A big number has appeared again in U.S. spot Bitcoin ETFs:

Single-day net inflow of $731 million.

This is the largest single-day inflow since January 14.

Among them, one product, BlackRock's IBIT, alone absorbed about $454 million, accounting for more than 60% of the day's funds.

What is even more noteworthy is the change in资金:

On September 1, it was still a net outflow of about $236 million,
On September 2, it turned into a net inflow of $101 million,
and by September 3, it had surged directly to $731 million.

And for the entire month of August, U.S. BTC ETFs had already جذب about $3.52 billion, compared with only about $172 million in July.

So this time, it cannot simply be understood as “someone suddenly bought BTC in one day.”

Institutional funds really did come back.

But now there is a very important time lag.

This $731 million is data from the U.S. market last night.

At that time, the market was trading:

The Fed may not be in a hurry to raise rates
→ U.S. Treasury yields fall
→ The dollar weakens
→ BTC climbs back above $80,000.

But tonight, the U.S. August nonfarm payrolls unexpectedly came in at +162,000, nearly three times the market expectation of 55,000. Rate-cut expectations cooled again, and U.S. Treasury yields rose accordingly.

So the truly valuable question now becomes:

After the macro environment reverses, will ETFs still keep buying?

BTC is still around $81,000, and has not immediately given back all of last night’s gains after the strong nonfarm payrolls report.

This shows that the $731 million in spot funds at least provided a layer of support for BTC.

There are two scenarios next.

Scenario A: ETFs continue to see significant net inflows

If today and over the next few trading days ETFs continue to see net inflows of hundreds of millions of dollars per day after the strong nonfarm payrolls report, while BTC continues to hold above $80,000, then the nature of the move will change:

That would no longer just be a “rebound from expectations of a Fed pause,” but would look more like institutional funds beginning to reallocate into BTC again.

In this case, the probability of breaking back above $82,000 would rise significantly.

Scenario B: ETFs quickly swing back to outflows

If last night’s $731 million only came in chasing Waller’s dovish signal, and today’s jobs data turns stronger, ETFs could quickly return to outflows,

Then last night’s move was very likely:

A quick rebound driven by macro expectations + ETF flows + short squeeze all at once.

In that case, around $82,000 could instead become short-term resistance.

So $731 million is of course bullish.

But right now, you can’t just see that big number and chase the rally.

What will truly determine whether this rally can continue is whether institutions are still willing to keep buying BTC with real money after the strong nonfarm payrolls report.

As of now, the U.S. market is still open, and the final ETF net flow for September 4 has not yet been fully released.

That makes today’s post-close data especially important.#比特币etf创1月以来最大单日流入
