Tether CEO Hails USDT’s Path to 500M Users as Tether Hits $182B Market Cap

Tether CEO Paolo Ardoino declared that USDT’s “trajectory to 500 million users” makes it “the ultimate social network” for programmable money, as the token’s market cap climbs to about $182 billion.

USDT’s 500M-User Trajectory and Today’s $182B Float

On Tuesday, Oct. 21, Tether CEO Paolo Ardoino framed USDT’s scaling in social-network terms, writing: “ USDT’s trajectory to 500 million users in one chart. Programmable money is the ultimate social network. A peer-to-peer construct that transports both information and value.”

Tether’s dollar-pegged token has grown from a 2014 pilot—launched as Realcoin on Bitcoin’s Omni layer and rebranded that year to Tether—to the world’s largest stablecoin by market value. Early issuance was modest, but from 2017 to 2018 supply expanded rapidly as USDT spread across exchanges and later to multiple chains, including Ethereum and Tron.

Chart shared by Tether CEO Paolo Ardoino on Tuesday. By March 2024, circulating USDT passed the 100 billion mark, a milestone that cemented its role as one of the top trading and settlement assets in crypto markets. As of Oct. 21, 2025, USDT’s market capitalization is about $182.1 billion. “Tether USDT reached officially 500 million users,” Ardoino explained a few hours earlier. “Likely the biggest financial inclusion achievement in history.”

Corporate governance and reserves reporting evolved alongside that growth. Following several regulatory actions in 2021, Tether began releasing quarterly reserve attestations by BDO Italia and has shifted its portfolio heavily toward U.S. Treasuries and other cash-equivalent assets.

The company reported $4.9 billion in net profit for Q2 2025 and about $127 billion in Treasuries at mid-year, according to its July attestation update. Leadership also changed: Paolo Ardoino, previously CTO, was appointed CEO in late 2023 and took the helm that December.

Onchain distribution has continued to shuffle. After years of Tron dominance in low-fee retail transfers, Ethereum reclaimed the top spot for USDT supply during 2025 amid lower fees and deeper liquidity, with analyses in late Q3 highlighting the shift. Today, just over 100 billion USDT is issued on Ethereum, while Tron’s issuance stands at 78 billion tethers.

In parallel, the broader stablecoin sector expanded, with USDT remaining the leading dollar-linked token as the market crossed the $300 billion range in 2025, even as new products and networks emerged. Other top competitors nipping at Tether’s heels include Circle’s USDC, Ethena’s USDe, Sky’s DAI and USDS, and Paypal’s PYUSD.

Ardoino’s “programmable money” framing arrives as Tether positions USDT across multiple blockchain rails and emphasizes attestations; the company’s scale and reserves mix will remain central metrics as stablecoins see wider payment and settlement use. While Tether may wear the crown today, the throne isn’t nailed down—especially with fiat-backed coins like USDC, USDe, and PYUSD multiplying faster than a magician’s deck shuffle.
