Coinbase Global (NASDAQ: COIN) posted Q3 net income of $719M, or $2.51 diluted EPS, crushing analyst estimates of a $0.23 loss. The headline beat is almost entirely a $715M gain on crypto assets held for investment. Strip that out, and the underlying business faced pressure that's hard to ignore.
Total revenue of $1.22B was flat sequentially but down 35% from $1.87B a year ago. Crypto asset volatility hit multi-year lows, suppressing trading activity across the board. Transaction revenue fell 44% Y/Y to $590M. Consumer transaction revenue of $450M was roughly flat Q/Q but down sharply from $844M in Q3 2025. Institutional transaction revenue of $92M fell 8% Q/Q, roughly in line with broader market volume declines.
This is not a Coinbase-specific problem. Total market crypto spot trading volume fell 6% Q/Q and derivatives volume dropped 11% Q/Q. The company's response has been to lean into diversification, and that strategy is showing results. Subscription and services revenue reached $570M, or 49% of net revenue, up from 48% in Q2 and 41% in the year-ago quarter. Stablecoin revenue of $307M rose 5% Q/Q, driven by a new all-time high in average USDC held in Coinbase products at $22B, or roughly 30% of average USDC market cap. The full-quarter impact of the Hyperliquid USDC balance, which arrived in June, contributed to that growth.
Prediction markets are the surprise standout. The product surpassed $200M in annualized revenue with 82% quarterly compound growth since launch. Daily prediction market traders rose over 60% Q/Q, and the company noted that prediction market users are driving incremental spot volume. This revenue stream did not exist in any meaningful form two years ago. It is cushioning the blow from the trading downturn.
Adjusted EBITDA rose 60% Q/Q to $333M, marking the 15th consecutive quarter of positive adjusted EBITDA across market cycles. That metric strips out the crypto investment gains and stock-based compensation, giving a cleaner view of cash operating performance. Adjusted expenses of $975M came in below the company's Q3 outlook of $980M-$1,080M, driven by lower professional services spend and a full quarter benefit from May 2026 cost reductions. Headcount fell to 4,204 from 4,321 in Q2.
Management lowered and narrowed full-year 2026 adjusted expense guidance to $4.15B-$4.30B from $4.20B-$4.45B, a $100M reduction at the midpoint. That is the second cut this year. Q4 guidance for subscription and services revenue of $550M-$630M implies a sequential decline from Q3's $570M at the midpoint, suggesting stablecoin and blockchain rewards revenue may moderate. Adjusted expenses for Q4 are guided to $1,007M-$1,157M, up from Q3's $975M, driven by higher USDC rewards costs and performance marketing.
The buyback program continues to offset dilution. Coinbase repurchased 10.2 million Class A shares in Q3, returning over $2B to shareholders since the program began. With $2B remaining in authorization and shares outstanding essentially flat at 265M, the company is managing dilution aggressively. The buyback pace looks aggressive given that adjusted net income was just $78M in Q3, though the fortress balance sheet of $8.6B in cash and equivalents provides the cushion.
Coinbase is navigating a low-volatility environment better than it would have three years ago, thanks to subscription revenue and prediction markets. But transaction revenue remains the profit engine, and that engine is idling. The Q4 guidance implies management expects no near-term volatility pickup. Until crypto volatility returns, the earnings story will be about cost control and diversification, not top-line growth.
