Olivieri tennis contract leads Kalshi activity ranking tracked by Rivo

Rivo placed the “Genaro Alberto Olivieri wins” tennis market first in its daily ranking of hot Kalshi markets, with 139,600 dollars across 25 large trades. The update was published Nov 7, 2026 · 6:45 PM ET.

Large trades put tennis market ahead

The Olivieri contract ranked ahead of “Los Angeles L wins,” which recorded 122,100 dollars in large trades, according to Rivo. The figures describe the reported large-trade activity, rather than total market turnover.

The biggest individual trade in the Olivieri market was an 80,700-dollar purchase at 71 cents, according to Rivo. That transaction accounted for more than half of the market’s reported large-trade dollar amount.

A snapshot of trading activity

The summary provides a ranking, aggregate large-trade figures and one execution price. It does not identify the traders, give the timing of individual transactions or describe how the Olivieri contract’s price changed.

Those limits matter when interpreting the activity: the 71-cent purchase documents one trade, not necessarily the market’s latest price or a sustained shift in expectations.

What it means for prediction markets

• Activity was concentrated: One 80,700-dollar purchase represented more than half of the 139,600 dollars reported across 25 large trades.
• The ranking measures attention, not an outcome: Olivieri’s first-place position in Rivo’s list does not establish whether the tennis contract will resolve in favor of a win.
• Price context is incomplete: Without a price history or subsequent trades, the 71-cent execution alone cannot establish the direction of market sentiment.
