According to Woofun AI, as of September 4, the weekly net inflow of Solana-related US ETFs experienced a cliff-style decline, falling as high as 97%, in stark contrast to the strong ability of Bitcoin ETFs to attract gold during the same period.
Although data from the Chicago Mercantile Exchange (CME.US) (CME) showed a reduction in net SOL positions, the sharp contraction in ETF side capital inflows revealed a sharp shift in market preferences, and capital allocation is trending significantly towards Bitcoin.
In terms of specific capital flow details, the performance of the Solana ETF showed extreme structural differentiation. According to data compiled by Woofun AI, only the three BSOL, FSOL, and GSOL (GSOL.US) products recorded non-zero net traffic during this statistical period, while VSOL, TSOL, and SOEZ had zero net flow on all trading days, which indicates that the type of product had a decisive influence on the demand situation.
The more critical variable is the comparison of single-day data: on September 4, the Solana ETF recorded a net outflow of $5.2 million, while the Ethereum and Bitcoin ETFs absorbed $25.9 million and $174.6 million respectively.
Although the cumulative net flow of Solana-related ETFs remained positive throughout the week, this small positive balance was mainly offset by inflows from other days rather than continued strong demand. Notably, this data only covers the various ETF products launched by Farside for these three assets, does not cover all cryptocurrency funds, and does not exclude the impact of investors' swap operations between different assets.
Furthermore, since it is not adjusted according to the management scale of different funds, a higher net inflow of dollars does not necessarily mean that demand is stronger compared to the size of the fund. Better data on Bitcoin only shows that the momentum of fund allocation favors BTC, while the new net capital absorbed by Solana and Ethereum is relatively limited.
Judging from the derivatives position structure, changes in CME (CME.US) contracts provide another dimension of perspective. According to the report, SOL's long positions increased by 577 contracts, while short positions were drastically reduced by 1210 contracts. This asymmetric change has led to a decrease in net short positions, but the underlying reason is that the reduction of short positions far exceeds the magnitude of the increase in long positions, rather than simply heating up bullish sentiment.
The more critical variable is that the long and short positions shown in the report do not include assets classified as hedging positions, since such positions cancel each other out when calculating net flow. Therefore, lower net short positions are not entirely due to the fund's active reduction of short exposure, and may also reflect market participants' adjustments in hedging strategies.
This subtle change in derivatives holdings, along with the contraction of capital inflows on the ETF side, forms two sources of current market risk. It suggests that investors need to comprehensively consider the capital flowing into ETF products and changes in derivatives holdings in order to accurately determine whether demand for this asset is expanding.
If you want to prove that there is continued demand for Solana ETFs, the strongest evidence is not a single week's positive balance, but rather multiple weeks of positive performance with more diverse products participating. Comparing these flows to a stable asset base helps to distinguish between a real increase in capital allocation or an apparently higher dollar value simply due to the larger size of the fund. The share creation and redemption situation can provide more details that cannot be shown in net flow data, because trading an existing share on an exchange during the trading period is a different act from creating or redeeming shares through a fund, and a fund may offset capital inflows and outflows, leading to less net flow. The same is true in the derivatives sector: subsequent changes in long and short positions, as well as the impact of options and hedging positions, are factors to watch out for. In this comparison of the three assets, Bitcoin is growing most strongly in terms of ETF fund allocation. Although Solana has also attracted net capital inflows, to prove that demand continues to expand, a positive weekly balance and weak futures position conditions alone are far from enough.
