The Polymarket arbitrage loop is not a single opportunity.
It is a repeating structural system behavior created by intraday repricing and fragmented execution conditions.
Loop Structure
- mispricing appears across correlated markets
- liquidity reacts unevenly
- execution partially corrects imbalance
- micro-imbalances reappear
- cycle repeats under latency pressure
inefficiency does not disappear — it oscillates under continuous correction pressure
Why Most People Reject It
Static Model Bias
People expect one-shot arbitrage closure.
Visibility Bias
Only successful executions are visible; failures are not.
Time Compression Error
Correction is assumed to be instant.
System-Level Drivers
The loop exists due to three structural forces:
- information propagation delay
- liquidity fragmentation
- execution latency on Polygon
equilibrium is never fully reached — only approximated
Execution Flow (Real System Behavior)
- Market A reprices first
- Market B lags behind
- Spread opens
- Arbitrage bots detect divergence
- Execution begins
- Partial fills reduce imbalance
- Residual gap remains
- New information triggers repricing
Why It Becomes a System Loop
The key property is not mispricing.
It is recurrence under continuous market activity.
- information asymmetry persists
- liquidity is uneven
- execution is non-instant
Failure Conditions
Even when the loop exists, profit collapses due to:
- slippage exceeding spread
- gas costs removing edge
- latency producing stale entries
- partial fills breaking hedges
the loop exists, but profit is not guaranteed
Where the Loop Breaks
The system collapses when:
- liquidity synchronizes too quickly
- latency advantage disappears
- competition saturates execution
arbitrage compresses into near-zero margin competition
Why It Still Exists
The loop persists because:
- new markets continuously form
- information is never perfectly synchronized
- execution remains probabilistic
- narrative shocks arrive unevenly
efficiency is continuously recreated at system edges
Intraday → Arbitrage → MEV Spine
Where real-time information becomes liquidity and probability movement.
Execution Systems LayerHow arbitrage is executed under intraday repricing conditions.
MEV Execution LayerCompetition over ordering, latency, and settlement extraction.
Final Interpretation
The Polymarket arbitrage loop is:
- real
- unstable
- continuously self-correcting
It is not a static strategy.
It is a system artifact inside intraday execution pressure.
