Madrid isn’t a clay court …at least not in the way it counts. High altitude and hot, dry conditions lead to faster ball speeds, shorter rallies and higher hold rates.

Hold % at the Madrid Open is 4% higher than typical clay courts

The problem…

Other tennis suppliers calibrate via generic court types (hard, grass, clay), this overlooks key performance drivers essential when pricing extended markets.

If the core assumptions are wrong:

  • Match odds drift
  • Game lines misalign
  • Derivatives get exposed



Further down the market chain, each pricing error is amplified, generating unwanted exposure and avoidable liability


10star’s Edge

  • We trade core markets in the toughest environments, to the tightest margins and in the largest sizes
  • Decades of exchange trading data give us a precise read on how every court plays. Built on history, not assumptions
  • By modelling altitude, weather, and court construction in real time, we stay margin-leading even across the most obscure markets
  • Every market is connected. Risk cascades from match to sets, games and points – and correlates back. We price the full tree, not in isolation
