Peter Brandt Revives $100K Bitcoin Forecast as BTC Tops $80K

Veteran trader and Factor LLC CEO Peter Brandt has revived his well-known Bitcoin logarithmic chart from June 2019, suggesting that BTC’s long-term parabolic trend remains intact as the cryptocurrency trades above $80,000.

Brandt resurfaced the historical forecast as Bitcoin tested resistance around $82,000, drawing renewed attention to a model that originally projected BTC reaching $100,000. When Brandt published the chart in June 2019, Bitcoin was trading near $10,000.

The trader, who has more than four decades of market experience, previously argued that Bitcoin’s cyclical price performance had no close comparison among traditional assets such as gold or major technology stocks. Historical Bitcoin cycles produced extraordinary gains, including advances of roughly 20x, 489x, 42x and 93x, according to the chart.

The logarithmic model is gaining attention again in September 2026 because Bitcoin’s current price structure appears to remain within its long-term ascending channel. BTC is trading relatively close to the lower portion of that historical range, a zone that could indicate a broader accumulation phase if support continues to hold.

One major difference between the current Bitcoin market and the environment Brandt analyzed in 2019 is the growing presence of institutional investors. Earlier Bitcoin rallies were heavily influenced by retail speculation, while the market now benefits from institutional participation and capital flowing through spot Bitcoin exchange-traded funds.

Bitcoin’s substantially larger market capitalization also means repeating the enormous percentage gains of earlier cycles has become increasingly difficult. The diminishing-returns effect makes another 100x rally less realistic, but Brandt’s logarithmic framework suggests the broader bullish trajectory could remain intact.

The $100,000 Bitcoin target therefore remains an important psychological milestone as traders watch whether BTC can break through the $82,000 resistance area and maintain its long-term support structure.

Bitcoin’s path toward new record highs is unlikely to move in a straight line. However, Brandt’s revived chart suggests that as long as the lower boundary of the historical trend channel holds, BTC’s multi-year bullish structure and parabolic outlook remain technically valid.
