Weather edge bot leads strong day; 32GB repo flagged malware

Weather Arbitrage, Copy Trading, and a 32GB Red Flag

A strong day for open-source intelligence: eight new repos surfaced, five cleared for cloning, and three security flags worth your immediate attention. The standout find is a fundamental weather edge strategy that is more rigorous than most retail quant tooling on Polymarket right now.

New Bots: What We Found

**`polymarket-weather-edge`** is the most interesting strategy of the day. It pulls live METAR station data alongside Open-Meteo forecasts, runs them through a Gaussian probability model to estimate the true likelihood of a temperature threshold being hit, and bets NO when the implied market probability is higher than the model says it should be. This is a clean fundamental edge — not sentiment, not latency. If you trade weather markets, clone this and audit the model calibration before deploying capital.

**`polytrackers-polymarket-copy-trading-skill`** is worth cloning for a different reason. It identifies large, historically profitable wallets and lets an AI agent replicate their positions. It ships with a $10k mock wallet for paper trading and an MCP interface for Claude integration. The copy-trading approach carries obvious risks — whale wallets can be wrong, and lag kills the edge — but as a research and signal-generation tool it has clear utility.

**`go-clob-client`** is infrastructure, not strategy, but serious bot builders running Go stacks should note it. If you want sub-millisecond order placement and reliable orderbook streaming outside the Python ecosystem, this is your foundation layer.

**`polyterm`** is a CLI dashboard for market monitoring and order placement. No alpha embedded, but if you operate manually or want a lightweight interface for rapid execution without a browser, it is solid tooling.

The fifth worth-cloning repo, **`news-orderbook-arbitrage`**, is flagged as monitor rather than immediate-clone. The strategy — parsing news feeds and placing orders inside 200ms — is sound in concept, but execution infrastructure requirements are steep. Unless you already have co-location or near-exchange latency, this one benchmarks your setup more than it generates edge.

⚠️ Security: Three Alerts, One Critical

**Critical — do not clone:** A 32GB Polymarket bot repository is circulating. No legitimate trading bot requires 32 gigabytes. This is consistent with loader malware or a data exfiltration tool packaged as a bot. Treat it as confirmed hostile until proven otherwise. If you have already downloaded it, audit your environment immediately.

**Fake stars flag:** A Polymarket Telegram bot is showing 168 stars against 134 forks — an inverted ratio that is a classic signal of star-farming campaigns. The repo has no corroborating evidence of legitimate use. Stars are purchased; forks are harder to fake at scale. Avoid.

**Spam flag:** One additional repo surfaced with a garbled username and no verifiable authorship or commit history. No strategy logic visible. Skip it.

Alpha Signals: Research Worth Reading

Three academic papers hit the queue today. The most operationally relevant: a paper distinguishing payoff-space no-arbitrage from protocol-executable no-arbitrage in prediction markets, using Polymarket's negative-risk markets as the core example. The key finding — that apparent arbitrage violations in winner-takes-all markets may not be exploitable before settlement due to position transformation constraints — has direct implications for anyone running cross-market arbitrage bots. Know what you cannot actually capture before you build the strategy around it.

A second paper frames Polymarket's exhaustive, mutually exclusive condition sets and how arbitrage emerges structurally from those relationships. Pair it with the first paper.

The LLM-based merger arbitrage paper is interesting but further from immediate deployment.

What to Watch

Spain's block of Polymarket and Kalshi over licensing is the regulatory story of the week — watch for copycat actions in other EU jurisdictions. The HN thread on the Iran missile story death threats is noise for trading purposes but a signal that market resolution disputes are becoming more visible and contentious. Resolution risk on geopolitical markets deserves a wider discount than most models apply. Monitor your exposure accordingly.
