Aave now controls roughly three-quarters of the Tether Gold supply circulating through decentralized finance, with XAUT deposits across DeFi crossing the $100 million mark for the first time in early September 2026.

The combined balance reached $102.9 million across approximately ten venues, research data shows. Aave captured 74.2% of those deposits, routed primarily through its V3 and V4 markets.

How fast Aave pulled ahead

Aave's XAUT balances rose from about $40 million in early June 2026 to roughly $76.7 million by mid-August — a 91.7% increase in roughly ten weeks, according to the research underlying the figures.

The growth has been uneven across Aave's deployments. The newer V4 market drew about $8 million in net inflows over a 90-day window, capital that did not arrive from thin air: earlier venues saw corresponding outflows over the same period. The pattern suggests existing XAUT holders are rotating into V4 rather than bringing fresh positions onto Aave's books.

Where the rest sits

Uniswap's V3 pools remain the primary venue for secondary trading of the token, holding approximately $16.5 million in XAUT liquidity in mid-2026. The exchange's share of total DeFi deposits, however, has compressed steadily as borrowers migrate toward lending products and away from spot venues.

On Aave, XAUT functions as a standard ERC-20 collateral asset. A depositor posts tokens, borrows stablecoins against them and retains full exposure to the underlying gold price. The research notes that Aave has successfully processed liquidations of XAUT collateral during recent market volatility, with no reported failures in the oracle or liquidation engine tied to the asset.

How big is the footprint?

The lending base remains modest relative to the broader tokenized-gold complex. XAUT used as collateral on DeFi represents about 1.5% of the combined market capitalization of XAUT and PAXG, the two leading tokenized bullion products tracked by major digital-asset data providers.

Concentration is the other defining feature. With Aave controlling 74.2% of XAUT deposits, the lending market for tokenized gold is effectively a single-protocol venue — a structural feature with both efficiency and counterparty implications for any institutional allocator weighing tokenized bullion.

Why the new mint matters

Tether issued roughly 119,670 additional XAUT tokens in late September 2026 — a single batch worth approximately $495 million and backed by physical gold held in Swiss vaults, the research shows.

That single issuance is several times larger than the entire existing DeFi deposit base. The research flags an unresolved analytical question: does the mint reflect genuinely new demand for tokenized bullion from outside crypto, or is it primarily a reclassification of gold already held on Tether's balance sheet being moved onto a public, on-chain ledger?

The distinction matters for any read on adoption. Fresh external demand should, over time, translate into both broader DeFi utilization and a more even distribution of deposits across protocols. A balance-sheet reshuffle would do neither.

What to watch next

The metric to monitor is the gap between issuance and on-chain usage. If a meaningful share of the freshly minted XAUT migrates into Aave's lending markets over the coming quarters, the 1.5% utilization figure should begin to climb and Aave's effective monopoly over tokenized-gold collateral will harden further. If not, the issuance will sit largely outside DeFi and the existing concentration profile will hold.
