"We made a very deliberate decision to invest in diversifying the business. Roughly 50% of Coinbase's revenue now comes from non-trading fees." @ShanAggarwal of @coinbase with @hosseeb of @dragonfly_xyz on the Main Stage at ETHConf.

I love people with ADHD because they never actually forget anything. You just have to say the right words to activate them like a sleeper cell and then they awaken with all of the knowledge on a very niche subject they studied for 3 months straight 6 years ago.

Coinbase is the winner of AI-native finance. We believe $COIN can be a ~$300B company (6x from today) Artemis open sources the BEST Coinbase financial model using onchain data. You can now build models like the BEST analysts. We believe Coinbase is WINNING in stablecoins, agentic commerce โ€“ not just as a crypto exchange. Hereโ€™s the core assumptions > Stablecoin supply reaches ~$3T in 2031 (~US Treasury official estimates) > USDC is 30% of stablecoin supply > Agentic Commerce ~$7.5T in yearly spend in 2031 > Coinbase Agentic Commerce is able to monetize and captures 1bp of the entire TAM > Net transaction revenue grows 11% CAGR > Subscription & Services goes from 40% of total revenue to 65% of revenue in 2031 In our bull case, Coinbase does ~$23B revenue in 2031 with ~$10B of net income. At 30x PE that assumes ~$300B of marketcap (6x from today) Full 12 page thesis drops at 5pm ET ๐Ÿ‘€

Stablecoins = up and to the right ๐Ÿš€ Thanks for having me on @therollupco!
How fast is the stablecoin market actually growing? Jonathan King from Coinbase Ventures: 33T total in 2025 in transactions. 10T in January 2026 alone. 26.5T in just the last couple months. The pace is structurally accelerating, Genius Act, institutional adoption, cross-border payments, emerging markets stablecoin rails, localized stablecoins are all stacking. Stablecoins and payments are Coinbase Ventures' bread and butter for a reason.

the original sin of the internet was the failure to build a native payment layer. for decades everything went digital except money. but that era is now over. stablecoins are fixing it and faster than anyone expected. I wrote about what we're building @Coinbase and why it matters now.
