TL;DR: The interesting stablecoin story in 2026 isn't crypto — it's plumbing. Card spend on stablecoin rails roughly quadrupled year over year, real-world stablecoin payments hit an estimated $350–550B, and the money is going local: intra-country volume climbed from ~50% to ~75% of payments in two years. Brazil is the proof of concept — a real-pegged stablecoin went from near-zero to ~$400M/month once it plugged into PIX. And the incumbents you'd expect to get disrupted — Visa, Stripe, Shopify — aren't fighting this. They're quietly rebuilding the payments stack on stablecoin rails.
