Why Stablecoins Now Dominate Crypto Betting – and What It Means for ETH

Stablecoins Quietly Became the Default Crypto Bet

Two years ago, when I recommended stablecoins for betting, people looked at me like I was missing the point. “Why use crypto if you are just going to peg it to the dollar?” By mid-2026, those same people have USDT as their primary sportsbook deposit method. The shift happened faster than anyone predicted – including me.

Stablecoins now account for over 70% of all crypto betting transactions. That is not a gradual trend; it is a takeover. Bitcoin’s dominance in crypto gambling fell from 88% to 77% over the course of 2025, and Tether absorbed the bulk of that migration. Ethereum holds steady at about 9%, a respectable but clearly secondary position. The market has rendered its verdict: bettors want blockchain speed and low fees, but they do not want their bankroll repriced by market volatility between Saturday’s deposit and Monday’s withdrawal.

The irony is that most stablecoins run on Ethereum. USDT and USDC are ERC-20 tokens. When someone deposits USDT at a sportsbook via Arbitrum, they are using Ethereum’s infrastructure – just not Ethereum’s native token. The network wins even as the token loses share.

The Numbers Behind Stablecoin Dominance

The data tells a clear story of accelerating adoption. Bitcoin’s share of crypto gambling volume sat at 88% in early 2025 and closed the year at 77%. That 11-percentage-point decline did not go to Ethereum or Litecoin or any other volatile asset. It went to stablecoins, primarily USDT.

Ethereum’s 9% share has remained remarkably stable. This is partly because the bettors who use native ETH tend to do so deliberately – they want the smart contract functionality, the DeFi integration, or the speculative upside that stablecoins cannot provide. The casual depositor who just wants a fast payment method has largely migrated to USDT.

The overall crypto gambling market generates $81.4 billion in annual revenue, which means stablecoins process well over $55 billion of that volume. Crypto sportsbooks account for about 17% of all global iGaming wagers, and within that segment, stablecoin usage is even higher than the market average because sports bettors tend to hold funds for longer periods between bets, making volatility exposure more costly.

One statistic that captures the magnitude: sports betting interest in crypto gambling jumped from 3.15% to 14.83% during 2025 alone. That growth disproportionately flowed into stablecoin-denominated activity, because new entrants – people trying crypto betting for the first time – overwhelmingly choose the option that behaves like the money they already understand.

Why Operators Prefer Stablecoin Deposits

Mike Peplow, COO of payment processor Paysecure, has noted that regulation has become an ever-increasing concern for iGaming operators, and that technology solutions connecting different parts of the player journey are growing quickly. Stablecoins fit that narrative perfectly. They simplify the operator’s balance sheet in ways that volatile assets do not.

When a sportsbook accepts a 1 ETH deposit, it takes on immediate price risk. That 1 ETH might be worth $3,200 AUD today and $2,800 AUD tomorrow. The sportsbook must either hold the ETH (accepting the risk), immediately convert to fiat (paying exchange fees and spreads), or hedge the position (adding operational complexity). Each option carries costs that erode the operator’s margin.

A 1,000 USDT deposit carries no price risk. It is worth $1,000 today and $1,000 tomorrow. The sportsbook can hold it indefinitely without hedging, pay out winnings in the same denomination, and reconcile its books without referencing any exchange rate. Accounting becomes straightforward, compliance reporting simplifies, and the operational overhead of managing a multi-asset treasury drops substantially.

Operators also benefit from reduced player complaints. A bettor who deposits 1 ETH, loses 0.5 ETH in bets, and then watches the remaining 0.5 ETH drop 20% in value will feel like the platform took more than it did. The loss from volatility blends psychologically with the loss from betting, creating negative sentiment that has nothing to do with the platform’s service quality. Stablecoin balances avoid this entirely – if you lose 500 USDT in bets, the remaining balance is exactly what you expect.

Ethereum’s Role in a Stablecoin-Dominated Market

The question every ETH bettor should ask is whether native ETH still has a purpose in betting, or whether stablecoins on Ethereum have made it redundant. The answer is nuanced, and it depends on what you want from your betting experience.

For pure payment functionality – depositing and withdrawing – stablecoins win on every practical dimension. Stable value, wide acceptance, low fees on L2, no volatility management. If your only goal is getting money onto and off a sportsbook efficiently, USDT on Arbitrum is the optimal choice, full stop.

But Ethereum offers capabilities that stablecoins do not. Decentralised betting dApps operate entirely in native ETH, using smart contracts for escrow, payout, and dispute resolution. These platforms do not support stablecoin balances – the entire system runs on ETH. If you want to use prediction markets, peer-to-peer wager protocols, or any platform that leverages Ethereum’s programmability beyond simple transfers, native ETH is required.

There is also a speculative argument. Bettors who are bullish on ETH’s price trajectory can use native ETH deposits as a leveraged play: if you win your bet and ETH appreciates, your returns compound. This is a deliberate strategy that some sophisticated bettors employ – holding volatility exposure alongside betting exposure. It is not for everyone, but it is a valid reason to choose native ETH over stablecoins.

The likely future is coexistence. Stablecoins handle the mass market – casual bettors, sports bettors, anyone who prioritises simplicity. Native ETH serves the crypto-native segment – DeFi users, dApp bettors, and those who actively want price exposure. The two audiences overlap but do not fully converge, and both will continue growing as the total crypto gambling market expands. For practical guidance on how to use stablecoins within the Ethereum ecosystem for betting, the market size analysis provides the broader context of where these trends are heading.
