Brian Armstrong Predicts $400,000 Bitcoin Price by 2030. The Forecast Requires 51% Growth Annually: Can It Hold?

Coinbase CEO Brian Armstrong quietly slashed his Bitcoin price target by 60% while keeping his 2030 deadline intact, and the math behind his new number reveals just how narrow the path to getting there actually is.

As of September 19, 2026, Bitcoin (CRYPTO:BTC) is trading at $81,049.99, up 5.11% over the past week and 11.23% over the past month, yet it remains 29.8% lower than a year ago.

During an appearance on CNBC’s Squawk Box Asia on September 10, Coinbase (NASDAQ:COIN | COIN Price Prediction) chief executive Armstrong was asked whether he still expects Bitcoin at $400,000. “I do think that that’s a reasonable target by 2030,” he said. But is that feasible in just over four years?

Armstrong’s Forecast Was $1 Million a Year Ago

Armstrong’s original $1 million target was announced on August 20, 2025, in a post on X citing regulatory clarity, a government Bitcoin reserve and growing interest in crypto exchange-traded products.

The target year has not moved, but the number has fallen 60%. He first mentioned the new range of $300,000 to $400,000 during an appearance on Fox Business Network’s Varney & Co. on August 20, 2026, a year to the day after the million-dollar post, which makes $400,000 the upper end of his expected range rather than a point target.
