PredictIt match — what traders need to know about parity
If you searched for “predictit match” you’re likely comparing matched positions or looking for cross-platform parity between PredictIt and Polymarket. PredictIt is a US-centered prediction market with its own matching rules; it is separate from Polymarket’s CLOB architecture. For arbitrageurs, the practical question is where price divergences appear and how quickly you can capture them. PolyArb monitors Polymarket intra-market spreads and routes trades with a $7.62 minimum guaranteed edge and low-latency execution.
What a PredictIt match actually is
PredictIt operates under US regulatory constraints and matches orders in its own order book or broker-facilitated fills. A “match” commonly means a buy and a sell filled against each other at an agreed price. PredictIt’s structure, fees, and eligibility differ from Polymarket, so identical market prices are uncommon. PredictIt markets can show persistent spreads due to lower automation and different user bases.
For traders, the implication is execution model mismatch. Polymarket runs a Central Limit Order Book on Polygon; PredictIt uses a different clearing and custody model. That matters for latency, fees, and the sorts of arbitrage you can reliably execute.
Where Polymarket and PolyArb fit
Polymarket is a gasless, Polygon-based CLOB with binary and multi-outcome markets. PolyArb is a third-party bot built for intra-Polymarket arbitrage: it watches for price sums below $1.00 across outcomes and executes buys plus CTF operations to lock edge. PolyArb is non-custodial, live today, and advertises 40ms latency versus ~800ms for free bots.
PolyArb includes Telegram and Discord alerts and guarantees a $7.62 minimum edge per trade as part of its product terms. That guarantee is part of the service offering and should be read alongside the bot’s execution and fee policies.
Risks and practical limits
Even when a textbook arbitrage appears, it isn’t unconditional risk-free profit. Risks include resolution disputes via UMA, partial fills and slippage, fee changes, settlement timing, and smart-contract considerations. Polymarket also geo-restricts some users, which affects who can trade.
PolyArb reduces execution latency and automates split/merge/redeem flows, but you still face the platform risks above. Successful use requires monitoring fills, orderbook depth, and current fee schedules.
When cross-platform matching matters
If you’re looking for price convergence between PredictIt and Polymarket, cross-platform arbitrage is a different playbook: timing windows are longer and you must handle off-platform custody and settlement differences. PolyArb focuses on intra-Polymarket opportunities where the book mechanics and CTF token flows are unified.
For traders comparing platforms, evaluate latency, fees, regulatory access, and whether you need automated tooling to capture fleeting spreads.
