Coinbase -- How the Business Works

Revenue by Segment -- FY2025 (~$7.2B)

Subscription and services revenue is the key to the bull case. At $2.83B (+23% YoY), this segment is more predictable than transaction revenue and growing faster. USDC stablecoin economics ($1.35B) are the anchor -- Coinbase earns yield on all USDC in circulation regardless of where it is held, creating a durable revenue stream tied to stablecoin adoption rather than crypto trading volume. USDC market cap grew 72% in 2025, outpacing USDT (32%), supported by MiCA regulation in Europe. However, this segment is decelerating: YoY growth slowed from +37% in Q1 to +13% in Q4, and interest rate cuts directly compress stablecoin and finance fee income.

Subscription & Services Components -- FY2025

USDC Revenue Flywheel

Oligopoly hard gate: PASSED. Coinbase clears the 30%+ market share threshold in multiple meaningful segments. US crypto exchange share of ~60-65% makes Coinbase the clear price-setter, with Kraken (~15%) and Robinhood (~10%) as distant followers. Crypto ETF custody at ~80%+ is a near-monopoly with enormous switching costs. Base L2 at ~46% of TVL (and 62% of L2 revenue) is the dominant Layer 2 network. USDC economics represent one half of the stablecoin duopoly (USDC + USDT = 85%+ of all stablecoins). However, global exchange share is low at ~5-7% and declining as Binance (38%) and Asian exchanges grow faster.

Switching costs are deep in custody, moderate in exchange. Could ETF issuers replace Coinbase within 12 months? Very difficult -- regulatory approvals, operational integration, and security audits for institutional crypto custody take years. For US exchange users, switching is easier but Coinbase benefits from brand trust, regulatory compliance, and the largest liquidity pool. For USDC economics, there is no switching -- Coinbase earns revenue on all USDC regardless of where it is held. The primary vulnerability is global exchange share, where Coinbase is a minor player and losing ground to Binance and Asian competitors.

Coinbase operates a three-layer flywheel. (1) The exchange platform attracts users through regulatory trust and liquidity, generating transaction revenue. (2) Users holding assets on-platform generate subscription revenue through staking, USDC yield, and custody fees -- this is the "sticky" revenue layer that persists even when trading slows. (3) Infrastructure investments (Base L2, Deribit derivatives, Everything Exchange) expand the ecosystem and create new revenue streams. The Deribit acquisition immediately adds derivatives cross-sell to institutional users. Base L2 positions Coinbase as an Ethereum infrastructure provider, not just an exchange. The critical question is whether subscription and services growth can offset the structural cyclicality of transaction revenue -- FY2025 showed progress (S&S rose to 39% from 37%) but not yet enough to de-risk the earnings profile.

Business Model Flow

Addressable Market Summary -- 2026 Estimates

Extreme earnings cyclicality is the defining business model risk. Transaction revenue swings wildly with crypto cycles -- quarterly revenue ranged from $674M to $2.3B over the past 12 quarters. GAAP EPS halved from $9.48 to $4.45 YoY, and Q4 2025 posted a -$2.49 loss. Net income swung from +$1.4B to -$667M in consecutive quarters. Forward P/E of 30.3x is 22% above the peer average (24.7x) with consensus EPS estimates cut 31-42% in the past 30 days. Long-term debt grew 40% to $5.9B versus 9% revenue growth. Insider selling totaled $315M+ over 90 days with zero purchases -- a meaningful conflict with management rhetoric projecting 10-20% of global GDP on crypto rails. Data breach ($180-400M exposure) and SEC investigation are ongoing. Zero China exposure is a positive, and regulatory trajectory (GENIUS Act, SEC/CFTC MOU) is favorable, but near-term risk/reward is challenging at current valuations.
