Investing.com -- Investors are heading into a busy week with U.S. inflation data and fresh corporate earnings likely to shape market sentiment, while developments at major companies and a potential shift in Washington’s approach to artificial intelligence add to the agenda. Berkshire Hathaway’s latest results highlighted the strength of its cash position despite weaker operating earnings, while Binance announced a finance leadership change days after a major cryptocurrency theft.

As of 0342 ET, U.S. S&P 500 Futures rose 0.35%, while the tech-heavy Nasdaq 100 Futures fell 0.3%. Dow Jones Futures climbed 0.6%. Here are five things to know before markets open:

1. Questions surround Nvidia CEO Jensen Huang following unverified allegations A claim circulating about Nvidia Chief Executive Jensen Huang has alleged that he admitted to an affair with a businesswoman suspected by U.S. intelligence of having links to China. The claim also alleges that Nvidia’s board has launched an independent investigation.

However, these allegations have not been independently established in the information provided. They should not be reported as fact without confirmation from credible sources, including Nvidia and the individuals concerned.

Any verified development involving Nvidia’s leadership could attract investor attention given the company’s central role in the global AI industry. However, investors should distinguish substantiated corporate disclosures from unverified personal allegations. Nvidia’s Frankfurt-listed shares opened 6% lower.

2. Binance finance chief departs after $6.3 billion crypto theft Binance Chief Financial Officer Kaiser Ng is leaving the world’s largest cryptocurrency exchange to pursue another venture, the company said on Saturday, days after hackers reportedly stole $6.3 billion in cryptocurrency in a major security breach.

Binance Co-CEO Yi He said Ng had decided to leave after more than five years at the company, adding that a transition plan had been in place for the past six months. Justin Yek, a former vice-president of finance at Airwallex, will take over as CFO.

The leadership change comes just over a week after Binance disclosed that hackers had carried out a sophisticated attack that began months earlier, compromising employees’ computers. The exchange said the breach, which unfolded on October 29, involved malware hidden in software downloads and fraudulent recruitment efforts targeting engineers.

The FBI has attributed the theft to a North Korean hacking group, an allegation Pyongyang has denied. Binance has said it will fully reimburse affected customers.

The timing of the CFO transition could intensify scrutiny of Binance’s financial controls and risk management, even though the company says the departure had been planned. The incident also highlights the cybersecurity risks facing cryptocurrency exchanges and the potential impact of major breaches on investor confidence.

3. Berkshire operating earnings fall as cash reserves hit record Berkshire Hathaway reported a 5.8% decline in third-quarter operating earnings on Saturday, as weaker insurance results weighed on the conglomerate’s performance.

Operating profit fell to $12.7 billion from $13.48 billion a year earlier, according to a regulatory filing. The measure is closely watched because Warren Buffett considers it a better indicator of the company’s underlying performance than net income, which can be affected by unrealized gains and losses on investments.

Despite the decline in operating earnings, Berkshire’s cash holdings climbed to a record $377.4 billion. The conglomerate also stepped up its share repurchases, buying back approximately $9.6 billion of its own stock during the quarter.

Berkshire’s growing cash pile suggests the company is maintaining substantial financial flexibility, even as it increases buybacks. The combination of record liquidity and elevated equity valuations may also offer investors insight into how the conglomerate is approaching investment opportunities and capital allocation.

4. U.S. inflation data and technology earnings take centre stage Investors will turn their attention to Tuesday’s U.S. consumer price index report, one of the most closely watched measures of inflation and an important input for expectations about the Federal Reserve’s interest-rate outlook.

The report could offer fresh clues on whether price pressures are easing or remaining persistent, potentially influencing Treasury yields, the dollar and expectations for future monetary policy.

The corporate earnings calendar will also feature several technology companies, with CoreWeave, Applied Materials and Cisco Systems scheduled to report.

A hotter-than-expected inflation reading could reinforce expectations that interest rates will remain elevated for longer, potentially weighing on stocks, particularly growth-oriented technology shares. Meanwhile, earnings from companies exposed to cloud computing, semiconductors and networking could offer further insight into the strength of AI-related investment.

5. Democrats plan push for tougher AI and data-center rules Democrats are preparing a series of legislative proposals targeting artificial intelligence systems and data-center development when they take control of Congress in January, according to lawmakers, congressional aides and advocates.

The proposed measures would represent a shift from the Republican-led Congress, which has largely prioritised promoting AI development rather than imposing restrictions on the technology.

Democrats are considering bills to protect consumers from higher electricity costs linked to data-center demand, require independent testing of advanced AI systems and clarify when AI companies could be held liable for harm caused by their products.

However, the proposals could face significant obstacles while Republican President Donald Trump remains in the White House. Trump has repeatedly opposed calls for mandatory federal rules governing AI.

The proposals could increase regulatory uncertainty for AI developers and companies investing heavily in data-center infrastructure. Potential rules on electricity costs, safety testing and liability could also affect the economics of building and operating AI systems, making the policy debate an important risk for the sector.
