New developments this week show crypto pushing deeper into mainstream finance, corporate strategy, and even global sports.
This week’s highlights include Ethereum’s three-month high, a strategic $1B shelf filing tied to Solana, and a Champions League finalist adding Bitcoin to its books.
PSG becomes first football club to add Bitcoin to its balance sheet
Paris Saint-Germain (PSG), one of Europe’s top football clubs and a finalist in the UEFA Champions League final this Saturday, revealed it has added Bitcoin to its corporate treasury, becoming the first sports organization globally to do so.
The announcement at the Bitcoin 2025 conference in Las Vegas aligns with the club’s strategy to engage its 500 million-strong fan base with forward-thinking financial tools.
PSG Labs head Par Helgosson said the move is part of a larger effort to align with “next-generation” monetary systems, as Bitcoin adoption continues spreading across both financial and cultural institutions.

BlackRock’s IBIT dominates ETF inflows with $4B surge
BlackRock’s iShares Bitcoin Trust (IBIT) has solidified its status as the U.S. spot Bitcoin ETF leader, drawing 96% of total net inflows during a 10-day streak that brought in $4.2 billion.
On May 28 alone, IBIT attracted $481 million, more than the entire market, while rivals like Ark’s ARKB and Fidelity’s FBTC posted outflows.
IBIT has now seen 33 straight days without net redemptions and controls nearly 80% of trading volume among Bitcoin ETFs.
It ranks as the 23rd largest U.S. ETF by AUM, highlighting how institutional flows are increasingly concentrated in a single product.
Bank of Korea considers national stablecoin amid USDT dominance
The Bank of Korea (BOK) is exploring the issuance of a state-backed stablecoin to reduce reliance on foreign digital currencies like Tether’s USDT and Circle’s USDC.
Revealed at the Blockchain Leaders Club event, the initiative would link deposit tokens to public blockchains under the central bank’s digital currency framework.
South Korean regulators are concerned about capital flight and loss of monetary control, with USDT alone representing 47.3% of national crypto outflows in Q1.
Political leaders are now pushing for a Korean Won-pegged alternative, with local banks already forming a consortium to develop a domestic solution.
Ethereum rallies 4% to 3-month high on ETF inflows and upgrades
Ethereum led crypto markets this week, jumping nearly 4% to briefly touch $2,725, its highest price since February.
The move came as Ethereum ETFs posted $85 million in inflows on May 28, marking their eighth straight day of gains.
Analysts attribute the rally to the successful Pectra network upgrade, which boosted scalability and improved staking mechanics.
Additional momentum came from SharpLink Gaming’s $425 million Ethereum-based treasury plan and the appointment of Ethereum co-founder Joseph Lubin as chairman.
Lubin called Ethereum the “protocol moment that our financial system needs”.
GameStop adds 4,710 BTC to treasury in bold corporate shift
GameStop, the video game retailer known for its meme stock legacy, has purchased 4,710 Bitcoin worth approximately $512 million.
Funded via a $1.5 billion convertible note offering, this marks GameStop’s first foray into digital assets as a treasury reserve.
The move aligns the company with a growing number of firms, including Michael Saylor’s Strategy (formerly MicroStrategy), which views Bitcoin as a hedge against fiat currency risks.
The announcement, made via GameStop’s X account and confirmed in SEC filings, signals a broader trend of corporate adoption amid increasing regulatory clarity and rising macroeconomic uncertainty.

SOL Strategies files $1B shelf prospectus to scale Solana investments
SOL Strategies, a Canadian public firm focused on the Solana blockchain, has filed a $1 billion base shelf prospectus to expand its capital-raising capabilities.
While no immediate offerings are planned, the filing gives the firm flexibility to issue shares, debt, and other instruments without additional regulatory hurdles.
CEO Leah Wald said the move supports their long-term growth strategy and positions them to act swiftly on investment opportunities in Solana’s high-speed ecosystem.
The company already secured $500 million in funding this year and trades under the ticker HODL on the Canadian Securities Exchange.
Stablecoin payments hit $94B fueled by B2B demand and global interest
Stablecoin payments reached $94.2 billion between January 2023 and February 2025, driven largely by B2B transfers and card-linked spending, according to Artemis.
Tether’s USDT remains the preferred option, especially for large-scale business payments on Tron and Ethereum, where average B2B transaction sizes exceed $219,000.
Governments and financial institutions are taking note: the UAE and EU have already approved operational stablecoin frameworks, while U.S. lawmakers are racing to catch up.
Meanwhile, U.S. banks are exploring a joint stablecoin product, and Stripe just rolled out stablecoin accounts for users in over 100 countries.
