Stablecoins tightened their dominance across crypto casinos and prediction markets in 2025, with USDT and USDC increasingly serving as the default settlement assets for online wagering.
Research shows stablecoins processed $27.6 trillion in transfer volume in 2024, accounting for roughly 30% of all crypto transaction activity, and that momentum has extended decisively into gambling platforms.
The broader crypto gambling market reached an estimated $81 billion in 2025, with $26 billion in digital currency bets placed in the first quarter alone and projections ranging between $65 billion and $81 billion for 2026.
Gamblers favour stablecoins because they eliminate currency volatility risk, ensuring payouts reflect wager outcomes rather than price swings in assets such as bitcoin or ether.
USDT commands roughly 60% of total stablecoin market capitalisation, while USDC holds more than 24%, and both tokens benefit from deep liquidity and low-cost transfers across networks including Tron.
Stablecoins are also becoming the primary settlement layer for prediction markets tied to elections, sports and macroeconomic events, where price stability is critical for contract accuracy.
While regulatory frameworks such as MiCA in Europe and proposed US legislation may influence issuance and compliance standards, industry surveys show more than 65% of blockchain gaming respondents expect stablecoins to remain central to onboarding and transaction flows in 2026.
