SoFi is offering 5,000 points ($50) when you enroll in SoFi Plus and keep it for 90 days. Rakuten is offering $25/2,500 when you click through and sign up for SoFi Plus. SoFi Plus is free with a direct deposit of any amount, or you can pay $10/month. When clicking through the Rakuten link it directs me to the page showing the $50 bonus, so these two offers would appear to stack.
