Bitcoin ETFs also logged strong inflows, with $522 million added across the 12 products.
US-listed Bitcoin and Ethereum spot exchange-traded funds drew more than $1 billion in net inflows on Monday, reversing recent outflow trends and boosting optimism across crypto markets.
The move came as Bitcoin prices rebounded sharply above $114,000, supported by seasonal factors and renewed accumulation by large holders.
Ethereum spot ETFs, which had seen five consecutive sessions of outflows, flipped positive with $547 million in net inflows, according to SoSoValue.
Fidelity’s Ethereum Fund (FETH) led the gains, drawing $202 million in a single day, followed by BlackRock’s iShares Ethereum Trust (ETHA) at $154 million.
The nine Ethereum ETF products now collectively manage $27.5 billion in assets, equivalent to about 5.4 percent of Ethereum’s circulating market cap.
The turnaround underscores renewed institutional appetite after a weak September.
Bitcoin ETFs also logged strong inflows, with $518 million added across the ETFs.
Fidelity’s FBTC drew the largest daily inflow of $299 million, while ARK 21Shares Bitcoin ETF (ARKB) followed with $62 million.
Most other funds saw net gains, though BlackRock’s iShares Bitcoin Trust (IBIT) posted a modest $46.6 million outflow.
Collectively, Bitcoin ETFs now hold $150 billion in assets under management, representing about 6.6 percent of the cryptocurrency’s total market cap.
Bitcoin extended its recovery into Tuesday, climbing as high as $114,776 in the past 24 hours before easing slightly below $114,000.
The rebound follows a sharp drop below $109,000 last week amid heavy liquidations and quarterly options expiry, which amplified selling pressure.
Market participants pointed to “Uptober” seasonality — October’s historical trend of 20 percent average gains — as a factor lifting sentiment.
On-chain data showing fresh accumulation by so-called whales also supported the move.
Despite renewed momentum in crypto, broader sentiment remained cautious as investors monitored political developments in Washington.
US lawmakers face a Tuesday midnight deadline to strike a funding deal and avert a government shutdown.
Without an agreement, the closure would begin on Wednesday, coinciding with new US tariffs on heavy trucks, pharmaceuticals, and other goods.
Analysts at Bank of America warned that a prolonged shutdown could complicate Federal Reserve policy-making ahead of its October 29 meeting by delaying critical economic data releases, including the September payrolls report.
“If the shutdown lasts beyond the Fed meeting, the Fed will rely on private data for its policy decisions. On the margin, we think this may lower the likelihood of an October cut, but only marginally,” the bank noted.
