How matching works

EventGraph runs a background matching service that compares market titles across all four platforms using fuzzy text similarity. Markets scoring above the threshold are stored as matched pairs.
The default threshold for the Compare endpoint is match_score ≥ 0.55.

​
Understanding gap_cents

When the same event trades at different prices on two platforms, gap_cents shows the price difference in percentage points (0–100 scale):
A gap_cents of 5.2 means Platform A prices the event 5.2 cents higher than Platform B.

​
Feasibility score

Not every spread is exploitable. The feasibility_label considers the minimum available volume: The estimated_slippage field estimates execution cost based on available depth.
Prediction market arbitrage involves execution risk, platform withdrawal times, counterparty risk, and regulatory differences between platforms. EventGraph provides data only — not trading advice.
