Announcer markets

Beyond the fight outcome contracts, Kalshi offers a category exclusive to the platform: markets tied to specific words and phrases called by the broadcast announcers during each fight. For the Moicano vs. Duncan main event, traders are currently pricing “Knockout / Knock Out” at 57% and Moicano’s nickname “Money” being mentioned at 50%, with $12,534 in volume across 17 markets.

The Yakhyaev vs. Ribeiro bout has its own announcer market set with “Knockout / Knock Out” at 51% and “Train / Trained / Training” — a nod to Yakhyaev’s credentials — at 60%. These markets settle fast and add a layer of in-broadcast trading that no other prediction market platform currently offers.

Markets with the most volume for tonight

Duncan is 55% on Kalshi with $187,191 traded — the most volume on the card. He’s 15-2, won four straight, and finished three of those by submission. Moicano is 20-7-1, has lost two in a row, and turns 37 this month. The market’s read is straightforward.

The co-main is trading at 52-48 — the closest market on the card. Jandiroba is the slight favorite at 52% despite coming off a loss to Dern. Ricci has won her last fight and holds the ranking edge she needs to be dangerous on the feet. The near-even split reflects what the fight actually is: two top-10 strawweights with no obvious stylistic mismatch.

If you’re building toward $10 before the main card, the three highest-confidence markets on the card right now are Yakhyaev at 90% ($166,695 vol), Bekoev at 85% ($115,984 vol), and McMillen at 86% ($130,970 vol). The Pat vs. Petersen market is sitting at 51-49 — essentially a coin flip — which makes it the most interesting even-odds contract on the undercard for anyone looking for value beyond the main event.

New customers only. 18+, US only. $1 minimum deposit. $10 bonus unlocks after $10 in cumulative trades. Sports market availability varies by state. Full terms at kalshi.com.
