Kalshi has already surpassed $18 billion in monthly trading volume in August, according to data shared by KalshiData, with the month only halfway through when the figure was recorded.

The chart shows just how quickly activity has accelerated this year, rising from under $10 billion in January to more than $40 billion in July.

August still has plenty of runway left, too.

Kalshi is tweaking the economics of its increasingly important combo markets, and retail market makers may want to check the small print.

According to an update highlighted by Quant Chad, Kalshi is introducing maker fees on combo trades, alongside changes to post-only mode and how fees are applied to rapidly executed orders. The poster argues the changes could make retail market making considerably less attractive while boosting Kalshi’s revenue.

With combo trades reportedly accounting for a hefty chunk of platform volume, the change could matter.

Kalshi has spent considerable time, money and legal paperwork arguing that it operates a federally regulated prediction market rather than a sportsbook.

Google, apparently, did not get the memo.

An AI search result shared by Dustin Gouker labels Kalshi a “sports betting company,” while simultaneously describing it as a prediction market platform. The snippet also says sports betting accounts for more than 90% of activity on the platform.

Even though the majority of Kalshi’s battles with gambling regulators is addressing this very issue.

Courts may still be debating the terminology. Google seems to have already placed its bet.

Prediction markets have officially entered their Pokémon era.

Polymarket has launched a market asking whether the price of a Squirtle trading card will rise or fall by August 31, bringing collectible card prices into its ever-expanding betting universe. At the time of the post, traders gave Squirtle a 38% chance of finishing higher, with “Down” trading at 62 cents.

Apparently, catching ’em all is no longer enough.

Prediction markets are getting a rather prestigious invitation: the White House.

Crypto and prediction market executives are expected to gather in Washington on Wednesday, August 19, with President Donald Trump now expected to attend alongside CFTC Chair Michael Selig. The meeting comes just one day before the CFTC’s inaugural Innovation Advisory Committee gathering, putting regulation firmly on the menu.

The original Politico report said the guest list was still being finalized, with traditional finance potentially joining the party too.

Polymarket apparently found out that sometimes the house closes your bank account.

JPMorgan reportedly ended its banking relationship with the prediction market in 2025, telling Polymarket to find another lender amid concerns about its regulatory position. At the time, Polymarket was still subject to restrictions preventing US customers from using its platform following a CFTC settlement.

The revelation comes as prediction markets move increasingly into the financial mainstream, making access to traditional banking rather important.

Kalshi has rolled out its first full geofence in Michigan, but there’s a small catch: users apparently need to install an optional app update for it to work.

InGame reports that a journalist in Michigan could still place sports trades using an Indiana-registered account before updating the app. Once updated, GeoComply kicked in and sports markets were blocked as intended. Kalshi reportedly didn’t alert users that an update was required.

Federal regulators are taking a closer look at prediction markets where traders bet on whether someone will utter a particular word or phrase. The CFTC is reportedly examining “mention markets” over concerns they could be unusually easy to manipulate.

Kalshi has since pulled its sports-related mention markets “until further notice,” although markets involving politicians and corporate earnings remain available. The scrutiny follows controversy surrounding a Trump teleprompter operator who allegedly profited from advance knowledge of speeches.

An Israeli Air Force officer is reportedly facing criminal proceedings after allegedly using classified information to place Polymarket bets linked to military strikes in Iran and Yemen.

According to Israeli media, prosecutors allege the officer used sensitive operational knowledge to gain an edge on prediction markets — which is certainly one way to redefine “insider trading.”

The case adds another uncomfortable regulatory question for Polymarket as authorities worldwide scrutinize who is betting, what they know, and when they know it.

Prediction markets are supposed to reward good forecasting. Having access to classified military intelligence is, apparently, rather too good.

Novig has added Wisconsin to its growing collection of legal opponents, suing state officials in federal court over sports event contracts. The newly CFTC-approved exchange argues its contracts are federally regulated derivatives, meaning Wisconsin shouldn’t get to treat them as ordinary gambling.

Wisconsin may beg to differ. It’s already pursuing Kalshi, Polymarket and Crypto.com over similar offerings, while a federal judge recently declined to stop the state’s enforcement campaign.

Novig, which has also sued New York, Massachusetts, New Mexico and Washington, now wants an injunction.

At this rate, its legal department may need its own prediction market.
