Stablecoin weekly: Big-3 rebounds $1.91B as USDC adds $1.76B (2026)

The latest seven-day snapshot reverses three straight weeks of Big-3 contraction. USDT + USDC + DAI rose $1.910B to $261.687B, and USDC supplied $1.759B of that gain. USDT's asset-level change was only +$143.2M, but Tron absorbed +$949.3M while Ethereum lost $637.5M—a large rail rotation under a small headline delta.

Snapshot cutoff: August 26, 2026, 08:00 (UTC-05:00). The DeFiLlama snapshot was read at about 08:08 local time; its current and circulatingPrevWeek fields are compared below. BTC and ETH prices were refreshed at about 08:10 local time. Rounded figures may not reconcile exactly.

Bottom line

Asset	Current supply	Previous-week supply	7-day change	Change
USDT	$183.178B	$183.035B	+$143.2M	+0.08%
USDC	$73.734B	$71.975B	+$1.759B	+2.44%
DAI	$4.775B	$4.767B	+$8.1M	+0.17%
USDT + USDC + DAI	$261.687B	$259.777B	+$1.910B	+0.74%

DeFiLlama's asset-level snapshot supplies the current and prior-week values. 1

USDC accounts for about 92% of the combined increase. Last week's issue recorded a $428.7M decline; this week's $1.910B rebound is the first clear Big-3 expansion in the recent sequence. DAI's $8.1M rise is small relative to the other two assets.

The practical read is broad USDC expansion with a separate USDT Tron rotation. A rising chain balance can still reflect issuer inventory, exchange routing, or application deployment rather than new dollars ready to buy risk assets.

The chain map: USDC fills Ethereum and Hyperliquid; USDT returns to Tron

The following tables use the same fields for each asset. Other chains is the residual of the full DeFiLlama chain list, not an estimate of bridge activity. A positive chain delta is an endpoint-balance increase; it does not identify the path taken.

USDT

Chain	Current supply	7-day change
Ethereum	$73.521B	-$637.5M
Tron	$91.471B	+$949.3M
Arbitrum	$842.8M	-$10.4M
Solana	$2.835B	-$25.0M
Avalanche	$342.5M	-$40.0M
BSC	$9.183B	+$4.3K
Hyperliquid L1	$102.5M	+$1.9M
Polygon	$805.6M	-$28.0M
Aptos	$976.9M	+$0.9K
Plasma	$713.5M	+$41.8M
TON	$585.7M	-$95.0M
Mantle	$452.4M	+$14.9M
OP Mainnet	$206.8M	+$13.4M
Other chains	$1.139B	-$42.4M

Tron's $949.3M gain more than offsets Ethereum's $637.5M loss and leaves USDT up only $143.2M overall. TON's $95.0M decline and Avalanche's $40.0M decline are secondary drains. The pattern flips last week's Ethereum-led USDT rebound and restores a Tron-heavy distribution.

USDC

Chain	Current supply	7-day change
Ethereum	$47.122B	+$871.7M
Tron	$27.9M	+$0.0K
Arbitrum	$2.206B	-$11.9M
Solana	$7.012B	+$239.6M
Avalanche	$429.4M	-$24.7M
Base	$4.260B	+$30.7M
BSC	$1.582B	+$68.0K
Hyperliquid L1	$6.602B	+$566.1M
Polygon	$1.696B	+$64.8M
Aptos	$234.6M	+$13.6M
Stellar	$324.9M	-$9.4M
Other chains	$2.238B	+$18.3M

Ethereum's $871.7M USDC gain is the single largest chain increase in the Big-3 tables. Hyperliquid L1 adds another $566.1M, and Solana adds $239.6M. Those three rails account for most of USDC's $1.759B expansion. Avalanche and Arbitrum are modest offsets rather than a competing destination.

DAI

Chain	Current supply	7-day change
Ethereum	$4.134B	+$22.6M
Tron	$0.0K	+$0.0K
Arbitrum	$18.9M	+$158.8K
Solana	$510.3K	+$0.0K
Avalanche	$10.8M	+$122.0K
Base	$0.0K	+$0.0K
BSC	$31.1M	+$0.0K
Hyperliquid L1	$0.0K	+$0.0K
Polygon	$505.1M	-$14.4M
Aptos	$0.0K	+$0.0K
Stellar	$0.0K	+$0.0K
Plasma	$0.0K	+$0.0K
Other chains	$74.2M	-$284.3K

DAI's $8.1M rise is an Ethereum gain against a Polygon decline. It does not change the Big-3 reading. 1

A chain endpoint balance is not a bridge-flow ledger. Without the source and destination pair, the tables cannot say whether USDT moved from Ethereum to Tron through a bridge, whether an issuer rebalanced inventory, or whether users traded inside an application.

Issuer and large-wallet events: heavy USDC minting, a $2B USDT burn, and exchange routing

The public alert set verified the following high-signal events inside the seven-day window. The timestamps below are converted to UTC-05:00. Whale Alert is a selected feed, not a complete mint-and-burn ledger, so the table is a sample of large issuer and deployment events rather than a census.

Asset	Amount and direction	Chain	Local time	Wallet category	Source
USDT	1.000B minted at Tether Treasury 2	Tron	Aug 21, 08:58	Issuer treasury	Whale Alert
USDT	1.000B minted at Tether Treasury 3	Tron	Aug 21, 09:57	Issuer treasury	Whale Alert
USDT	2.000B burned at Tether Treasury 4	Ethereum	Aug 21, 10:43	Issuer treasury	Whale Alert
USDT	500.000M transferred from Tether Treasury to Binance 5	Tron	Aug 21, 09:01	Issuer-to-exchange operation	Whale Alert
USDT	150.000M transferred from Tether Treasury to an unknown wallet 6	Tron	Aug 25, 04:34	Issuer treasury deployment	Whale Alert
USDC	120.000M transferred from USDC Treasury to Coinbase 7	Ethereum	Aug 22, 02:43	Issuer-to-exchange operation	Whale Alert
USDC	152.951M burned at USDC Treasury 8	Solana	Aug 25, 09:13	Issuer treasury	Whale Alert
USDC	250.000M minted at USDC Treasury 9	Solana	Aug 26, 00:12	Issuer treasury	Whale Alert
USDC	169.028M transferred from Unknown Whale 1 to Aave 10	Ethereum	Aug 25, 19:10	Unknown wallet to protocol	Whale Alert

On August 21 local time, Whale Alert also recorded a third $1.000B Tether Treasury mint on Tron and several large Binance–Treasury USDT transfers on Tron and Ethereum. Across the same week, the feed showed a long series of $250M USDC Treasury mints on Solana plus smaller Ethereum mints, so the single $250M row above stands for a repeated inventory pattern rather than the only mint.

The reconciliation still matters. Verified USDC treasury mints in the public feed run well above DeFiLlama's $1.759B circulating increase, and the $2.000B Ethereum USDT burn sits beside Tron mints that leave USDT only $143.2M higher at the asset level. Treasury issuance and burns are inventory and operational evidence. They do not by themselves count as end-user buying power. The Coinbase transfer and the Aave transfer show possible deployment destinations, but neither proves that traders bought spot assets with the newly visible balances.

No complete issuer-level burn ledger, and no comparable Maker/Sky DAI mint-or-burn event, was verified from the public event sources for this window.

Market cross-check

Asset / indicator	Snapshot	7-day or latest change
BTC	$78,252.42	+20.08% over 7 days; -0.71% over 24 hours
ETH	$2,453.16	+26.75% over 7 days; -0.46% over 24 hours
Crypto Fear & Greed	65, Greed	Previous reading in this series window: 46, Fear (Aug 18 local)
Combined USDT + USDC exchange balance	Data temporarily unavailable	No verified seven-day public series

CoinPaprika supplied the BTC and ETH prices and percentage changes. 11 12 The Fear & Greed API's latest reading was timestamped August 25 at 19:00 local time; the August 18 local reading of 46 is the prior Fear classification still visible in the same eight-day pull. 13

BTC and ETH both posted large seven-day gains while the Big-3 supply expanded. Fear & Greed moved from Fear into Greed over the same stretch. The coincidence is stronger than last week's price rebound against a shrinking stablecoin base, but exchange-held stablecoin balances are still missing, so the link from expanded circulating supply to exchange buying power remains incomplete.

What the snapshot can—and cannot—say

Are stablecoins growing in aggregate? Yes. USDT, USDC, and DAI rose from $259.777B to $261.687B, a $1.910B increase after last week's $428.7M decline.
Is capital concentrating on a rail? Partly. USDC rose on Ethereum, Hyperliquid L1, and Solana together. USDT concentrated on Tron while Ethereum and TON lost balances. The week is multi-rail expansion for USDC and a Tron-led redistribution for USDT.
Is that capital available to buy risk assets? Only partly established. Circulating supply and risk prices moved in the same direction, and issuer-to-exchange USDC and USDT transfers appeared in the alert feed. The missing exchange-balance series and the gap between treasury mint totals and circulating deltas still leave end-user buying power uncounted.

Pair-by-pair bridge flows for USDT, USDC, and DAI were not available: the DeFiLlama Bridges endpoint returned a paid-plan prompt instead of a usable seven-day table. A comparable public series for combined USDT plus USDC balances held on major exchanges was also not verified. 14

The next confirmation to watch is whether USDC's Ethereum and Hyperliquid gains hold while Tron USDT stops absorbing most of the USDT redistribution. If both stay elevated into the next snapshot, this week's move looks more like durable liquidity return than a one-week inventory flush.

Method note: Supply figures use DeFiLlama's asset and chain snapshots. Issuer and wallet events come from Whale Alert's public event records and are not treated as proof of end-user demand. Market figures use the linked public APIs. All displayed times are in UTC-05:00.
