Key Insights:
- Crypto ETF issuer activity reflects rising confidence under a pro-crypto U.S. administration and increasing global demand.
- Analysts suggest that approval of even one or two high-probability altcoin ETFs could ignite the next altcoin bull run.
Amid the recent shift in market sentiment, crypto ETFs are once again garnering massive attention from enthusiasts as the odds of approval continue to rise. The growing popularity of these exchange-traded funds comes at a time when the broader crypto market is in a downtrend and struggling to gain momentum.
Bitcoin & Ethereum ETF Inflow Update
Despite the broader bearish market sentiment, blockchain-based transaction tracker Lookonchain reveals a combined weekly inflow of over $2.5 billion into both Bitcoin and Ethereum ETFs, indicating heightened confidence in digital assets despite the prevailing uncertainty.
As of June 30, 2025, total Bitcoin holdings across spot ETFs reached 1,244,285 BTC, equivalent to $133.89 billion.
Data reveals that the top performers in terms of weekly net inflows were the iShares (BlackRock) Bitcoin Trust (IBIT), which added 12,358 BTC; the Fidelity Wise Origin Bitcoin Fund (FBTC), which added 4,755 BTC; and the ARK 21Shares Bitcoin ETF (ARKB), which added 2,502 BTC.
However, not all crypto ETF providers saw inflows. Valkyrie’s BRRR and Grayscale’s GBTC recorded minor outflows, suggesting a selective rotation by investors.
Meanwhile, the Ethereum ETF market is also seeing even stronger momentum in terms of weekly inflows. As of June 30, total ETH holdings stood at 4,082,140 ETH, valued at $10.1 billion. The 7-day net inflow reached 99,660 ETH, roughly $301.49 million, with 5,527 ETH added in the last 24 hours alone.
Spot XRP, SOL, LTC ETF Approval Odds Rise to 95%
Besides Bitcoin and Ethereum ETFs, a Bloomberg crypto ETF expert recently raised the odds of approval for spot XRP, SOL, and LTC ETFs to 95%. The odds for DOGE, ADA, DOT, HBAR, and AVAX filings were raised to 90%. Meanwhile, the odds of ETF approval for SUI, TRX, and PENDLE were increased to 60%, 50%, and 50%, respectively.
Looking at XRP approval odds, a crypto expert recently posted on X (formerly Twitter), stating that a token once sued, ignored, and counted out, XRP, is now knocking on Wall Street’s front door. This sharp rise in approval probability marks a significant moment for altcoin legitimacy in institutional finance.
Spot Altcoin ETF Approvals Could Spark Altseason
Meanwhile, another expert made a bold prediction in a post on X, stating that if even one or two of these high-probability ETFs (XRP, SOL, LTC) receive approval, it could act as the spark that triggers the next altcoin season.
With Bitcoin and Ethereum ETF flows already surging, the market may be on the verge of a broader breakout, this time led by altcoins finally stepping into the ETF spotlight.
Crypto ETF Issuers Leading the Altcoin Push
Data reveals that ETF issuers are not only focusing on BTC and ETH, but, driven by global adoption and a pro-crypto President, they are now actively exploring the altcoin space as well.
Among the leading issuers, Grayscale is aggressively expanding its ETF reach, having filed for XRP, Litecoin (LTC), Solana (SOL), Dogecoin (DOGE), Cardano (ADA), Polkadot (DOT), Avalanche (AVAX), Hedera (HBAR), and broad basket ETFs. Its focus remains on providing broad exposure to top-cap altcoins.
21Shares is also taking a diversified approach, with filings for Solana, XRP, Dogecoin, and Polkadot. The firm is positioning itself to offer both multi-asset ETFs and individual spot altcoin filings.
Meanwhile, Bitwise has filed for XRP, DOGE, SOL, and basket-based ETFs, focusing on smart contract platforms and high-liquidity altcoins. The firm’s filings reflect a strategic preference for assets with active development, strong institutional interest, and long-term utility.
