Wall Street's Bitcoin ETF trade is getting a stress test. Investors pulled more than $1 billion from U.S.-listed spot Bitcoin funds in just two trading sessions, according to Bloomberg, as midterm election uncertainty and a major crypto security breach rattled sentiment.

The numbers are stark: roughly $1.04 billion in combined net outflows on Oct. 30 and Nov. 2. BlackRock's iShares Bitcoin Trust (IBIT) shouldered $405 million of Monday's withdrawals alone.

The Exodus Was Widespread on Oct. 30

The Oct. 30 selloff hit major Bitcoin ETFs across the board. Data from Farside Investors shows IBIT lost $233.7 million, while Fidelity's Wise Origin Bitcoin Fund (FBTC) recorded $201 million in outflows.

ARK 21Shares Bitcoin ETF (ARKB) shed another $129.5 million, and Bitwise Bitcoin ETF (BITB) saw withdrawals of $25.7 million.

Monday's activity, however, showed some divergence. While IBIT suffered $405 million in withdrawals, FBTC attracted approximately $6.7 million in fresh capital. So investors aren't abandoning every Bitcoin vehicle uniformly. Some are clearly shopping around, or perhaps just rebalancing.

Midterms Could Reshape the Crypto Rulebook

The political backdrop adds another layer of uncertainty. President Donald Trump's crypto-friendly agenda, including his proposed Strategic Bitcoin Reserve and the GENIUS Act, helped create a more supportive regulatory environment for digital assets.

But the industry's next big legislative priority, the CLARITY Act, failed to advance in the Senate in September. A shift in congressional control after the midterms could complicate efforts to revive the bill and potentially increase regulatory scrutiny of crypto.

A Democratic sweep of both chambers could redirect attention toward tighter oversight, potentially slowing the push for clearer market-structure rules. Any delay in establishing a comprehensive framework could have implications beyond Bitcoin prices. Institutional investors and financial advisers seeking regulatory clarity before expanding digital-asset allocations may remain cautious, potentially limiting fresh demand for spot Bitcoin products like IBIT, FBTC and ARKB.

A Democratic-controlled Congress could also increase scrutiny of crypto exchanges, custodians and stablecoin issuers, adding another layer of uncertainty for the ecosystem supporting these funds. However, existing spot Bitcoin ETP approvals would not automatically be reversed by a change in congressional control.

Binance Hack and Derivatives Selling Add Pressure

Politics isn't the only weight on Bitcoin. The Oct. 29 Binance hack, which the exchange attributed to North Korean hackers, has raised concerns about crypto-market security.

Bitcoin was trading near $77,000 on Tuesday, struggling to establish support after its latest decline.

Derivatives positioning also points to caution. According to CoinMarketCap research head Alice Liu, Bitcoin futures recorded $2.7 billion in net aggressive selling over seven sessions, even as spot markets registered net buying.

For Bitcoin ETF investors, that distinction matters. The divergence suggests leveraged traders are reducing exposure even as spot-market participants continue accumulating Bitcoin.

Whether the latest ETF withdrawals represent election-related hedging, security-driven risk reduction or broader profit-taking remains unclear. But fund flows in the sessions following the election could offer a better indication of whether institutional investors are stepping away from Bitcoin or simply waiting for political and market uncertainty to subside.
