The shift reflects growing competition for stablecoin distribution, particularly on derivatives exchanges where tokens serve as collateral. According to Crystal Intelligence, Bybit recorded the largest reduction, shedding $1.66 billion in USDT while adding $315 million of RLUSD. Binance cut $987 million in USDT and added $223 million in USDC, while OKX reduced by $899 million and added $273 million in USDC.
Meanwhile, the 19 institutions added approximately $1.9 billion in competing tokens, including $569 million of USDC and $493 million of RLUSD. Across the wider market, USDT's circulating supply fell $647 million, or 0.4%, to around $184 billion. RLUSD rose 59% to $2.5 billion, while USDC gained $687 million.
Derivatives platforms have become key battlegrounds. Hyperliquid, a leading derivative exchange, increased USDC deposits by $1.5 billion to approximately $7.2 billion under an arrangement with Coinbase and Circle that shares reserve-linked income. About three-quarters of that quarterly increase came from one cluster of linked wallets, Crystal found.
Deribit, owned by Coinbase, added $365 million in USDC and expanded its rewards program to approximately 70 additional countries in August, paying customers monthly based on minimum daily USDC holdings. Bybit's RLUSD increase followed a rewards campaign launched with Ripple in July.
The competition is costly for issuers. Circle generated about $1.4 billion in revenue in the first half of 2026 but spent $819 million (59%) on distribution and transaction costs and $473 million on operating expenses, leaving a net profit of $103 million -- just seven cents per revenue dollar. Circle expanded distribution through a five-year agreement with Binance that included a $100 million investment from the exchange.
Other issuers are adopting similar revenue-sharing models. PayPal-backed PYUSD offers a 4.5% incentive on up to $1 billion in deposits through USD.AI, while Stripe-owned Bridge launched Open USD in September with a model designed to return most reserve income to partners.
Despite losing exchange holdings, USDT retains dominance in payments. A separate Allium report estimated stablecoins processed $482 billion in classified payments from January to September 2026, with USDT accounting for 84% -- approximately $405 billion. Payment value rose 45% year-on-year, and transaction counts climbed 71% to 1.04 billion, with the average payment declining from $544 to $462. September recorded $72 billion in payments, the highest monthly total. The Tron blockchain handled about two-thirds of classified payment value, preserving a major distribution network for USDT.
