# Which airlines will announce bankruptcy by December 31? A bankruptcy-announcement market is not a general vote on whether the selected airline has an attractive business. Its decisive evidence is a definite authorized announcement, so financing stress and legal filing are separate steps.

The leading open contract, “Frontier Airlines”, was priced at 10% for Yes in the October 4 snapshot. An authorized definitive announcement of a bankruptcy filing, intended filing or completed filing qualifies even if the filing occurs later.

Its decisive evidence is a definite authorized announcement, so financing stress and legal filing are separate steps. At the October 4, 2026 market snapshot, Frontier Airlines carried a 10% Yes price. Other open contracts included JetBlue at 6.15%; Allegiant at 2.75%.

The statement must come through official channels or representatives, with credible-reporting confirmation allowed by the rules. [1](https://polymarket.com/event/which-airlines-will-announce-bankruptcy-by-december-31) The selected 2026 contract ends December 31, 2026 at 11:59 p.m. ET. [1](https://polymarket.com/event/which-airlines-will-announce-bankruptcy-by-december-31) ## Evidence for and against the leading outcome A definitive company announcement that funding or restructuring plans now require a filing supports Yes. New financing, an out-of-court restructuring, or continued consideration without a definite announcement can leave the contract at No. The next useful checks are official company statement and exact legal entity; definitive decision versus contingency; the selected child deadline. 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 $155,414 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.
