Solana ETFs Experience 12 Consecutive Weeks of Inflows, While Bitcoin Has Its Quietest Week on Record

Solana ETFs held their ground through a Fed rate hike and a failed Senate crypto bill, while Bitcoin funds swung nearly $1.5 billion in a single week just to end up almost exactly where they started.

Solana (CRYPTO:SOL) spot ETFs recorded an additional $13.2 million in inflows during the week ending September 18, 2026, according to SoSoValue. In contrast, Bitcoin (CRYPTO:BTC) spot ETFs netted only $6.2 million over the same period, reflecting the smallest weekly inflow figure in the funds’ 141 weeks of trading.

The 141-week timeline includes every week since Bitcoin spot ETFs launched on January 11, 2024. Notably, the week with the fewest Bitcoin inflows coincided with Solana’s ongoing streak of inflows.

Solana ETFs Recorded Inflows on Days Bitcoin ETFs Sold

Throughout the week, Solana’s daily inflows were modest but consistent, with no negative sessions. On September 14, Solana gained $11.01 million. On September 15, it added $1.35 million, and on September 16 it took in $836,926. September 17 closed with no change.

The context of these inflows is significant because two of those days could have ended Solana’s streak. On September 15, the Senate rejected the CLARITY Act by a narrow margin of 49 to 50 votes, a bill that would have clarified how US regulators handle digital assets. The following day, the Federal Reserve raised its target range by 25 basis points to an upper bound of 3.75% to 4.00%.
