Coherence Arbitrage Bots Surface as Spain Blocks Polymarket

Coherence Arb Goes Mainstream — And the Regulators Noticed

The most actionable development today is the convergence of a new open-source repo and two independent research papers all pointing at the same exploitable structure: Polymarket's negative-risk linked binary markets contain coherence violations that are protocol-executable, not just theoretical. If you are not already running a scanner on mutually exclusive market clusters, today is the day to start.

New Bots: 4 Worth Cloning

**polymarket-coherence** is the lead find. The repo targets coherence violation detection and arbitrage research — the exact mechanism two papers published this cycle formalize. One paper distinguishes payoff-space no-arbitrage from protocol-executable no-arbitrage, arguing Polymarket's market structure makes the gap observable. The second analyzes how exhaustive/mutually-exclusive condition sets create cross-market arbitrage. Clone this repo and read both papers in parallel; the strategy surface is well-defined and the academic backing is unusually strong.

**postbot** runs market-making and event-driven trading on social-media post count prediction markets — a niche vertical that requires low latency on social API feeds. Viable for operators already paying for data infrastructure; the market-making angle means edge comes from spread capture, not directional calls.

**polymarket-whalewatch** implements whale and smart-money flow following with a feedback loop that grades its own alert reliability over time. The self-grading mechanism is the differentiating feature — most flow-following bots degrade silently as whale behavior shifts. Worth cloning for the architecture even if you rebuild the signal logic.

**arb_polyweather** uses AI-assisted forecasting to trade weather event outcome markets against posted prices. Narrow vertical but structurally clean: ground truth resolves objectively, historical data is deep, and meteorological model outputs are freely available. Execution risk is low if your data pipeline is solid.

**polymarket-tui** is flagged monitor-only. Terminal interface utility, useful for manual oversight of automated positions but not an alpha source on its own.

Security: Malware and Spam Campaigns Active

Four alerts today, and the malware situation warrants a hard stop before you clone anything.

Confirmed 460KB cloned malware template repos are in circulation. The payload pattern is a templated bot repo that looks functional but exfiltrates keys or injects malicious trades. Verify file sizes and diff against known-clean repos before executing anything locally. Sandbox first, always.

Two separate spam campaigns are also running: garbled usernames with zero stars are being used to seed fake repos into search results, and a fake star-farming operation is inflating star counts on several Polymarket trading bot repos to manufacture social proof. Do not use star count as a trust signal this week. Check commit history depth, contributor diversity, and code quality directly.

Alpha Signals

The M&A forecasting paper is operationally interesting for Polymarket traders: a long-context LLM system trained on merger documents outperforms traditional M&A outcome prediction methods. Polymarket runs active merger outcome markets. If you can replicate even a degraded version of the document-ingestion pipeline using public SEC filings and press releases, you have a directional edge on those markets that does not depend on flow or arb structure.

No confirmed live wallet signals with verified edge today. The five new wallets logged are under observation; nothing tradeable yet.

Strategy Intelligence

One new strategy documented: the "Nothing Ever Happens" approach — a bot that systematically buys No on non-sports markets — surfaced on Hacker News with 471 points. It is a real strategy with a real theoretical basis (resolution bias toward non-events), but it is now public enough that the edge will compress. If you were running a variant quietly, expect more competition on the No side of ambiguous event markets.

What to Watch

Spain's block of Polymarket and Kalshi is the regulatory story to track. It does not affect most operators today, but it establishes a precedent that other EU jurisdictions will cite. Watch for liquidity shifts on markets with heavy European participation. The death-threat HN story at 1,606 points is a platform reputation event — monitor for any policy response from Polymarket that tightens account verification or position limits.
