The final week of June 2025 reinforced digital assets’ ascent into institutional finance. With major firms making long-term Bitcoin plays, ETF milestones being crossed, and blockchain infrastructure expanding into traditional payment systems, the sector continues to mature under the watchful eye of regulators and allocators alike.

‍

1. Semler Scientific Reveals Ambitious Bitcoin Accumulation Plan

Semler Scientific announced a bold 3-year strategy to acquire 105,000 BTC, positioning the move as a core treasury reserve diversification effort. The announcement was made via a press release, with the company citing Bitcoin’s long-term role as a store of value.

‍

Impact: This echoes MicroStrategy's playbook but at a new scale and cadence. Semler’s institutional-sized bet underscores growing confidence among public companies to use Bitcoin as a balance sheet asset, reinforcing its status as digital gold in capital markets.

2. Mastercard Integrates Chainlink for On-Chain Crypto Payments

Mastercard partnered with Chainlink to enable direct on-chain crypto purchases using its payment network. The integration allows smart contracts to connect seamlessly with Mastercard services, potentially unlocking Web3-native commerce.

‍

Impact: This collaboration represents a major step in merging traditional payments infrastructure with decentralized finance. It adds credibility to Chainlink’s enterprise value and signals that real-world asset (RWA) connectivity is entering a new phase of implementation.

‍

3. Truth Social Files for Dual Bitcoin and Ethereum ETFs

Truth Social expanded its ETF ambitions by filing for both Bitcoin and Ethereum spot ETFs with the NYSE. The move comes just one week after its Bitcoin-only filing was acknowledged by the SEC.

‍

Impact: While regulatory approval remains uncertain, these filings reflect how crypto exposure is being pursued across a wider spectrum of political and media-driven platforms. If approved, these ETFs could widen retail access and introduce new market dynamics.

‍

4. Grayscale Registers "Space and Time Trust" in Delaware

Grayscale quietly registered the Space and Time Trust (SXT) in Delaware, suggesting future expansion into data-focused blockchain products. Space and Time is a decentralized data warehouse that enables verifiable compute across Web2 and Web3.

‍

Impact: Grayscale’s move signals growing interest in decentralized data infrastructure. If this trust becomes investable, it could provide institutions access to a foundational layer of blockchain-powered analytics and RWA integrations.

5. ETF Watch: Milestones, Delays, and New Frontiers

‍

- Spot Bitcoin ETFs Surpass $1 Trillion in Cumulative Volume

The combined volume of U.S. spot Bitcoin ETFs has officially crossed the $1 trillion mark. Notably, BlackRock’s IBIT climbed to 4th place on the year-to-date (YTD) flow leaderboard, ahead of legacy equity ETFs.

‍

Impact: This milestone validates sustained institutional appetite for Bitcoin exposure through regulated vehicles. IBIT's ascent reflects increasing dominance among new entrants and affirms ETF flows as a key driver of Bitcoin’s price and market depth.

‍

- Polkadot ETF Delayed as Altcoin Products Face More Scrutiny

The SEC delayed a decision on 21Shares’ spot Polkadot (DOT) ETF, continuing its cautious approach toward altcoin-linked financial products.

‍

Impact: The delay reflects regulatory hesitation to greenlight altcoin ETFs beyond Bitcoin and Ethereum. However, consistent filings suggest issuers remain confident in eventual approval, particularly as staking and decentralization models become better understood.

‍

Closing Outlook

Week 26 reinforced the strength of crypto’s institutional foundation. Bitcoin continues to cement its position in corporate treasury strategy, while ETF flows break records and new filings broaden the asset class. The Mastercard–Chainlink integration points to an evolving payments stack, and Grayscale’s SXT trust hints at a deeper future for data interoperability in crypto. With ETF volume milestones and mainstream adoption crossing into real-world commerce, the market’s long-term narrative remains firmly intact.
