Makhachev vs Garry UFC 330 odds: is 76.5¢ value?

The single most important input is not the champion’s aura but one measurable rate — how often Makhachev converts a takedown attempt against a fighter who stuffs 80% of them (UFC.com athlete profiles, August 12, 2026). Everything else — the five inches of height, the 16-fight win streak, the trash talk out of Dublin — is downstream of that number. This Deep Dive walks the math, the case for each side, and the three signals that would move the price off its current level.

Methodology: how we built the 74.3%

We did not start from a base rate, because there isn’t one worth using. Makhachev is only the 11th two-division champion in UFC history, and a reference class of roughly 10 fights carries a standard error of about ±13.7 percentage points around a 75% win rate. A sample that small cannot separate a 70% champion from an 80% one, so leaning on it would borrow precision we don’t have — the same problem we ran into pricing our McGregor vs Holloway UFC 329 Deep Dive.

Instead we used a two-state mixture. State W is the fight where Makhachev imposes his wrestling — repeated entries, fence work, meaningful top control. State S is the fight where Garry’s frame and takedown defence hold and it becomes a five-round kickboxing match. Write w for the probability of State W, and the champion’s overall win probability is a straight blend of the two conditional numbers.

Inputs, all career figures from the UFC’s own stats feed as of August 12, 2026: Makhachev’s takedown accuracy of 56% and Garry’s takedown defence of 80%, combined with a log5 odds-ratio adjustment, give a per-attempt conversion of 24.1%. Makhachev lands 3.10 takedowns per 15 minutes at 56% accuracy, so he shoots about 5.5 times per 15 minutes — roughly nine to 11 entries across a 25-minute title fight. Expected takedowns landed: 2.2 to 2.7. Caveats we are explicit about: takedown attempts are correlated rather than independent, Garry’s 80% is drawn from a modest UFC sample, and the two conditional win probabilities are judgement calls that dominate the output.

The market and the price: two venues, one fight

Polymarket’s contract is a straight binary on the winner. At 76.5¢ mid, the cents read directly as a probability, and the book is genuinely liquid for an MMA market: $367,491 of volume on the moneyline with $194,144 of resting liquidity, and $143,771 traded in the 24 hours to our snapshot. The bid-ask is one cent wide. That is a real price, not a stale quote.

Pinnacle is the useful comparison because it is the sharpest posted line in the sport and because its overround is thin enough to strip out honestly. At −352 and +285 the two raw implied probabilities sum to 103.85%. Removing that 3.85% proportionally leaves 75.0% Makhachev, 25.0% Machado Garry. VSiN’s Lou Finocchiaro records the fight opening at −300 and trading at −340 at Circa, so the money since the market went up has come in on the champion.

Is Makhachev at 76.5¢ value? On the numbers, no — and neither is the other side by enough to matter. The Polymarket mid of 76.5¢ is 1.5 points above Pinnacle’s proportionally de-vigged 75.0%, and our own model lands at 74.3%. That makes the champion look about two points rich and the challenger about two points cheap at 23.5¢. But a 2.2pp gap on a fight priced near 3-to-1 is small: it corresponds to shifting one input in our model, the probability that Makhachev can impose his wrestling, by four points. Our honest uncertainty on that input is at least twice as wide. A price is only mispriced if the gap survives your own error bars, and this one does not. The correct read is that two independent venues, a sharp sportsbook and a liquid prediction market, have converged on the same number, and our independent estimate landed on top of them.

“Garry will be the flashy, faster rabbit early in this battle. Makhachev will be the tortoise force pursuing the speedster in meticulous, calculated fashion.”

The case for Makhachev at 76.5¢

The champion’s case is nine months old and 25 minutes long. At UFC 322 on November 15, 2025, Makhachev took the welterweight title from Jack Della Maddalena by unanimous decision, 50-45 on all three cards. He went four-for-four on takedowns, accumulated 19 minutes and 10 seconds of control time in a 25-minute fight, and outlanded the champion 123-32 (CBS Sports). Della Maddalena did not stop a single entry.

Three things in that table carry weight. Makhachev absorbs 1.45 significant strikes per minute against Garry’s 2.86 — the champion is far harder to hit clean, and the challenger has been hittable. Garry’s striking defence of 53% is the softest number on either side of the sheet. And Makhachev’s submission rate of 1.00 attempt per 15 minutes against Garry’s 0.37 means every second spent on the mat is asymmetrically dangerous: Garry has one submission win in 17, while 13 of Makhachev’s 28 wins have come by tap.

“I have the advantage everywhere. I’m going to pressure him, hold him, make him tired and finish him. At UFC 330, I will beat Ian Garry inside three rounds.”

The case for Machado Garry at 23.5¢

Garry’s case is that he is the best takedown-defence test Makhachev has faced at 170lb, and the evidence is not anecdotal. Across his last two fights he has faced 17 takedown attempts from two of the division’s better wrestlers and given up two.

Belal Muhammad is a former welterweight champion whose entire game is chain wrestling, and he went 0-for-7 while getting his lead leg chewed up. That is the performance that earned Garry this title shot, and it is the reason the challenger is 23.5¢ rather than 15¢. Add the physical gap — four inches of reach, five inches of height, six years younger — and a volume differential of nearly two-to-one in significant strikes landed, and State S is a fight Garry probably wins.

“I want four rounds of domination. In that fourth round, I’m going to finish him.”

So is Machado Garry at 23.5¢ the value side? Marginally, on our numbers — and not by enough to call it an edge. Our model gives him 25.7%, which is 2.2 points above the Polymarket price and 0.7 points above Pinnacle’s de-vigged 25.0%. The entire gap comes from one judgement: we put the probability that Makhachev successfully imposes his wrestling at 66%, while Polymarket’s price implies 70% and Pinnacle’s implies 67%. Three or four points of disagreement on a soft input is not a mispricing, it is two analysts reading the same tape slightly differently. The honest framing is that Garry is correctly priced as a live underdog with a clear, repeatable path — keep it standing, win the exchanges, force Makhachev to shoot from range — and that the market has already paid for that path.

Why the de-vig method eats the entire gap

Here is the finding that settles it. The 1.5-point difference between Polymarket’s 76.5¢ and Pinnacle’s “fair” 75.0% is not a real cross-venue disagreement — it is an artefact of how you strip the vig.

Under the power method, Pinnacle’s fair price is 76.46% — indistinguishable from Polymarket’s 76.5¢. In other words, the two venues agree exactly, and the apparent “Polymarket is rich” signal disappears the moment you use a de-vig method that accounts for favourite-longshot bias. Anyone quoting a cross-venue edge on this fight without naming their de-vig method is quoting an artefact. Across every method, the market implies w between 0.67 and 0.70; we sit at 0.66. That is the whole disagreement.

What the prop board says — and why the mids lie

The derivative markets are more interesting than the moneyline, with one large caveat. Polymarket prices “Fight to Go the Distance?” at 55¢, implying a 45% chance of a finish. But the same board prices a knockout or technical knockout at 19¢ and a submission at 34.5¢ — 53.5¢ of finishes in total. That is an 8.5-point internal contradiction on the same event.

It is not a free lunch. The submission market shows a bid of 26¢ against an ask of 43¢, a spread 17 cents wide on roughly $3,000 of liquidity. A mid-price halfway between a bid and an ask that far apart is a number the exchange prints, not a price anyone can transact at. The moneyline, bid 76¢ / ask 77¢ on $194,144 of resting liquidity, is the only market on this fight tight enough to treat as information.

Where the two venues do agree is on length. Pinnacle posts total rounds 4.5 at Over −178 / Under +146, which de-vigs proportionally to 61.2% Over. Polymarket’s O/U 4.5 rounds sits at 60¢ Over. A 1.2-point gap between a sharp book and a prediction market on a secondary line is about as close to consensus as MMA markets get, and it is consistent with the champion’s method profile: 18 of Makhachev’s 28 wins are finishes, but his last title fight went the full 25 minutes and his average fight time of 11:01 is inflated by early-career stoppages.

Where this bet breaks

Our 74.3% rests on assumptions that could fail between now and Saturday night. It breaks if any of these fire:

• Friday’s weigh-in goes badly. This is only Makhachev’s second welterweight camp; he spent his entire championship career at 155lb and moved up in November 2025. A missed weight, a stripped title or a visibly depleted champion on the scale would cut our conditional “Makhachev wins State W” number well below 0.93, and the whole model hangs off it.
• The line moves past −400 or 80¢. At −400 the raw implied probability is 80.0%, and even an aggressive de-vig leaves the champion above 77.5% — beyond the top of our 69.9%–78.7% band. In the other direction, a drift back toward the −300 opening price quoted by VSiN would put the market below our estimate and flip the sign of the gap. The current price is the only reason this reads as efficient.
• Garry stuffs the first two entries clean. The single input we are least confident about is w. Two failed shots inside the opening round, with Garry circling off the fence rather than being walked to it, is direct evidence that w is nearer 0.55 than 0.66 — and the live market will reprice faster than any pre-fight model can.
• A late card change. UFC 330’s bout order has already been shuffled once. Any withdrawal in the main event voids the analysis entirely, and a replacement opponent resets every input in the table above.

What to watch before Saturday

Three dated checkpoints. First, the official weigh-ins on Friday, August 14 in Philadelphia — the number on the scale and how the champion looks getting there is the highest-information event left on the calendar. Second, the closing line: this opened at −300, trades at −340 at Circa and −352 at Pinnacle, and where it settles at the bell tells you whether the late money agreed with the early money. Third, Polymarket’s book depth. With $143,771 traded in the last 24 hours and volume building into fight week, the bid-ask should tighten further; if it widens instead, the mid becomes less reliable, not more.

The card runs at Xfinity Mobile Arena in Philadelphia with prelims from 7:00pm ET and the main card from 9:00pm ET on Paramount+; the Polymarket contract resolves at 03:59 UTC on August 16. Mackenzie Dern versus Gillian Robertson for the women’s strawweight title is the co-main.
