The leading open contract, “December 31”, was priced at 10.5% for Yes in the October 4 snapshot. An officially announced U.S.–Cuba agreement on trade, tariffs, sanctions or the embargo qualifies; it need not take effect yet.

Both parties must announce it, or overwhelming credible reporting must confirm a finalized agreement.

[1](https://polymarket.com/event/us-x-cuba-economic-deal-by) ## Evidence for and against the leading outcome Matching official acceptance of the same finalized trade-related agreement supports Yes. Ongoing talks, unilateral policy changes or incompatible descriptions of the terms can fall short. The next useful checks are statements from both governments; finalized terms and covered trade topic; announcement date versus effective date. The linked primary references make the process and named data source inspectable.

Their Yes prices should not be added into a single winner probability, and the highest Yes price is not automatically the most informative question. The event had approximately $442,154 in total traded volume at observation. That is a record of turnover across this event, not a count of distinct people, a search-volume estimate or proof that every child contract is easy to trade. The analytical quote is fixed to the timestamp shown here; later live prices can differ.

A view merely agreeing that this is plausible does not show that the price understates it. The probability, rule and remaining time all have to be compared.
