Coinbase's Q3 profit jumps 66% — but a crypto-holdings gain does most of the lifting

Coinbase reported third-quarter net income of $719 million on Thursday, up 66% from $433 million in the same quarter last year, according to the company's earnings report as relayed by The Block. The headline number is real, but the composition matters: the quarter included a $715 million gain on crypto assets Coinbase holds for investment, versus a $424 million gain a year earlier. That mark-to-market swing accounts for nearly the entire reported profit.

Underneath it, the trading business softened. Total revenue was $1.22 billion — broadly flat from the prior quarter but down 35% year over year. Spot trading volume fell 8% quarter over quarter to $135 billion, though Coinbase said it continued to gain market share. Derivatives volume slipped 7% to roughly $986 billion; Bernstein noted industry-wide derivatives volumes fell 11% over the same period, so Coinbase lost less ground than peers.

The growth story the company is selling is diversification away from volatile spot trading. Prediction markets crossed $200 million in annualized revenue, doubling from about $100 million the prior quarter. Bernstein estimated prediction markets and derivatives together made up about 25% of transaction revenue — roughly 12% of total revenue. CFO Alesia Haas said subscription and services revenue now represents "nearly half of net revenue." Stablecoin revenue came in at $328 million, up 3% quarter over quarter, including $21 million from USDC held on Coinbase's own corporate balances.

The real-world read

Strip out the $715 million crypto-holdings gain and the quarter looks far less triumphant: operating revenue down a third year over year and spot volumes still falling. The "66% profit jump" headline leans heavily on a non-operating mark that moves with crypto prices and could reverse next quarter. CEO Brian Armstrong's line that Coinbase has a "strong right to win" in prediction markets is management framing, not a verified claim. The bullish price targets — Bernstein's $250, William Blair's ~$240, both reiterating Outperform — come from sell-side firms and should be read as their opinion, not a verdict. And the resilience narrative cuts both ways: diversification is helping precisely because the core trading engine is shrinking.

Opinion, and whose

Bernstein said prediction markets and subscription revenue "helped offset the softer crypto trading activity" and kept a $250 target (Outperform). William Blair said stablecoins, particularly USDC, "will revolutionize cross-border payments," valuing the stock near $240 (Outperform). Haas argued the newer lines make Coinbase "more diversified and resilient across market cycles." All are forecasts from interested parties.
