Palmeiras vs. Cerro Porteño Leads Cross-Venue Gaps with 1076% Nominal Spread

### Execution Intel While the nominal spreads on today's board look highly lucrative, execution requires extreme caution. Two major structural issues stand out for desk traders looking to route capital: 1. **Severe Expiry Mismatches:** * **GA-04 & GA-06 House Elections:** Polymarket contracts expire on November 3, 2026, while Kalshi contracts do not expire until November 3, 2027. This represents a 12-month capital lockup differential. Do not treat this as a clean correlation play unless you are prepared to carry the Kalshi leg for an extra year. * **French Presidential Candidates:** There is a 13-month settlement gap between Polymarket (April 2027) and Kalshi (May 2028). 2. **Stale/Settled Markets (Palmeiras vs. Cerro Porteño):** The top-performing spread on paper lists Polymarket expiry on May 21, 2026, and Kalshi on June 04, 2026. Given today is June 13, 2026, these markets are likely already settled or in resolution. Inspect actual market states before deploying any automated size. 3. **Liquidity Constraints:** None of the listed opportunities report active daily volume. This points to thin order books. If you try to cross the spread with market orders, slippage will instantly erase these theoretical yields. Work limit orders patiently on both sides.
