Kalshi’s esports markets traded $231.8 million throughout 4.05 million particular person trades in June 2026, unfold throughout 28 distinct sequence masking seven titles.

CS2 completely dominates June
There’s a transparent market chief in what individuals are buying and selling in June, and the reply’s clearly Counter-Strike. 59% of each esports contract traded on Kalshi in June 2026 was on Counter-Strike 2. This was virtually fully single-match betting (made up of recreation winner, map winner and total-maps markets), plus a small slice on the tournament-outright market.
No different title cracked 12% of the month’s quantity, and the sheer dominance was notably pronounced at IEM Cologne within the third week.

League of Legends Sport Winner was a distant second at 11.6% of the month ($26.8 million), with Valorant’s game-winner market shut behind at 8.7% ($20.1 million). Between them, CS2’s single-match betting, LoL’s recreation market and Valorant’s recreation market accounted for 77% of all the things traded on Kalshi’s esports board in June. It goes to point out that when there’s a significant Counter-Strike occasion on, it swallows the competitors. Whether or not or not that modifications in July with LoL’s MSI going down stays to be seen.
Share of Month-to-month Contract Quantity, by Sport
What “57%” is definitely manufactured from
It’s value breaking such a considerable quantity down. CS2, broadly talking, isn’t only one market on Kalshi. It may be break up into 5. These are whether or not a staff wins the match; whether or not it wins a given map; whether or not the match goes over or underneath a total-maps line; whether or not a staff qualifies for the following stage of a match; and, individually, who wins the entire occasion outright. Practically four-fifths of CS2’s complete month-to-month quantity, $103.8 million, sat within the single “who wins the match” market alone. Map winner markets added one other 20% ($26.9 million).

The IEM Cologne impact, at a extra granular degree
The match comfortably produced just about the entire high ten greatest markets, and stealing a desk I made for the IEM Cologne evaluation, the match-level wagering usually adopted the match development.
Falcons had been concerned within the high three traded markets. This may merely be defined by the magnitude of the eventual winners’ contests with the 2 groups tipped to win all of it pre-tournament in Workforce Spirit and Workforce Vitality.

League of Legends might be set for a giant MSI
One match would break into the highest ten, sitting simply above 9z vs FURIA outdoors of Counter-Strike and that match was T1 vs Gen.G which noticed $1.97 million traded. There’s not been an terrible lot of League of Legends motion of late with MSI play-ins simply ending up (and my god, did T1 look robust). The Korean World Champions didn’t drop a single map as they swept their method to the principle stage at MSI. As we transfer into July, it’ll be fascinating to see if having an enormous international League of Legends occasion takes a few of Counter-Strike’s thunder. On condition that the variety of fixtures is considerably decrease, MSI might not attain Cologne’s complete seismic quantity,however I’d count on there to be some heavy-hitters on match quantity alone.
