Robinhood's chief financial officer (CFO) Jason Warnick spoke about cryptocurrencies during The Wall Street Journal's virtual CFO Network Summit last week.
There is high demand from retail investors for Robinhood to list more cryptocurrencies, especially shiba inu (SHIB). Warnick emphasized, “We appreciate that our customers want to see us add more coins.” However, Robinhood executives emphasized:

We are a highly regulated company in a highly regulated industry, and it was important for us to get more clarity from regulators.
Compliance is a top priority at Robinhood. In December last year, the company partnered with blockchain data platform Chainalysis to meet compliance requirements.

Supporters of the shiba inu cryptocurrency have petitioned on Change.org for Robinhood to list SHIB. At the time of writing, 555,811 people have signed the petition.
On the other hand, the price of Shiba Inu (SHIB) jumped 16%, due to rumors related to listing on Robinhood.
