Weather Bots Mature; Kalshi-Polymarket Arb Bridges Emerge

GitHub Intelligence — 2026-07-03

Weather Markets: The Quietest Edge Getting Loudest

The most technically credible cluster in today's feed centers on Polymarket temperature markets. **RiekertQuant/polymarket-weather-bot-poc** leads with 21 stars and 5 forks — meaningful traction for a niche strategy — and has been actively maintained since January 2026. Its sibling entry, **BallesJr/polymarket-weather-edge**, takes a more specific approach: it explicitly targets the NO side of overpriced temperature markets, combining live METAR observations (actual airport weather station readings) with Open-Meteo forecast data fed into a Gaussian probability model.

This is a real strategy with real edge potential. Polymarket temperature markets are resolved against specific weather station readings, and retail participants routinely misprice tail risk in either direction. A bot that systematically identifies YES-side overpricing and fades it with calibrated NO positions is a structurally sound approach. The fact that two independent developers are converging on similar architectures — and that the older one is gaining forks — suggests the edge is real enough to attract replication but not yet crowded enough to be fully arbitraged away. Operators active in weather markets should audit their current pricing against METAR sources directly.

Cross-Platform Arbitrage: Kalshi Enters the Picture

**Juanp2389/Kalshi-trade-bot** is the most strategically significant new entry today. It explicitly targets BTC 15-minute markets on both Kalshi and Polymarket simultaneously, scanning for price gaps and executing paired trades. This is the first confirmed public repository in this feed history that bridges the two platforms in a single execution layer.

This matters for Polymarket operators on two fronts. First, if this strategy gains adoption, price discovery on Polymarket's short-duration crypto markets will increasingly be imported from Kalshi and vice versa, compressing spreads. Second, it signals that the arbitrage window between regulated (Kalshi) and decentralized (Polymarket) venues is being actively hunted. Operators running manual or semi-manual crypto market strategies should assume faster price equilibration going forward.

**kenfri13/polymarket-arbitrage-trading-bot** covers similar ground — 15-minute Up/Down crypto markets via the Gamma API with configurable hedge thresholds — and has been in development since March 2025, making it one of the longer-running projects in today's feed. Its longevity suggests the 15-minute crypto arb niche has sustained profitability over multiple market cycles.

Copy Trading Infrastructure Expanding

Three separate copy-trading repositories appeared or were updated today: **kalliimmunosuppressive504/polymarket-copy-trading-bot** (TypeScript, interval polling), **UnitedStars111/polymarket-copy-trading-bot** (TOML config, multi-category), and **gabrieltoribiopereira/panel-polymarket** (a read-only public dashboard for a copy-trading simulation). The dashboard entry is notable — it suggests at least some operators are building transparency layers around their bots, possibly for performance verification or future commercialization.

Copy trading pressure on Polymarket's top wallets is not new, but the tooling is becoming more accessible. If you are a high-performing operator, assume your on-chain activity is being mirrored by at least one automated process.

Security Flags

Two repositories warrant caution. **King102681/polymarket-bot** carries a file size of approximately 6.2 GB with no description — an anomalous ratio that suggests either bundled binary payloads or dataset dumps embedded in the repo. Do not clone or execute. **bit-nexusxtitmtdsuy/Polymarket_Bot** has 32 stars and 17 forks with a generic description; the username pattern and star-to-description ratio are consistent with reputation-farmed repositories sometimes used to distribute compromised trading scripts. Treat as untrusted until audited.

Auspex: Crypto Market Screener Worth Watching

**gorillachimps/auspex** describes itself as a screener and trading frontend specifically for Polymarket's crypto markets, featuring distance-to-trigger metrics against live resolution sources and resolution-confidence scoring. At 368 MB it appears to be a substantive build rather than a skeleton project. The 0% fee claim likely refers to its own interface layer, not Polymarket's underlying fees. This is the kind of tooling that can meaningfully improve execution timing on crypto price markets — worth monitoring for a public release or demo.

Bottom Line

Weather and short-duration crypto markets are the two verticals attracting the most serious automated attention right now. Cross-platform Kalshi-Polymarket arb is an emerging structural shift. Audit your exposure in both areas.
