Tether’s USDt Reaches $187B in Q4 as Rivals Shrink in Crypto Downturn

Despite a market downturn sparked by a major liquidation on Oct. 10, Tether’s dollar-pegged stablecoin USDt reached a record market capitalization of $187.3 billion in Q4 2025, rising by $12.4 billion from the prior quarter. The latest quarterly report shows USDt gaining share as rival stablecoins faced headwinds: Circle’s USDC held roughly flat, while Ethena’s synthetic dollar USDe declined by about 57% in market capitalization during the period. The data underscores how stablecoins continued to anchor on-chain activity even as larger crypto markets cooled amid liquidity stress and risk-off sentiment.

Key takeaways

• USDt reached a record $187.3 billion market cap in Q4 2025, expanding by $12.4 billion QoQ as it widened its dominance in the stablecoin space.
• Onchain activity surged: average monthly active USDt wallets rose to 24.8 million, roughly 70% of all stablecoin-holding wallets, with quarterly transfer volume hitting $4.4 trillion and 2.2 billion on-chain transfers.
• Reserve assets grew to $192.9 billion by end-Q4, up $11.7 billion versus the prior quarter, with US Treasuries exposure climbing to $141.6 billion and positioning the issuer among the largest holders globally.
• Market competition softened for some peers: Circle’s USDC drifted but remained largely unchanged; Ethena’s USDe collapsed by about 57% in market cap during the quarter.
• New US-market stablecoin initiatives and partnerships: USAt, a GENIUS Act–compliant USD stablecoin, launched in January with a $10 million initial supply on Ethereum, and Tether expanded USDT and XAUT into Opera’s MiniPay wallet to broaden access in emerging markets.
• Illicit-use controls intensified: Tether highlighted ongoing efforts to curb misuse through collaborations with TRM Labs and Tron to monitor and freeze illicit funds.

Market context: The quarterly data arrive as liquidity conditions have remained uneven following a wave of volatility in October. Stablecoins continued to serve as a stabilizing layer for on-chain activity and settlement, even as questions about reserve quality and regulatory oversight persist. The report tracks how demand for USDt interacts with broader market sentiment and DeFi usage, particularly after the market stress observed in Q4 2025.

Why it matters

The quarterly snapshot reinforces the central role of USDt in enabling efficient on-chain activity, especially when price swings or macro risk reduce appetite for other assets. A record market cap signals sustained institutional and user reliance on a highly liquid, widely accepted stablecoin as a medium of exchange and a hedge against volatility. Yet the divergence among stablecoins—USDC staying flat while USDe contracted—illustrates continued fragmentation in the space, where issuer quality, reserve management, and regulatory alignment can rapidly shift relative strengths.

Reserves and exposure to U.S. Treasuries are a focal point for investors and regulators alike. The end-of-quarter reserve total of $192.9 billion, with $141.6 billion of US Treasuries exposure, places the issuer among the largest holders of Treasuries and invites ongoing scrutiny of risk management and liquidity coverage. The growth in on-chain activity—nearly 25 million active USDt wallets and trillions in transfer volume—highlights the asset’s role not only as a settlement layer but also as a backbone for liquidity provisioning within DeFi and cross-border payments frameworks.

Beyond the numbers, the push into the US market via USAt and collaborations to integrate USDt with mainstream wallets point to a longer-term strategy focused on regulatory alignment and consumer access. The GENIUS Act–compliant structure aims to ease broader adoption while preserving compliance, signaling a potential pathway for stablecoins to scale within established financial rails. At the same time, enhancements to illicit-use monitoring reflect a broader industry push to balance innovation with risk controls as usage patterns evolve and cross-border activity intensifies.

What to watch next

• Follow the Q1 2026 reserve disclosures for changes in US Treasuries exposure and total reserves.
• Monitor regulatory developments around GENIUS Act–compliant stablecoins and any approvals or guidance affecting USAt adoption.
• Track on-chain activity metrics (wallet counts, transfer volumes) to gauge whether USDt usage sustains its growth trajectory amid shifting risk sentiment.
• Observe any new partnerships or wallet integrations that broaden USDt and XAUT adoption, particularly in emerging markets.

Market reaction and key figures

Tether’s quarterly report shows USDt continuing to lead the stablecoin sector, with $187.3 billion in market capitalization by the end of 2025, up $12.4 billion from the prior quarter. The outcome underscores a disciplined growth pattern for the issuer, even as more volatile corners of the crypto market retraced. The stability of USDC, contrasted with the decline of USDe, illustrates how the space remains sensitive to issuer dynamics and market demand for different hedging instruments.

On-chain activity painted a picture of robust utilization. The report notes an average of 24.8 million monthly active USDt wallets, accounting for about 70% of all stablecoin-holding wallets. Quarterly transfer volume surged to $4.4 trillion, and the total number of on-chain transfers reached 2.2 billion, signaling broad engagement across payments, remittances, and decentralized finance channels. The data suggests USDt’s liquidity and reach were significant drivers of cross-border settlement and on-chain commerce during a period of broader risk-off sentiment.

Reserve composition remained a focal point of investor attention. Total reserves rose to $192.9 billion, up $11.7 billion from the previous quarter, while net equity stood at $6.3 billion. A notable development was the increase in US Treasuries exposure to $141.6 billion, positioning Tether among the largest holders of Treasuries and underscoring a conservative, asset-backed approach designed to preserve liquidity and trust in the face of market stress. The emphasis on treasury holdings is a signal to markets and regulators alike that the issuer prioritizes balance-sheet resilience alongside growth in use cases for USDt.

Why it matters

The record Q4 figures reinforce stablecoins’ centrality to crypto markets and on-chain finance, especially when liquidity and attention shift toward risk management. USDt’s growth in market capitalization, wallets, and transfer volumes suggests that users value a familiar, highly liquid reliable asset for settlement and liquidity provisioning. It also underscores the ongoing strategic emphasis on reserve quality and regulator-friendly structures that can sustain broader adoption.

At the same time, the relative stagnation of USDC and the decline of USDe highlight persistent fragmentation within the stablecoin ecosystem. The market’s trajectory may hinge on issuer credibility, regulatory clarity, and the ability to demonstrate robust compliance and risk controls without sacrificing accessibility or speed. The launch of USAt and the expansion of USDt into mainstream wallets and partners through Opera indicate a broader effort to bridge traditional financial rails with crypto-native infrastructure, a trend that could shape stablecoin usage and policy discussions in the coming year.

Finally, the commitment to curb illicit use—through collaborations with TRM Labs and Tron to monitor and freeze funds—remains a crucial component of the narrative. As stablecoins become more deeply integrated into everyday financial activity, transparent governance, auditable reserves, and proactive compliance will be critical to sustaining confidence among users, developers, and regulators alike.
