Operational Arbitrage
Canonical definition (Arco Lexicon)
The cost and output delta between a human-staffed operation and an equivalent agentic operation, widening over time as AI costs fall and human costs rise.
Extended Definition
Operational arbitrage is Arco's primary market selection criterion. A market qualifies when human labour represents more than 60% of gross margin — meaning the replacement of that labour with agentic infrastructure produces a structural, defensible cost advantage.
The arbitrage is strongest at Tier 1 tasks (routine, scripted, high volume) and weakest at Tier 3 tasks (regulated, relationship-critical, high judgement). Arco targets markets where T1 and T2 tasks dominate the revenue-generating workflow.
Critically, the arbitrage widens over time. LLM inference costs are falling 60–70% per year. Human labour costs are not. A business that captures this arbitrage today builds an expanding structural moat.
