Change from year-end 2025: The investment position was essentially a long-standing ~150,000-ETH corporate allocation rather than evidence of wholesale abandonment of ETH; Pollak said Coinbase had held roughly 150,000 ETH “for years.” Reporting also indicates Bitcoin increased during the first half of 2026 while ETH exposure edged lower, which supplies the factual basis for critics’ portfolio-reallocation observation.

What this does—and does not—answer about Base sequencer ETH: A large, retained corporate ETH balance weighs against the simple assertion that Coinbase has been indiscriminately “dumping ETH.” But a balance-sheet snapshot cannot trace the provenance of each ETH: it cannot demonstrate whether particular Base sequencer receipts were retained, sold for operating expenses, converted into BTC, or otherwise managed. The public allegation that Base-generated ETH was sold to buy BTC was expressly framed as an inference from filings, not proof of transaction-by-transaction causation.

Unstaking and Coinbase Prime transfers: The available evidence is insufficient to conclude whether those movements were treasury rebalancing, staking operations, OTC/customer facilitation, or liquidation. Transfers to Prime are not, by themselves, evidence of a sale; without wallet attribution, trade records, or a Coinbase disclosure, the motivation remains unresolved.

Pollak’s broader defense: He framed Coinbase as both a substantial ETH holder and an Ethereum participant—through Base’s use of Ethereum, support for EIP-4844, USDC-related infrastructure, and Base’s decentralization progress—rather than merely an entity extracting sequencer revenue. Contemporary reporting also described his response as rejecting moral judgments about ordinary Ethereum activity, including trading, DeFi, and memecoins.

Chaskin’s ecosystem argument: Jason Chaskin’s defense, echoed in the exchange, is that Coinbase’s relationship to Ethereum is integrated: it is an ETH holder, a Base operator/customer of Ethereum, a major custodian, and an on-ramp for users and assets. That is a stronger claim than “Coinbase never sells ETH,” but it is not a substitute for a transparent policy on sequencer-revenue conversion. Pollak specifically described Coinbase as a customer of Ethereum as well as a long-term ETH holder.

Treasury ETH is not customer ETH: Coinbase is unusually observable because it is a publicly traded U.S. company that files periodic financial reports. Its own corporate ETH—investment plus operational holdings—must not be confused with the far larger ETH it safeguards for customers and institutions. Coinbase reported that it serves as custodian for more than 80% of U.S. BTC and ETH ETF assets, illustrating the scale of custody distinct from corporate treasury ownership.
