# GOP uses 'Nuclear Option' to break filibuster by December 31, 2026? This is a vote-result test, not a test of rhetoric about changing Senate rules. Nomination votes are explicitly outside the relevant legislative process. Canonical article: https://www.homeincomelab.com/stories/will-the-gop-use-nuclear-option-to-break-filibuster Publisher: The Outlook By: The Outlook editorial desk Category: Politics Analysis as of: 2026-10-04T09:57:48.323Z Decision guide market prices observed: 2026-10-04T09:57:48.323Z Published: 2026-10-04T09:57:48.323Z ## Quick answer This is a vote-result test, not a test of rhetoric about changing Senate rules. The leading open contract, “December 31, 2026”, was priced at 3.45% for Yes in the October 4 snapshot. The Senate must pass a legislative cloture motion with fewer than three-fifths of senators voting Yes.

Nomination votes are explicitly outside the relevant legislative process. At the October 4, 2026 market snapshot, December 31, 2026 carried a 3.45% Yes price.

Advice-and-consent confirmations do not count. [1](https://polymarket.com/event/will-the-gop-use-nuclear-option-to-break-filibuster) The selected child’s cutoff is December 31, 2026 at 11:59 p.m. ET. [1](https://polymarket.com/event/will-the-gop-use-nuclear-option-to-break-filibuster) ## Evidence for and against the leading outcome An official legislative cloture result meeting the lower vote-count condition supports Yes. A nomination precedent, threatened rules change or unsuccessful motion can fail despite a nuclear-option headline. The next useful checks are legislative versus nomination calendar; passed cloture motion; recorded number of affirmative votes. 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 $561,671 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.
