Stablecoin Supply Forecast Hits $4 Trillion as Big Tech Payment Trials Expand : Bitwise Cio

Stablecoin supply could reach $4 trillion by 2030, rising sharply from about $300 billion today, according to Bitwise Chief Investment Officer Matt Hougan. The outlook is tied to early testing by large technology firms exploring blockchain-based payout systems for global workers and digital creators.

DoorDash and Meta Stablecoin Payment Pilots

Hougan highlighted that DoorDash is partnering with Stripe to test stablecoin payouts for roughly 10 million delivery workers across more than 40 countries. At the same time, Meta is rolling out similar payout systems for creators in the Philippines and Colombia using blockchain networks including Solana and Polygon, targeting an estimated 200 million global creators.

Although current volumes remain small, Hougan emphasized that these pilots demonstrate how stablecoins could scale across global labor and content platforms.

Stablecoin Use Case Focused on Payment Simplicity

Hougan noted that the key advantage of stablecoins is not lower cost but operational simplicity. A single wallet system removes the need for banking infrastructure and currency conversions, making cross border payments faster and more direct for companies managing millions of transactions.

Stablecoin Market Size and Institutional Expansion

The total stablecoin market has already crossed $302 billion, led by Tether USDt and USD Coin. Payment companies are also expanding into blockchain settlement, with Western Union and Visa reporting large-scale stablecoin activity across global payment networks.

Hougan said widespread adoption by major platforms could make stablecoins a core infrastructure layer for global payroll and digital commerce, accelerating their role in mainstream financial systems.
