The prediction markets have a very different view of nearterm gasoline prices than the futures market. I haven't done the full calculation with options prices, but it looks like there is probably an arbitrage opportunity. www.natesilver.net/p/gas-prices... www.wsj.com/market-data/...

Trump administration drops its appeal of court order blocking $1.2-billion UCLA settlement
The Trump administration dropped its appeal of a major higher education case in which a federal judge blocked its $1.2-billion settlement proposal to UCLA over alleged civil rights violations. But it will continue to fight the ruling on the matter in a lower court.

This paper shows that you can predict actual purchase intent (90% accuracy) by asking an off-the-shelf LLM to impersonate a customer with a demographic profile, giving it a product image & having it give its impressions, which another AI rates. No fine-tuning or training & beats classic ML methods.

On one hand: don't anthropomorphize AI. On the other: LLMs exhibit signs of gambling addiction. The more autonomy they were given, the more risks the LLMs took. They exhibit gambler's fallacy, loss-chasing, illusion of control... A cautionary note for using LLMs for investing without guardrails.
