The breakdown This Week by Asset

Asset	This week's activity	Net USD · share
BTC 3 entities		$49.0M 74.1%
SOL 1 entity		$17.1M 25.9%

SOL treasury adoption crossed a threshold this week: one new corporate stacker (SOL Strategies Inc) deployed $17.1M in Solana, or 26% of the week's total corporate treasury activity by USD value. BTC remains dominant by dollar volume, but SOL's entry signal marks a shift in which tokens corporate treasuries are diversifying into—previously, all four weekly filers targeted BTC alone.
