Sports betting is back to accounting for more than 70% of all trading volume at the prediction market Kalshi, led by betting on tennis, baseball and hot dog eating.
Eight of the top ten markets for the week ending July 6 were sports markets, and 12 of the top 20. Trading volume is still down from when NBA and NHL betting were available. Here’s a look at the top 20 markets from June 30-July 6.
Some notes on the data:
The top 20 markets accounted for more than 87% of all trading at Kalshi. That means more than a thousand other markets available on the platform accounted for a relatively small portion of all trading.
Betting on Wimbledon was the most popular group of markets at Kalshi for the week, accounting for more than a third of all trading. You could bet on the winner of the tournament (KXWMENSINGLES, KXWWOMENSINGLES) and individual matches (KXATPMATCH, KXWTAMATCH).
The sheer number of matches available early in the tournament helps generate a lot of trading interest.
These markets are also available at Robinhood via Kalshi.
Single-game Major League Baseball betting (KXMLBGAME) was popular as well, accounting for more than 16% of all trading.
The Nathan's Hot Dog Eating Contest was about 10% of all volume across betting on the men’s winner (KXNATHANSHD) and how many hot dogs the winner would eat (KXNATHANDOGS). There were no markets on the women’s contest.
Other sports markets in the top 20 include betting on
The PGA Tour’s John Deere Classic (KXPGATOUR)
FIFA Club World Cup matches (KXCLUBWCGAME)
The Grant Park 165 in NASCAR (KXNASCARRACE)
WNBA games (KXWNBAGAME)
MLS matches (KXMLSGAME)
Interestingly, Kalshi didn’t offer betting on the Gold Cup championship match in soccer between the US and Mexico.
A rundown of other markets appearing in the top 20:

What’s funny is that Kalshi is one of the worst places to bet on sports due to their high hold %. Even compared to FanDuel or DraftKings
