Ripple (CRYPTO: XRP) Prime’s institutional clients can now trade BTC options on Bullish—the second-largest crypto-settled market by open interest—with RLUSD as the collateral. The integration went live on April 29 through Bullish (NYSE: BLSH | BLSH Price Prediction), the publicly listed exchange that has been Ripple Prime’s longtime derivatives partner.
For Ripple Prime—which cleared over $3 trillion in transactions in 2025—this adds options on top of the spot, perpetuals, and futures access its clients already had. For RLUSD, it marks the first time Ripple’s stablecoin has been used as collateral for BTC options trading on a regulated U.S. exchange. Now, Ripple Prime clients can deploy capital through existing sub-accounts without additional KYC.
Inside Ripple Prime’s New BTC Options Access on Bullish
The Ripple Prime and Bullish partnership isn’t new. Ripple Prime clients have been trading Bullish’s spot, perpetuals, and dated futures through the same setup. The April 29 update adds BTC options, which means clients can trade them with no second account, no extra onboarding, or separate workflow.
Bullish accepts stablecoins as collateral, including Ripple’s own RLUSD. A desk that already holds RLUSD on Ripple Prime can use it directly as margin against an options position on Bullish—without converting it first.
Both companies also flagged cross-venue margin support, though it isn’t live yet. When it goes live, institutions will be able to manage collateral across exchanges and over-the-counter desks from one account, freeing up capital that’s currently tied up venue by venue.
That’s a real upgrade for desks trading across multiple exchanges, but the bigger reason this deal matters is what Bullish brings to it.
Why Bullish’s BTC Options Market Is a Big Deal for Ripple Prime
Bullish only added BTC options to its offering in October 2025. In that time, its open interest has crossed $3 billion, putting the venue second only to Deribit, ahead of OKX, Binance, and CME. Deribit still leads the field with around $26 billion in open interest.
Bullish is regulated in the U.S. The exchange trades on the NYSE under BLSH and holds a New York State Department of Financial Services charter. For desks that need a regulated U.S. counterparty, Bullish offers something Dubai-based Deribit can’t.
Ripple Prime is the other half of the equation. It came out of Ripple’s 2025 acquisition of Hidden Road, a prime broker that handles trade execution and clearing for big institutional clients. The platform now clears over $3 trillion a year for more than 300 of them. That makes the partnership vital on both sides, and it’s why RLUSD’s role in the deal matters.
Why RLUSD Wins Big From Ripple’s Bullish Deal
Bullish chose RLUSD over USDT and USDC as collateral for its BTC options market. Those two stablecoins—Tether’s USDT and Circle’s USDC, the two largest in crypto—dominate institutional collateral on almost every major venue, so the pick stands out.
Ripple announced a similar integration with OKX on April 29. RLUSD went live on OKX across more than 280 trading pairs and was accepted as institutional-grade margin collateral. That gave RLUSD margin status on two regulated exchanges on the same day.
Meanwhile, RLUSD’s supply has been growing at a steady pace. The stablecoin’s market cap passed $1.6 billion in late April, up from $132 million a year ago. RLUSD is now a margin asset alongside USDT and USDC on two regulated venues—most stablecoins never reach that level of institutional access.
What the Deal Means for XRP
The Bullish deal is a win for RLUSD, however, for XRP, the impact is much smaller. Bullish picked RLUSD as the collateral, and Ripple Prime has gained another product to offer its institutional clients. The only XRP tie-in is the XRP Ledger burn—every RLUSD transaction on XRPL burns 0.00001 XRP. Even scaled to SWIFT, Visa, and Mastercard combined daily volume, that’s only about 0.0075% of XRP supply burned annually.
With only that fraction of each transaction burning, the deal carries no real weight for the XRP token itself. XRP demand comes from elsewhere—ETF buying and institutions holding the token directly, rather than routing activity through Ripple’s infrastructure.
