USDC sits where regulation pays and yield does not.
The dollar-stablecoin map has six credible inhabitants. Two axes determine where each one wins: regulatory posture and ability to pay yield.
Regulatory posture × yield-payment ability
Solid stroke = stablecoin (regulated as payment instrument, no yield to holder). Dashed stroke = tokenised MMF or bank deposit token (can pay yield, classed differently). Bubble area scales with float / AUM.
Where Circle actually wins — intangibles + regulation
The single most defensible asset
"Being the compliant choice when regulators or fiduciaries enforce a choice." MiCA delisted USDT; bank treasurers can't hold an asset audited only by point-in-time attestations from BDO Italy with 13% non-cash reserves; the GENIUS Act's reserve-quality and audit requirements re-rate Circle's preexisting compliance posture as table stakes — Circle was already there, competitors had to build to it.

- a. The Coinbase deal extracts >50% of revenue and Coinbase's veto rights limit strategic optionality.
- b. The regulatory premium narrows every quarter as USAT, JPMD, WFUSD, and the bank consortium close the compliance gap.
- c. Tokenised MMFs offer yield Circle legally cannot — structural problem for institutional treasury.
USDC vs USDT — mass vs use
USDT wins mass — it's the parking-lot stablecoin in offshore EM and perp collateral pools. USDC wins use: 64% of adjusted on-chain transaction volume, the metric that actually predicts payment-rail share. That's what Visa, Mastercard, Stripe and Meta partnerships pay for.
