Tether’s USDT Exceeds $150B as Forecast Anticipates 600% Expansion in Stablecoin Crypto market by 2030

The adoption of stablecoins is on the rise, exemplified by Tether’s USDT, which crossed the $150 billion mark in circulating supply for the first time on 12 May 2025. USDT’s crypto market capitalization has grown by $11 billion since the start of this year alone.

USDT leads the stablecoin trading market with a 62% trading market cap, bolstered by a 3.79% increase in the past month. Its nearest rival, USDC, also saw slight growth at 1.23%. Other stablecoins have also experienced a rise in their adoption figures.

For example, BlackRock’s BUIDL crypto token, which represents tokenized U.S. Treasuries, grew by 19.3% to a market cap of $2.89 billion; MakerDAO’s DAI also rose by 12.07%, according to DefiLlama’s data.

A significant portion of the USDT supply increase is due to mints on the Tron network, which contributed $12.2 billion in stablecoins over the past three months, a considerable figure compared to the $2.3 billion growth on the BNB Smart Chain and $1.7 billion on Ethereum during the same period.

Could Stablecoins Surpass the Current Trading market Cap?

A recent report released by Citi’s Future Finance think tank suggests that the stablecoin crypto market may soon exceed the current total crypto market cap of all cryptocurrencies, which is just over $3.5 trillion, as per CoinGecko.

The report indicates that 2025 could be stablecoin’s “ChatGPT moment,” where widespread adoption occurs, driven by regulatory improvements. Citi forecasts that the total outstanding supply of stablecoins could reach up to $1.6 trillion as a baseline.

In a optimistic scenario, Citi anticipates the figure could climb to as much as $3.7 trillion.

Nonetheless, the report highlights that if regulatory bodies do not tackle the challenges of adoption and integration, growth could stagnate at $500 billion. Based on the current state of the stablecoin market ($242 billion), Citi’s base forecast would imply a 600% increase in stablecoin market cap by 2030, and a staggering 1500% in a uptrend context.

Additionally, the investment bank foresees that the role of stablecoins may expand from serving merely as tokenized cash for crypto traders to becoming essential for payment and remittance solutions.

Furthermore, Citi anticipates that stablecoin issuers might acquire up to $1 trillion worth of U.S. Treasuries by 2030 to base level their stablecoins.

Predictions Depend on Positive Stablecoin Regulations

While favorable regulations influence Citi’s stablecoin market cap predictions, the subject is hotly debated, particularly in the U.S., where lawmakers have yet to approve the stablecoin compliance bill, the GENIUS Act.

The bill fell short with only 49 of the 60 votes needed to pass, with two Republican senators, Josh Hawley and Rand Paul, opposing the measure.

Democrat Senator Mark Warner remarked, “While we’ve made significant progress on the GENIUS Act, the work is incomplete, and I cannot in good conscience ask my colleagues to vote for this legislation when the text isn’t finalized.”
