By Alphabet stole the spotlight with a big Berkshire-backed rally, while SEBI’s clash with Jane Street kept regulatory tensions high in India.
Nvidia saw a slight wobble after Peter Thiel’s fund exited its position, even as analysts stayed upbeat ahead of earnings.
In crypto, Bitcoin dipped below $ 94,000, extending its slide as fear continues to grip the market.
A glance at the major developments on Monday.
Berkshire bet sends Alphabet soaring
Alphabet had a huge day, with its stock jumping almost 6% to hit a record high after news broke that Berkshire Hathaway had bought a $4.9 billion stake in the company.
That’s a big vote of confidence from Warren Buffett’s team, which doesn’t make tech bets all that often.
The spike also shows how excited investors are about Alphabet’s AI-powered growth plans, from the momentum behind Google Cloud to the buzz around its upcoming Gemini 3.0 model.
With the stock already up around 46% this year, Wall Street clearly sees Alphabet as one of the strongest players in the tech space right now.
Despite all the uncertainty in the broader market, Berkshire’s move really underscores just how solid Alphabet’s fundamentals look.
SEBI pushes back on Jane Street
India’s market regulator, SEBI, is expected to tell a court this week that it doesn’t see any reason to hand over more data or documents to Jane Street, the US trading firm it temporarily barred back in July over alleged index manipulation.
Jane Street has been pushing for additional information as part of its appeal, but SEBI reportedly views the request as more of a stalling tactic and believes sharing those details could interfere with the ongoing investigation.
Jane Street has already paid a penalty to get back into the market, though it still disputes the allegations.
SEBI’s probe into the firm’s trading activity from 2023 through 2025 is still underway, and the outcome could have broader implications for the market going forward.
Nvidia slips after Thiel sell-off
Nvidia’s stock took a bit of a hit after news surfaced that Peter Thiel’s hedge fund, Thiel Macro LLC, completely sold off its Nvidia position, all 537,742 shares, worth close to $100 million.
The timing raised some eyebrows since it comes right before Nvidia’s much-anticipated earnings report, which many expect to show strong revenue thanks to booming demand for AI chips and cloud computing.
Even with Thiel stepping out and the stock dipping slightly, Wall Street isn’t sounding any alarms. Analysts are still largely bullish, keeping their buy ratings and targeting prices around $250.
Thiel’s move looks more like a portfolio reshuffle driven by concerns over stretched AI valuations rather than a vote of no confidence in Nvidia.
In other words, it’s a cautious move, but not necessarily a bearish one about Nvidia’s long-term future.
Bitcoin drops below $94K
Bitcoin slipped below $94,000, its lowest level since May 2025, as the entire crypto market faced another round of selling.
The drop lines up with Bitcoin’s usual 4-year cycle after the April 2024 halving, and analysts at Bernstein say part of this slide is basically a “self-fulfilling prophecy.”
Traders expect weakness during this phase, so they sell, and the price falls even more.
The pullback has erased about 25% of Bitcoin’s gains since its October peak near $126,000, driven by softer demand, big sell-offs from long-term holders, and steady outflows from Bitcoin ETFs.
Meanwhile, the Crypto Fear & Greed Index is still stuck in “extreme fear,” which doesn’t help; it just adds to the volatility and keeps the market on edge.
