An analysis of Polymarket trading over the past year found an average of over $1 million was traded on LoL matches, with the highest match recording $28.3 million. In comparison, NFL, NBA, and NHL matches all traded more, but the gap is not as large as it used to be.
NFL matches led the way with an average of $5.2 million, followed by NBA at $4.2 million, and NHL at just over $3 million, according to analysis by Doc’s Sports .

Trading on sports is increasingly seen as a financial investment strategy by Gen Z, with the rise of prediction markets making that option available nationwide.
Overall, esports trading volume is growing considerably. At Kalshi, users traded over $344 million on events in the last 30 days, up from $113 million in April.

VALORANT is also seeing a rise. Back in June, it averaged less than $1 million per day, but now easily surpasses $2 million on a daily basis.
At Polymarket, the story is similar, although trading on Dota 2 is higher than VALORANT. Outside of those four games, there was relatively little trading. The figures below are for 365 days, ending July 30th, 2026.

Those trading volumes do not include users placing parlays, which have become increasingly popular at Kalshi.
Parlays now exceed individual sports market trading on the platform, with $14.4 billion in volume over the past month. Individual markets saw $13.5 billion in trading.
It is important to note that parlays will always show inflated volume figures due to their longer odds. For example, is a user places a single bet of $2 that could return $4 then that would show as $4 in volume. If the user combines selections to place their $2 on a parlay that has…
