Bitwise Chief Investment Officer Matt Hougan says global stablecoin supply could jump from just over 300 billion dollars today to 4 trillion dollars by 2030. He bases that call on rising real-world use and early big tech trials. He also points to new regulatory frameworks that now recognize stablecoins in major economies.
His projection sits near the top of existing research, but it lines up with Citigroup’s bull case for the sector. Citi’s 2030 report sets a base-case forecast of 1.9 trillion dollars in stablecoin issuance and a bull case of 4 trillion dollars.
That revision came after supply and usage grew faster than the bank’s earlier models expected. Hougan argues the market is now tracking closer to that upper range as stablecoins move from trading tools to payment rails.
From $300 Billion Today to Multi-Trillion Supply
The current starting point is already large by crypto standards. Data cited by Binance and the World Economic Forum shows stablecoin market cap near 300 to 310 billion dollars in early 2026.
At the same time, Visa and on-chain trackers estimate 2025 stablecoin transaction volume above 30 trillion dollars. That figure rivals or even exceeds major card networks.
Hougan says that kind of activity shows stablecoins now serve more than speculative trading. People and businesses use them for remittances, onchain savings, and dollar access in countries with weaker banking options. He argues that as more everyday payments and settlement move onto blockchains, supply will need to scale by an order of magnitude.
Big Tech Pilots and New Use Cases
Big tech adoption is a crucial component of Hougan’s $4 trillion vision. He cites tests of stablecoin rewards and settlement on networks like Solana and Polygon conducted by companies including Meta, DoorDash, and Stripe. These initiatives focus on two areas where standard railroads are expensive and slow: freelance workers and international payments.
Hougan believes that if global platforms roll out stablecoin options at scale, millions of new users could join the ecosystem quickly. That growth would add to demand already coming from DeFi and tokenized assets. It would also build on onchain treasury tools that companies and funds already use.
In that scenario, he says, today’s 300 billion dollar supply “leaves a lot of room to run.” Citi estimates that a 1.9 trillion dollar base-case market could support about 100 trillion dollars in yearly transactions by 2030, and potentially 200 trillion dollars in a bull case.
