# T1 Energy spikes on record call buying after Situational Awareness reveals 3.6% stake

T1 Energy is soaring after a 13F filing released this morning showed Situational Awareness held a 3.6% position in the solar and battery storage company at the end of Q1.

The position makes the hedge fund one of the 10 biggest owners of T1, according to data compiled by Bloomberg.

Situational Awareness has become a closely followed fund because of how well it’s done in the AI era and who it’s run by: former OpenAI researcher Leopold Aschenbrenner, who’s only in his mid-20s!

(In fact, there was much consternation across X on Friday that the fund’s 13F wasn’t released ahead of the weekend.)

Call volumes in T1 are absolutely exploding as traders look to play follow-the-Leopold: they’re running at 52,501 less than 90 minutes into the trading day, already a one-day record for the stock.
