What Just Changed

Situational Awareness owns 12.4 million Class A shares of Nebius — a 5.6% stake in the Dutch AI cloud provider. Nebius stock jumped 7% on Thursday following the disclosure, per CNBC.

The stock is up 149% year-to-date.

Why Nebius, Why Now

Nebius has been stacking major deals in recent months.

In March, Nebius signed a $27 billion agreement with Meta — $12 billion in dedicated capacity and up to $15 billion in additional compute over five years, according to CNBC. In the same month, Nvidia invested $2 billion directly into Nebius, with both companies agreeing to collaborate on AI infrastructure deployment and AI factory design.

Last week, Nebius announced a $2.6 billion deal with Bloom Energy to deploy fuel cell technology for faster on-site power generation at its U.S. data centers. That deal directly addresses Europe's power cost problem — electricity prices there are significantly higher than in the U.S., and Nebius is attempting to close that gap.

The Broader Rally: Historic Numbers

The Nebius pop is happening inside a chip rally that shows extraordinary momentum.

Nasdaq's PHLX Semiconductor Sector Index — which tracks the 30 largest U.S.-traded chip companies — dropped 6.3% in March as investors panicked over hyperscaler AI spending. Then April happened. The index surged 35.2% from the start of April through late April, according to CNBC.

"The semiconductor tape we have seen this month is nothing short of historic," Bruce Bateman, chief analyst at Omdia, told CNBC. "We are talking about winning streaks not seen since the 1970s."

Micron Technology crossed the $1 trillion market cap threshold, with its high-bandwidth memory chips reportedly sold out for all of 2026, according to TradingKey. Intel had its best single trading day since 1987. Nvidia's market cap breached $5 trillion ahead of its earnings. The Nasdaq hit an intraday peak of 26,725.29 points on May 26, per TradingKey.

The Hedge: Record Put Activity

Open interest in put contracts on the VanEck Semiconductor ETF (SMH) has surged to just under 1.7 million contracts — the most ever recorded since the fund launched in 2011, according to Bloomberg data cited by CNBC. Call contracts sit at just over 500,000. That's more than a 3-to-1 ratio of puts to calls.

Implied volatility on SMH is nearing 55%, close to the highest level in over a year. Zed Francis, chief investment officer at Chicago-based Convexitas, told CNBC that rising implied vol while puts surge means traders are buying those puts, not selling them.

"People are hedging the move rather than leaning to it," Francis said. "This might be more sustainable than a boom and bust."

Don Kaufman, co-founder of TheoTrade, bought the 535/525-strike put spread in SMH expiring late August. "The squeeze has got to be ending soon," Kaufman told CNBC. "Who in their right mind would want to spend this much on jaw-dropping crap?"

Professional Positioning

Situational Awareness is making a structural bet on AI infrastructure — the physical layer of compute, power, and memory that the AI economy runs on. The record put activity in SMH reflects professional traders acknowledging that single chip stocks like Micron are trading at 105% implied volatility, making hedging through the ETF more cost-effective. That's sophisticated positioning.

The bullish momentum signals from marketshost showing NVDA, AMD, ASML, MU all flashing "Strong Buy" technical alerts are real data points — but technical momentum doesn't override macro risk. High oil prices, secondary inflation, and the fading effect of 2026 tax rebates remain factors, per TradingKey's analysis.

David Miller, senior portfolio manager at Catalyst Funds, told CNBC that sentiment has been supported by AI demand converting into real revenue growth — not just hype. A 35% monthly index move on improved sentiment still requires earnings to justify those gains.

What It Means for Regular People

If you own a broad index fund, you're already riding this wave — and already exposed if it breaks.

The professionals are bullish enough on AI infrastructure to keep buying names like Nebius. They're also buying massive amounts of downside protection, because at 55% implied volatility and 105% vol in individual names, the market is pricing in significant uncertainty in both directions.

Situational Awareness sees Nebius as the infrastructure play that survives regardless of which AI model wins. The disclosure shows exactly how big that conviction is: 12.4 million shares and a 5.6% stake. The rally is historic. The hedging is historic. Both are happening simultaneously.
