[!info] TL;DR The Coinbase-Circle USDC 50/50 interest-sharing model, originating in the 2018 Centre co-issuance arrangement and continuing after Circle’s 2023 independence, is the stablecoin sector’s largest issuer-distributor incentive-locking structure. Coinbase stablecoin revenue in Q1 2025 was $305M, or approximately 12-15% of total company revenue. Under the GENIUS Act §501 regime, however, the bargaining structure has materially changed, placing the 50/50 arrangement in an unavoidable renegotiation window.

Key facts

• USDC circulation: $40-45B (2024-2025) ^•
• Circle annual interest income: $1.7-1.8B (4.5% Treasury yield) ^•
• Distribution to Coinbase: approximately $905M for full-year 2024 ^•
• Coinbase stablecoin revenue in Q1 2025: $305M, or $1.2B annualized ^•
• Legal basis for the 50/50 split: the 2018 Centre Consortium co-issuance agreement, continuing after the 2023 Centre dissolution ^•

Mechanism / How it works

Historical rationale for the 50/50 split: In the early phase, Coinbase supplied USDC’s principal distribution channel through brand reach, user base, and exchange liquidity, while Circle supplied issuance and reserve management. The 2018 Centre Consortium co-issuance model deeply aligned the two companies. After Centre dissolved in 2023, Circle recovered sole issuance authority, but the 50/50 revenue-sharing provision continued.

Revenue flow: USDC reserves of more than $40B hold short-term Treasuries -> 4.5% annual yield equals $1.8B -> issuance costs are deducted -> net amount of $1.7-1.8B -> Coinbase 50% ($905M) and Circle 50% ($895M).

Bargaining power before and after §501:

Result: The “distributor premium” embedded in the 50/50 model becomes structurally exposed to renegotiation after §501.

Origin & evolution

2018: Centre Consortium established; Coinbase and Circle co-issued USDC, with the 50/50 split as an initial provision. 2020-2023: DeFi summer and the listing boom made USDC the default stablecoin in DeFi; the 50/50 model remained highly symmetrical because distributor value was tangible. 2023.08: Centre dissolved and Circle moved to sole issuance, while the 50/50 provision continued as disclosed in offering materials. 2025.07: GENIUS Act §501 took effect, making compliance standard equipment and diluting the distributor premium. 2025.09: Arc was announced, becoming Circle’s renegotiation lever.
