Ether cleared $2,500 as its post-Pectra rebound accelerated

Ether extended one of its sharpest rallies in years on May 10, 2025, completing Coinbase Exchange’s UTC trading session at $2,583.80. The move carried ETH above $2,500 three days after Ethereum activated its Pectra protocol upgrade and placed the asset—not bitcoin—at the center of the weekend cryptocurrency market.

The timing made Pectra an important part of the market narrative. It did not prove that the software upgrade caused the price increase. Cryptocurrency markets were also responding to easing trade tensions, bitcoin’s return above $100,000 and the forced unwinding of bearish positions. The evidence supports a strong rally alongside those developments, not a controlled attribution of the move to any single catalyst.

What the Coinbase session recorded

Coinbase’s ETH-USD daily candle, measured from 00:00 through 23:59:59 UTC on May 10, opened at $2,345.42, traded between $2,317.73 and $2,600.60, and ended at $2,583.80. That was a 10.2% open-to-end gain, calculated from the venue’s unrounded figures.

From the May 7 UTC endpoint of $1,811.35 to the May 10 endpoint, ETH advanced 42.6%. That comparison begins after Pectra’s 10:05:11 UTC activation on May 7, but it remains a calendar-based market window rather than an event study.

Bitcoin rose much less during the May 10 UTC session. Coinbase’s BTC-USD market moved from $102,986.94 to $104,821.19, an open-to-end increase of 1.8%. Ether therefore outperformed bitcoin by approximately 8.4 percentage points in that specific venue and window. Those calculations do not represent a consolidated global price or an official closing auction: crypto trades continuously, and other exchanges can record different highs, lows and endpoints.

Bloomberg’s contemporaneous May 9 report had already characterized Ether as heading toward its strongest weekly gain since 2021. Its quoted price and return were publication-time snapshots, however, not the completed May 10 candle used in this reconstruction.

Why Pectra mattered to the narrative

Ethereum’s upgrade was scheduled for epoch 364032 at 10:05:11 UTC on May 7. Its changes included EIP-7702, which allowed externally owned accounts to delegate smart-contract functionality; EIP-7251, which raised a validator’s maximum effective balance from 32 ETH to 2,048 ETH; and EIP-7691, which increased Ethereum’s target blob count from three to six and the maximum from six to nine.

Those were material changes for wallets, validators and rollups. They gave traders a concrete protocol milestone after a period in which Ether had substantially underperformed bitcoin. The May 10 price action showed that market attention had shifted, at least temporarily, toward Ethereum’s technical roadmap and the possibility of renewed relative strength.

The market record established momentum, not adoption. A higher token price did not demonstrate that wallets had implemented EIP-7702 safely, that validators had consolidated balances, that rollup costs had permanently fallen or that demand for Ethereum blockspace had increased. Each operational claim required separate network measurements over a longer period.

Limits and later confirmation

The Ethereum Foundation’s June 3 protocol checkpoint later said Pectra had shipped without a hitch. That retrospective confirmation was not available on May 10 and is included only to clarify the protocol record; it does not explain the rally or validate contemporaneous trading claims.

The defensible May 10 conclusion is narrower: Ether completed a 10.2% Coinbase session above $2,500, sharply outperformed bitcoin over the same UTC window and extended a powerful rebound immediately following a major Ethereum upgrade. Whether that represented a lasting change in market leadership remained unresolved.
