According to data from SoSoValue, SOL spot exchange-traded funds recorded a single-day total net outflow of $12.7429 million on June 3 (US Eastern Time). The move was primarily driven by two major products, signaling a shift in near-term sentiment toward the Solana asset. The outflow figure stood out against a backdrop of generally steady inflows in the broader crypto ETF space.
Breakdown of Major ETF Outflows
The Bitwise Solana Staking ETF (BSOL) saw the largest outflow, with $11.5573 million exiting the fund on the day. Despite this, its historical total net inflow since launch remains a substantial $894 million, underscoring the size of the product. The Grayscale Solana Trust (GSOL) lost $1.1856 million, bringing its lifetime net inflow to $115 million. Together, these two funds accounted for essentially the entire daily net outflow, while other SOL ETFs saw only marginal net movements.
In terms of asset scale and absolute outflow, Bitwise's product occupies a dominant position among SOL ETFs, with its single-day outflow roughly ten times that of GSOL. This illustrates the ongoing rebalancing of capital among different fund structures. Despite the noticeable daily drain, the cumulative historical flows of both products indicate substantial net subscriptions since their respective launches.
Aggregate Metrics and Market Standing
As of the reporting time, the total net asset value of all SOL spot ETFs stood at $827 million, with SOL representing a net asset ratio of approximately 2.01%. On a longer horizon, the cumulative historical net inflow across all SOL spot ETFs has reached $1.127 billion, reflecting a sustained net positive flow since product inception. The June 3 outflow thus appears more as a short-term fluctuation rather than a change in the broader accumulation trend.
The competitive landscape for SOL spot ETFs is taking shape, with Bitwise and Grayscale emerging as key players offering different structural exposures. As more institutional participants may enter this segment, daily fund flow swings are likely to become a regular feature. For investors tracking SOL exposure, daily ETF flow data provides a useful sentiment gauge, though it should ideally be assessed alongside longer-term positioning data and on-chain indicators to gain a more complete picture.
