Market context

Jesus Aguilar and Rei Tsuruya are scheduled to meet on the UFC’s Macau card in the flyweight prelims next Saturday, and the market is sitting near a 50/50 split because neither side brings a clear, dominant pricing edge. Aguilar is the more established name, with a longer UFC run and a 12-4 record listed by ESPN, while Tsuruya is the younger, narrower favourite profile at 10-1. Recent market notes have already pointed to Aguilar’s higher-volume striking and Tsuruya’s willingness to wrestle, which is the sort of stylistic contrast that can keep a flyweight line close right up to weigh-ins.

For context, evenly priced UFC flyweight prelims often move on late information rather than reputation alone. A fighter with the cleaner grappling path can gain ground if the opponent has difficulty defending takedowns or making 125 cleanly, but the reverse is also true if the bout is likely to be kept standing over three rounds. Aguilar’s profile suggests experience and pace; Tsuruya’s record suggests a stronger recent form line. That balance is consistent with a market that is not yet convinced by either side.

The main catalysts now are official fight-week confirmations: weigh-ins, any card reshuffles, and whether the bout remains firmly on the prelims slot in Macau. Sofascore lists the fight for 30 May at 07:00 UTC, and ESPN has Aguilar’s next fight locked in against Tsuruya, so the key question is not whether the match-up exists but whether any late camp or medical issue changes the shape of the market. If there is no change through weigh-ins, the current probability is likely to remain tightly bunched rather than drifting sharply.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
