Crypto in August 2025: Ethereum's Run to $4,900

2025-09-01

August was Ethereum's month. After years in Bitcoin's shadow, ETH finally took out its 2021 record, Bitcoin set another high of its own, and Washington opened the door to crypto in America's retirement accounts. Here is the recap.

Ethereum's Long-Awaited Record

Ethereum surged roughly 130% off its June low to an all-time high near $4,900 on August 22, finally eclipsing its 2021 peak. The rally was driven by relentless treasury-company accumulation and record spot-ETH ETF inflows -- including roughly $1 billion in a single day. Bitcoin set its own fresh high above $124,000 on August 14, and total crypto market cap pushed to around $4.1-4.2 trillion.

Crypto in Your 401(k)

On August 7, Trump signed an executive order directing the Department of Labor, SEC, and Treasury to open defined-contribution retirement plans -- a roughly $8.7 trillion market -- to alternative assets including crypto. On August 12, the DOL rescinded Biden-era guidance that had discouraged crypto in 401(k)s. The potential demand implications were enormous, even if actual allocations would take time to flow.

Another IPO Pops

The crypto-equity wave rolled on. On August 13, the Peter Thiel-backed exchange Bullish (BLSH) -- which also owns CoinDesk -- IPO'd on the NYSE at $37, above range, raising about $1.1 billion. The stock opened near $90, up 143%, before settling in the low $90s. It followed Circle and preceded Gemini in a banner year for crypto listings.

The Treasury Arms Race

By late August, BitMine (BMNR) held around 1.7 million ETH -- the largest Ethereum treasury company -- while SharpLink (SBET) reported roughly 798,000 ETH. Combined ETH treasuries approached $9 billion, a structural new source of demand that was both a tailwind for price and a concentration risk for the future.

Hacks

Roughly $163 million was stolen across about 16 incidents, up 15% from July, led by a single ~$91 million social-engineering loss and a ~$48-54 million breach of Turkey's BtcTurk.

The Takeaway

August showed leadership rotating from Bitcoin to Ethereum, a classic late-cycle signal, while policy kept widening the on-ramps for institutional capital. Rotation and momentum are exactly what quantitative models are built to catch. See where ours point now on the forecasts dashboard.
