Coinbase Q3 2026 Earnings: Prediction Markets Offset Falling Spot Trading

Coinbase's third-quarter 2026 earnings, released on October 29, 2026 through a shareholder letter and a 10-Q for the quarter ended September 30, showed retail spot crypto trading still shrinking while new products kept transaction revenue roughly steady [1][2]. Three questions framed the quarter: whether prediction markets and derivatives could keep transaction revenue falling more slowly than spot trading, whether record USDC balances could protect stablecoin income, and whether expenses would stay within guidance after the layoffs. Consumer spot trading volume fell another 9% from the prior quarter, yet consumer transaction revenue was roughly flat, confirming the first point for a second quarter [1][3]. Stablecoin revenue rose 5%, but USDC rewards grew faster; adjusted expenses came in below the low end of guidance, and adjusted EBITDA rose to $333 million, partly because higher crypto prices produced gains on crypto assets [1][2]. Revenue now depends less on the spot trading cycle, but part of the profit improvement is hard to repeat.

Coinbase is the largest regulated crypto asset trading and custody platform in the United States, serving retail and institutional customers [4]. Roughly half of its revenue comes from trading fees charged on volume, and the other half comes from its share of USDC reserve income under the Circle arrangement, staking commissions, lending interest and Coinbase One subscriptions [1][4].

Prediction markets cushioned consumer transaction revenue

Consumer transaction revenue fell more slowly than consumer spot trading volume for the second straight quarter. In the third quarter, consumer crypto spot trading volume was $23.4 billion, down 9.3% from the second quarter and 59% from a year earlier; consumer transaction revenue was $450 million, down only 0.4% from the second quarter [1][2]. In the second quarter, the two had fallen 24% and 20%, respectively [3]. As a result, consumer transaction revenue as a share of consumer spot volume rose from 1.75% in the second quarter to 1.92%.

Prediction markets were the main offset. Their annualized revenue exceeded $200 million, compared with more than $100 million in the second quarter [1][3]. On an annualized basis, that implies a quarterly increase of at least about $25 million. The CFO said prediction markets and derivatives together made up about 25% of transaction revenue and were not cannibalizing spot trading, but the company did not disclose cohort data [5].

The new revenue carries higher costs. Prediction markets require Coinbase to pay exchange fees: the "other" line in transaction expense rose to $45 million from $9.6 million a year earlier, and transaction expense as a share of net revenue rose 32 basis points from the prior quarter to 16.8% [1][2]. Institutional transaction revenue fell 8% from the prior quarter to $91.65 million, and total transaction revenue was $590 million [1][2]. Fourth-quarter transaction revenue through October 25 was about $165 million, a slightly higher daily average than in the third quarter, and the company cautioned against extrapolating it; the INTX and Deribit integration was completed in October, and the company said volumes could be volatile in the near term [1].

USDC income and the cost base

Stablecoin revenue recovered, but its net contribution rose only slightly. Average USDC held in Coinbase products reached a record $22 billion, and stablecoin revenue was $307 million, up 5% from the prior quarter; USDC rewards were $129 million, and their share of stablecoin revenue rose from 40.8% to 42.1% [1][2]. After rewards, the contribution was about $178 million, slightly above about $173 million in the second quarter. Subscription and services revenue was $570 million, in the upper half of guidance [1].

The cost reductions have arrived, but part of the profit rebound is hard to repeat. Adjusted expenses were $975 million, below the low end of the $980 million to $1.08 billion guidance range, and the company attributed lower technology and development expense to a full quarter of the May layoffs [1]. Adjusted EBITDA rose by about $125 million from the prior quarter: lower cash expenses contributed about $52 million, and crypto assets held for operations swung from a $31.7 million loss to a $26.1 million gain, contributing about $58 million [1]. The company cut its full-year adjusted expense guidance to $4.15 billion to $4.30 billion, but its fourth-quarter guidance of $1.007 billion to $1.157 billion is above the third-quarter actual because of higher USDC rewards and performance marketing [1].

Conclusion

The third-quarter report strengthens the case that Coinbase's revenue is diversifying: while retail spot trading kept shrinking, prediction markets and derivatives held consumer transaction revenue steady [1]. On profit, the layoff savings have shown up, but exchange fees lower the margin on the new revenue, and the EBITDA rebound partly depended on crypto prices. On cash, operating cash flow for the first nine months was $786 million, down from $1.80 billion a year earlier [1]. The fourth quarter needs to show three things: whether the revenue-to-volume ratio holds above 1.75% after the price rebound and the exchange integration, whether institutional transaction revenue stops declining, and whether EBITDA excluding crypto asset gains and losses stays above the second-quarter level as expenses rise.
