XLM may have inroads at having Fidelity move onto their blockchain because of inside connections between the two. Fidelity’s head of corporate business development is the former head of Chain, which stellar bought and merged with lightyear to form interstellar. That means that he is familiar with Stellar’s ecosystem and has connections with people high up on the Stellar ladder. Chain and Lightyear already have a number of financial institutions, including VISA, on their network and integrating Fidelity would be a big boost to business and blockchain activity. Since partnerships at the high levels are generally driven by networking and familiarity, Stellar has a good chance of landing Fidelity if it decides to come to the blockchain world.
