Played it a little bit, it's pretty good, all I'd suggest is giving hints on how to get some of the harder achievements along with maybe some random events like rival companies or having dips in stocks not just when you buy stuff. It's good as a tycoon, but it'll get boring fast without something to engage the player.

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?
