Ark Invest has bought more of its spot bitcoin ETF as it continues to dump shares of the largest bitcoin futures fund. 

The fund manager’s Ark Next Generation ETF (ARKW) on Thursday bought 365,695 shares of the spot bitcoin ETF it launched last week with 21Shares, according to a trade notification.  It sold 758,915 shares of the ProShares Bitcoin Strategy (BITO) from the fund that day. 

The move comes after ARKW sold 757,664 of BITO shares on Tuesday, while adding 365,427 shares of the Ark 21Shares Bitcoin ETF (ARKB). 

In total, the roughly 730,000 of ARKB shares added — as well as the 1.5 million of BITO shares sold — were each worth roughly $30 million at 10 am ET on Friday morning.

The ProShares fund was the first bitcoin futures ETF in the US. It launched in October 2021 and gained more than $1 billion in assets after two days on the market. 

But 10 US spot bitcoin ETFs launched last week following a milestone decision by the US Securities and Exchange Commission — opening up a new access point for BTC exposure.

Bloomberg Intelligence analysts predicted last month Ark Invest would offload its position in the Grayscale Bitcoin Trust (GBTC) and ultimately move that capital into ARKB to bolster the fund’s asset base. Flows and volumes are “crucial” to marketing an ETF, they noted at the time. 

Ark Invest did just that, first replacing sold shares of GBTC with BITO before piling money into their own spot bitcoin ETF.

Kinetiq has established itself as Hyperliquid's dominant liquid staking protocol, holding 82.5% of LST market share with $610M in TVL. The protocol is now expanding beyond its kHYPE staking core into higher take-rate verticals: iHYPE for institutional custody rails, Launch for HIP-3 capital formation, and Markets for builder-deployed perpetuals. We view Markets, launching Jan. 12, as the highest-potential product line given its mechanically scalable, activity-linked unit economics. Near-term revenue remains anchored by kHYPE's KIP-2 fee schedule (~$1.6M annualized), while Markets provides embedded optionality if HIP-3 economics normalize post-Growth Mode. KNTQ's setup is relatively clean: zero insider unlocks until November 2026, 6.2% buyback yield from staking revenue, and cleared airdrop overhang. Risks center on unproven Markets execution, declining kHYPE TVL despite ongoing incentives, and competition from Hyperliquid's native initiatives.
