ETHGas said on Dec. 17, 2025 that it closed a $12 million fundraise led by Polychain Capital, with participants including Stake Capital, BlueYard Capital, SIG DT, and Amber Group, according to the company’s blog.
Alongside the raise, ETHGas said it debuted an Ethereum blockspace market with $800 million in commitments from validators, builders, and wholesale network participants. It described “pre-confirmations” as blockspace commitments that can be bought, sold forward, hedged, and allocated, with maturities “across a full curve,” user-defined placement within a block, and 10,000+ transactions-per-second settlement capability. ETHGas also said part of the raise will expand the Open Gas Initiative, noting 127,000+ Gas IDs generated and 270,622 ETH in historical gas spend surfaced.
Next, stakeholders will watch integration milestones and market depth, including whether pre-confirmations and gas sponsorship scale into more predictable execution and less gas volatility at the UX layer.
