Bitcoin nears $87,177 high as weekly ETF inflows shrink 96%
Bitcoin came within $650 of its $87,177 Friday high on Sunday while weekly US spot ETF inflows fell to about $83 million from $2.39 billion. October's seasonal record now has to carry a rally that fund money is backing at a fraction of September's pace.

- Bitcoin has closed higher in 10 of the past 13 Octobers with a median gain of 12.7%, though October 2025 finished down 3.7%.
- CPI data arrives Oct. 14 and the Federal Reserve meets Oct. 27-28, while turbulence around the Strait of Hormuz keeps oil and inflation expectations in play.

Why it matters
- constraint At about $83 million a week, US spot ETF buying would need roughly 35 weeks to absorb a Mt Gox distribution worth about $2.9 billion.
- decision Anyone sizing a trade on the seasonal median is betting on a further 8.8% from Sunday's price, to about $94,200.
- exposure A daily close below $82,000 would put $78,000 to $80,000 back in range, up to about 10% under Sunday's price.
The $134.4 million that opened October [6] fell inside a week that netted only about $83 million on provisional data [8]. If both numbers hold, the other days of the Sept. 28 to Oct. 2 window had net outflows of roughly $51 million [2]. The week before brought in $2.39 billion [8]. That is about 89% of the roughly $2.7 billion the funds collected in all of September [7][3]. Daily ETF trading value has since dropped by more than half, from $4.57 billion on Sept. 21 to below $2 billion [9][9].
At Sunday evening's $86,536 [2], the October opening inflow bought about 1,550 bitcoin [4]. The Mt Gox wallets have 34,388 BTC left in them, about $2.9 billion worth, with a creditor deadline of Oct. 31 [13]. The holding is about 22 times the opening inflow in coins [5], and in dollars it is larger than everything the funds took in during September [10]. The trustee has extended the deadline before [13]. If the coins do move, they will meet institutional buyers who, in Bitcoin.com News's description, have not left but "aren't going for broke at current prices" [15].
On the levels the same report maps, the price has three paths. A daily close above $87,500 to $88,000 would open $90,000 and eventually $95,000 to $96,000 [10]. A stall under Friday's $87,177 high, in a zone sellers have defended repeatedly [3], points back to first support at $84,000 to $84,300, with the structural floor at $82,000 to $82,500 [11]. The third path is that the macro calendar or a Mt Gox distribution moves the price before the chart settles anything [12][13].
I think October's seasonal record is carrying more of this move than fund money is. Bitcoin is up about 3.6% from its September close [7], while weekly ETF buying runs at roughly 3.5% of the prior week's pace [1]. The counter-case has its own numbers. The gap to Friday's high is $641, under 0.8% [6], and one session can close it. A fund complex that took in about $6.3 billion in the third quarter [7] has slowed its buying, but it still finished the latest week positive [8]. Prediction markets lean cautious: Polymarket gives about a 39% chance of $100,000 before 2027, and Kalshi's year-end pricing sits close to where bitcoin trades now [14].
Two outcomes would prove this view wrong. If bitcoin closes a day above $88,000 while weekly flows stay near $83 million, the level will have broken without the institutional bid. If weekly inflows climb back above $1 billion within the next two weeks, the rally has fund buying behind it again, and the seasonal case stops being the main support for the price.
What to watch
- Whether the Mt Gox trustee extends the Oct. 31 creditor deadline again or starts moving the 34,388 BTC.
- Final figures for the Sept. 28 to Oct. 2 ETF week: a revision away from $83 million changes the implied $51 million of outflows on the other days of that week.
