ITF Men's Tennis 2026 — the futures tier

Two of today's ITF men's boards are quoting 50 cents a side while their last prints sit at 99 and 1. Cocola–Wessels has turned $1,120,658—the largest tennis contract anywhere today—with $569,747 on Wessels and $550,911 on Cocola, and a midpoint of exactly 50% on both. Rehberg–Catini does the same on $124,467. That is what an in-play match looks like when the maker widens to a full-width two-way and the last trade stops being a price.

On the settled-looking boards the cheap side keeps taking about 40% of the money. Toby Martin at 0.5% has taken $49,947 of Garcian–Martin's $122,274. On the women's circuit the same shape: Alexa Karatancheva at 0.5% took $41,269 of $103,951. Neither of those is a hedge—open interest on both cheap legs runs to tens of thousands of contracts.

And one board is genuinely balanced. Vanshelboim–Seghetti is 96.5 / 3.5 and the two sides have taken $13,641 and $13,508—within one percent of each other on a twenty-eight-to-one price.

This page now carries the men's ITF circuit only. ATP Challenger books sit on the Challenger page and the women's ITF boards on the women's page; the three were splitting the same handful of matches between them.

The ITF men's futures tier is the busiest tennis market on Kalshi by volume and the thinnest by field quality. Left: Garcian–Martin, 99.5 / 0.5 on $122,274. Right: Dummer Macedo–Cunha, $17,292, one of the last men's boards to settle today at 18:00 UTC.

Left: Axel Garcian at 99.5%, which took $72,327. Right: Toby Martin at 0.5%, which took $49,947—41% of the board on a leg priced at one in two hundred, carrying 28,468 contracts of open interest.

That ratio has held on ITF boards every day this page has been anchored on them.

The 50/50 midpoint is the thing to understand on this page. When an ITF match goes in play, Kalshi's maker pulls to a one-cent bid and a ninety-nine-cent offer, and the API reports the midpoint as 50%. It is not a market that thinks the match is a coin flip; it is a market that has stopped quoting. Read the last print and the volume split instead.

The cheap-leg bias is the other constant. Across today's four decided boards, legs priced at 0.5% to 4.5% took between 11% and 41% of their board's volume. The catalog now sees this pattern on Fed boards, NFL props, Netflix charts and temperature ladders; ITF tennis produces it at the highest ratio of any of them.

Watch the overnight roll. These books open a few hours before play and settle within the day, so the whole page turns over daily. What does not turn over is the shape: favourite at 95 to 99, a cheap leg taking a third of the money, and open interest that says the cheap side is held rather than scalped.

Mazzola–Weis, $31,967: Mazzola at 9.5% took $18,410 against Weis at 91.5% on $13,557—the underdog outtrading the favourite by a third. Nagoudi–Chauhan, $15,961: Chauhan at 88.5% took $12,685 to Nagoudi's $3,276, the one board today where the money follows the price.

Below: Souza–Pereira Xavier, 95.5 / 4.5 on $14,822, the last men's ITF board to settle today at 18:00 UTC—and the 2027 Australian Open women's board as the control, four months out and barely quoted.
