Visa and MasterCard stocks rose on Friday after The Wall Street Journal reported that Walmart and Amazon, among other retailers, are considering issuing their own stablecoins for customers, a move that could siphon revenue from traditional payment service providers. The newspaper noted that decisions to issue stablecoins (cryptocurrencies tied to stable assets like the U.S. dollar) hinge on the approval of the Genius Act, which was issued by Congress, and which should be regulated and requires the holding of reserves in dollars or other assets.
