15th October 2025 – Tether’s USDT has officially surpassed a market cap of $180B , marking a major milestone in its growth. This achievement reinforces its status as the largest stablecoin and the third-largest cryptocurrency overall, trailing only Bitcoin and Ethereum.
The market cap rise reflects a supply of around 180 billion tokens, each pegged close to $1. Over the past week alone, USDT’s market cap jumped by $3–5 billion, driven by renewed trading activity and on-chain demand.
As of October 15, 2025, USDT holds approximately 61–65% of the total stablecoin market, which currently stands near $290–300 billion.
USDT has shown rapid growth through 2025:

Several factors contributed to this surge:

Tether claims full backing of all circulating USDT. Its most recent disclosures show:
Tether earns an estimated $13B annually from Treasury yields. These profits are reinvested into BTC, gold, and mining.
To increase transparency, Tether now provides daily reports and relies on S&P Global’s on-chain ratings via Chainlink. However, a full third-party audit is still missing.
USDT rise to $180B market cap signals bullish momentum across the crypto market:
Tether also streamlined operations by ending redemptions on legacy chains like Omni and Algorand in September 2025.
Tether is expanding its lobbying efforts in the U.S., supporting legislation like the STABLE Act. Meanwhile, it’s reportedly considering a $15–20 billion capital raise, with potential interest from SoftBank and Ark Invest—though no IPO has been confirmed.
Despite its dominance and USDT hitting $180B market cap, USDT still faces scrutiny:
Overall, USDT’s $180B milestone cements its role as crypto’s digital dollar. But its long-term strength depends on continued transparency, regulatory clarity, and trust from global markets.
