Kalshi v9.9.113 removes parlay sharing and BTC chart data in August 2026 update, causing rating drop

Official release notes for version 9.9.113 stated only 'bug fixes and performance upgrades', providing no information on the significant user-facing changes.^[2] This lack of transparency contrasts with the scale of the update, which altered core trading functions and the primary user interface.

The changes coincide with Kalshi's strategic pushGlossaryPush NotificationA message delivered to a user's device from your app's server — the single biggest re-engagement lever in mobile, when done well, and a fast path to uninstall when d... towards more sophisticated traders, marked by the July 2026 launch of 'Kalshi Pro,' a professional-grade desktop trading terminal. This suggests the mobile update may have been an attempt to unify the user experience across platforms, albeit one that was poorly communicated to its existing mobile user base.

The update introduced several breaking changes that directly affected usability. Users reported the removal of the ability to share parlays, which Kalshi calls 'Combos'. Additionally, traders of high-frequency Bitcoin markets lost a critical tool when the seconds display was removed from the BTC chart. A third major issue was a new, confusing interface.

These removals disrupted established user workflows. One 3-star reviewer on v9.9.113 stated, "You removed the seconds from the BTC up and down chart, you only show the minutes now, and you made the chart smaller. Screwed up my strategies." Another 2-star review confirmed, "The most recent update prevents users from sharing any parlays."

Before the v9.9.113 update, sentiment was generally positive, with users praising the platform's odds and ease of use. A 5-star review on the prior version noted, "Quick and easy to use. Deposits and withdrawals are simple which is a huge plus." After the update, the tone shifted dramatically.

Negative reviews focused on the new interface. One 1-star review on v9.9.113 described the experience: "The constantly switch from the old interface to the new interface which makes it difficult to navigate and track your bets on the new interface. Please stick to the old interface Kalshi."

The v9.9.113 update appears to be a misstep in Kalshi's attempt to cater to professional traders without alienating its broader mobile audience. With over 622,000 downloads in the last month, the app's user base is substantial, and the sharp rating drop poses a risk to future user acquisition.

The publisher's next update will be telling. A failure to address the specific complaints about the interface and removed features may signal a deliberate pivot away from the casual user experience that built its audience. It remains to be seen if Kalshi will revert the changes, offer a choice of interfaces, or double down on its new 'Pro' focused direction.
