Prediction market on polymarket_us. If John Castaneda wins by submission in the John Castaneda vs Alatengheili UFC fight, scheduled for September 26, this market will settle to Yes. A submission is defined as a fight-ending stoppage in which John Castaneda's opponent verbally or physically taps out, is rendered unconscious by a chokehold, or the referee stops the fight because the opponent is unable to escape a submission hold and is at risk of serious injury. Outcome sourced from the relevant governing body or event organizers. If the bout is declared a No Contest by the governing body due to an accidental foul, a pre-existing injury, or any other circumstance that prevents a definitive result from being determined, this market will settle to fair market price, as determined by the Exchange. Any post-fight changes to the official result, including overturned decisions or retroactive No Contest rulings following a failed drug test, will not affect settlement once the market has already settled. If the UFC fight is postponed or delayed within two weeks of the original date, the market will remain open and will settle once the fight is complete. Cancellation or rescheduling beyond the two-week window results in resolution at the last fair market price.
