Coinbase Lifts Corporate Bitcoin Holdings to 18,000 BTC as Armstrong Touts Collateral Use

Coinbase has increased its corporate Bitcoin holdings to approximately 18,000 BTC, Chief Executive Officer Brian Armstrong said on the company's third-quarter earnings call on October 29, 2026. FinanceFeeds reported that the company had recently purchased its 18,000th Bitcoin. Coinbase is a publicly traded cryptocurrency exchange founded in 2012 and headquartered in San Francisco, according to company records.

Coinbase's Bitcoin Treasury and Quarterly Additions

Coinbase's quarterly regulatory filing disclosed 17,954 BTC held for investment as of September 30, valued at approximately $1.50 billion. Those holdings carried a cost basis of approximately $1.26 billion, an unrealized appreciation of roughly $242 million at the reporting date. The company did not disclose the precise purchase date or transaction price for the latest acquisition.

The treasury expanded through 2026: Coinbase added approximately 1,103 BTC in the first quarter, 819 BTC in the second quarter and 643 BTC in the third, about 2,565 BTC over the first nine months. Coinbase held 15,389 BTC for investment at the end of 2025 and 6,885 BTC at the end of 2024, an increase of approximately 11,069 BTC, or 161%, over the following 21 months. These figures cover Bitcoin owned for corporate investment and exclude customer balances held in custody.

Armstrong described Bitcoin as an increasingly important store of value and financial asset. "Bitcoin-backed lending allows investors to access liquidity without selling their underlying cryptocurrency holdings," he said, pointing to financing products in Coinbase's Base ecosystem. Coinbase reported institutional transaction revenue of approximately $92 million in the third quarter, consumer transaction revenue of $450 million, stablecoin revenue of approximately $307 million and approximately $8.6 billion in cash and cash equivalents.

Coinbase's Regulatory and Product Record

According to akta.pro company records, Coinbase secured a MiCA license from Luxembourg in June 2026, enabling passporting of crypto services across all EU member states. The same records show the company obtained regulatory approval to offer tokenized stocks that month and launched Coinbase for Agents, an AI-agent-integrated trading and payments infrastructure. Coinbase Prime reports $193 billion in safeguarded assets across institutional custody services, and Coinbase Advanced Trade processes $154 billion in quarterly volume traded.

Earlier Coinbase Moves Before the Milestone

On November 2, 2026, New Jersey lifted its order against Coinbase's staking service, allowing residents to resume staking after being blocked since June 2023, Crypto Briefing reported. The pause cost New Jersey users an estimated $15 million in rewards. The same day, Coinbase opened Deribit-powered perpetuals to AI agents, requiring eligible non-US accounts and derivatives onboarding, according to Thedefiant. On October 31, 2026, 1.223 million Solana worth about $117 million was deposited into Coinbase Prime through a single deposit address, TradingView reported.
