ITF Chacabuco: Giorgia Pedone vs Lucciana Perez Alarcon

Platform comparison

Market context

Giorgia Pedone and Lucciana Perez Alarcon are the live semifinal pairing in the W35 Chacabuco ITF event, and the market is priced far more tightly on trading venues than the headline 100% yes reading suggests. Polymarket shows Pedone around 42¢ and Perez Alarcon around 59¢, while Kalshi is quoting the match as Pedone 31% and Perez Alarcon 69%, so the same contest is being expressed as decimal-style prices on some books and implied probabilities on others.[1][12] That gap matters because a 100% crowd-implied outcome on one venue can still mask active disagreement elsewhere, especially in lower-tier ITF draws where live information can move quickly and liquidity is thinner.[2][6]

Comparable pricing across tennis books points to a contest that has not been treated as a routine favourite-versus-longshot spot. Tennis Explorer’s contemporaneous odds put Perez Alarcon near 1.56 and Pedone near 2.32, while Sportsbet also showed Perez Alarcon shorter at 1.69 against Pedone at 2.01, both broadly consistent with a modest edge rather than a dominant expectation.[5][7] That makes the 100% YES crowd figure look less like a settled view of who wins and more like a market that may already be close to resolution, or vulnerable to a binary settlement rule if the match status changes.

For traders, the main catalysts are straightforward: confirmation that the match was actually played, whether it completed within the seven-day window, and any withdrawal, walkover or cancellation notice from the tournament or scoreboard feeds. Robinhood’s contract rules say a pre-match cancellation resolves to 50-50, and the same outcome applies if the match is delayed beyond seven days without a winner.[1] Kalshi’s live ITF tennis page and Polymarket’s event page also show that this is an actively tracked market, so the key risk is not price discovery alone but whether official start and completion signals arrive cleanly across platforms.[12][16]
