Bitcoin traded near $83,100 on September 30 as the month closed roughly 5 to 6 percent above the early-September range near $78,500. GuruFocus printed $83,109 for the date. Coinbase’s prior daily close, via FRED, was $83,636.70 on September 29.

U.S. spot Bitcoin exchange-traded funds recorded a $66.2 million net inflow on September 29, according to daily trackers that compile issuer creations and redemptions. BlackRock’s IBIT added about $51.1 million. ARK 21Shares’ ARKB added $33.2 million. Bitwise’s BITB offset part of that with an $18.1 million outflow.

The Tuesday print extended the inflow run to nine consecutive sessions. Monday’s figure had been $31.1 million. Combined, the two sessions added just under $100 million after the $2.4 billion week that ended September 25. Cumulative net flows since January 2024 remain near $57.6 billion, with fund net assets around $108 billion on the same boards.

Key takeaways

What a $66.2 million ninth-day print means into October

The late-September pace is a step down from the $999 million day on September 21, but the streak itself is the longest of the month. Price did not reclaim the $86,000–$87,000 highs from September 21–23. Year-over-year the token is still about 27 percent below the September 2025 area near $114,000.

Primary sources for this snapshot are the Coinbase Bitcoin series on FRED, exchange aggregates compiled on September 30, and the daily U.S. spot tables summarized by TFTC’s flow tracker. The next confirmed issuer print covers the September 30 cash session.

What to watch next

October opens against a cost-basis cluster that several on-chain desks have placed between $84,000 and $85,000. Whether the nine-day inflow run survives the first full week of the new month will be visible in the same creation and redemption tape.
