Oklo surges amid heavy activity in call options expiring today

The most valuable pre-revenues company listed in the US, nuclear energy company Oklo, is up double digits on Friday amid heavy call options demand.

Call volumes of 74,230 have already outstripped the 10-day average for a full session an hour into the trading day, and the top three contracts traded are all in options that expire today with strike prices of $150, $145, and $160.

The first two contracts have jumped from out of the money to in the money amid the surge. Volumes transacted on the “ask” side (the lowest price a seller is willing to accept) are running more than 2x higher than on the “bid” side (the highest price a buyer is willing to pay), indicating motivated buyers in the C$150s, the most active contract.

Overall, options activity is firmly tilted to the bull side, with more than two calls trading for every put:

Nuclear energy companies have emerged as retail trader favorites as the power-hungry AI boom continues.

“A new $350 billion US nuclear build cycle could raise capacity 60% by 2050, sparking a renaissance to meet surging energy demand from AI and data centers,” wrote Bloomberg Intelligence senior analysts Rob Barnett and Scott Levine. “Energized by bipartisan policy support, the nuclear industry is positioned as a critical solution for securing and decarbonizing America’s power grid for the AI era.”

Michael Burry flags “troubling” jump in Nvidia’s supply commitments

“The Big Short” investor Michael Burry — famous for betting against the 2008 housing bubble — just warned of a major risk in Nvidia’s latest annual report, pointing to a sixfold surge in purchase obligations over the past year.

In a Substack post Thursday, Burry called the increase from $16.1 billion to $95.2 billion in just 12 months “troubling,” noting that Nvidia has been forced to place noncancelable purchase orders well before knowing the final demand for its AI chips. The surge is partly tied to supplier TSMC requiring longer-term contracts, he added.

Vistra beats Q4 earnings expectations for adjusted EBITDA, but dips on income decline

Power provider Vistra, a key player in the AI energy trade, reported better-than-expected adjusted earnings results early Thursday, but shares dipped in early trading as Q4 net income dropped.

The Texas-based company, which supplies nuclear- and natural gas-fueled power to wholesale and retail markets, reported:

Net income of $233 million, a decline of 52% from Q4 2024.
Adjusted EBITDA from ongoing operations of $1.74 billion vs. the $1.71 billion expected by Wall Street analysts.
Vistra maintained previously issued guidance for full-year EBITDA from ongoing operations and adjusted free cash flow from ongoing operations.

Vistra shares soared 258% in 2024 amid a flurry of excitement over the AI energy boom. Last year was more muted, with the stock rising 17%. So far in 2026, shares were up roughly 9% before the report.

Sandisk rises on partnership with SK Hynix to standardize memory chip architecture tailored for AI data centers

Sandisk is up 3% in premarket trading on Thursday after it began its global standardization strategy of high-bandwidth flash (HBF) memory solutions with SK Hynix.

SK Hynix commented in a press release on Thursday that “by making HBF an industry standard, together with Sandisk, we will lay the foundation for the entire AI ecosystem to grow together,” adding that the companies will set up a dedicated workstream to work on the standardization under the Open Compute Project, the world’s largest organization dealing with data center technologies.

First debuted last February, Sandisk’s HBF technology lies in between ultrafast high-bandwidth memory (HBM) and high-capacity SSDs. That is, these have more storage capacity than HBMs, but are still fast enough to be utilized in AI inferencing (albeit not as quick as HBM).

Sandisk has previously argued that this hybrid architecture is central to AI services that need user applications but require a significant amount of fast interconnect between GPUs. The latest announcement also notes that HBF technology is expected to be more cost-efficient compared to alternatives of similar scale.

The launch, which was shared in an kickoff event on Thursday evening, starts SK Hynix and Sandisk’s workflow, which was announced when the two companies signed a memorandum of understanding “to standardize the specification, define technology requirements and explore the creation of a technology ecosystem” last August, per Sandisk’s press release at the time. Ultimately, by collaborating with SK Hynix, one of the three key HBM suppliers, to standardize and commercialize the technology, Sandisk is manufacturing somewhat of a first-mover advantage to offer the system-level “AI-optimized memory architecture” required for AI inference markets, rather than focusing on the performance of a single chip element.
