Polymarket Arbitrage Loop: Why It Fails in Practice

A deep breakdown of how Polymarket arbitrage loops form, persist, and collapse under real execution conditions on Polygon.

April 25, 2026

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)

  1. Market A reprices first
  2. Market B lags behind
  3. Spread opens
  4. Arbitrage bots detect divergence
  5. Execution begins
  6. Partial fills reduce imbalance
  7. Residual gap remains
  8. 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


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.
