What happened
Menifield broke his thumb in round one. The bone was visibly protruding and he was bleeding heavily by round two. The cageside doctor checked the hand between rounds and cleared him to continue. He fought the rest of the way with it and took the split decision at 5:00 of round three, scored 28-29, 29-28, 29-28 in the UFC's order. It opened the main card.
Baraniewski was 9-0 coming in. Every one of those wins was a first-round finish, and he had never been past round one in his professional career. UFC 331 was the first time anyone made him fight for fifteen minutes, and he lost for the first time doing it. He leaves at 9-1 with the finishing streak and the unbeaten record gone in the same night.
Menifield is 38. He is 19-6-1 now and 4-1 in his last five, and this was his second straight upset win. He opened the main card as a +200 underdog against a man the market expected to close the show early. He won it in the rounds his opponent had never visited, then let two of three judges see it his way.
What the market did
The lowest trade printed at 1¢ and the best offer was 2¢, so this one is close to honest for a buyer.
Menifield went into the fight at 27c (+200). While the bout was live the best offer on his contract reached 2c, timestamped 2026-09-20 01:48Z. That is the market pricing him at effectively no chance of hearing a decision go his way. He settled at 100 when the cards were read. It is the cheapest anything on the UFC 331 card could be bought.
Other sites will quote 1c. That was a seller hitting the bid. The best offer never went below 2c, so one cent is close to honest for a buyer, but it is not the number. Across that whole minute 165,165 contracts changed hands at a volume-weighted average of 68.65c, so almost all of that trading happened near 69 cents, nowhere near the low.
What each stake returned
| Stake | Contracts at 27¢ | Returned | Contracts at 2¢ | Returned |
|---|---|---|---|---|
| $100.00 | 370 | $370.00 | 5,000 | $5,000.00 |
| $200.00 | 740 | $740.00 | 10,000 | $10,000.00 |
| $5,000.00 | 18,518 | $18,518.00 | Not fillable. That is 250,000 contracts, 151% of everything that traded in that minute at any price. | |
The right half is the best offer that existed while the fight was live. Getting filled there still depends on size being available, which a candlestick cannot tell you. Where a stake would have been a large share of that minute's entire volume, the table says so rather than printing a number nobody could have collected. Volume on that minute was 165,165 contracts. Returns are gross of the Kalshi trading fee and are hindsight: they show what a price paid once the result was known, not what anyone should stake next.
