I previously got a job at UpWork, from finlete.com. (a website where fans invest in their athletes and in return will get a share percentage of the athlete's future earnings.) I rejected the offer because I thought that's not halal.
Can you guide me?

However, if you conduct an immediate transaction among yourselves, then there is no need for you to record it, but call upon witnesses when a deal is finalized. Let no harm come to the scribe or witnesses. If you do, then you have gravely exceeded ˹your limits˺. Be mindful of Allah, for Allah ˹is the One Who˺ teaches you. And Allah has ˹perfect˺ knowledge of all things. (2:282)
Whatever loans you give, ˹only˺ seeking interest at the expense of people’s wealth will not increase with Allah. But whatever charity you give, ˹only˺ seeking the pleasure of Allah—it is they whose reward will be multiplied. (30:39)
Here we are told what interest is halal. If we aren't exclusionary and immediate, we help with investment. I say an investment is consumption until it is proven to deflate.
Like any library, Islam Stack Exchange offers great information, but does not offer personalized advice or legal verdicts, and does not take the place of seeking such advice from your Mufti, Imam, or other trustworthy Counselor.
