A different kind of edge
Model-free
No forecasts, no alpha. The edge is pure internal price inconsistency — the market contradicting itself.
Market-neutral
Every trade is a hedged basket with a locked, non-negative payoff regardless of the game result.
Multi-venue
Watches the same market on Polymarket and Kalshi and arbs disagreements between independent books.
AI-classified
A free-tier LLM maps any market into the lattice, so the same engine generalizes to any sport or event.
Three layers of coherence
Complementary
If ask(YES) + ask(NO) < 1 on one market, buy both sides for a guaranteed dollar.
Dutch book
The 30 title outcomes are exhaustive. If Σ ask(YES) < 1, buy them all for under a dollar.
Implication
Champion ⊑ conference. When P(champion) > P(conference), short the dear leg, buy the cheap one.
a exceeds its conference price b, buy NO(champion) at (1−a) + YES(conference) at b. The minimum payout in every outcome is $1 (the "wins title but not conference" case is impossible) for a cost of (1−a)+b — a guaranteed a − b, with no view on the game.Same market, two venues
Polymarket and Kalshi each run the 2026 NBA Champion market on independent order books. When they disagree beyond fees, that gap is a locked cross-venue arbitrage — shown live below.
