The Heart of the 'Artificial Sun': China Builds Largest Magnet for Fusion Reactor

On June 27, 2026, China's Institute of Plasma Physics announced the successful development and comprehensive testing of two key superconducting magnets for its "artificial sun" fusion reactor project. These magnets are crucial for containing plasma exceeding 100 million degrees Celsius within a vacuum chamber using powerful magnetic fields. The first is a D-shaped toroidal field magnet, claimed to be the world's largest for a fusion reactor. Measuring 21m long and weighing 582 tons, it has 1.3 times the volume and triple the stored energy of its counterpart in the international ITER project. Key parameters include a 98 kA operating current and 120 GJ of stored energy. Sixteen such magnets will eventually form a ring generating a central field of 6.5 Tesla to confine the plasma. Concurrently tested was a high-temperature superconducting central solenoid. It stably carries 60 kA of current and plays a critical role in inducing and sustaining the plasma current, essentially "igniting" the fusion reaction. All key technologies and materials are domestically developed, with 47 patents filed. The magnets are destined for the BEST (Burning Plasma Experimental Superconducting Tokamak) device, with assembly planned by 2027 and a demonstration of power generation targeted for around 2030. Fusion is pursued as a potential source of vast, clean energy without long-lived radioactive waste. While this marks a significant technical achievement, the article's concluding AI perspective notes the ongoing race between China's state-funded, large-scale approach and private ventures in other countries betting on compact, high-field magnets, highlighting funding sustainability as a key long-term factor.

Prediction Markets Advise Holding Positions, While Citadel Securities Forecasts Fed Rate Hike Amid Trump Pressure on Central Bank

The U.S. Federal Reserve's FOMC meeting on July 28-29 is the main focus, with markets largely expecting interest rates to hold steady at 3.50-3.75%. CME's FedWatch tool gives a 66.3% probability for no change, while prediction markets like Kalshi and Polymarket show ~73% odds for unchanged rates. However, Citadel Securities' head of macro strategy, Frank Flight, predicts a surprise 25-basis-point hike to reinforce the Fed's inflation-fighting credibility under Chair Warsch. This meeting occurs amid political pressure, as former President Trump again called for rate cuts. Persistent inflation, driven partly by energy costs, and Middle East-related oil price volatility add uncertainty. The outcome is significant for Bitcoin and risk assets, which typically see larger moves when the Fed acts against consensus expectations. An unexpected hike could strengthen the dollar and pressure crypto prices, while a hold would shift market focus to the September meeting.

Blackrock invested $11.75 million in ETHA as ether funds again outperform bitcoin funds

Institutional demand for crypto started the week unevenly. Bitcoin ETFs faced net outflows of $11.64 million, marking a third consecutive day of withdrawals, with BlackRock's IBIT and Fidelity's FBTC seeing modest outflows. In contrast, Ethereum ETFs attracted $9.23 million in inflows, led by BlackRock's ETHA fund which pulled in $11.75 million. Meanwhile, Solana and XRP ETFs saw smaller inflows of $1.03 million and $592,470 respectively, while Hyperliquid ($HYPE) ETFs continued to struggle with significant outflows of $2.89 million. The data highlights a shift in institutional capital, showing selective preference for Ethereum and certain altcoins over Bitcoin and newer tokens like HYPE.

During the Next Bull Run, Analyst Predicts XRP to Surge to $6

Crypto analyst Egrag Crypto has set a major first price target of $6.40 for XRP during the next bull market cycle. This represents a potential surge of over 500% from its recent price around $1.06. The analyst notes that XRP has finally tested a breakout from a multi-year symmetrical triangle pattern. However, he warns that the price could potentially drop below $1 to a support level near $0.88 if the breakout from this pattern fails. Before reaching the $6.40 target, Egrag Crypto outlines key resistance levels that must be overcome. First, XRP needs to break through $1.23, which could trigger a rally to $1.65. A sustained move above $1.65 is then needed to signal a rally toward the token's historical highs between $3.00 and $3.50. The bullish run to $6.40 would be confirmed with support from the 21-month Exponential Moving Average (EMA) and a stable hold above the all-time high. In such a scenario, the analyst calculates that the momentum could ultimately propel XRP as high as $30. Despite these projections, XRP's price has fallen nearly 43% since the start of 2026.

The real reason DeFi projects that survived 2022 crash are shutting down now

A wave of DeFi projects that survived the 2022 bear market and subsequent crashes are shutting down in 2026. This includes platforms like Zapper, Botanix, Step Finance, Parsec, and Odos Protocol. Data shows over half of the 101 "dead" crypto projects tracked this year are DeFi-related. Analysts point to a shift in onchain economic activity rather than a simple market downturn or industry consolidation. While total fee generation remains high, capital has rotated from classic DeFi applications toward newer, adjacent platforms like Hyperliquid, Polymarket, and pump.fun. This increased competition means more protocols are vying for a smaller slice of the classic DeFi pie. Furthermore, capital has become more discerning. Investors now prioritize sustainable yield and proven track records over short-term token incentives. Institutional capital, in particular, favors established platforms. The industry is maturing, with infrastructure consolidating around major players like Uniswap and Aave. Innovation is moving "higher up the stack," as new projects increasingly build upon these established DeFi foundations instead of trying to replace them. The next wave of growth is expected to come from embedding DeFi infrastructure into traditional fintech platforms and financial services.
