NegRisk Arbitrage Theory Meets Five Cloneable Bots
Two new research papers formalize why NegRisk arbitrage is harder to execute than it looks on paper, distinguishing theoretical no-arbitrage conditions from what the protocol will actually let you trade. Meanwhile, five cloneable repos dropped this week covering whale tracking, live baseball markets, and two distinct arbitrage scanners.
NegRisk Arbitrage Is Theoretically Sound and Practically Constrained — Here's Why Both Matter
The most important finding today isn't a bot or a wallet. It's a conceptual clarification that should change how you size your NegRisk arb positions. Two research papers circulating in the alpha feed draw a hard line between *payoff-space* no-arbitrage and *protocol-executable* no-arbitrage on Polymarket. The short version: a deterministic payoff identity can exist mathematically while being physically untradable due to position transformation constraints. If you've been modeling NegRisk arb assuming clean round-trip execution, you may be overestimating edge. Read the papers before you allocate.

New Bots: 5 Worth Cloning, 1 to Monitor
**polymarket-whalewatch** is the most immediately useful repo this cycle. It aggregates large fills, split-buy accumulation patterns, fresh-wallet entry signals, and smart-money consensus into a single informed-trader detection layer. If you're not running whale tracking already, this is the fastest path to standing one up. Clone and instrument.
**poly-baseball** targets live in-game markets using what appear to be statistical models over pitch counts and live scores to identify mispriced lines. Baseball markets on Polymarket are thin and move fast — a model with even modest accuracy on in-game events has real edge in low-liquidity windows. Worth cloning if you have any sports-data pipeline you can feed it.
**arbitrage** and **poly-arb** both target NegRisk/maker arbitrage but from different angles. The first uses asyncio for high-throughput opportunity detection and simulation across NegRisk markets. The second focuses on maker-side arb, scanning for spread discrepancies between counterparties and simulating fills. Given today's research findings on protocol-executable constraints, treat both as simulation tools first — validate that your intended trades are actually executable before going live. Run them in paper mode, log the opportunities they flag, and manually check settlement paths.
**polymarket-trading** gets a *monitor* verdict rather than a clone. It applies convex optimization to multi-market portfolio allocation for HFT arbitrage, which is sophisticated, but the complexity warrants more review before you trust it with capital. Watch for updates and community validation.

Security: No Malware, But Star Farming Is Active
No confirmed malware this cycle — good. But fake-star campaigns are running on at least two repos: the **Polymarket Telegram Bot** and **CloddsBot AI trading agent**. Both show inflated star counts inconsistent with commit history and fork activity. Do not use GitHub star count as a proxy for repo quality in this ecosystem. The **panel-polymarket** repo is straight spam — garbled username, no substantive code. Flag and ignore.

Alpha Signals: Research Over Live Trades
No live wallet alpha or confirmed edge trades surfaced today. The three alpha signals are all research-tier. The most actionable is the **LLM-based merger arbitrage forecaster** — a long-context reasoning system trained over merger agreement documents that reportedly outperforms human forecasters on deal outcome prediction. Merger markets on Polymarket are undertraded relative to their information density. If you can adapt this approach or access the model outputs, there's a real application here.
The two NegRisk structure papers are required reading if you're running any arb strategy touching linked binary markets. The condition-set exhaustiveness requirement creates pricing anomalies when probabilities sum incorrectly — that's a systematic inefficiency, but one that requires careful execution modeling to capture.

What to Watch
Spain's Polymarket/Kalshi block and the Iran missile story death threats both hit HN front page hard today. Regulatory pressure in the EU is real and accelerating — if you're operating with European counterparty exposure, start thinking about that now. The **Nothing Ever Happens** bot hitting 471 HN points is a useful reminder that naive base-rate strategies still attract attention; someone will productize it properly eventually.
Watch the **arbitrage** and **poly-arb** repos for community forks over the next 72 hours. First movers on NegRisk tooling tend to cluster fast.
