Ethereum dominates USDC issuance with 70% of $72B market cap
If you want to understand where the stablecoin economy actually lives, look at Ethereum. Circle’s USDC has grown into a $72 billion asset, and roughly 70% of that supply, around $49.5 billion, is issued natively on Ethereum.
The numbers behind the dominance
Ethereum’s share of USDC issuance sits at approximately 68.8% of total supply. Solana, which is widely considered Ethereum’s most credible competitor for stablecoin activity, hosts around $7 billion in USDC. That is roughly one-seventh of what Ethereum handles.
USDC itself has grown considerably over the past year or so. The total supply has climbed from around $60 billion in early 2025 to over $72 billion today, driven by institutional adoption and the continued expansion of DeFi protocols that rely on dollar-denominated liquidity.
Circle first launched USDC on Ethereum in September 2018. The acceleration of multi-chain expansion came with the rollout of the Cross-Chain Transfer Protocol, or CCTP, starting in 2023.
What CCTP actually changes
Before CCTP, moving USDC between blockchains meant using a bridge, which meant holding a wrapped or “bridged” version of the token, often called USDC.e on chains like Avalanche. Bridged tokens carry smart contract risk, are not directly redeemable with Circle, and create a fragmented liquidity picture.
CCTP burns the tokens on the source chain and mints fresh, native USDC on the destination chain. The user ends up with a token that is directly backed by Circle’s reserves, not a derivative of one.
Circle has now extended native USDC and CCTP support to 35 blockchains. Recent additions in 2026 include Cronos, Injective, Stellar, and World Chain.
Stellar’s inclusion is worth noting specifically. Stellar has historically been oriented toward cross-border payments and remittances rather than DeFi. Native USDC on Stellar signals that Circle is pursuing the broader payments infrastructure market, not just DeFi activity.
Why Ethereum’s lead is stickier than it looks
Ethereum’s DeFi ecosystem has years of accumulated liquidity in lending protocols, decentralized exchanges, and yield strategies, all denominated in USDC. Moving a large institutional position through a thin liquidity environment creates slippage. Moving it through Ethereum’s ecosystem, at scale, does not.
For investors and traders watching stablecoin market structure, the $72 billion USDC supply figure is less interesting than where it sits. Ethereum’s $49.5 billion slice of that pie is the foundation for the lending rates, swap depths, and yield opportunities that define DeFi economics.
As native USDC reaches more chains through CCTP, the use case for Tether’s USDT, which still leads overall stablecoin supply, becomes more contestable on newer networks. Chains that once defaulted to USDT because native USDC was unavailable now have a choice.

Bernstein believes that the co-packaged optics (CPO) and fiber demand driven by Nvidia's Rubin Ultra architecture will surge significantly, with the optical content per Pod rising from $1 million to $5.4 million. This will propel the size of Nvidia's optical ecosystem market to $46.8 billion by 2028 (a 91% annual increase). Although the industry faces supply bottlenecks with InP substrates, the outlook remains positive. The institution reiterates its “outperform” rating for Lumentum, Coherent, and Ciena.

$3.7 billion “data center power equipment prepayments” abandoned! What did "the most active buyer of gas turbines", SoftBank, see?
In the second quarter of fiscal year 2026, SoftBank reported a net loss of $7.1 billion, primarily due to a $3.7 billion impairment charge from a $9.5 billion advance payment for power generation equipment for US data centers—of which about $2.9 billion was non-refundable and effectively lost. The CFO admitted that SoftBank placed orders before the project plan was finalized, and is now conducting a comprehensive review of its procurement strategy. "The most aggressive purchaser of gas turbines has now written off the deposit in this way."
