Motley Fool posted a comparison between Rigetti Computing and IBM for quantum computing exposure. They think Rigetti (RGTI) is too risky right now despite the stock being up over the last five years. The company only had $7.5M in revenue over the last year but lost $351M. They also have a high burn rate and keep diluting shares. They recommend IBM as a safer alternative. IBM isn't a pure play but has over 200 quantum clients like Boeing and Wells Fargo. They are also profitable with net income growth and pay a 2.3% dividend. Basically, RGTI is seen as overvalued at a $7.2B market cap given the low revenue and high error rates in their current tech.
