SOL spot ETFs net $3.78M inflows

U.S.-listed spot Solana exchange-traded funds drew $3.78 million of net inflows on May 19, according to market trackers that publish daily fund-by-fund flow data. Fidelity’s FSOL accounted for most of the move, with $3.2 million of the total, while VanEck’s VSOL added about $0.6 million and other listed products were unchanged. The figure circulated on X in a May 21 post by user 0xzxcom, but the underlying numbers also appeared on public ETF flow dashboards. The May 19 result was modest in dollar terms next to bitcoin and ether ETF swings, but it extended a run of positive days for the newer Solana products. Farside Investors’ table shows U.S. spot Solana ETFs recorded inflows on May 18, May 19 and May 21, with no net flow on May 20. Trading Digits’ dashboard separately listed the May 19 total at $3.8 million, matching the rounded figure in the social post. ### Which fund brought in most of the money? (farside.co.uk) Fidelity’s FSOL was the main contributor on May 19. Farside’s table showed FSOL taking in $3.2 million that day, compared with $0.6 million for VanEck’s VSOL and zero for Bitwise’s BSOL, Franklin’s SOEZ, 21Shares’ TSOL and Grayscale’s GSOL. SoSoValue’s U.S. Solana ETF dashboard also showed FSOL as one of the larger products in the category by assets. Its page listed FSOL with about $161.11 million of cumulative net inflows and roughly $115.06 million in net assets, while Bitwise’s BSOL remained the largest fund on that screen by market value. (farside.co.uk) ### How big is the Solana ETF market now? CoinGlass put total Solana ETF market capitalization at about $883.65 million as of its May 21 update, with total trading volume of $50.42 million across the products it tracks. (farside.co.uk) On that dashboard, BSOL had the largest market cap at about $642.51 million, followed by FSOL at $113.15 million and GSOL at $108.89 million. Farside’s cumulative flow table showed $1.12 billion of aggregate inflows into the U.S. (sosovalue.com) Solana ETF group since launch, though that total includes seed capital and early product-specific moves noted in the table. The same page listed cumulative flows of $903.7 million for BSOL and $181.5 million for FSOL, with TSOL still negative on a cumulative basis. ### Why was a mortgage-rate number in the same social post? The May 21 X post paired the Solana ETF flow figure with a reference to 30-year U.S. mortgage rates at 6.75%. (coinglass.com) That mortgage number appears to have been part of a broader market roundup rather than a direct link to Solana fund flows. Public mortgage trackers published somewhat different daily readings around the same date, reflecting differences in methodology and timing. (farside.co.uk) Freddie Mac’s weekly Primary Mortgage Market Survey, a widely followed benchmark, most recently showed the average 30-year fixed-rate mortgage at 6.23% for the week ending April 23, 2026, on the version surfaced in search results. Daily consumer-facing trackers for May 21 showed higher readings, including 6.72% from Forbes Advisor’s cited source and 6.58% from Mortgage Daily. ### Did flows keep coming after May 19? (forbes.com) Farside’s table showed another net inflow day on May 21. Its page listed $3.9 million of inflows on May 21, all attributed to FSOL, after a flat reading on May 20. CoinGlass, which reports flows in SOL units as well as fund market data, also showed a positive May 21 reading led by FSOL. Daily flow tables on both services remain public and are where market participants can track the next session’s updates for FSOL, BSOL, VSOL, TSOL, SOEZ and GSOL.
