the confirmed price and terms on both sides rather than assuming the initial hedge calculation describes the final position.
Reconcile results
Compare both outcomes, fees and void treatment rather than relying only on the scanner’s initial ROI.
Pricing and total cost
Prepaid access and crypto billing are handled by the official Telegram manager bot.
