What is the total stablecoin market cap?

I don't have a direct tool that returns the live aggregate stablecoin market cap, so I can't give you a verified current number — but I can give you the general picture.

As background knowledge (not a live data point): the total stablecoin market cap has been around the $200–230 billion range in recent months, with the market split roughly as:

• Tether (USDT) — the dominant leader, consistently ~$140+ billion, roughly 2/3 of the entire stablecoin market
• USD Coin (USDC) — the clear #2, around $40–60 billion depending on the period
• DAI / USDS, FDUSD, USDe (Ethena), PYUSD, TUSD — smaller but notable shares
• The balance spread across dozens of smaller regional and niche stables

Two structural things worth knowing:

1. Fiat-backed stables (USDT, USDC, PYUSD) dominate — the biggest risk dynamic is the reserve transparency of the issuers, which is why USDT vs. USDC debates keep recurring.
2. The number moves meaningfully with market conditions — stablecoin supply tends to expand during bull runs (more fiat flowing into crypto) and contract in risk-off periods as people redeem back to fiat. It's often watched as a proxy for "dry powder" waiting to be deployed.

This is general context rather than a live figure. If you want, I can pull current market data on the specific stablecoins — say, a comparison of USDT vs. USDC vs. USDe (price, market cap, 24h change) right now, which would ground the picture in real numbers. Want me to do that?
