Circle’s USDC notched a 2.40% weekly climb to reach $79.247 billion, putting it within striking distance of the $80 billion milestone. Moreover, just recently, Mizuho Securities analysts Dan Dolev and Alexander Jenkins revealed that adjusted stablecoin volume shows USDC outpacing USDT in 2026.

Paypal’s PYUSD took a 1.78% tumble to $4.106 billion, while Blackrock’s BUIDL edged down 0.14% to $2.2 billion. Then there’s Circle’s USYC, which seemingly chugged an entire tray of energy drinks and proceeded to post a punchy 13.9% gain over the past week, lifting its market cap to $2.264 billion.
Finally, global dollar (USDG) closes out the top ten, strolling in with a 4.15% gain and a $1.663 billion market cap. While Tether accounts for 58.24% of the sector on its own, the combined value of the top ten stablecoins represents 93.97% of the market’s $315.944 billion total, or roughly $296.914 billion. This means that out of the 351 stablecoins logged by defillama.com, a hefty 301 of them collectively account for just a hair over $19 billion in value.
Crossing the $315 billion mark this week, the stablecoin sector continues to quietly step into a new tier of financial heft. The milestone highlights how deeply dollar-pegged tokens have embedded themselves in crypto trading, payments, and decentralized finance ( DeFi). If current issuance and adoption trends hold, 2026 could bring another wave of expansion as institutions, fintech firms, and blockchain platforms continue piling into the stable-value game.
