U.S. Solana ETFs Log Positive Inflows Every July Trading Day as TSOL Moves to FTSE Benchmark

Every U.S. trading session in July has closed with net inflows into Solana SOL$77.110.0% spot ETFs, a streak that has run while SOL trades approximately 57% below where it was priced when those funds launched last October, per CoinGlass data. Alongside that flow picture, 21Shares filed an 8-K with the SEC on July 7 disclosing that its TSOL fund will shift from a CF Benchmarks reference rate to the FTSE Digital Assets Index for daily pricing and NAV calculation, effective August 24, 2026.

The two developments together mark a distinct moment in the first year of U.S. Solana ETF trading: consistent demand persisting through a steep price drawdown, and the benchmarking infrastructure that underlies these products undergoing its own structural upgrade.

$5.75 Million Net Inflows in the First Week of July

The first full trading week of July produced $5.75 million in net inflows across U.S. spot Solana ETFs, according to data from CoinGlass. On July 6, daily net inflows reached 103,020 SOL across the active products: 21Shares TSOL, Bitwise BSOL, Grayscale GSOL, and Fidelity FSOL.

Bitcoin spot ETFs registered $527 million in net outflows over the same week, extending an eight-week outflow stretch, per CryptoBriefing's July 7 reporting. Ethereum funds shed $13.67 million net. XRP ETFs drew $17.19 million in inflows. Solana was the only major category where every session closed positive.

May 2026 produced $115 million in monthly net inflows, the strongest single month since the October 28, 2025 launch. That total was driven by individual high-volume sessions. July's character is different: a clean positive streak rather than headline days, sustained through a period when Bitcoin and Ethereum ETF categories have faced persistent redemptions.

More Than $1 Billion in Net Inflows Since the October 2025 ETF Launch

U.S. spot Solana ETFs have accumulated more than $1 billion in cumulative net inflows since their launch on October 28, 2025, per data tracked by SoSoValue. Over that same period, SOL has declined approximately 57% from its October 2025 launch-period price, per CoinGlass.

That divergence (sustained inflows against a falling underlying price) has run counter to the outflow patterns that typically emerge in retail-driven ETF categories when the underlying asset declines sharply over several months.

The category has generated a string of institutional-side signals since launch. Dartmouth's endowment disclosed a $3.3 million BSOL position in June. Grayscale cut GSOL's annual sponsor fee to 0.19% last month, its lowest since launch. The July inflow streak adds to that body of evidence.

21Shares TSOL Files to Swap CF Benchmarks for FTSE Digital Assets Index

In its 8-K filing dated July 7, 21Shares disclosed that TSOL will terminate its existing data licensing agreement with CF Benchmarks (the provider of the CME CF Solana-Dollar Reference Rate New York Variant) and enter a new agreement with FTSE International Limited.

The FTSE license covers daily valuation and NAV calculation under an initial one-year term with automatic annual renewals. It takes effect August 24, 2026; the CF Benchmarks agreement ends August 31.

21Shares filed equivalent 8-Ks for its Ethereum and XRP ETFs on the same day, each naming FTSE as the incoming benchmark provider. The coordinated move reflects the entry of a second institutional-grade index provider into U.S. crypto ETF benchmarking, expanding beyond CF Benchmarks, which has been the dominant reference rate for most digital-asset ETFs since the first Bitcoin products launched in 2024.

Both the FTSE Digital Assets Index and the CF Benchmarks rate reference the same underlying SOL market, so the transition does not change the fund's exposure or how SOL's price is reflected in NAV. For institutional investors and their compliance teams, the significance is structural: FTSE is a globally recognized index brand with established governance frameworks that sit within existing vendor-approval processes at large asset managers and pension funds. The addition of a second credible provider also reduces concentration risk in the benchmarking layer of the U.S. crypto ETF stack.

Whether the benchmark switch will affect TSOL's flows directly is an open question. What the filing confirms is that the administrative infrastructure supporting Solana ETFs (pricing governance, fee structures, authorized participant agreements) is being built out with the same attention to institutional standards that the products have applied since launch.
