Three major catalysts boost altcoin ETFs, will the second half of 2025 welcome a crypto "ETF Summer"?

The Bitcoin ETF ignited last spring, and the "Crypto ETF Summer" is expected to arrive in the second half of this year.
With altcoin ETFs for SOL, XRP, DOGE, and others waiting for approval from the U.S. SEC, the number of submitted crypto spot ETFs has surpassed 70. Currently, the Solana staking ETF has successfully launched, a group under Trump is promoting a "crypto blue-chip portfolio" ETF, and the SEC is planning to establish unified listing rules, possibly preparing for a concentrated approval.
Unlike the on-chain experiment of DeFi Summer in 2020, this "ETF Summer" comes from Wall Street and Congress.
Three Catalysts for "ETF Summer": Trump, Universal Standards, Staking ETFs
The wave of Bitcoin spot ETFs that surged last year is far from over.
Among the 2,000 funds managed by the world's largest asset management giant BlackRock, the Bitcoin spot ETF $IBIT, set to launch in early 2024, has surprisingly jumped to the third position in expected annual returns, only behind the IWF, which tracks the largest 1,000 growth companies in the U.S., and the EFA, which covers developed market stocks outside of the U.S. and Canada.

The success of the Bitcoin ETF has sounded a huge gong, and the battlefield for crypto ETFs has shifted from single-point breakthroughs to a comprehensive rollout.
Bloomberg ETF analyst James Seyffart recently predicted that a new wave of ETF approvals will arrive in the second half of 2025: among them, the approval probabilities for LTC, SOL, and XRP are 95%, while DOGE, HBAR, Cardano, Polkadot, and Avalanche are expected to have a 90% approval probability.

It is worth noting that the review deadlines for these altcoin ETFs are mostly concentrated in the fourth quarter of this year. Once approved in bulk, the crypto market will welcome "ETF Summer." Currently, the three main catalysts driving this wave are beginning to take shape.
First Catalyst: Trump's Involvement, Political Capital Boosting Crypto ETFs
Trump has written "crypto" into his political script, launching a "crypto combination punch," attacking from all angles with crypto projects WLFI, meme coins, stablecoins, and crypto ETFs.
In March, Trump's media technology group signed a binding cooperation agreement with crypto exchange Crypto.com and asset management company Yorkville America Digital, planning to launch a series of crypto ETFs under its brand Truth.Fi.
In the following months, Trump's camp has been actively engaged:
- On June 3, Truth Social submitted a Bitcoin ETF application;
- On June 16, Truth Social submitted applications for Bitcoin and Ethereum ETFs, with a holding structure of 75% Bitcoin and 25% Ethereum;
- On July 8, Truth Social applied for a "blue-chip crypto ETF," including Bitcoin (70%), Ethereum (15%), Solana (8%), Cronos (5%), and XRP (2%).
Such a high-frequency ETF application rhythm undoubtedly ignited the first fire for crypto ETFs.
Second Catalyst: SEC Establishing Universal Listing Standards, Potentially Becoming the "Accelerator" for Approvals
With the surge in crypto ETF applications, the U.S. SEC is considering a faster approval framework. Crypto journalist Eleanor Terrett disclosed last week that the SEC is working on establishing universal listing standards for cryptocurrency ETFs, aiming to significantly speed up the listing process for these funds.

According to the preliminary plan, if tokens meet the standards, issuers will not need to go through the lengthy 19b-4 approval process but only need to submit S-1 documents and wait 75 days. The discussed selection criteria may include market capitalization, degree of decentralization, and wallet distribution, among others.
Bloomberg senior ETF analyst Eric Balchunas stated, "It is entirely reasonable for the SEC to establish universal listing standards, which is also why we are optimistic about the high approval probabilities of most mainstream coins reaching 95%. We expect these rules to be lenient enough that most of the top 50 coins can successfully issue ETFs."
Another Bloomberg analyst, James Seyffart, predicts that this framework draft may be released as early as this month, with formal implementation expected in September or October.
If this framework is successfully introduced, it will likely open the floodgates for crypto ETF approvals and signify a key step forward for the SEC in regulating crypto assets.
Third Catalyst: Staking ETFs Breaking the Ice, Bridging On-Chain Yields with Traditional Markets
Ethereum staking ETFs have always been a focal point of market attention. Since February of this year, several institutions, including 21Shares, Grayscale, Fidelity, Bitwise, and Franklin, have successively submitted applications to the SEC to incorporate spot Ethereum ETFs into staking mechanisms. However, as of now, the related proposals have not yet been approved.
While waiting, an "unexpected player" has taken the lead: on July 2, the first U.S. Solana staking ETF (REX-Osprey Solana + Staking ETF, trading code $SSK) officially launched for trading. This ETF aims to track the performance of Solana while generating yields through on-chain staking.
It operates as a Class C company, circumventing regulatory challenges related to staking, providing investors with a compliant way to earn staking yields. On its first day of trading, SSK's trading volume reached $33.914 million, significantly outperforming Solana futures ETFs, XRP futures ETFs, and the average performance of regular ETFs, but falling short of the trading volume levels of Bitcoin and Ethereum spot ETFs.
The launch of this ETF marks a dual breakthrough in regulation and product structure, potentially triggering a wave of applications for PoS staking ETFs.

The three catalysts intertwine, and the crypto "ETF Summer" is gradually revealing its initial state. Along with the wave of coin-stock linkage, more innovative plays may emerge.
