Rootstock: Bitcoin lending yields may unlock next institutional demand

Bitcoin’s next institutional push may not hinge on yet another spot-buying wave, RootstockLabs argues. In a report from the Bitcoin infrastructure developer, the firm suggests that lending, yield generation, and balance-sheet financing could become a new channel for using Bitcoin—turning existing holdings into productive financial capital rather than keeping BTC idle.

The report estimates that only about 1.5% of Bitcoin’s supply is currently used in lending and Bitcoin-native finance, even as identifiable institutional investors hold roughly 3.9 million BTC. RootstockLabs argues that directing more of those holdings into regulated, structured financial activity could increase demand for BTC without changing its fixed supply.

Key takeaways

• RootstockLabs estimates around 1.5% of Bitcoin’s supply participates in lending and Bitcoin-native finance, suggesting substantial room to expand.
• Identifiable institutional investors reportedly hold about 3.9 million BTC—potential “dry powder” for balance-sheet and credit strategies.
• The report highlights two utility paths: earning returns on existing BTC holdings and using Bitcoin alongside fiat liabilities to improve corporate financing efficiency.
• A hypothetical scenario in the report shows how yield on existing holdings could translate into additional BTC-denominated earnings, not a forecast of new BTC demand.
• RootstockLabs acknowledges financialization risks such as leverage buildup and custody concentration, but argues Bitcoin’s on-chain verifiability can reduce some counterparty exposure.

From store of value to financial utility

RootstockLabs frames Bitcoin’s evolution as a shift from a narrow narrative—primarily a store of value—to broader financial utility. According to the report, two categories are most likely to drive the next phase of institutional engagement.

First, the report points to the ability to generate returns on existing BTC holdings. That includes lending and structured credit approaches where BTC can function as collateral or be used within Bitcoin-native financial products.

Second, RootstockLabs highlights a balance-sheet mechanism: pairing Bitcoin with fiat-denominated liabilities. The idea is that institutions may use Bitcoin in financing structures that help optimize liquidity and capital efficiency, potentially reducing the friction of funding real-world operations while still maintaining exposure to BTC.

In both cases, the logic is similar: more Bitcoin can be “put to work” without requiring issuers or markets to absorb entirely new supply. The report’s emphasis is on expanding financial roles for BTC that already sit with institutions.

What the report’s numbers are actually saying

RootstockLabs offers a hypothetical scenario to illustrate the scale of potential BTC earnings from existing holdings. In the scenario, institutional Bitcoin holdings double to 7.8 million BTC. If 5% of those holdings earned a 5% annual yield, institutions would generate 19,500 BTC per year.

Importantly, the report characterizes this as a return calculation on existing holdings rather than a prediction of how many new BTC would be demanded overall. That distinction matters for readers trying to translate the analysis into market expectations: the mechanism could increase activity and returns for holders, but it does not automatically imply the same magnitude of spot accumulation.

The report also draws an analogy to gold’s trajectory. Just as gold developed additional uses beyond its role as a monetary asset—spanning industries like jewelry and electronics—RootstockLabs argues Bitcoin could similarly grow demand through uses in financial markets.

Risk trade-offs: leverage, custody, and enforceability

Any attempt to turn Bitcoin into more conventional financial collateral brings its own risk questions. In comments attributed to Tony DiCarlo—director of institutional propositions at RootstockLabs and author of the report—RootstockLabs acknowledges that financialization “carries real risks.” DiCarlo points to issues that commonly arise around scarce assets when they are used within leveraged systems, including fractional reserves, rehypothecation, and the potential for excess leverage.

He argues, however, that Bitcoin’s design can mitigate parts of those concerns. In his view, collateral can be verified on-chain, liquidation rules can be encoded into the structure of products, and the supply of collateral cannot be diluted. Still, he flags other risks that institutions will need to manage: borrower defaults, custody failures, and legal enforceability.

Volatility also cuts both ways. DiCarlo notes that Bitcoin’s price swings can intensify leverage risks—something lenders and credit structures would need to account for through margining, collateral requirements, and liquidation mechanics.

A real-world example of collateralized borrowing

To illustrate how institutions might use Bitcoin without surrendering custody of their BTC exposure, DiCarlo points to MARA’s reported $750 million in Bitcoin-backed loans. The filing cited in the report coverage states that MARA used Bitcoin as collateral to help finance a planned power plant acquisition in Ohio, allowing the company to retain its Bitcoin holdings while funding infrastructure.

The point for investors and market participants is that these structures are designed around the same core idea RootstockLabs outlines: BTC can be used as a financing input for real-world activities, with exposure retained through collateralization rather than outright sale.

Custody concentration and why ownership mechanics matter

Beyond leverage and credit risk, RootstockLabs also emphasizes a structural concern: as institutions adopt Bitcoin more deeply, holdings could become concentrated among a small set of custodians. DiCarlo’s perspective highlights an asymmetry between different “ownership” models.

While spot Bitcoin exchange-traded funds (ETFs) have been a major driver of institutional participation, DiCarlo warns that “shareholders own shares, not coins.” That distinction, in his view, means that operational control may still depend heavily on intermediaries—raising the possibility that the practical custody footprint could concentrate among a few large providers.

Even so, DiCarlo argues that Bitcoin’s decentralized architecture remains a foundational advantage. Holders can retain control of their keys, and the use of Bitcoin can reduce the number of intermediaries required for certain financial services. In his words, fewer “middlemen” can translate into reduced counterparty risk and lower fees, while also attracting builders who design products around these properties.

Bitcoin’s defining trait is that nobody owns it and you don’t need an intermediary to use it. Holders keep control of their keys and because there are fewer middlemen, financial services built on Bitcoin can carry less counterparty risk and fewer fees. Those advantages draw users in and they reward the builders who design around them.

What to watch next

If RootstockLabs is right about the scale of unused lending and Bitcoin-native finance, the next signal won’t just be spot demand—it will be growth in institutional credit and yield strategies that use BTC as collateral. Investors should watch how products manage volatility and enforceability, and whether custody concentration becomes a bottleneck as financialization expands.
