USDT vs USDC: Choosing the Right Stablecoin for Tokenized Stock Trading

Stablecoins are essential tools in the digital asset ecosystem, providing a stable link between volatile cryptocurrencies and fiat currencies, most commonly the US dollar. For investors engaging with innovative financial products like tokenized US-listed stocks, understanding which stablecoin to use is important. Two prominent stablecoins, Tether (USDT) and USD Coin (USDC), offer distinct characteristics in terms of backing, transparency, and regulatory approaches. On GM Markets, we simplify this choice, allowing you to focus on the opportunities in tokenized equities.

This post will examine the differences between USDT and USDC, providing a detailed comparison of their attributes. We will then explain how GM Markets unifies stablecoin deposits under our proprietary USDF balance, abstracting away the need for you to manage multiple stablecoins when trading tokenized stocks on our platform.

What Are Stablecoins and Why Are They Important for Tokenized Stocks?

Stablecoins are a class of cryptocurrency designed to minimize price volatility. They achieve this by pegging their value to a stable asset, typically the US dollar. This pegging mechanism, often maintained through reserves of traditional assets, makes stablecoins an important tool for navigating the cryptocurrency market without constant exposure to its inherent price fluctuations.

For tokenized stocks, stablecoins play a critical role. Tokenized stocks offer exposure to traditional equities on a blockchain, bringing benefits like fractional ownership and 24/7 trading. However, if the medium of exchange used to buy or sell these tokens were highly volatile, it would undermine the very stability that makes traditional stock exposure appealing. Stablecoins provide the necessary price stability for transactions, ensuring that when you buy a tokenized share of a company like Apple or Tesla, the value of your payment remains consistent with its fiat equivalent. You can learn more about how tokenized stocks work on our platform.

This stability is crucial for investors who want to manage their exposure to equity markets directly, without the added complexity of managing a fluctuating base currency. On GM Markets, we leverage stablecoins to facilitate seamless trading of tokenized US-listed stocks and ETFs, empowering you to invest with confidence in a predictable environment.

Tether (USDT): Market Presence and Reserve Details

Tether (USDT) launched in 2014 and quickly became the first widely adopted stablecoin. It has consistently maintained its position as a leading stablecoin by market capitalization and daily trading volume. As of July 12-14, 2026, USDT's market capitalization stands between approximately $183.67 billion and $184.3 billion. Its 24-hour trading volume during the same period has been observed in the range of $41.64 billion to $58.91 billion, demonstrating its deep liquidity and widespread use across the global crypto market.

Tether publishes quarterly attestation reports prepared by BDO Italia, a global independent accounting firm. Its Q1 2026 attestation report, covering the period up to March 31, 2026, disclosed a net profit of $1.04 billion and an increase in its reserve buffer to a record $8.23 billion. The reserves backing USDT are primarily composed of US Treasury bills, which constituted approximately 80% of reserves as of Q1 2026, totaling around $141 billion in direct and indirect exposure. Other components of Tether's reserves include secured loans, Bitcoin (approximately $7 billion), and physical gold (around $20 billion). More details can be found in BDO Italia's reports and on Tether's transparency page.

Tether announced in March 2026 that it had selected an unnamed "Big Four" accounting firm to conduct its first full financial audit of its reserves, a process that formally commenced in Q1 2026. This move aims to provide continuous oversight of assets, liabilities, and internal controls, confirming that USDT is 1:1 backed by liquid reserves with an over-collateralization buffer exceeding $5 billion, and that there is zero exposure to commercial paper.

USD Coin (USDC): Transparency and Regulatory Compliance

USD Coin (USDC) was launched in September 2018 by the Centre consortium (founded by Coinbase and Circle) and is now solely issued by Circle. USDC is pegged 1:1 to the US dollar and is known for its commitment to regulatory compliance and transparency.

Every USDC token is fully backed by US dollar-denominated assets held in segregated reserves at regulated financial institutions, such as BNY Mellon. These reserves primarily consist of a mix of cash and short-term US Treasury bonds. Circle provides weekly disclosures of reserve holdings and mint/burn flows. A "Big Four" accounting firm provides monthly third-party attestations, prepared according to AICPA standards, confirming that the value of USDC reserves exceeds the amount in circulation. The Circle Reserve Fund (USDXX), which holds a significant share of USDC reserves, is an SEC-registered 2a-7 government money market fund managed by BlackRock. You can review Circle's transparency reports for detailed information.

Circle, a regulated fintech company based in the United States, is registered as a money services business with FinCEN and 46 state regulators, complying with state money transmission laws. USDC also adheres to the European Union's Markets in Crypto-Assets (MiCA) regulations and Canadian Securities Administrators (CSA) standards, allowing for "passportability" across the EU. In the US, the Guiding and Establishing National Innovation for US Stablecoins Act (GENIUS Act), signed in July 2025, codified requirements for payment stablecoins, including 1:1 reserves and monthly attestations. USDC's existing structure already met these conditions. Circle IPO'd on the NYSE on June 5, 2025, under the ticker CRCL, and files quarterly (10-Q) and annual (10-K) reports with the SEC, providing public insight into its reserve composition, custodial relationships, and compliance. Circle has also received OCC approval for its national trust bank, further enhancing its regulatory standing. For more information on regulatory filings, refer to the SEC's website.

As of July 14, 2026, USDC's market capitalization is approximately between $72.77 billion and $73.13 billion. Its 24-hour trading volume as of the same date ranges from about $9.66 billion to $14.02 billion.

USDT vs. USDC: A Direct Comparison for Tokenized Stocks

Tether (USDT) and USD Coin (USDC) are the two largest stablecoins, both pegged to the US dollar at a 1:1 ratio. They offer price stability crucial for trading volatile assets like tokenized stocks. However, they differ significantly in their market presence, transparency, and regulatory approaches.

USDT (Tether)

• Market Dominance and Liquidity: USDT holds the largest market capitalization among stablecoins, approximately $183.67 billion to $184.3 billion as of July 12-14, 2026. It boasts high trading volume and liquidity, making it a practical choice for active traders and for facilitating fast transactions and arbitrage opportunities across most exchanges.
• Multi-chain Availability: Launched in 2014, USDT is available natively on 10 major blockchains, including Ethereum, Solana, and Tron, with additional bridged versions across over 80 networks. This offers flexibility in transaction speeds and costs. Transactions on networks like Tron (TRC-20) are known for speed and low fees.
• Transparency and Regulatory Scrutiny: USDT has faced persistent scrutiny regarding the exact composition and transparency of its reserves. Historically, Tether has been criticized for a lack of full audits, instead providing quarterly attestations. In 2021, Tether paid a $41.6 million fine for misrepresenting its reserve backing. Its reserve composition, while primarily U.S. Treasuries, also includes secured loans, gold, and Bitcoin. Under the European Union's Markets in Crypto-Assets (MiCA) regulation, which saw stablecoin provisions become applicable on June 30, 2024, Tether has not applied for the necessary authorization. As a result, regulated EU platforms are prohibited from offering non-authorized e-money tokens (EMTs) like USDT to public customers in the European Economic Area (EEA). This led to major EU-regulated exchanges delisting USDT spot trading pairs between late 2024 and March 2025. Individuals can still legally hold USDT in self-custody wallets and use it on decentralized exchanges (DEXs) or in DeFi protocols, as these activities fall outside MiCA Title V's scope.

USDC (USD Coin)

• Transparency and Regulatory Compliance: USDC is known for its commitment to regulatory compliance and transparency. It provides monthly reserve reports audited by major accounting firms, detailing its backing. Circle has secured an Electronic Money Institution license in the EU, making USDC compliant under MiCA, allowing it to remain listed on regulated European exchanges.
• Reserve Backing: USDC's reserves are primarily backed by highly liquid cash and short-term U.S. Treasuries, held in segregated accounts with regulated financial institutions.
• Institutional Trust and Adoption: Launched in September 2018, USDC is often considered an institutional-grade stablecoin, favored by businesses and investors prioritizing certainty and long-term stability. It has seen growing adoption, particularly in the US, and has partnerships with entities like Coinbase, Visa, and BlackRock. USDC is also being tested by Mastercard and integrated by Stripe for crypto payouts.
• Market Capitalization and Liquidity: USDC has a smaller market capitalization, approximately $72.77 billion to $73.13 billion as of July 14, 2026, compared to USDT. It also has a slightly lower trading volume and less global adoption than USDT, which can result in comparatively lower liquidity on some platforms.

For buying tokenized stocks, the choice between USDT and USDC often depends on individual priorities. USDT's liquidity and widespread acceptance make it practical for active traders who prioritize fast transactions and broad market access. USDC, with its emphasis on transparency and regulatory compliance, may be more appealing to those who value certainty and long-term stability, particularly institutional investors or those operating in heavily regulated jurisdictions.

GM Markets' USDF: Unifying Your Stablecoin Experience

GM Markets' USDF serves as a unified stablecoin balance, simplifying deposits and management for our users. We designed USDF to abstract away the complexities of managing multiple stablecoins and different blockchain networks.

• Unified Balance: USDF unifies your USDC and USDT deposits into a single, consistent balance on the GM Markets platform. This means you do not need to choose between USDC or USDT directly when funding your account; both contribute to your USDF balance.
• 1:1 Backing: Every USDF token is backed 1:1 by either USDC or USDT across various blockchain networks, ensuring the stability and reliability of your funds.
• Supported Chains: Deposits and settlements involving USDF occur seamlessly across major blockchain networks including Base, Arbitrum, Ethereum, and Optimism. This allows for flexibility in how you fund and manage your tokenized stock positions.

The benefits of USDF for our users include simplified management, as you interact with a single balance rather than tracking multiple stablecoins across different chains. This also facilitates seamless cross-chain operations and liquidity management. Additionally, while not directly a USDF feature, GM Markets abstracts gas fees. Our smart account pays native gas, and we bill the equivalent in USDC/USDF from your balance. This means you never need to hold a native chain token for gas and never see a separate gas line, further enhancing the seamless experience provided by USDF. You can find more details on our pricing and fees page.

Frequently Asked Questions

What am I actually buying when I buy a tokenized stock on GM Markets?

You are buying a tokenized representation of one share, fully backed 1:1 by an actual share held in custody on your behalf by a regulated broker-dealer. The token tracks the economic value of the underlying (price, dividends, corporate actions) through its on-chain NAV. It lives in your embedded wallet, so you retain custody and can move, trade, lend, borrow, or supply it as liquidity across DeFi. It behaves like a stock for price exposure and like a crypto asset for composability.

What are the total fees on a trade?

The trading fee ranges from 10 to 20 basis points (0.10% to 0.20%). The default is 20 bps, dropping toward 10 bps as your 14-day trading volume grows through our VIP ladder. The fee is included in the quoted price, so the "You will receive" line is the final amount. Gas is abstracted (billed in USDF from your balance; no native token needed). Deposits and withdrawals are free across every rail (Apple Pay, card, bank, stablecoin). You can view our full fee schedule on the pricing page.

Do I receive dividends? What happens during corporate actions?

Yes, you receive the economic equivalent of dividends. A dividend is used to buy more of the underlying shares, and the token's on-chain NAV rises accordingly. You see the dividend value reflected in the token's price rather than as a separate cash distribution. Other corporate actions such as splits, special distributions, spin-offs, mergers, or name changes are absorbed into the token's on-chain NAV so your position tracks the underlying exactly.
