Stablecoin Market Hits $301B as Q3 Reshuffles Capital Across Chains

• Stablecoin supply reached $300.9 billion across 195 assets.
• Tron gained $5 billion while Ethereum lost $4.9 billion in supply.
• Circle led issuer growth with $915 million added during Q3.
• BNB Chain dominated distribution with 12.9 million new holder addresses.

Stablecoins crossed $300 billion in market capitalization during the third quarter, but the new capital did not follow the networks and issuers with the fastest growth in wallet distribution.

The market stood at $300.9 billion on Oct. 1, spanning 195 assets, 152 issuers and 47 blockchains, according to the Q3 2026 edition of RWA Activity on the Terminal, produced by RWA Foundation and Token Terminal.

Addresses holding a non-zero stablecoin balance reached 308.4 million.

The quarter produced a clear split between where stablecoin capital accumulated and where stablecoins reached new wallets.

Tron captured the largest increase in supply. Circle led issuer growth. BNB Chain dominated new holder addresses. Tether, meanwhile, lost a small amount of outstanding supply while continuing to add wallets at a scale newer stablecoins have yet to approach.

That separation provides a more useful view of the $301 billion market than market capitalization alone.

$10B Swing Separates Ethereum and Tron

The most consequential change occurred at the blockchain level.

Tron’s stablecoin supply increased by $5 billion over 90 days, or 5.6%, taking the network to $93.9 billion.

Ethereum recorded a $4.9 billion decline over the same period.

The opposing moves created a nearly $10 billion swing in their relative positions during a single quarter.

Ethereum nevertheless remains comfortably ahead, hosting 54.2% of global stablecoin supply compared with Tron’s 31.2%. Together, the two networks account for more than 85% of the market.

Further down the rankings, growth was distributed across a much newer group of chains.

HyperEVM added $1.5 billion, a 28.3% increase that lifted its stablecoin market to $7 billion. Robinhood Chain gained $649.2 million and Arc added $464.9 million, followed by Arbitrum One with $277.5 million.

Stellar, Sonic, Monad, OP Mainnet and Base completed the ten fastest-growing networks.

Collectively, those ten chains added approximately $8.4 billion. Tron alone generated about 60% of that increase.

The Q3 numbers therefore show two trends developing simultaneously: most stablecoin capital remains concentrated on Ethereum and Tron, while meaningful new supply is beginning to appear across a broader set of networks.

Circle Leads Growth as Smaller Stablecoins Gain Ground

Issuer concentration changed far less than chain distribution.

Circle added $915 million over the quarter, the largest increase among stablecoin issuers. Ripple followed with $765.3 million, while United Stables gained $474.2 million.

At the asset level, USDC added $881 million, followed by RLUSD at $765.3 million and U at $474.2 million.

USDe expanded by $419.1 million, while USDGO gained another $315.6 million.

The composition of that growth is notable because several of the fastest-expanding assets remain tiny relative to the market leaders.

RLUSD represents only 0.8% of stablecoin supply, while U accounts for 0.5%. Neither needs to attract anything close to USDT-scale capital for its market share to change materially.

USDT sits at the opposite extreme. Tether’s market capitalization declined by $207.7 million during the quarter, leaving it outside the ten largest growers.

That barely altered the industry’s concentration.

Tether still controls 61.1% of outstanding stablecoin supply, while Circle holds 24.8%. Their combined 85.9% share is almost identical to the 85.8% recorded in the previous monthly report.

Q3 therefore brought faster growth among challengers without materially weakening the two largest issuers’ control of outstanding supply.

Tether’s Quarter Looks Completely Different by Holder Growth

Supply rankings capture only one side of the market.

Tether added 17.2 million holder addresses during the same 90-day period in which its market capitalization contracted.

Circle gained another 8.1 million addresses. Combined, the two issuers accounted for roughly 95% of the 26.6 million addresses added by the quarter’s ten fastest-growing issuers.

Ripple presents the inverse case.

Its $765.3 million increase placed it second for new issuer supply, yet it added only 23,600 holder addresses, ranking tenth on that measure.

The difference is substantial enough to separate two forms of expansion.

Supply growth measures how much additional stablecoin value is outstanding. Holder growth measures how many additional blockchain addresses carry a non-zero balance. An issuer can perform strongly on one without doing so on the other.

Holder counts also require an important qualification: addresses are not users. One person can control several addresses, and custodial infrastructure can aggregate balances belonging to many customers.

Even with that limitation, the data show how differently new stablecoins are scaling. RLUSD accumulated capital rapidly in Q3, while the established USDT and USDC networks continued adding addresses by the millions.

BNB Chain Dominates the Distribution Side

The contrast becomes even sharper when stablecoins are grouped by blockchain.

BNB Chain added 12.9 million holder addresses during Q3, nearly five times the 2.6 million added by second-place Celo.

Tron gained 2.2 million, Solana 2 million and Ethereum 1.7 million. Arbitrum One and Base followed with 1.6 million and 1.5 million respectively.

Across the ten fastest-growing chains, approximately 26.3 million addresses were added. BNB Chain contributed almost half.

Yet its share of outstanding stablecoin capital remains small.

Stablecoin Supply and Holder Distribution

This is one of the clearest signals in the Q3 dataset.

Ethereum has more than half of stablecoin supply but less than one-tenth of holder addresses. BNB Chain has the largest holder share despite accounting for barely more than 1% of supply. Polygon displays a similar, though smaller, imbalance.

Tron is the exception among the four. Its 31.2% share of supply sits much closer to its 25.2% share of holders.

The figures do not establish who controls those wallets or what each balance is used for. They do show that capital concentration and address distribution vary dramatically between chains, making either metric incomplete when viewed alone.

$100B in Q3 Transfers Adds Another Layer

Holder and supply figures still do not capture how frequently stablecoins actually move.

Tokenized-stock and stablecoin markets are increasingly being evaluated through activity measures alongside outstanding value, and the same distinction is useful here: an address can hold a balance without using it frequently, while large amounts of capital can circulate through a relatively small number of wallets.

For stablecoins, that means future comparisons between chains will increasingly depend on transaction volume, transfer frequency and settlement activity alongside market capitalization and address counts.

The Q3 report already shows why those dimensions need to remain separate. The network gaining the most supply was not the network adding the most holders, and the largest issuer by distribution actually lost outstanding value during the period.

The Dollar Still Has Almost No Stablecoin Rival

Competition is intensifying between stablecoin issuers and blockchains. At the currency level, there is barely a contest.

Dollar-denominated stablecoins represent 99.3% of all holder addresses in the dataset and added 26.2 million during the quarter.

Euro stablecoins ranked a distant second with 94,600 new addresses. Argentine peso-denominated products added 12,400, while Japanese yen stablecoins gained 4,000.

That leaves the market highly fragmented by issuer and increasingly diverse by blockchain, but overwhelmingly concentrated around one underlying currency.

The most revealing Q4 checkpoints are now outside the established leaders. HyperEVM enters the quarter with $7 billion in stablecoins, RLUSD with 0.8% of global supply, and BNB Chain with 28.7% of holder addresses.

Whether those positions begin producing growth across both capital and distribution will show which of Q3’s fastest movers are building durable stablecoin markets rather than leading a single metric.
