Tether’s USDT Surpasses $150B as Report Predicts 600% Stablecoin Growth by 2030

Stablecoin adoption is growing, as demonstrated by Tether’s USDT, which surpassed $150 billion in circulating supply for the first time on 12 May 2025. The USDT increased its market cap by $11 billion from the beginning of this year alone.

The USDT dominates the stablecoin market with a 62% market cap, reinforced by a 3.79% growth over the last month. Its closest competitor, USDC, also witnessed modest growth at 1.23%. Other stablecoins, too, have witnessed a growth in their adoption numbers.

For instance, BlackRock’s BUIDL token, representing tokenised U.S. Treasuries, grew by 19.3% to a $2.89 billion market cap; MakerDAO’s DAI also increased by 12.07% as per DefiLlama’s data.

A large chunk of Tether’s USDT supply increase is attributed to mints on the Tron network, which added $12.2 billion in stablecoins over the last three months, a substantial amount when compared to the $2.3 billion increase on the BNB Smart Chain and $1.7 billion on Ethereum during the same timeframe.

From 0 to $150B.

Stablecoins to Overtake Current Crypto Market Cap?

A recent report published by Citi’s Future Finance think tank predicts that the stablecoin market might soon overtake the current total market cap of all cryptocurrencies, which, as it currently stands, is just over $3.5 trillion, as per CoinGecko.

The report states that the year 2025 could be stablecoin’s “ChatGPT moment,” where stablecoins gain widespread adoption, spurred by regulatory advancements. Citi predicts that, as a base, the total outstanding supply of stablecoins could grow up to $1.6 trillion.

In case of a bull run, Citi predicts that the number could be as high as $3.7 trillion.

However, the report also notes that if the authorities do not address adoption and integration challenges, the growth may stall out at $500 billion. As per the current size of the stablecoin market ($242 billion), Citi’s base prediction would correlate to a 600% increase in stablecoin market cap by 2030 and 1500% in the case of a bull run.

Additionally, the investment bank predicts that the role of stablecoins might expand beyond just being tokenised cash for crypto traders to a mainstay for payments and remittance facilitation.

Furthermore, Citi predicts that stablecoin issuers might purchase up to $1 trillion of US treasuries by 2030 to back their stablecoins.

Predictions Hinge on Favourable Stablecoin Regulations

While favourable regulations shape Citi’s stablecoin market cap prediction, the topic remains highly contested, especially in the US, where lawmakers have yet to pass the stablecoin regulation bill, the GENIUS Act.

The bill only managed to snag 49 of the 60 votes that it needed to clear the chamber, with two Republican senators, Senator Josh Hawley and Senator Rand Paul, rejecting the bill.

Dem Senator Mark Warner explained, “While we’ve made meaningful progress on the GENIUS Act, the work is not yet complete, and I simply cannot in good conscience ask my colleagues to vote for this legislation when the text isn’t finished.”
