Mintegi Del Olmo vs. Masarova draws $2.1M in 24 hours on Kalshi, with Mintegi Del Olmo at 59%

Tennis contract draws heavy activity

The Mintegi Del Olmo vs. Masarova tennis matchup drew $2.1M in trading on Kalshi over 24 hours, with Mintegi Del Olmo at 59%, according to the supplied headline published Oct 16, 2026, at 3:09 AM ET.

The accompanying summary attributes the activity ranking to DeFi Rate’s most-traded Kalshi list, placing the matchup among the venue’s leading contracts over that period. It does not provide an exact rank or comparable volumes for other contracts.

The supplied source excerpt, however, does not contain the tennis listing. Instead, DeFi Rate’s excerpt identifies SEA Seahawks vs DEN Broncos as having traded on 2 venues in the last 24 hours. It therefore does not independently substantiate the tennis volume or probability reported in the headline.

The summary also says the tennis matchup was absent from any Oct. 16 edition, but cuts off before explaining which editions or why that comparison matters. That limits what can be established about the contract’s broader coverage.

What it means for prediction markets

• The reported 59% places Mintegi Del Olmo on the favored side, but the supplied material contains no price history to establish a trend.
• The $2.1M figure indicates substantial reported turnover, not how many traders participated or how much liquidity remained available.
• The source mismatch leaves the tennis figures supported by the supplied headline and summary rather than the accompanying excerpt.
