Key Highlights

  • Bitcoin (BTC) gained about 9% in September to an eight-month high above 85,000, setting up the Uptober test.
  • Historically October was positive in about 10 of the last 13 years, or 77%; 2017 to 2025 saw 7 of 9 positive with a median gain of 10.9%.
  • October 2025 ended about 4.0% lower, the first negative October since 2018; Q4 was positive in only 5 of 9 years, median 5.4%.
  • XRP was positive in only 3 of 9 Octobers (33%, our calculation); these are historical figures, not guarantees.

What history shows

Bitcoin has risen in October in roughly 10 of the last 13 years, a 77% hit rate, and in 7 of 9 years from 2017 to 2025 with a median gain of 10.9%. These are historical statistics and offer no guarantee of future results. A small sample of 13 observations is easily distorted by a few large moves, and the median can mask wide dispersion. October 2025 ended about 4.0% lower, the first negative October since 2018, showing that the pattern can fail. Seasonality is best viewed as a mild tendency rather than a rule that investors can rely on.

Context: September and the wider quarter

The setup is helped by September's gain of about 9% and an eight-month high above 85,000, yet Bitcoin has so far failed to hold above 87,000. The fourth quarter is less consistent than October alone: it was positive in only 5 of 9 years, about 56% (our calculation), with a median of 5.4%. XRP has been weaker still, positive in 3 of 9 Octobers. Past patterns come from different eras, with different participants, so they may not map onto today's market with spot funds such as iShares Bitcoin Trust ETF (NASDAQ:IBIT) as a major source of demand.

Why flows, rates and jobs matter more now

With ETFs now a large source of demand, daily flows into products such as iShares Bitcoin Trust ETF (NASDAQ:IBIT) can outweigh the calendar. Bitcoin ETF net Assets are near USD 109.3 billion, and recent flows have cooled from late September's strong week. Rates matter too: weak payrolls of 29,000 on Oct 2 eased hike bets and prompted a spike toward 87,230. If macro data surprise, seasonality can be overwhelmed, as October 2025 showed. Investors should treat Uptober as context and weigh iShares Bitcoin Trust ETF (NASDAQ:IBIT) flows, rates and risk appetite.

Where Things Stand

October's 77% historical win rate is a useful reference but not a reliable edge. A 13-year sample, a negative October in 2025 and only 5 positive fourth quarters in 9 years all argue for caution. This year's 9% September gain and an eight-month high above 85,000 help, yet flows, rates and jobs data now carry more weight than the calendar. Anyone using iShares Bitcoin Trust ETF (NASDAQ:IBIT) or other exposure should remember that history is no guarantee.
