Wall Street is doubling down on crypto as major financial institutions accelerate their blockchain strategies. Mastercard is enabling 3.5 billion cardholders to make Bitcoin and crypto transactions, Western Union has launched its USDpt stablecoin on Solana, and the NYSE-backed ICE is partnering with Polymarket to adopt 24/7 tokenized collateral. Meanwhile, new ETF filings and growing institutional investment signal that traditional finance is moving deeper into digital assets. As adoption expands, the line between crypto and Wall Street continues to blur.
