venue-arb

Venue-arb is the most honest cross-venue arbitrage repo in this batch. It explicitly frames itself as research, runs read-only, and ships a live public dashboard (venue-arb.samuel-shlee.com), which is a strong signal the author has actually validated the pipeline end-to-end rather than vibe-shipping. Scope: match Kalshi contracts against Polymarket equivalents, compute spreads, surface dislocations for manual review. It also touches trade.xyz stock perps and pre-IPO perps, which suggests the author is thinking about the broader event-contract universe rather than just K↔P. The hard part of cross-venue arb is always market matching — title NLP, settlement-rule equivalence, expiration alignment — and this repo is one of the few that centers that problem instead of hiding it. ~3.3MB Python codebase, coherent author, live demo link, no malware fingerprints. 0 stars is the only real weakness, but that's typical for a research repo published as a byproduct of personal work. Best fit for anyone running or researching K↔P arb — clone it for the matching logic and the spread calculator, then build your own execution layer against Kalshi's API. Not useful for people who just want a live bot; this is a discovery tool. Final verdict: worth cloning as a research scaffold; the market-matching heuristics alone are worth the read.
