US spot bitcoin exchange-traded fund managed by ARK Invest and 21Shares, trading under the ticker ARKB.
US spot Bitcoin ETFs took in about $3 billion between September 17 and 25, enough to push 2026 net flows back above zero. The year's resulting cushion, about $934 million, is under 1% of the roughly $105 billion to $110 billion the funds hold.
Reality
US spot bitcoin ETFs took in about $2.39 billion from September 21 to 25, yet CryptoQuant's 30-day estimate of spot demand was still negative on October 1. Fund subscriptions alone cannot show that the rally has buyers beyond the ETF channel.
Reality
US spot Bitcoin ETFs took in $241.1 million in the week to Oct. 2, about 90% less than a week earlier, Bitfinex analysts said. Their breakout test needs several sessions of at least $340 million each and a daily close above $87,722.
Reality
Bitcoin's spot funds gave back $201.9 million on Friday, four-fifths of it from two sponsors, while ether's kept taking money into a book sitting barely 7% above what its buyers have paid in. That is a thin cushion for a 10-day streak.
