June 2026 was a difficult month for major cryptocurrencies and their supporting institutions. Bitcoin and Ethereum each lost around a fifth of their value, Strategy disclosed its first Bitcoin disposals in years, The Wall Street Journal investigated Polymarket's social media promotions, and the Ethereum Foundation cut staff and revised its budget. Behind the headlines, there were important differences between confirmed events, market valuations and corporate plans.

Bitcoin fell roughly 20% in June

According to historical Bitcoin prices, BTC declined from roughly $73,600 at the start of June to about $58,600 at the June 30 close, a loss of approximately 20.4%. For companies holding significant Bitcoin reserves, such a fall sharply reduces the market value of their assets, but does not automatically create an equivalent realized trading loss.

Strategy sold BTC for the first time since 2022, then kept buying

On June 1, Michael Saylor's Strategy disclosed the sale of 32 BTC for approximately $2.5 million. The timeline matters: the sale occurred between May 26 and May 31 and was merely reported in June. It was the first known sale since December 2022, not the first in the company's history.

The small sale was intended to support distributions to preferred shareholders. Yet Strategy did not abandon its accumulation strategy. It resumed sizable purchases during June, and by June 30 held 846,000 BTC, compared with 843,706 at the end of May. Its net Bitcoin holdings had therefore increased.

On July 6, a subsequent filing covering June 29–30 disclosed another sale of 1,363 BTC for around $80.8 million, at an average net price of $59,256 per coin. The proceeds were intended for preferred-share dividends and to replenish its cash reserve. The change marked a willingness to use Bitcoin for liquidity management, even while retaining a large long-term treasury position.

Strategy’s $14 billion paper shortfall is not proof of insolvency

According to Strategy's subsequent quarterly filing, its 846,000 BTC held on June 30 had an aggregate acquisition cost of $63.94 billion and a market value of $49.67 billion. The resulting $14.27 billion difference was a mark-to-market shortfall against historical purchase cost, not money already lost through the liquidation of the entire reserve.

Separately, Strategy recorded an $8.32 billion digital-asset loss for the second quarter, including $8.31 billion of unrealized revaluation losses. That quarterly accounting figure is not interchangeable with the gap between its total Bitcoin cost basis and current market value.

On June 29, the company adopted a BTC Monetization Program and updated its cash-reserve policies. The program allowed potential BTC sales for certain obligations, including up to $1.25 billion to replenish the dollar reserve. That reserve stood at $2.55 billion on June 28. The framework did not establish an imminent financial failure, but demonstrated the growing importance of dividend obligations and capital-market access for Strategy's balance sheet.

WSJ investigation: Polymarket promotions featured simulated wins

On June 21, The Wall Street Journal published an investigation into how Polymarket was promoted on social media. Reporters reviewed 1,105 videos from ten creators and found repeated use of near-identical copies of the prediction market website to stage bets. The videos depicted approximately $1.9 million in wagers that had never actually been placed.

In 118 clips, creators appeared to celebrate almost $900,000 in winnings. According to the Journal's reconstruction, real wagers with those outcomes would instead have lost more than $166,000. One example involved an apparently winning bet on something Donald Trump would say, illustrated using footage from a different month.

Influencer payments and Polymarket's response

Creators interviewed by the newspaper said they typically earned around $2,000–$3,000 per month, while paid relationships often went undisclosed. A marketing contractor coordinated the wider redistribution of the clips; according to another report on the investigation, the campaign attracted more than 140 million views.

Polymarket said it remained committed to fair and transparent markets and pledged to conduct a comprehensive audit of promotional content. The WSJ findings are reported investigative claims, not a court ruling that each individual video broke the law. Nonetheless, they raise questions about undisclosed sponsorships, the authenticity of displayed wins and the advertising rules surrounding financial and event contracts.

Ethereum lost 21.7% in June

Ethereum also suffered a difficult month. Based on Binance ETH/USDT trading data, the asset fell from about $2,007 at the start of June to $1,572 at the June 30 close, a 21.67% decline. Its monthly low was around $1,506. The market decline coincided with an internal restructuring of the Ethereum Foundation, but timing alone does not establish that personnel changes caused the entire ETH sell-off.

Ethereum Foundation cut 54 positions and reorganized operations

On June 23, the Ethereum Foundation formally announced the departure of 54 staff members, approximately 20% of its workforce. The cuts concluded a months-long restructuring that created five main areas of work: protocol, access, users, community and institutional engagement, supported by separate operational and management groups.

Ethereum co-founder Vitalik Buterin also outlined a roughly 40% reduction in the Foundation's 2026 budget. A longer-term goal was to reduce annual expenditure from approximately 15% of treasury assets to around 5% by 2030. It is that future treasury-spending ratio that may be described as a threefold reduction, not an immediate threefold cut to the entire budget.

Leadership transition: Hsiao-Wei Wang's departure

On June 18, Hsiao-Wei Wang resigned as co-executive director and board member of the Ethereum Foundation. Fellow co-executive director Tomasz Stańczak had stepped down in February. Other prominent researchers and executives also departed in the first half of 2026; some media outlets counted as many as nine senior changes, although totals vary depending on whether sabbaticals and different leadership roles are counted.

The Foundation said the new structure would focus on base-layer protocol security, censorship resistance, privacy and open infrastructure. Lower staffing levels demonstrate a change in priorities and spending; they do not mean that Ethereum development has ceased. Independent teams across the ecosystem continue building network technology.

What the developments meant for affiliate marketing

For marketers, the Polymarket investigation highlighted the risks of undisclosed sponsorships, staged results and unsupported earnings claims. Promotion of financial and event-based products requires clear commercial disclosures, compliance with platform policies and an honest distinction between demonstrations and real trades. For teams relying on crypto payments, June also reinforced the value of liquidity reserves, diversified settlement assets and counterparty risk controls.
