Arkis and Spark Announce Institutional Prime Credit Collaboration

Digital asset markets are maturing.

As institutional participation accelerates and returns compress, the limiting factor for professional trading firms is no longer access to markets — it is access to reliable, scalable credit. Yet credit infrastructure in crypto remains fragmented across venues, governed by opaque risk practices, and constrained by asset-level margining that limits capital efficiency.

Arkis was built to change this.

Today, we’re announcing a strategic collaboration with Spark, under which Spark deploys institutional liquidity through the Arkis credit framework to power Spark Prime, a new generation of capital-efficient, collateralized, on-chain lending for institutions. This partnership combines Spark’s institutional liquidity and risk governance with Arkis’s unified margin and credit framework — enabling predictable, portfolio-level credit across CeFi and DeFi environments.

Unified Credit for CeFi and DeFi Portfolios

Through this collaboration, Arkis becomes the unified credit and margin layer underpinning Spark Prime, a new institutional offering by Spark.

Rather than treating collateral, risk, and margin in isolation at each venue, Arkis evaluates borrower portfolios holistically across DeFi protocols, centralized exchanges, and qualified custodians. This enables institutional borrowers to deploy collateral seamlessly across environments while operating within transparent, rules-based risk controls.

Spark provides liquidity and defines risk parameters. Arkis enforces them through its unified margin and risk engine.

The result is predictable, portfolio-level credit that unlocks significantly more usable borrowing capacity from the same collateral.

Spark Investment in Arkis for Institutional Alignment 

As part of this collaboration, the Spark Foundation has made a $4m strategic equity investment, aligning long-term incentives around the development of institutional-grade credit infrastructure.

This investment reflects shared principles between both entities:

• Conservative, rules-based risk methodology

• Transparent collateral evaluation and exposure monitoring

• Portfolio-level margining over asset silos

• Governance frameworks suitable for institutional capital

Spark is deploying institutional liquidity through Arkis, with Arkis serving as the unified credit and margin layer for Spark Prime.

Spark to Scale Arkis Loan Book: First Step Toward Institutional-Grade Digital Credit Markets

Spark expects to significantly expand capital allocations deployed through the Arkis platform, targeting up to $500 million in credit capacity during 2026, with ambitions to grow well beyond that as institutional participation in digital markets continues to scale.

Digital asset credit and prime brokerage are converging toward institutional standards. 

Through Spark Prime, Arkis becomes the unified credit and margin layer that those standards require — replacing fragmented, venue-level risk with a single, portfolio-wide framework that scales across CeFi and DeFi.

This partnership marks a shift in how institutional credit is deployed in digital markets: predictable, transparent and governed under one coherent risk model. As capital scales, the infrastructure is already in place.
