James Comer, the chairman of the U.S. House Oversight Committee and a Republican lawmaker, has written to OpenAI CEO Sam Altman, requesting information regarding potential conflicts of interest related to personal investments and OpenAI. The investigation focuses on Altman's extensive personal investment network. Since Altman does not hold equity in OpenAI, his estimated net worth of approximately $3.5 billion primarily comes from his personal investment portfolio, which includes companies like Helion, Stripe, and Reddit.According to a previous report by The Wall Street Journal, Altman had pushed for OpenAI to invest $500 million in the fusion company Helion, while Altman himself has invested at least $375 million in the company. Comer stated that this has raised concerns about whether Altman is using OpenAI to enhance the valuation of his personally held companies. Additionally, attorneys general from states such as Florida, Montana, Nebraska, Iowa, West Virginia, and Louisiana have also written to SEC Chairman Paul Atkins, requesting an investigation into whether Altman has engaged in "self-dealing" and serious conflicts of interest.Meanwhile, Altman is set to testify in court on Tuesday and Wednesday in the case where Musk is suing OpenAI. Musk accuses Altman and OpenAI co-founders of violating the original "non-profit" commitment by shifting OpenAI to a profit-making operation. Although the conflict of interest investigation and Musk's lawsuit are independent events, Altman's personal investment issues have been raised multiple times during the trial. OpenAI board chairman Bret Taylor defended Altman in court, stating that he has been "open and transparent" regarding personal investment matters.

According to Fortune, OpenAI CEO Sam Altman shared his views at the Sequoia Capital AI Summit, noting significant generational differences in how users of different ages utilize ChatGPT. He stated that older users tend to use ChatGPT as a substitute for Google Search, while those in their twenties and thirties use it as a life advisor, and college students use it as a deeply integrated daily operating system.In the U.S., over one-third of young people aged 18 to 24 frequently use ChatGPT, leveraging its conversational memory feature for emotional advice, workplace negotiations, medical consultations, and even major life decisions. Sequoia Capital made its first investment in OpenAI in 2021, when the company was valued at $140 billion; after significant private equity financing, its current valuation has reached $852 billion.

In the first quarter of Greg Abel's tenure as CEO, Berkshire Hathaway's cash reserves surged to a record high of $397 billion. At the end of last year, the company's cash reserves had slightly decreased, but they increased significantly in the first quarter due to a net sale of $8.1 billion in stocks during the period.Additionally, Berkshire Hathaway A (BRK.A.N) reported Q1 2026 revenue of $93.675 billion, compared to $89.725 billion in the same period last year, with market expectations of $89.274 billion; net profit was $10.106 billion, compared to $4.603 billion in the same period last year, with market expectations of $11.762 billion. The fair value of fixed-income securities held by Berkshire Hathaway at the end of Q1 2026 reached $17.669 billion, compared to $17.816 billion in the same period last year.Buffett has always viewed cash as "a necessary but undesirable asset," often likening it to oxygen, which is crucial for businesses but not a good investment in itself. Buffett repeatedly emphasizes that Berkshire will never prefer holding cash equivalents over quality businesses; cash is merely a war chest waiting for "super good opportunities." When market valuations are too high and there are no attractive investment targets, he prefers to hoard cash rather than force a purchase; but once a great opportunity arises, he will deploy this ammunition without hesitation. In Buffett's view, cash can provide safe returns in a high-interest-rate environment, but in the long run, it is far less valuable than investing in excellent companies.While Berkshire's cash holdings reach a new high, despite the S&P 500 and Nasdaq indices recently hitting historical highs, there are still multiple risk hazards behind the market, and valuations are in a historically high range. Data shows that as of April, the rolling price-to-earnings ratio of the S&P 500 is about 24 times (historical average is about 16 times), and the Shiller price-to-earnings ratio (cyclically adjusted) has risen to over 37 times, at a historically high level, second only to the internet bubble period. This combination of "valuation + high expectations" means that the market has very limited room for error. Furthermore, the current rise in U.S. stocks is built on optimistic assumptions such as "AI-driven profits, falling inflation, declining interest rates, and controllable risks," and any deviation in these variables could trigger amplified shocks in the market.

Samsung Electronics' operating profit in the first quarter increased by 756.1% year-on-year, reaching 57.23 trillion won (approximately 38.5 billion USD), setting a new quarterly record. The chip business contributed the majority of the earnings, while revenue grew by 69.2% year-on-year, reaching 133.87 trillion won, and net profit increased by 474.3%, reaching 47.23 trillion won. The Device Solutions division (responsible for its semiconductor business) achieved revenue of 81.7 trillion won, with operating profit reaching 53.7 trillion won.These results far exceeded market expectations. According to data from financial data provider FnGuide, local brokerages had generally expected revenue of 117.13 trillion won and operating profit of 38.12 trillion won over the past month. Samsung Electronics' latest quarterly revenue and operating profit both surpassed the record highs set in the previous quarter (93.84 trillion won and 20.07 trillion won, respectively).

According to Jinshi reports, Federal Reserve Chairman Powell stated that the number of people who believe the likelihood of interest rate hikes is about the same as that of interest rate cuts has increased.

ZachXBT posted on platform X criticizing Sam Altman's associated project World (formerly WorldCoin), questioning its practice of obtaining biometric data from users in low-income countries in exchange for distributing WLD tokens.He also criticized the low circulation token design of WLD, stating that the related identity verification system has led to a black market for verified accounts, and questioned the token inflation mechanism and the issue of off-exchange holdings circulation.

CryptoQuant analyst MorenoDV_ tweeted that if Bitcoin can rise above and hold the $80,000 mark, this position will turn from resistance to support; conversely, if it encounters rejection and falls back, it will confirm $80,000 as a significant selling pressure area, potentially extending the adjustment period into the second quarter.Currently, the realized price for BTC ETF investors is about $76,400, which is close to the spot price (around $76,300), marking the first time since January 30 that it has approached the breakeven point; short-term holder whales have a realized price around $79,600 and are currently facing an unrealized loss of about $9.4 billion.MorenoDV_ pointed out that historically, when these trapped funds are finally released, it often triggers significant selling pressure. Bitcoin is currently fluctuating in the $76,000-$80,000 range, where $80,000 is not only an important psychological level but also a common breakeven and release threshold for these two major groups.

In a discussion about the late girl Liv Perrotto's question, she had asked whether her design "ASTEROID" could be used as SpaceX's mascot. In response, Musk said, "Ok."Perhaps stimulated by this news, the Ethereum-based meme coin ASTEROID (which launched in September 2024) briefly surpassed a market value of $160 million, currently reported at $116 million, with a 24-hour increase of over 500% and a 24-hour trading volume exceeding $77 million.It is reported that Liv Perrotto, a 15-year-old girl who passed away from cancer, had the biggest wish to meet Musk and wrote a list of questions she wanted to ask. She had previously participated in designing a zero-gravity indicator toy named "Asteroid"—a Shiba Inu figure. Her mother later publicly wrote to Musk, hoping he would consider making Asteroid the official mascot of SpaceX in accordance with Liv Perrotto's wishes. Musk responded by saying, "I will reply shortly."

The native companion asset of Bitcoin, DMT-NAT (abbreviated as NAT), has now landed on the Spider Mining Pool. Miners can simultaneously receive NAT rewards while mining BTC in the same block, achieving dual earnings and ushering in an era of dual-layer rewards in the industry.It is reported that NAT shares computing power, blocks, and addresses with BTC, allowing for simultaneous production without additional operations. This asset is produced every 10 minutes in sync with Bitcoin blocks, with approximately 386 million NAT (currently valued at about 38 USD) produced per block, corresponding to a total market value of about 38 million USD. The output will gradually decrease with block height and mining difficulty, and the code is fully open source.When the single block reward reaches 50,000 USD (market value of 50 billion USD), it can cover part of the miners' costs, thereby enhancing the overall network's computing power. Against the backdrop of Bitcoin halving, it injects new momentum for Bitcoin miners.

Investment company KKR announced that it has reached a final agreement with Samsung SDS, a blockchain and IT financial services provider under Samsung, to acquire newly issued convertible bonds worth 1.22 trillion won (approximately 820 million USD).Samsung SDS launched digital transformation experience services in 2020, including a blockchain platform, and co-developed a certificate service driven by blockchain technology with Shinhan Bank. Additionally, it serves as a technical advisor for the CBDC pilot project led by the Bank of Korea. It is reported that KKR will provide consulting services in mergers and acquisitions, capital allocation, artificial intelligence products, and global expansion, as well as accelerate the construction of artificial intelligence infrastructure.

Analyst Markus Thielen stated that the fund flow into Bitcoin ETFs has recently turned positive again and is expected to achieve net inflows for the second consecutive month, indicating an improvement in market sentiment.Data shows that the current fund flow trend is highly similar to that of the same period in 2025. At that time, the fund inflow was relatively smooth at the beginning of the year, but then there was a concentrated inflow of about $30 billion, which drove Bitcoin to continue rising in the following months.Analysis suggests that the recent fund inflow indicates that the market has gradually digested the previous selling pressure, marking the first net inflow since March, which may provide support for future market trends.

According to CoinDesk, based on data from Arkham Intelligence and The Information, SpaceX currently holds 8,285 bitcoins in its Coinbase Prime custody account, valued at approximately $603 million, while the company is projected to incur nearly $5 billion in losses for the full year of 2025.Financially, SpaceX's revenue is expected to increase to $18.5 billion in 2025, but due to the acquisition and integration of Elon Musk's artificial intelligence company xAI in February this year, costs have exceeded revenue, leading to a significant reversal from a profit of about $8 billion in 2024 to a loss of nearly $5 billion.Despite recording substantial losses, SpaceX's bitcoin holdings have remained unchanged since mid-2024, showing no signs of reduction. CoinDesk's on-chain transfer records indicate that the last significant asset movement occurred about four months ago, involving a rebalancing operation of 614 and 1,021 bitcoins between SpaceX's internal wallets. The value of the holdings peaked at over $1.6 billion during the historical high of bitcoin in October 2025.In terms of corporate bitcoin holdings, SpaceX is currently the fourth largest known corporate holder, following Strategy, Marathon Digital, and Riot Platforms.

Bloomberg senior ETF analyst Eric Balchunas stated on the X platform that as the market focuses on the launch of the Morgan Stanley Bitcoin ETF MSBT, the Bitcoin After Dark ETF (NGHT) was also launched this Wednesday. The product had a mediocre performance on its first day of trading, but trading volume significantly increased on the second day, and its future performance remains to be seen.Historical research shows that "night returns" often outperform daytime returns, but for long-term ETF investors, holding products like MSBT can cover both day and night returns, so the impact of the difference is limited. However, if NGHT sees strong inflows in the future, it may gain market recognition; conversely, it could quickly become marginalized. The Morgan Stanley Bitcoin ETF, with its channel distribution advantage, is expected to achieve great success.

According to CoinDesk, in the first quarter of 2026, institutional investors purchased a total of 69,000 bitcoins, while retail investors sold 62,000 bitcoins during the same period.
