BTCS Makes Russell Microcap Index as Ether Treasury Companies Report Significant Growth

BTCS Added to Russell Microcap Index as Ether Treasury Strategy Gains Traction

BTCS Inc., a Nasdaq-listed blockchain infrastructure company, has officially joined the Russell Microcap Index — a development that may enhance its profile among institutional investors and ETF managers. The inclusion comes as a wave of publicly traded companies ramps up exposure to Ethereum (ETH), fueling notable equity gains in the process.

Maryland-based BTCS recently announced a $100 million capital deployment plan focused on expanding its ETH holdings and bolstering its validator infrastructure. Through its ChainQ analytics platform and Ethereum staking operations, BTCS positions itself at the forefront of the growing “on-chain treasury” movement.

The company’s stock surged over 22% in pre-market trading following the index addition, extending a month-long rally that has seen its shares double. The inclusion could boost passive inflows, as funds tracking the Russell Microcap Index reallocate capital.

BTCS isn’t alone in pursuing an ETH-focused treasury model. GameSquare (GAME) has also committed $100 million toward ether purchases and is holding an investor call this week to outline its broader blockchain strategy. Its stock jumped 45% in early trading.

Meanwhile, SharpLink Gaming (SBET) — now the largest known corporate ETH holder — climbed 16.6% in pre-market trading, adding to Tuesday’s 21.3% surge. The stock has more than doubled over the past month.

While ether is still down about 5% year-to-date, it has gained 20% in the last 30 days, buoyed by renewed corporate interest. Bitcoin, by comparison, is up more than 25.7% in 2025.
