      OpenAI Earns About $50 Billion A Year. It Has Promised Oracle More Than $300 Billion

      $Oracle(ORCL)$   Mathematical Money | October 11, 2026 $ORCL$ fell 5.5% on Wednesday and then took 4.2% of it back on Thursday, finishing the week down about half a percent. If you only looked at Friday's close you'd think nothing happened. Something did happen, and it wasn't really about the number everyone reported. The reaction was pointing at a genuine problem and aiming at the wrong figure entirely. What the news actually said The Financial Times reported that OpenAI told investors its annualised revenue was approaching $50 billion at the end of September, against a $70 billion figure that had been circulating. A $20 billion gap, roughly 30% of the headline. Here's the part that got lost in the reaction. That gap wasn't lost busines

      Haha. Self praise. But ok, there's always two sides of it, some truth and some blown up.

      I Collected 49 Cents To Buy MARA At $12. On Friday It Closed At $9.65

      $MARA Holdings(MARA)$   Mathematical Money | October 11, 2026 $MARA$ closed Friday at $9.65, down 14.1% on the week from $11.23 and through $10 for the first time this cycle. It was an ugly five sessions for a stock that had already had a few of those. I'd been short puts into that expiry at the $12 and $11.50 strikes, sold on 18 September for 49 cents and 53 cents a contract. Both finished in the money on Friday, so the shares were assigned to me. I said in advance that I'd report which way it went, so here it is, with the arithmetic done per share because that's the only way to see it clearly. What it actually cost The premium reduces what I paid. On the $12 strike my effective purchase price is $11.51, and on the $11.50 strike it's $1

      $MARA 20261030 11.5 CALL$ One of the fastest drawdown i ever had. 13 days of down in one counter adding up to more than 30% drop in the stock price.  Most of the short calls are below my stock average price now but just purely for extracting premium (income). Cant do much, not gonna act like I could predict where the market wants this to go. Can only manage the situation.

      $IBIT 20261023 47.0 PUT$ Was supposed to be a pair with the ibit short. Closed that earlier and was anticipating a bigger move tonight. It seems muted tonight. Will close this position since the pairing is not around anymore.
