The UFC Middleweight Champion 2026 market asks who holds the 185-pound belt when the year ends. Sean Strickland reclaimed the title from Khamzat Chimaev by split decision at UFC 328 on May 9, 2026, his second reign, with Nassourdine Imavov first in line and Chimaev eyeing a move to light heavyweight. Twelve fighters carry contracts across Kalshi and Polymarket. The live board above ranks the current cross-platform prices. The market resolves December 31, 2026.
The UFC middleweight belt changed hands twice in nine months, and the 2026 market is priced for a division still finding its footing. Sean Strickland walked into UFC 328 an underdog and walked out a two-time champion, upsetting Khamzat Chimaev on the scorecards. The question the UFC Middleweight Champion 2026 market answers is direct: does Strickland still hold the belt when the year ends, or does one of the contenders behind him take it first. The live board above ranks every fighter with a live contract across Kalshi and Polymarket.
Strickland reclaimed the title at UFC 328 on May 9, 2026 at the Prudential Center in Newark, edging Chimaev by split decision on cards of 48-47, 47-48, 48-47. It was his second run with the belt, and it came against a champion most of the room favored. As the reigning champion, Strickland is the market's default answer to the UFC Middleweight Champion 2026 question, because the contract resolves on who is wearing the belt on the final day of the year rather than on any single fight.
The open variable on Strickland is timing. He was suspended indefinitely on medical grounds after UFC 328, so the UFC cannot book his first defense until he is cleared. The longer that clearance takes, the fewer chances a challenger has to take the belt before December 31. See the live board above for where his contract sits today.
Nassourdine Imavov has built the clearest contender case in the UFC Middleweight Champion 2026 field. The French striker known as "The Sniper" rides a five-fight win streak, headlined by a second-round knockout of former two-time champion Israel Adesanya at UFC Saudi Arabia in Riyadh on February 1, 2025, and a win over rising contender Caio Borralho later that year. He has publicly pushed for the next title shot and says the promotion promised him the fight.
If Imavov is booked against Strickland and wins before year-end, the board flips to him. That is the whole shape of his contract: a title fight that is widely expected but not yet formally on the calendar. His current price on the live board reflects both his standing in line and the uncertainty over when the champion returns.
Khamzat Chimaev took the belt from Dricus Du Plessis at UFC 319 in Chicago on August 16, 2025 with a lopsided decision, then lost it to Strickland at UFC 328 without a successful defense. Since that loss he has signaled a move up to light heavyweight, a jump that would pull him out of this race entirely unless he stays at 185. Traders can track that division separately on the UFC Light Heavyweight title market.
Du Plessis sits behind him as a former champion trying to climb back. He returns on July 18, 2026 against Kamaru Usman in Oklahoma City, and a statement win starts his path to a rematch, though the runway to reclaim the belt by December 31 is short. Caio Borralho is the next name down, ranked in the division's top tier after a seven-fight UFC run that ended with a loss to Imavov, then a rebound decision over Reinier de Ridder at UFC 326 on March 7, 2026. Every other fighter on the live board above trades in the low single digits.

Sean Strickland, who reclaimed the belt by split decision over Khamzat Chimaev at UFC 328 on May 9, 2026, is the board favorite as the reigning champion. Nassourdine Imavov, on a five-fight win streak, is the leading challenger.
Watch for the UFC to book Strickland's first title defense once he is medically cleared, and watch the July 18, 2026 bout between Dricus Du Plessis and Kamaru Usman, whose winner re-enters the title picture. Any belt change in the fall would reprice the entire board.
