In September 2025, developments ranging from a $300 million treasury shift by a Nasdaq-listed firm to the steady as the stock surge 500%
Solana exchange-traded fund (ETF) revealed a measurable build-up of institutional exposure to SOL. These facts, backed by filings and press releases, show a steady movement of capital into Solana that goes beyond retail speculation.
Institutional treasuries make the first move
In mid-September 2025, Brera Holdings, a Nasdaq-listed company, announced a rebrand to “Solmate” alongside a strategic pivot to Solana.
The plan included a $300 million private placement backed by investors in the United Arab Emirates and supported by ARK Invest.
 
The Financial Times reported the details in September , 2025, marking one of the largest publicly disclosed treasury allocations to Solana to date.
The move demonstrates that listed firms are beginning to treat Solana not just as a network for decentralized finance but as a treasury asset.
Solana ETFs gaining traction
Product development has also accelerated. The REX-Osprey Solana + Staking ETF, listed on the Cboe BZX exchange under the ticker SSK, launched in July 2025.
This vehicle provides a regulated entry point for wealth managers, pensions, and other institutions that may not want to custody SOL directly but still want exposure to its performance and staking yield.
Analysts noted that Solana could be among the tokens to benefit from this policy shift. Faster approvals mean more vehicles could be listed in the coming months, giving institutions broader access to SOL through familiar brokerage channels.
ETF assets under management provide another measurable signal, with daily net inflows and NAV statements tracked by exchanges.
Institutional participation changes the supply dynamics of any crypto asset. ETFs and trusts often move tokens into custodial accounts that reduce liquid float, while treasury allocations remove coins from exchanges for long-term holding.
Several events will provide concrete evidence of how institutional demand for Solana is evolving. The SEC’s new approval framework could bring additional ETF products to market in October and November 2025.
Weekly AUM disclosures from the REX-Osprey Solana ETF will remain a direct measure of flows. Any new treasury announcements, similar to Brera’s $300 million commitment, would add to the picture of institutional engagement
The story of Solana in 2025 is increasingly one of institutional adoption. A $300 million treasury allocation by a listed firm, the rapid growth of a Solana staking ETF, and regulatory changes that speed ETF approvals are all confirmed, dated developments.
These moves indicate that institutions are quietly accumulating SOL, creating structural demand that can be tracked through filings and assets under management.
Whether this accumulation leads to a breakout will depend on the pace of inflows in the months ahead, but the evidence already points to Solana becoming a more established part of institutional crypto portfolios.
