UFC 329: Kai Kamaka III vs. Luke Riley Prediction July 11

The Kai Kamaka III vs. Luke Riley prediction leans toward the fight going over 1.5 rounds, with the YES outcome carrying a 56.5 percent probability on Polymarket heading into UFC 329. Kamaka III brings a decision-heavy style into this featherweight prelim, and the market has steadily drifted toward the longer fight scenario after a meaningful 24-hour price move.

The momentum composite tells a clear story here. The YES price held flat in the last hour but climbed six percent over 24 hours, and a trend score of 10.86 confirms the market is still building conviction rather than cooling off. This fight lands on the preliminary card at UFC 329 on July 11, 2026, at T-Mobile Arena in Las Vegas. Total lifetime volume on the market sits at $1,661, a modest but directionally consistent pool that reflects a niche prelim prop with real money behind the over.

How the Kai Kamaka III vs. Luke Riley Market Resolves

The YES outcome resolves when the fight extends past the 1.5-round mark, meaning it survives beyond the midpoint of Round 2. A finish in Round 1 or early Round 2 locks in the NO outcome at 43.5 percent. The market also offers alternative props, including fight-ending method markets such as KO/TKO, submission, and goes-the-distance lines, as well as fighter-specific finish props.

• YES (Fight goes over 1.5 rounds): 56.5%
• NO (Fight ends by 1.5 rounds): 43.5%

Kai Kamaka III is the fighter whose profile most supports the longer-fight case. Kamaka carries a 2-2-1 UFC record and has resolved five of his seven UFC bouts by decision. His overall pro record stands at 18-7-1, with just two career KO/TKO victories — a 29 percent finishing rate. Kamaka defeated Dakota Hope by split decision on April 4, 2026 in a late-notice lightweight bout, extending his run of competitive, distance-going fights. His chin and cardio have held up in grinding three-round contests, which is precisely what the YES market is pricing.

Market Signals and Form

The momentum composite here points in one direction. The YES probability climbed six percent over the prior 24 hours and has now touched its market high at 56.5 percent, with the trend score at 10.86 confirming that recent buying has not yet reversed. The catalyst is almost certainly Kamaka’s confirmed April 2026 decision win, which reinforced his decision-fighter identity and gave bettors a fresh data point before this featherweight prelim.

Total lifetime volume of $1,661 with $94 changing hands in the last 24 hours reflects a low-volume prop market, but liquidity sits at $12,340, meaning the market can absorb meaningful size without the price moving erratically. The depth here is healthy relative to the volume, suggesting the current 56.5 percent price is structurally stable.

Spread and moneyline data for the individual fighter winner market are available as separate Polymarket props under the Kai Kamaka III vs. Luke Riley event umbrella. Among correlated markets, this fight shares event-family exposure with other UFC 329 props — a strong performance from Kamaka would likely lift his fighter-specific finish props as well. Correlations with unrelated domains such as the MLS Cup or MLB World Series do not apply here and are disregarded.

• YES probability: 56.5%, up six percent over 24 hours with trend score 10.86 confirming momentum
• Kamaka UFC record: 2-2-1, with five of seven UFC bouts resolved by decision
• Kamaka overall finish rate: 29% KO/TKO across 26 pro bouts
• Last result: Kamaka defeated Dakota Hope by split decision on April 4, 2026
• Liquidity: $12,340 against $1,661 total volume — deep market relative to size

Lines Analysis: The Case for and Against Going the Distance

The YES case rests on Kamaka’s documented tendency to grind fights into the championship rounds. Kamaka has not been stopped by KO/TKO in his UFC career, and his last three UFC appearances included two decisions and a draw. A fighter who almost never gets finished and rarely finishes opponents early is textbook over material at 1.5 rounds, and the market at 56.5 percent reflects that read accurately.

The NO case demands that Luke Riley or Kamaka land a finishing blow inside one and a half rounds. Luke Riley enters UFC 329 as the fighter whose finishing upside drives the NO probability to 43.5 percent. If Riley carries significant knockout power or a submission threat that pressures Kamaka early, the NO outcome becomes live. A first-round finish by either man would immediately resolve this market against the majority position.

• Kamaka decision rate: 71% of UFC wins resolved by judges — strongest factor supporting YES
• Riley finishing potential: Key unknown; any power or grappling edge favors NO
• Round 1 finish risk: Low based on Kamaka’s durability record, but nonzero
• Market depth: $12,340 liquidity supports current price as genuine market consensus
• 24-hour trend: Consistent YES buying over prior day with no reversal signal

The $1,661 in lifetime volume is modest for a UFC prelim prop, but the 56.5 percent YES price has held and extended rather than faded. That directional persistence, combined with Kamaka’s career-long preference for longer fights, gives the over a credible foundation entering fight week.

LINES VERDICT

YES — OVER 1.5 ROUNDS

Kai Kamaka III has spent his UFC career winning and losing on the judges’ cards, and nothing in his recent form suggests that changes against Luke Riley at UFC 329.
