Outflows from spot Bitcoin ETFs broke a nine-day streak ahead of the upcoming FOMC meeting, as Bitcoin hovered around $77,000 and traders gauged whether the market can hold that level.

Bitcoin mining firm Core Scientific will convert its Pecos, Texas facility into a high-density AI colocation data center, targeting total power capacity of 1.5 GW, the company said, according to Cointelegraph. About 1 GW is expected to be available for third-party leasing. Core Scientific plans to reallocate roughly 300 MW of the site's former mining capacity to support data center operations. Foundation work for the first data hall has been completed, with initial operations projected to begin in early 2027. To support the buildout, the company has acquired more than 200 acres locally and plans to raise over $4 billion, including $3.3 billion in senior secured notes and a previously secured $1 billion credit facility from Morgan Stanley. Proceeds are intended to fund data center development across Texas, Georgia, North Carolina, and Oklahoma.

U.S. Bitcoin spot ETFs posted $263 million in net outflows on April 27, according to SoSoValue Crypto data, ending a nine-session run of steady inflows. Fidelity's FBTC led the selling pressure, with $150.4 million leaving the fund. U.S. spot Ethereum ETFs also saw redemptions, recording $50.48 million in net outflows. Fidelity's FETH made up the bulk of the withdrawals at $48.43 million.

Block Inc., the fintech company led by Jack Dorsey, has published what it described as Cash App’s first-quarter proof-of-reserves report, detailing its bitcoin positions including customer assets. According to CoinDesk, Block said that as of March 31, 2026, it held 28,355 BTC valued at about $2.2 billion. The report was verified by an independent auditor and covers assets held through Block’s corporate finance function, Square, and Cash App. Block said roughly 19,357 BTC, worth around $1.5 billion, are held on behalf of customers. The company’s own bitcoin holdings total 8,997 BTC, valued at approximately $692.3 million. "People shouldn't just believe their Bitcoin exists—they should be able to verify it," the company said Monday. Block added that on-chain signatures allow anyone to independently confirm its holdings and that reserves are actively controlled rather than based solely on historical data. Proof-of-reserves reporting gained traction after the collapse of FTX, as crypto firms sought to boost transparency by showing on-chain holdings. MicroStrategy co-founder Michael Saylor has criticized the practice, saying in remarks reported in May 2025 that publishing on-chain proof of reserves is a "bad idea" that could create security risks for companies. Block is scheduled to report first-quarter earnings on May 7. For the fourth quarter of 2025, the company reported net income of $115.7 million, compared with $1.9 billion in the same period of 2024. Block shares on the New York Stock Exchange fell 0.49% to $71.28 on Monday, though the stock is up 24.9% over the past month.

Bitcoin dropped below $77,000 as the broader crypto market retreated, with total market capitalization slipping to about $2.56 trillion, according to CoinDesk. Bitcoin was down 1.4% over the past 24 hours, while Ethereum traded around $2,270 at the time of writing. The Fear & Greed Index stayed in neutral territory, pointing to limited near-term directional momentum. ETF flows appeared to be a key driver of the move. FarSide Investors data for April 27 showed spot Bitcoin ETFs recorded net outflows of roughly $263 million, led by sizable redemptions from the largest products. The reversal followed several sessions in which sustained institutional demand had helped support sentiment. Spot Ethereum ETFs also saw net outflows of about $50 million on the same day, signaling a broader pullback by institutions as part of risk management. In contrast, Solana-related ETF products posted zero trading volume, indicating little fresh capital moving into higher-risk segments. Coinglass data also showed no inflows for an XRP ETF, reinforcing a marketwide "wait-and-see" posture. Weakness extended to major altcoins, with BNB, Solana and XRP each down 1% to 2% on the day. Investors continue to weigh interest-rate expectations, inflation and geopolitical risks, leaving digital assets sensitive to shifts in global risk appetite. Analysts expect volatility to persist in the near term, particularly if ETF flows remain soft. A renewed upswing may depend on institutions returning as buyers, after playing a major role in driving gains through 2025 and early 2026. The next few trading sessions are likely to be pivotal as the market sits between consolidation and a deeper pullback. In the current environment of uncertainty and volatility, secure custody is increasingly top of mind for investors.

CoinDesk reports that Michael Saylor's Strategy has bought $255 million in bitcoin at an average price of $77,906. On Polymarket, the contract tracking whether bitcoin will print a new all-time high by June 30, 2026 is priced at 2.6% "Yes," down from 3% a day earlier. Strategy's latest purchase price sits above its reported average acquisition cost of $75,537, underscoring continued accumulation even at higher levels rather than waiting for pullbacks. Liquidity on the Polymarket contract appears extremely thin. While the 24-hour trading volume showed $843 in face value, only $26 in actual USDC changed hands, implying even small trades could materially move prices. Across maturities, the market is assigning higher odds later in the year: the September contract trades at 11% "Yes," while the December 31 contract is at 17.5% "Yes." The biggest step-up is from June to September, suggesting traders see a potential catalyst in that window. The sharpest single move was a 2-percentage-point jump that pushed September to 12%, a sign of speculative interest more than firm conviction. Why it matters: At $77,906 per coin, Strategy bought about $2,369 above its own average cost. If the June "Yes" shares are priced at $0.026 and settle at $1, the payoff would be roughly 38.5x. With liquidity so low, those implied odds can shift rapidly with minimal volume. What to watch: Markets will focus on whether other corporates or institutions follow Strategy's lead, regulatory and macro developments, and signals from key figures such as Jerome Powell and major crypto executives. Any change in the timing of Saylor's next purchase or the pace of Strategy's accumulation could move sentiment in both spot and prediction markets. API access

SoSoValue data show that U.S. spot Bitcoin ETFs posted a combined net outflow of $263 million on April 27 (ET), ending a nine-day run of net inflows. U.S. spot Ethereum ETFs also saw net redemptions, with total net outflows of $50.48 million; BlackRock's Staked ETH ETF (ETHB) was the only fund to record a net inflow.

Jack Dorsey's Block reported holding $2.2 billion worth of bitcoin as of the first quarter.

Strategy, led by Michael Saylor, purchased $255 million worth of Bitcoin at an average price of $77,906 per coin. On Polymarket, the contract pricing the chance that Bitcoin makes a new all-time high by June 30, 2026 stood at 2.6% "YES", down from 3% the prior day. ## Market reaction The buy was executed above Strategy's average acquisition price of $75,537, signaling a willingness to keep accumulating at higher levels. Liquidity in the June 30, 2026 all-time-high contract remains thin: 24-hour volume totaled $843 in face value, while only $26 in USDC actually traded, leaving odds vulnerable to small orders. Across Polymarket's term structure for Bitcoin all-time-high contracts, implied probabilities rise with time: June trades at 2.6% "YES", September at 11%, and Dec. 31 at 17.5%. The sharpest step-up from June to September points to expectations of a potential catalyst in that window. The largest single move was a two-point jump to 12% in the September market, a pattern more consistent with speculative positioning than strong conviction. ## Why it matters At $77,906 per coin, this purchase sits $2,369 above Strategy's average cost basis, underscoring continued buying rather than bargain-hunting. The June contract last priced "YES" at $0.026; a $1 settlement would imply a 38.5x return. Thin liquidity, though, makes the pricing fragile and prone to outsized swings on minimal volume. ## What to watch Key drivers include whether other corporate or institutional buyers follow Strategy's lead, regulatory headlines, macro shifts, and signals from policymakers such as Jerome Powell or major crypto executives. Any change in Strategy's pace of accumulation, including Saylor's next purchase, would be closely watched by these markets. ## API access Access prediction-market intelligence via a structured API feed.
