Energy markets ran on three storylines today. A long running scandal over Chinese carbon credits sold into Europe got a new chapter. The Iran war kept squeezing oil, gas, and now sulphur. And the AI buildout kept pulling capital into long dated bonds. Each thread has different drivers but they share one feature: rules and prices that worked last cycle are starting to fail.
A new Ethereum core change is moving through go ethereum, the most widely deployed client. It raises the gas cost for opcodes and operations that grow chain state, and it tightens how the network refunds gas when authorization slots clear. The pull request crossed another milestone on May 22, 2026 with regenerated tracing code, which usually signals that the implementation is converging on a final shape.
Alphabet trades like an ad company but operates like a holding firm. Inside the GOOGL share sit a minority piece of SpaceX, a majority piece of Waymo, and a growing AI infrastructure tab. Today’s notes tie those threads together with a side trip into Ethereum protocol plumbing.
Nvidia delivered another beat and added $80 billion of buyback authorization. Bloom Energy locked in a power supply deal with cloud builder Nebius worth up to $2.6 billion. The cluster of AI infrastructure prints landed against a tape where the equity risk premium is now negative for the first time since the dot com era.
Ethereum’s main execution client just landed a small but practical change. Code cache hit and miss meters now ship as first class Prometheus signals, so operators no longer have to dig through slow block JSON dumps. The kind of unglamorous engineering that compounds across the network.
The AI capex story in 2026 is no longer just about Nvidia GPUs. It is about everything around them: high bandwidth memory from Micron, on site power from Bloom Energy fuel cells, compute capacity from Nebius, and robotics platforms tied back to the same chip stack through partnerships like Nvidia and Kawasaki. The interesting numbers are now in the second derivative, not the headline GPU shipments.
Three signals from the May 22 tape point in the same direction. Public money is rotating into quantum and chips. Large AI buyers are reshuffling vendors. Robots are getting paired with general purpose AI hardware. None of these threads are new on their own, but they all showed up in the same window.
