Coinbase’s Third-Quarter Filing Shows Crypto Activity Expanding Beyond Spot Trading

Coinbase Global reported stronger third-quarter results on October 30, 2025, offering a regulated-company view of how renewed trading activity, stablecoin balances and derivatives expansion were reshaping the cryptocurrency business.

The company’s Form 10-Q and shareholder letter covered the three months ended September 30, 2025. Coinbase reported $1.87 billion in total revenue, conventionally rounded to $1.9 billion, and $432.6 million in net income. Net income attributable to common stockholders translated to diluted earnings of $1.50 per share. A year earlier, Coinbase had reported $75.5 million in net income and diluted earnings of $0.28 per share.

Those figures mattered because Coinbase was no longer presenting only a simple wager on retail spot-market enthusiasm. Its disclosures showed transaction revenue recovering while stablecoin, custody and derivatives operations supplied additional institutional exposure to digital assets.

Trading activity returns

Transaction revenue reached $1.05 billion, compared with $572.5 million in the third quarter of 2024. Coinbase defined trading volume as the dollar-equivalent value of matched spot trades between buyers and sellers on its platform during the measurement period. On that basis, third-quarter volume totaled $295 billion: $59 billion from consumer activity and $236 billion from institutional activity.

The $295 billion figure was 24% higher than Coinbase’s $237 billion second-quarter total. It remained a venue-specific measure, however, not total cryptocurrency-market turnover. Coinbase also said its volume growth trailed the broader spot market, primarily because activity in stablecoin pairs was lower.

The quarter included Coinbase’s August 14 acquisition of Deribit. Coinbase attributed $52 million of third-quarter institutional transaction revenue to Deribit and said options activity produced record notional volumes. These were company-reported measurements and did not establish that every derivatives product or geography was growing at the same rate.

Stablecoins become a larger business line

Subscription and services revenue was $746.7 million, up from $556.1 million in the third quarter of 2024. Within that category, stablecoin revenue increased to $354.7 million from $246.9 million.

Coinbase said average USDC held in eligible Coinbase products reached approximately $15 billion during the quarter. It also reported that USDC’s market capitalization reached $74 billion. The filing tied stablecoin revenue to balances both on and off Coinbase, but those revenue figures should not be treated as a direct measure of payment adoption: balances can support trading, treasury management, rewards and other uses as well as payments.

At September 30, Coinbase reported $515.9 billion in customer crypto assets and USDC held in custodial products at fair value. The company did not recognize those customer assets on its condensed consolidated balance sheet. Their reported dollar value depended on market prices at the measurement date, so an increase could reflect asset appreciation, customer inflows or both.

What the market reaction established

Reuters reported that Coinbase Class A shares rose more than 3% in after-hours trading following the October 30 release. That observation concerns the post-market window, not the regular-session close, and Reuters did not specify one fixed timestamp for the move. It supports evidence of an immediate favorable reaction but cannot isolate earnings from other after-hours information or establish a lasting valuation change.

The larger institutional signal was the business mix. Coinbase still depended heavily on transaction activity and crypto prices, yet its filings documented meaningful revenue from stablecoins, staking-related blockchain rewards, financing, custody and derivatives. That diversification reduced neither regulatory uncertainty nor market cyclicality, but it showed that a major U.S. crypto intermediary was developing several distinct ways to earn revenue from the same underlying digital-asset economy.

Limits of the October 30 record

The quarterly financial statements were unaudited, while several operational measures and market-share characterizations came from management. Adjusted EBITDA and adjusted net income were non-GAAP measures, so this reconstruction relies principally on GAAP revenue and net income. Later quarters are not used to judge whether the trends identified on October 30, 2025 persisted.
