How to Read Coinbase's Earnings: Trading Revenue, USDC, and Valuation Risks

Market Trends

04 October 2026

The most common mistake when reading Coinbase's earnings report is treating total revenue as one single thing. The company's revenue structure is changing significantly: trading revenue is still highly tied to crypto market conditions, but subscription and services revenue is making up a larger share, with USDC interest being the core variable. These two parts are driven by different factors and need to be looked at separately.

Trading Revenue: Quarter-over-Quarter Matters More Than Year-over-Year

Trading revenue is the most watched part of Coinbase's business, and also the most volatile. In Q3 2025, trading revenue was about $1.05 billion, up 37% quarter-over-quarter and about 84% year-over-year, mainly driven by higher trading volume from market volatility during the quarter. By Q4, trading revenue dropped to about $983 million, down 36.8% year-over-year.

Year-over-year data has limited value in the crypto industry because the base period may have been in a completely different market cycle. Quarter-over-quarter changes better reflect current business momentum. If trading revenue drops noticeably from the previous quarter, you need to compare it with the total crypto market trading volume during that quarter to determine whether it is an industry-wide contraction or a loss of Coinbase's own market share. Coinbase's full-year 2025 trading volume grew 156% and its market share doubled, but spot trading volume fell 50% in Q1 2026. This is the industry backdrop you need when judging the direction of trading revenue.

USDC Revenue: Look at Both the Balance and the Interest Rate

Subscription and services revenue is becoming an increasingly important part of Coinbase's earnings report. In Q3 2025, it reached about $747 million, up 34% year-over-year. Stablecoin revenue was about $355 million, up 44% year-over-year. This part of revenue comes from interest earned on USDC reserves, which Coinbase shares with Circle.

USDC revenue is driven by two variables: the average circulating supply of USDC and the interest rate level. In Q3 2025, USDC's market cap hit a record high of about $74 billion, and Coinbase's platform held an average of about $15 billion in USDC, making it the largest distribution channel for USDC. But falling interest rates can partially offset the effect of growing circulation. Coinbase's earnings report explicitly stated that a 93 basis point drop in interest rates had a negative impact of about $79.8 million on stablecoin revenue, although the growth in circulation brought a larger positive contribution.

By Q1 2026, USDC-related revenue grew 11% year-over-year to $305 million, but the overall guidance for subscription and services revenue was lowered to a range of $550 million to $630 million. The company explained the reason as "lower average USDC market cap and interest rates." This means that even if USDC circulation keeps growing, falling interest rates could still put pressure on this revenue line.

Valuation: What Is the Market Pricing In?

Coinbase's valuation metrics fluctuate widely. As of early October 2026, its forward price-to-earnings ratio was about 54x, and its price-to-sales ratio was about 8.8x. Back in September 2025, the price-to-sales ratio had reached 13.35x, with a forward P/E of about 49x. The price-to-sales ratio has contracted more than the P/E ratio, indicating that the market is adjusting its expectations for revenue growth.

A key assumption embedded in the current valuation is: can subscription and services revenue keep growing and eventually dominate total revenue? In Q1 2026, subscription and services revenue accounted for 41% of total revenue, up from 33% in the same period last year. If this ratio keeps moving toward 50%, Coinbase's revenue structure would look more like a financial infrastructure company with recurring revenue streams rather than an exchange purely dependent on trading volume. Whether the market is willing to pay a premium for this transformation depends on the actual growth rate of subscription revenue in the coming quarters.

What to Check When Reading the Earnings Report

First, check whether trading revenue and subscription revenue are moving in the same direction quarter-over-quarter. If trading revenue falls but subscription revenue stays stable or grows, it means the revenue structure is becoming more resilient. If both fall at the same time, the company is facing broader pressure.

Next, look at changes in the average market cap of USDC. This data is disclosed in the stablecoin revenue section of the earnings report. A rising average market cap means USDC adoption is expanding, but you need to combine it with interest rate changes to judge the net impact.

Finally, look at expenses and cash flow. In Q4 2025, operating expenses grew 21.8% year-over-year to $1.5 billion, and full-year operating cash flow fell 21.8%. If subscription revenue grows but expenses grow even faster, the improvement on the profit side will be eroded. Coinbase announced 700 layoffs at the end of Q1 2026, calling it a structural transformation toward becoming an "AI-native company." The expense trend in the following quarters will be the basis for verifying whether this claim is actually being implemented.
