XRP and SOL surpass BTC and ETH in the preferred holdings of institutional investors in 2025

For many years, the strategy of organizations with crypto was quite simple: buy Bitcoin, possibly allocate a small portion to Ethereum, and ignore the rest of the market.

By 2025, that pattern has been rewritten.

While Bitcoin still holds the position as the largest asset in terms of total market cap, the core story of the year lies in a structural shift toward where new capital flows are choosing to go.

Year-end data from CoinShares shows that the “Bitcoin-only” era is giving way to a new tiered order: Ethereum is solidified as a core holding, while XRP and Solana emerge as the first truly institutional “big altcoins.”

Capital flows reverse: from Bitcoin to alternative networks

The numbers clearly reflect changing investor behavior. In 2025, Bitcoin investment products attracted $26.98 billion in inflows, but this is 35% lower than the record pace of 2024.

Conversely, capital into alternative networks increased at an unprecedented rate. Ethereum products saw a 138% increase in inflows, while XRP and Solana respectively grew by about 500% and 1,000%, nearly doubling the existing asset size within a year.

This divergence indicates a maturing market, moving away from speculative diversification toward a leaner structure focused on a select group of top assets.

Ethereum “graduation” and the pace of new major altcoins

Data from 2025 shows that institutional capital allocators have fundamentally redefined Ethereum. From being viewed as a high-risk satellite asset around Bitcoin, Ethereum has “graduated” to become a mainstay in portfolios.

According to CoinShares, Ethereum attracted $12.69 billion in net inflows in 2025, up from $5.33 billion the previous year. This 138% increase occurred even as Bitcoin inflows cooled, implying that investors are increasingly willing to hold independent views of the two assets rather than trading them as a correlated pair.

With total AUM of Ethereum products reaching $25.7 billion by year-end, this network has achieved a scale that makes it a necessary component in diverse digital asset portfolios.

However, the most significant revaluation of risk happened at the next level. XRP and Solana, which have competed for third place for many years, experienced outsized capital inflows. XRP products attracted $3.69 billion in 2025, about five times the $608 million of 2024. Solana was even more impressive with $3.56 billion, compared to just $310 million a year earlier, a tenfold increase.

What’s notable isn’t just the growth rate but the relative scale compared to the existing market. Early 2025, the investment ecosystem for XRP and Solana was still modest. By year-end, inflows into each asset were nearly equal to their entire year-end AUM, around $3.5 billion each.

Financially, this represents a “replacement ratio” close to 100%. While Bitcoin inflows account for about 19% of AUM and Ethereum 49%, XRP and Solana have almost “renewed” their entire capital base, indicating a wave of new institutional investors entering for the first time.

The decline of the “long tail”

If 2025 was the breakout year for the top players, for the rest of the market, it’s a wake-up call.

Excluding Bitcoin, Ethereum, XRP, Solana, multi-asset baskets, and short Bitcoin hedge products, the “remaining altcoins”—including familiar names like Cardano, Litecoin, Chainlink, and new contenders like Sui—saw significant capital outflows.

This group attracted only $318 million in 2025, down 30% from $457 million in 2024.

This contraction reflects an increasingly stringent investment environment. In previous cycles, retail enthusiasm often spread across hundreds of small tokens, creating broad rallies. But the ETF and ETP era operates differently: legal hurdles and liquidity requirements create high barriers for new products.

As a result, asset management firms hesitate to launch products for tokens lacking clear regulation or deep liquidity. Without these “regulated shells,” institutional capital finds it difficult to access the long tail.

The outcome is a “winner-takes-all” dynamic. Capital concentrates in the four assets with liquid, managed investment products, widening the liquidity gap between the “big group” and the “small group,” creating a self-reinforcing cycle: products attract capital; more capital deepens liquidity; deeper liquidity makes the wave of institutional participation even safer.

Meanwhile, assets outside the “privileged circle” face liquidity droughts, making it harder to attract passive flows—an increasingly influential factor in crypto market growth.

Sample portfolio for 2026

The crystallization of this order has a major impact on how digital asset portfolios are constructed from 2026 onward.

The “Bitcoin-only” strategy can still protect cautious investors but is gradually losing market share to multi-asset models.

Financial advisors and asset managers, who previously found it hard to justify allocations outside Bitcoin, now have data to support a diversified core. The new standard model is shifting toward a weighted basket: Bitcoin as a digital commodity and anchor; Ethereum as the foundational smart contract layer; Solana and XRP as high-growth “satellites,” representing specific bets on speed, scalability, and payment utility.

CoinShares data supports this view: Bitcoin is becoming a lower-beta asset—stable, large-scale, but slow-growing—while alpha is increasingly sought in the “big new players.”

Notably, the $105 million inflow into short Bitcoin products, with total AUM reaching $139 million, indicates maturity in tool usage. Organizations are not only accumulating passively; they are also hedging.

The ability to short leading assets while long-holding high-beta satellites opens up sophisticated relative-value trades—something previously mainly associated with crypto-native hedge funds, not regulated asset managers.

Risks of a too-narrow market

While the “big new players” being created signals maturity, it also brings risks.

Capital concentration in just four assets makes the entire ecosystem’s health increasingly dependent on the performance of a few networks. The “speed” of inflows into Solana and XRP—where inflow equals total AUM—is a double-edged sword. Rapid expansion means many holders are new investors.

Unlike Bitcoin’s “hodler” base, which has endured multiple 80% drawdowns, new institutions may be more sensitive to price swings. If narratives shift or legal risks re-emerge, even the standard products that previously attracted capital could accelerate withdrawals.

Further out, the “long tail starvation” raises questions about innovation. If capital is only directed toward the big players, new protocols will struggle to reach the valuation velocity needed to attract talent and secure network security. The industry risks becoming “big-headed,” with trillions of USD value anchored in four chains, while the rest of the ecosystem stagnates.
