Fidelity is preparing to roll out its stablecoin, Fidelity Digital Dollar (FIDD), with a 1:1 peg to the US dollar and reserves made up of cash, cash equivalents, and short-term US Treasury bonds. Bloomberg reported that the token is expected to become available to both institutional and individual investors in the coming weeks. Fidelity has chosen Ethereum for the launch, a move that places FIDD directly inside the infrastructure used across DeFi.
Issued through Fidelity’s digital asset structure
FIDD will be issued by a national trust bank operating under Fidelity Digital Assets. That entity received a conditional operating license from the US Office of the Comptroller of the Currency in December. Fidelity’s reserve design is also tied to regulation: the company plans to limit backing assets to those defined under the GENIUS Act. In practice, that means highly liquid, low-risk instruments intended to support a predictable product for payment and custody use cases, especially for institutional clients.
Mike O’Reilly, president of Fidelity Digital Assets, said stablecoins can be used in payment and settlement workflows. The product is being positioned around real-time operation, seven-day availability, and low cost. Because it is being built on Ethereum, FIDD can be transferred to any ETH address and can interact with a wide range of DeFi protocols. That network choice is central to Fidelity’s market entry plan.
Entering a market dominated by Tether and Circle
Fidelity is stepping into a sector with entrenched leaders. Tether and Circle together control about 82% of the stablecoin market. Products launched by other global firms, including PayPal and Ripple, have so far made only limited inroads. Tether’s repositioned USA₮ product is focused only on the US market and compliance, adding another layer of competition.
Ethereum remains the main chain for stablecoin distribution. Data from RWA.xyz shows that 56% of the market operates on Ethereum, while Tron accounts for 28% and Solana nearly 5%. Coingecko puts total stablecoin market value at $312 billion. USDT alone represents 60% of that total, with supply at $186 billion. Matching that scale will be difficult, but Fidelity enters with more than 50 million customers and over $15 trillion in assets, giving FIDD a clear profile as a product to watch in the institutional segment.
Its approach is straightforward: use Ethereum’s reach, keep the structure tightly aligned with compliance, and target institutional adoption from the start.
