Plovdiv: Tommaso Compagnucci vs Maxim Mrva

Platform comparison

Active sub-markets

Market context

Tommaso Compagnucci and Maxim Mrva are already into the scoreline, and the market should now be read as a near-binary “who advances?” contract rather than a price on pre-match form. The crowd-implied **100% YES** is much firmer than the pre-match sportsbook view, where FanDuel listed Mrva around **1.333 decimal** against Compagnucci at **2.96**, implying a much less lopsided contest than the current market price suggests.[1][3] That gap is consistent with prediction markets moving to certainty once live completion risk falls away; on Polymarket, the contract pays in a yes/no structure, while Kalshi-style or exchange pricing is often easier to compare to a direct implied probability than to decimal odds, and Betfair/Smarkets users would also need to factor in commission and local KYC access before comparing the same match.[3]

The historical frame is thin because this is the pair’s first recorded meeting, so there is no head-to-head sample to anchor a fair line.[1] Tennis preview sites nonetheless leaned Mrva before play, while live scoreboards show the match underway in Plovdiv, which is the key distinction for settlement: if one player completes the match and advances, the market resolves to that player; if play is abandoned, cancelled, or left unresolved beyond the market window, the contract can still fall back to 50-50 under the rules.[2][4][6] That means the main catalyst is not form news but operational news — completion, retirement, suspension, or a confirmed winner from the ATP event feed.[4][6]

Methodology

We read Plovdiv: Tommaso Compagnucci vs Maxim Mrva from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Kalshi Alternative UK routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
