What determines a bitrate of stream?

What exactly determines a bitrate of stream? Is it just upload speed of my internet and the quality of my computer that important, or something else? I have around 90 mb/s of upload speed with Ethernet cable, but my bitrate is only around 4500 kbps. How can I increase it to 10000 kbps, for instance? Thank you.

If you are streaming with OBS you have the ability to change your bitrate in settings. Your upload speed just affects the max bitrate you can use.
