The 10 US spot bitcoin ETFs collectively shattered their daily net inflow record Tuesday as more than $1 billion of investor assets entered the funds. 

BlackRock’s iShares Bitcoin Trust (IBIT) was again the category standout, notching an all-time high daily inflow total of $849 million, according to BitMEX Research data. 

The Ark 21Shares Bitcoin ETF (ARKB) and the VanEck Bitcoin Trust contributed above-average flows of $93 million and $83 million, respectively.

The boost for VanEck’s product comes after the company said it would waive its 0.20% sponsor fee on the first $1.5 billion of fund assets until March 31, 2025.

Grayscale Investments’ Bitcoin Trust ETF (GBTC), which has bled more than $11.1 billion in assets since converting to an ETF on Jan. 11, saw just $79 million of outflows Tuesday. That outflow total was down from $494 million the day prior.

The $1 billion of net inflows across the 10 bitcoin funds easily surpassed the segment’s previous daily record of $673 million, set on Feb. 28, BitMEX data shows. 

The ETF flow spike came as bitcoin’s price has continued its climb, setting multiple new all-time highs over the past eight days.   

BTC’s price stood at about $73,300 at 7 a.m. ET on Wednesday — up about 15% from a week ago. The asset’s price had risen above $73,600 a few hours prior, marking a new record. 

The assets under management in BlackRock’s IBIT rose above $15 billion at market close Tuesday — behind only GBTC, which has roughly $27.7 billion of assets.

The Fidelity Wise Origin Bitcoin Fund (FBTC) is the group’s third-largest fund, managing about $9.2 billion in assets.  

Tuesday marked the second-best trading volume day for the 10 US spot bitcoin ETFs, according to Bloomberg Intelligence data — as investors traded roughly $8.5 billion worth of the funds’ shares. 

IBIT’s trading volumes on Tuesday represented nearly half of those across the segment, at about $4 billion.

Research

The Solana validator landscape has changed drastically over the past year. The chain now has 1,332 active validators with 380.9 million SOL staked (63.9% of supply) as of February 2025. Validator revenue had diversified beyond inflationary rewards (still making up 55%) to include Jito tips (30%), priority fees (24%), and base fees (<1%), in January, especially with the increased activity on Solana. Since then, issuance has become dominant again (76%), while Jito tips (14%), priority fees (9%), and base fees (less than 1%) have reduced in share of February 2025. There has been a strong shift towards non-inflationary revenue sources, which have become more central to validator economics as priority fees and off-chain blockspace auctions gain traction. Client diversity has also improved drastically, with implementations such as Agave, Jito-Solana, and Frankendancer already in use, and upcoming clients like Firedancer and Sig expected to further strengthen resilience and reduce reliance on a single codebase.
