Stablecoin market just hit a major milestone. Last year, transaction volume jumped 72% year-over-year, reaching a record $33 trillion. That's massive. What's really interesting though? USDC flipped the script. With $18.3 trillion in transactions, it's now the king of transaction flow—beating USDT's $13.3 trillion. For years USDT dominated, but the landscape is clearly shifting. USDC's growth shows users are voting with their wallets, attracted by its issuer's regulatory posture and perceived stability. USDT still holds significant market share, no question about it. Yet the competition is intensifying, and this data suggests the stablecoin hierarchy we thought was locked in place might be getting rewritten. What does this mean for traders and institutions? More optionality, different risk profiles to evaluate. The market's sending a signal—diversification in stablecoins isn't just possible anymore, it's becoming the norm.
