Played until hitting ~47 billion. Some thoughts:
The rival desk raid event, like other events, moves the UI elements when the event appears. More than once, at the end of rapidly clicking, I clicked one more time than I'd needed to, but the end of the event meant that the UI elements move back into place, and I clicked the 2x profits button by mistake. Some mechanism to prevent that kind of accidental mis-click would be nice. Eventually I just started spending my money on more bots instead, so there'd be less money to lose, less clicking, and less risk of mis-clicking.
When not in fullscreen mode, the upgrades eventually flow out of the scrollable area (I was using Firefox 140.12.0esr, did not check in other browsers). When I switched to fullscreen mode, that didn't fix it; without being able to scroll, things just flowed off the monitor. I was running in a virtual machine that only had 1600x900 resolution; maybe that's less than the minimum supported resolution? Otherwise, maybe a way to minimize or hide acquired upgrades would be helpful.
The ability to cancel events and stabilize the market--seemingly for free--makes it feel less like I'm running trading bots in the market, and more like I'm playing in "god mode" . Maybe there's another way to get players to interact with negative events and market conditions, tying in the focus mechanic and different bot types?
