Social posts show Solana ETFs drawing inflows while Bitcoin and Ethereum funds see outflows

Social posts on X on May 21 and May 22 pointed to a split in crypto exchange-traded fund flows: Solana products were still taking in money while Bitcoin and Ethereum funds were losing it. The posts circulated screenshots from third-party trackers rather than issuer statements, but the direction matched published data from CoinGlass and Farside Investors. CoinGlass showed Solana ETF net flows at plus $3.9 million for May 21, against Bitcoin net outflows of $100.9 million and Ethereum net outflows of $32.6 million. ### Which data points were people on X actually sharing? A May 21 X post cited Solana ETF inflows alongside Bitcoin and Ethereum outflows and linked the move to broader altcoin interest, according to the social briefing provided for this story. The post also referenced NIL, a token tied to Nillion, as part of the same retail trading conversation. CoinGlass's crypto ETF market page listed the latest trading day it had updated as May 20, and showed aggregate net flows of minus $100.9 million for Bitcoin ETFs, minus $32.6 million for Ethereum ETFs and plus $3.9 million for Solana ETFs. (coinglass.com) The same page named Fidelity's FSOL as the top Solana ETF by daily net inflow at $3.9 million. ### How strong were Solana ETF inflows on their own? Farside Investors' Solana ETF table showed $3.9 million of net inflows on May 21, all attributed to FSOL, with no flows recorded that day for BSOL, VSOL, TSOL, SOEZ or GSOL. Farside's table also showed Solana funds recorded positive net flows on May 19 and May 18, after a flat reading on May 20. CoinGlass's Solana-specific tracker showed the same May 21 direction, though in token terms rather than dollars. (coinglass.com) Its page listed total Solana spot ETF net inflow of 45.29K SOL for May 21, with the entire day's net addition assigned to FSOL. ### Were Bitcoin and Ethereum outflows large by comparison? CoinGlass showed the gap was wide. Its market overview page put Bitcoin ETF net outflows at $100.9 million and Ethereum ETF net outflows at $32.6 million on the latest trading day shown, compared with Solana's $3.9 million inflow. (farside.co.uk) The same CoinGlass page also said total crypto ETF net flows across tracked products were negative $104.6 million for that session. (coinglass.com) BlackRock's IBIT was listed as the biggest single Bitcoin ETF drag with a daily outflow of $103.7 million, while ETHA was shown with a $38 million outflow on the Ethereum side. ### What about the NIL move that showed up in the same posts? Nillion's NIL token was part of the same social-media burst, but live market trackers did not confirm the more-than-33% 24-hour gain cited in the post at the time of checking. (coinglass.com) CoinGecko showed NIL down 11.36% over 24 hours, while CoinGlass showed it up about 9% and CoinCodex showed an 11% gain, underscoring how intraday snapshots and platform timing can diverge. CoinGecko valued NIL at about $27.1 million in market capitalization with roughly $20 million in 24-hour trading volume. CoinGlass put open interest near $19.1 million and spot volume near $26.9 million. ### What should readers watch next in this flow story? May 22 is the next date to watch because trackers such as Farside Investors and CoinGlass update daily flow tables as new ETF-session data comes in. (coingecko.com) The next confirmation point for the X narrative is whether Solana funds, including Fidelity's FSOL, extend inflows while Bitcoin and Ethereum products remain in outflow territory.
