Bitwise Asset Management CIO Matt Hougan argued in a recent memo that moves by Meta and DoorDash into stablecoin payouts are exactly the kind of large-scale adoption catalysts needed to push the total stablecoin supply toward Citigroup's updated bull-case target of $4 trillion by 2030. The memo came as the stablecoin market hit a fresh all-time high of $321 billion in total market cap in May 2026, more than double its level from early 2025.

Citigroup revised its stablecoin projections upward earlier this year, lifting the base case from $1.6 trillion to $1.9 trillion and the bull case from $3.7 trillion to $4 trillion. Hougan called even the base case "actually quite modest," pointing to the pace of institutional and corporate adoption as evidence the higher scenario is achievable. Reaching $4 trillion would require the market to grow roughly 12 times over from current levels in under five years.

The Corporate Pilots Driving the Narrative

Meta launched a USDC stablecoin payout pilot in April 2026 for creators in Colombia and the Philippines, using Solana and Polygon as the settlement networks. The company built the infrastructure in partnership with Stripe and plans to expand to more than 160 countries by the end of 2026. Meta has no plans to issue its own stablecoin; it is plugging into existing USDC infrastructure on public blockchains instead. Creators must provide their own external wallet address, and Meta will not handle local currency conversion on their behalf.

The move marks a sharp contrast with the company's earlier ambitions. Meta's 2019 Libra project, a proposed global stablecoin, collapsed under regulatory pressure. Its follow-up attempt, Diem, was abandoned in 2022. The April 2026 pilot avoids those pitfalls entirely by using USDC, a stablecoin that already operated under existing money transmission frameworks well before the passage of the GENIUS Act, on established public blockchain rails.

DoorDash announced a parallel pilot through Tempo, a payments blockchain co-founded by Stripe and venture firm Paradigm. Tempo launched in March 2026 with a $5 billion valuation after raising $500 million, with backing from Visa, Mastercard, and UBS. DoorDash intends to use the network to pay merchants and delivery workers across more than 40 countries. The scale of that ambition is concrete: DoorDash processed nearly $75 billion in merchant sales in 2025, giving the company substantial payment volume to route through stablecoin rails from day one. DoorDash co-founder Andy Fang said the company sees "real promise with stablecoins transforming financial infrastructure." Stripe's head of Connect and Money Management, Neetika Bansal, described the goal as making global payments "fast, cheap and borderless."

What the On-Chain Data Shows

The market context behind these announcements is significant. USDT holds approximately $185 billion in market cap, accounting for roughly 58 percent of total stablecoin supply. USDC sits at around $78 billion. USDC issuer Circle controls about 25 percent of the total stablecoin market and more than 80 percent of the regulated segment. Stablecoin transfer volume reached $28 trillion in the first quarter of 2026 alone, representing 75 percent of all crypto trading volume. Yield-bearing stablecoins, a fast-growing subcategory, added roughly $4.3 billion in market cap during Q1 2026, representing 22 percent category-wide growth. Citigroup estimates that by 2030, dollar stablecoin issuers could collectively hold $1.2 trillion in US Treasuries, potentially surpassing major foreign sovereign holders.

The passage of the US GENIUS Act contributed to the regulatory clarity underpinning this activity. The law, which cleared the Senate 68 to 30 and the House 308 to 122, established the first federal framework for payment stablecoins in the United States. Qualifying stablecoins must be backed one-to-one by US dollars or low-risk assets and are not classified as securities or commodities under the new rules.

Regional Stakes: Africa and South Asia

The implications are sharpest in markets where remittance costs and unreliable fiat infrastructure are everyday problems. Africa has the highest stablecoin ownership rate among crypto-active users globally, at 79 percent according to the BVNK Stablecoin Utility Report for 2026. Sub-Saharan Africa received $205 billion in on-chain value between July 2024 and June 2025, a 52 percent year-over-year increase, with stablecoins accounting for 43 percent of that activity. Traditional remittance costs in the region average 8.78 percent of the transferred amount. Stablecoin transfers typically cost between 0.5 and 1 percent.

The infrastructure to support this shift is already active, not merely incoming. Flutterwave, one of Africa's largest payments companies, partnered with Polygon Labs in October 2025 to enable real-time USDC and USDT cross-border transfers across 34 countries. Kenya provided additional regulatory grounding that same month by passing its Virtual Asset Service Providers Bill, establishing a licensing framework for crypto businesses and giving stablecoin operators a clear legal pathway into one of Africa's most active digital finance markets.

Chris Maurice, CEO of African crypto exchange Yellow Card, noted that many African banks find stablecoin payments appealing precisely because they enable transactions that "don't have to go through New York," a reference to the US dollar correspondent banking infrastructure that governs most traditional cross-border settlements. Ezekiel Ojewunmi of exchange Quidax added that stablecoin remittances mean "more money ends up in the hands of loved ones."

In South Asia, the stakes are similarly high. India receives more than $120 billion in annual remittances and ranks first globally in the 2026 Crypto Adoption Index. The broader region saw an 80 percent increase in crypto adoption between January and July 2025, reaching approximately $300 billion in transaction volume, a pace that underscores how rapidly demand has outpaced existing financial infrastructure. Pakistan, ranked third globally in the adoption index, lifted its seven-year ban on banks servicing crypto providers in April 2026 and launched a regulatory sandbox earlier in the year. Reports indicate that Pakistan also has a national stablecoin initiative in planning, a development that would represent a significant escalation in sovereign-level engagement with the technology if confirmed. Bangladesh, ranked 14th globally, has no legal framework for crypto but sees documented underground stablecoin use for remittances from Gulf workers.

The Philippines, one of the two markets where Meta's pilot launched, is the world's third-largest remittance-receiving country, taking in approximately $40 billion per year. Its inclusion in Meta's initial rollout signals that the company is targeting high-volume remittance corridors from the outset, not merely large consumer markets.

Meta's planned rollout to 160-plus countries is expected to reach major markets in Africa and South Asia, including potentially Nigeria, Kenya, India, and Pakistan. The gap between a creator receiving USDC on Polygon and converting it to local currency at a reasonable rate depends on whether local on-ramp and off-ramp infrastructure, including peer-to-peer desks and exchanges like Yellow Card and Quidax, can scale to meet demand.

Citigroup's bull case of $4 trillion explicitly requires favorable regulation in multiple jurisdictions beyond the United States. How quickly India, Bangladesh, and other large emerging markets move toward clear stablecoin frameworks will be one of the most consequential variables in whether that ceiling gets reached before 2030.
