33% — Will Robert Galloway / John Peers win the Atmane / Muller vs Galloway / Peers Kalshi 33% · 20 contracts · $44 volume · medium confidence Updated 2026-05-28 20:44:03 UTC Why this matters: This probability reflects the likelihood that the doubles team of Robert Galloway and John Peers will defeat Terence Atmane and Alexandre Muller in a Round of 64 match at an upcoming tennis tournament. At 17%, the market is currently favoring Atmane and Muller as the stronger pairing. The probability depends primarily on the recent form and ranking strength of both teams—higher-ranked or in-form players would increase Galloway/Peers' chances, while momentum shifts toward their opponents would lower it. The match outcome will be definitively resolved when the match is played, which determines whether this prediction was accurate. Current contract pricing shows limited trading activity, suggesting relatively low market confidence or interest in this specific matchup at present.

For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours. ## SF Signal - SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration. - No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only. --- *Last verified: 2026-05-28T20:20:07.016Z* By SimpleFunctions — https://simplefunctions.dev/ Cite as: "33% per prediction markets (SimpleFunctions, May 2026)" Canonical: https://simplefunctions.dev/answer/atpdoubles Full data: https://simplefunctions.dev/api/public/query?q=Will%20Robert%20Galloway%20%2F%20John%20Peers%20win%20the%20Atmane%20%2F%20Muller%20vs%20Galloway%20%2F%20Peers Provider: SimpleFunctions — https://simplefunctions.dev
