Coinbase CEO Brian Armstrong Reaffirms $400,000 Bitcoin Price Target by 2030
Coinbase Chief Executive Officer Brian Armstrong reaffirmed his prediction that Bitcoin will reach $400,000 by 2030 during an interview on September 28, on Nicole Lapin’s podcast Money Rehab, building his target on historical four-year halving cycles and institutional adoption while acknowledging the forecast is a personal hypothesis rather than an official company position.
Brian Armstrong Retains the 2030 Target Amid Market Swings
The target requires a compound annual growth rate of 51% over a little more than four years, starting from a base near the mid-$80,000 range. This pace outpaces Bitcoin’s historical compound annual growth rate of roughly 34% over the preceding nine years. If the cryptocurrency grew at its historical average instead, it would land near $250,000 by 2030. Armstrong originally floated a $1 million target in August 2025 before revising the range to $300,000 to $400,000 during an appearance on Fox Business Network’s Varney & Co. on August 20, 2026.
The $400,000 valuation would imply a fully diluted valuation approaching $8.4 trillion based on the maximum supply of 21 million coins, or about $8 trillion based on roughly 20 million circulating coins. During his September 19 interview, Armstrong emphasized that past performance cannot guarantee future prices and warned against claims of certainty. Armstrong’s projection assumes Bitcoin will reach roughly three times its previous all-time high of $126,000 recorded in October 2025.
Halving Cycles Face New Market Dynamics and Disputing Voices
The core of Armstrong’s thesis rests on the four-year supply schedule, where every 210,000 blocks the reward paid to miners is cut in half. The halving in April 2024 reduced block subsidies to 3.125 BTC, with the next scheduled at block 1,050,000 in the spring of 2028, which will lower daily issuance below 230 bitcoins. Historical contractions of new supply have preceded price expansions followed by a roughly one-year correction period.
This traditional framework faces skepticism from other market participants. Matt Hougan, chief investment officer at Bitwise, argued that the four-year cycle model is losing relevance due to spot exchange-traded funds and corporate treasury demand. Daily issuance hovers near 450 bitcoins, while U.S. spot Bitcoin ETFs hold over one million coins, absorbing daily supply shocks. U.S. spot Bitcoin ETFs recorded $2.4 billion in net inflows during the week ending September 25, bringing total net assets to about $108.4 billion.
Diverging Long-Term Forecasts Across the Digital Asset Sector
Alternative institutional models project vastly different trajectories for the asset class by the end of the decade. Cathie Wood at ARK Invest maintains a bull case target of $1.5 million for Bitcoin by 2030, with a baseline target hovering around $710,000. These figures sit alongside corporate accumulation strategies such as those executed by Strategy under Michael Saylor, who has pointed to long-term horizons stretching toward 2046.
Polymarket assigned 64% odds that Bitcoin will touch $85,000 by the close of 2026, serving as an immediate checkpoint for whether the 51% annual pace required for Armstrong’s target remains on track.
