It’s Day 6 of the Government Shutdown of 2025, and even as our government grinds to a halt, the Vanguard S&P 500 ETF (NYSEMKT: VOO) keeps grinding higher. The ETF is up 0.3% in early trading.
What’s keeping the market moving today? Well, with the government shut down, we have no official economic news to report. Instead, what we do have is quite a bit of moving and shaking in the corporate world.
In banking today, regional bank Fifth Third (Nasdaq: FITB) says it will buy rival Comerica (NYSE: CMA) in a $10.9 billion, all-stock transaction. If the merger goes through it will create America’s ninth largest bank. Fifth Third stock is up 1.5% on the news, and Comerica shares are up more than 17%.
Because Fifth Third is an S&P 500 component company, and Comerica is not (yet), though, this merger announcement is going to actually hurt, not help, the Vanguard S&P 500 ETF today.
And in AI news, privately-held OpenAI is teaming up with S&P 500 component company Advanced Micro Devices (Nasdaq: AMD) in a different way. Every hungry for more artificial intelligence computer chips, OpenAI has struck a deal to buy 6 gigawatt-hours’ worth of chips from AMD. In return for OpenAI’s business, AMD will grant the AI giant warrants to acquire up to 160 million shares of AMD stock (that’s about 10% of the company).
Yes, strange as it sounds, you read that right: OpenAI will give AMD money, and in return it will get both chips and stock in AMD. In fact, the stock may be more valuable to OpenAI than the chips. AMD shares are up more than 31% on the news.
