Analysts tracking the crypto exchange-traded fund (ETF) market have raised the probability of Solana (SOL), Litecoin (LTC), and XRP ETFs gaining approval from the U.S. Securities and Exchange Commission (SEC) to 95% this year.
Bloomberg ETF experts Eric Balchunas and James Seyffart updated their forecast in a post on X on Monday, noting increased optimism for multiple altcoin spot ETFs.
“We expect a wave of new ETFs in the second half of 2025,” Seyffart commented.
The analysts increased their approval odds for Solana, XRP, and Litecoin spot ETFs from 90% to 95%, and assigned the same odds to a potential ETF tracking a basket or index of crypto assets.
According to them, the SEC’s final decision deadline for the individual altcoin ETFs is in October, while approval for a crypto basket ETF could come as early as this week.

More altcoin ETFs to come
The analysts also assigned a 90% probability of approval for several other altcoin spot ETFs, including Dogecoin, Cardano, Polkadot, Hedera, and Avalanche, with final SEC decisions expected in the fourth quarter of the year.
Meanwhile, ETFs proposed by Canary Capital for Sui and Tron were given lower chances of approval—60% and 50%, respectively.
Back in June, Balchunas remarked, “Get ready for a potential altcoin ETF summer,” while Seyffart suggested that “ETFs tracking broad crypto indexes could receive SEC approval as early as next month.”
Solana Staking ETF Set to Launch
Bloomberg reported on Monday that the REX Osprey Solana Staking ETF is scheduled to officially launch on Wednesday, marking the first U.S. ETF to offer crypto staking.
The product initially encountered regulatory pushback from the SEC, which raised concerns after approving its registration. The primary issue centered on whether the ETF met the criteria to be classified as an investment company under existing securities laws.
To secure approval, the issuers agreed to a compromise: at least 40% of the ETF’s assets will be allocated to other exchange-traded products, primarily those based outside the United States.
SEC delays persist
Meanwhile, the SEC continues to hold off on Ethereum staking approvals, delaying its decision on whether the Bitwise spot Ether ETF can include staking as part of its offering.
The agency also postponed its decision on the proposed listing and trading of shares of the Osprey Bitcoin Trust.
