Institutional ETF Flows Favor Altcoins Over Bitcoin

On June 15, spot Bitcoin exchange-traded funds recorded a $64.09 million net outflow. Spot Ether ETFs recorded $22.50 million in inflows, HYPE products added $17.19 million, XRP funds took in $2.82 million and Solana ETFs added $2.81 million, according to aggregated flow data.

Market-structure data for the June 10–16 window show Bitcoin’s share of the total crypto market slid from 56.79% to 56.06%. Ether’s share moved from 9.11% to 8.82%, stablecoins fell from 12.87% to 11.98%, and the category covering all other tokens rose from 21.23% to 23.14%.

Spot HYPE ETFs have attracted about $153 million in net inflows and nearly $900 million in trading volume since their launch roughly a month ago. Three products-21Shares’ THYP, Bitwise’s BHYP and Grayscale’s HYPG-hold HYPE directly and pass staking rewards to investors. Recent estimates show roughly 434 million HYPE, or about 45% of the stakeable supply, was staked.

Hyperliquid’s HIP-3 framework enables perpetual futures on commodities, forex, equities and pre-IPO private companies. The SPCX contract, a SpaceX pre-IPO perpetual listed in May, registered aggregate open interest above $215 million and served as a venue for pre-listing price discovery before SpaceX began trading on June 12. Grayscale’s research noted HIP-3 markets reached about $3.2 billion in peak open interest in June and reported more than $200 billion in cumulative trading volume since launch. Grayscale described the platform model as one in which the HYPE token captures trading fees.

Geoff Kendrick, global head of digital assets at Standard Chartered, reported anecdotal evidence that some Bitcoin ETF holders sold to raise cash for the SpaceX initial public offering and expects that selling pressure to ease now that the IPO has started trading.

Tim Sun, senior researcher at HashKey Group, noted the reopening of the Strait of Hormuz eased market fears and could provide temporary relief for risk assets including Bitcoin. He cautioned that a sustained reversal would require renewed consistent spot buying and a return of ETF capital inflows.

The June 15 flows and the June 10–16 market-structure changes leave open whether institutional allocation is shifting from Bitcoin into a broader set of tokens or reflecting short-term liquidity needs tied to the IPO.
