The lending venue land grab for tokenized stocks

Four lending markets accept xStocks as collateral as of May 2026. They came online in a specific order: Kamino, Morpho, Jupiter Lend, then Euler. The order is not accidental. The borrow asset each venue paired with the collateral is not accidental either.

Together the sequence reads as a customer arc. The first venue validated that anyone wanted to borrow against tokenized stocks at all. The second validated that sophisticated DeFi capital would underwrite the risk on Ethereum. The third pulled in the active-trader segment with leverage. The fourth introduced an institutional-style borrow asset that points at the next customer the market is courting.

What the four venues collectively do not have is a single TradFi treasury desk borrowing through them. The tokenized stock as collateral is still a crypto-native instrument used by crypto-native customers. Reading the order of the rails explains how the market got that way.

Kamino Finance shipped xStocks as collateral first, in late 2025, on Solana. The choice was overdetermined. xStocks’s primary chain is Solana. Kamino is the largest Solana-native lending protocol, running over $1B in RWA deposits by early 2026. The borrow asset was USDC, which is the dominant stablecoin on Solana and the asset every Solana retail user already holds.

That last detail is the customer signal. A lending market that only accepts USDC as the borrow asset is a market built for retail. A user holds tokenized Apple stock, wants to take a loan against it without selling, and gets USDC out. The use case is the same as a Robinhood margin loan, ported onto Solana. The Kamino vault did not require a new stablecoin, a new oracle, or a new risk model. It needed only to accept the new collateral.

Kamino added institutional-grade rails around the market over time. Anchorage provides custody for institutional borrowers who want to access Kamino without holding the collateral directly. Vault curation runs through Gauntlet and Steakhouse, the same risk firms that curate Morpho and Aave vaults. But the venue’s core customer remained the Solana retail user.

First-mover advantage compounded. The Kamino xStocks vault sets the baseline LTV (around 50% on SPYx, lower on single-stock tickers), the baseline borrow rate, the baseline liquidation buffer. Every venue that came after had to either match those parameters or explain why they diverged.

Morpho added xStocks as collateral on Ethereum in Q1 2026. The venue is structurally different from Kamino in three ways that matter.

The structure tells you the customer. Sophisticated DeFi capital that wants to underwrite specific risks chooses Morpho because the protocol lets it. A treasury manager at a yield protocol can deposit USDC into a SPYx-collateral market only, receive a yield premium over generic USDC lending, and accept only the SPYx liquidation risk. The curator does the diligence on the oracle and the collateral.

That same treasury manager cannot do that on Kamino. Kamino pools risk across the protocol; depositing into the platform means underwriting whatever Kamino accepts as collateral. On Morpho, the depositor sees the exact risk and can opt in or out.

Morpho’s xStocks listing also proved the asset class would survive the migration to Ethereum. The same tokenized SPYx that lives natively on Solana exists as a bridged or re-issued version on Ethereum. Both versions are issued by Backed Finance, the Jersey-regulated wrapper factory that Kraken owns. Bridge risk becomes a real risk to underwrite, separate from the underlying equity risk. The curators priced it. Capital flowed in.

Jupiter Lend launched xStocks as collateral in April 2026, with parameters that looked aggressive next to Kamino’s. The headline number was the LTV: up to 3.8x leverage on liquid tickers, well above Kamino’s baseline. The borrow assets included USDC, USDT, and JLP (Jupiter’s LP token), giving traders multiple ways to loop.

Jupiter’s customer is not a holder. It is a trader. The venue’s core product is the DEX aggregator that routes 50% of Solana’s spot volume; the perps platform with up to 100x leverage; the lending market that lets you borrow against anything to size up. Listing xStocks as collateral was a feature for the same user who was already doing basis trades between SPYx spot and SP 500 perps elsewhere on Solana.

The leverage parameters reveal the underlying conviction. Jupiter set the LTV based on its own oracle reliability and its own liquidation engine, which the team had years of data on. They concluded that xStocks could be levered higher than Kamino allowed without breaking the rails. That decision could be wrong, and the next major drawdown will test it. But the public bet is on the table.

Euler shipped xStocks as collateral on May 12, 2026, in a vault curated by Cassa with Agora’s AUSD as the borrow asset. Four signals separate this listing from the three that came before.

The collateral set is Wrapped SPYx and Wrapped STRCx. Wrapped versions are the tokenized stock plus an additional wrapper contract that handles edge cases (corporate actions, dividends, oracle failure). Most lending venues take the bare tokenized stock. Cassa chose to require the wrapped version, which costs the borrower a small layer of friction but isolates the venue from issuer-side operational risk.

The borrow asset is AUSD, Agora’s stablecoin. AUSD has roughly $128M in market cap, against USDC’s $60B-plus. Picking AUSD instead of USDC is a deliberate choice, not a convenience. AUSD’s reserves are managed by VanEck and custodied by State Street. The crypto-native institutional customer who borrows AUSD against tokenized equity collateral is signaling something about which stablecoin infrastructure they trust to hold their debt against.

Cassa is the vault curator. Like Gauntlet on Morpho, Cassa underwrites the parameters and takes the curation fee. Unlike Gauntlet, Cassa is a small team focused on tokenized RWA markets specifically; the xStocks vault is one of its first public products.

The fourth signal is the chain. Euler runs primarily on Ethereum. xStocks on Ethereum exists, but most of the volume is on Solana. A borrower using this venue is choosing to custody on Ethereum despite the worse liquidity. The reason is usually that the borrower’s other positions are already on Ethereum and they value the consolidation more than they value the spread.

Stack the four venues and the customer ladder becomes legible.

Each step in the ladder pulls in a customer the previous one could not reach. Kamino made the asset useful for the largest existing pool of crypto-native users. Morpho extended it to capital that wanted to underwrite specific risk. Jupiter added the leveraged-trader segment. Euler with Cassa pulled in the niche-but-sophisticated customer looking to validate a new stablecoin or a new vault architecture against a real collateral pool.

The conspicuous absence in the ladder is a TradFi treasury desk. None of the four venues has a corporate treasurer borrowing stablecoins against tokenized stock holdings. The reasons are structural: a corporate treasury cannot hold AUSD, cannot custody Wrapped SPYx, and cannot rationalize the regulatory exposure on a balance sheet that has to be audited annually. The rails that would let them do this do not exist yet.

Two pieces would unlock the TradFi step on this ladder. The first is a tokenized-equity lending venue that accepts only fiat-denominated borrow assets, mirroring what BSTBL did for the BlackRock treasury fund. The second is a transfer agent on the collateral side that a corporate auditor recognizes as equivalent to a traditional custodian.

Neither exists today. When one or both do, the customer ladder gets a fifth rung and the press release will reuse the same phrasing that BSTBL got: "BNY Mellon as transfer agent, fiat wire subscriptions, Ethereum only." The audience for that rail will be the same treasurer who is already a candidate for BSTBL.

Until then, tokenized stocks as collateral remain a crypto- native primitive. The four venues that exist were built for crypto-native customers, sequenced from the largest segment to the most specific. The lending land grab is real, but the land being grabbed is a corner of DeFi, not the next leg of institutional capital markets.
