Coinbase FY 2025 Total Revenue Estimate: $7,196M Q1-Q3 actual revenue totals $5,400M. My Q4 estimate is $1,796M, roughly 2.7% below consensus (~$1,845M), driven by five data-backed assumptions. Consumer ($715M): Q4 spot volume was approximately $256B, with consensus consumer volume near $54B at an implied take rate around 130bps. Robinhood reported Q4 crypto revenue down 38% YoY with volumes off 52%, which is a meaningful read-through for retail activity across exchanges. I modeled a slight premium over the Coin Metrics base case of $708M given Coinbase's more crypto-native user base, though the BTC-heavy Q4 trading mix compressed altcoin take rates and limits that upside. Institutional ($203M): Deribit's first full quarter post-acquisition. October set an all-time record at $266B notional, and total Q4 derivatives volume reached $1.26T. At roughly 9bps on $228B of institutional volume, this represents a meaningful structural shift in Coinbase's revenue composition compared to a year ago. Stablecoin ($374M): I used daily USDC market cap data from CoinGecko rather than quarterly averages. Average Q4 supply was $76.2B, 2.8% above the Coin Metrics estimate of $74.1B. Back-calculating Coinbase's effective yield from Q1-Q3 results (which inherently captures the Circle revenue share) and applying 13bps of compression for two Fed rate cuts gives an effective rate of 1.95%, down from 2.08% in Q3. Base ($67M): Blockworks' Base L2 income statement shows Coinbase's Q4 take at $16.2M, up 17.4% QoQ. Validation: Total subscription and services of $736M falls within Coinbase's own $710-$790M guidance, positioned in the lower half given rate cuts and declining asset prices. Coinbase disclosed approximately $385M in October transaction revenue. My Q4 total of $985M implies November and December averaged $300M per month, a 22% decline from October that aligns with the broader crypto pullback through year-end. #CoinbaseChallenge
