Crypto ETF Flows in August 2026: Bitcoin Reverses, Solana Surges, and JPMorgan Goes All-In

The week of August 10–15, 2026 delivered a volatile but revealing picture of the US crypto ETF market. Bitcoin ETFs experienced a dramatic reversal from the prior week's inflows, Solana ETFs continued to demonstrate stronger momentum than Ethereum, cumulative Solana inflows crossed a new milestone, and the biggest US bank by assets — JPMorgan Chase — disclosed a significant expansion of its crypto ETF holdings across multiple assets.

Bitcoin ETF Flows: A Mixed Week with a Late Rebound

The week opened with a sharp pullback. After posting their best week since April ($853.5 million in inflows the prior week) , spot Bitcoin ETFs recorded a $144.6 million net outflow on Monday, August 10, led by losses in Grayscale GBTC (‑$52M), BlackRock IBIT (‑$53.6M), and Fidelity FBTC (‑$40.3M) . Outflows continued through midweek — August 12 saw -$70.9 million and August 13 saw -$122.7 million .

However, a late-week rebound emerged. Bitcoin ETFs took in $244.4 million on one day, capping three straight inflow days worth a combined $626 million . For the full August month through the 14th, monthly-to-date Bitcoin ETF inflows stood at approximately +$521.5 million, with 6 inflow days versus 3 outflow days . BlackRock's IBIT alone captured roughly 76% of the three-day total, adding $479 million and lifting its cumulative net inflows to nearly $61 billion .

Solana ETF Performance vs. Ethereum: A Continuing Divergence

Solana ETFs continued to outperform Ethereum ETFs during the week. On August 10, while Bitcoin and Ethereum ETFs bled, Solana ETFs posted +$8.83 million in net inflows — all captured by Bitwise's BSOL fund . On August 12, the divergence continued: Bitcoin ETFs lost $61.1 million while Ethereum funds attracted $7.4 million and Solana funds also drew capital .

Yahoo Finance reported that Solana ETFs lead 2026 crypto ETF growth at 33%, while Ethereum ETFs have posted five months of outflows over the last seven months and their cumulative inflows remain around $1.1 billion — essentially flat since launch . In absolute AUM terms, Ethereum ETFs still command roughly $12 billion vs. Solana's roughly $3.1 billion, but Solana's flow momentum has been consistently stronger throughout 2026 .

Cumulative Solana ETF Inflows Since October 2025 Launch

As of the week of August 10–15, cumulative net inflows across all US spot Solana ETFs (launched October 28, 2025) stood at approximately $1.4 billion to $1.45 billion . Key details:

• BSOL (Bitwise Solana Staking ETF) leads with roughly $900.7 million in cumulative net inflows, capturing about 80% of the category total .
• Total category AUM has reached approximately $3.1 billion, making it the fastest crypto ETF ramp since Bitcoin .
• Solana ETFs have demonstrated unusual resilience, recording zero outflow days through entire months in 2026 even as BTC and ETH ETFs suffered sustained outflows .

JPMorgan Chase Q2 2026 13F Filing: A Strategic Bet on Crypto

JPMorgan Chase filed its Q2 2026 13F with the SEC on August 12–14, revealing significant increases across crypto ETFs :

• Bitcoin (IBIT): ~10.4 million shares of BlackRock's IBIT, valued at roughly $355.7 million — a 25% increase from Q1 .
• Ethereum (ETHA): More than quadrupled its Ether ETF position (a 338% increase) .
• Solana: Opened a new position in the Bitwise Solana Staking ETF (BSOL) — its first disclosed Solana ETF holding .
• XRP: Re-entered XRP exposure through two ETF positions after exiting entirely in Q1 .

Analysts noted that the bank's crypto ETF buying came during a quarter when the broader Bitcoin ETF market saw net outflows, suggesting JPMorgan views these allocations as strategic long-term positions rather than short-term bets .
