It has been a big year for executives and investors at 15 companies in the S&P 500 ^GSPC https://finance.yahoo.com/quote/^GSPC/ , and it's all because of one factor. You guessed it: the Great AI Boom. There are now 15 companies in the S&P 500 up 100% or more this year see chart below , per Yahoo Finance analysis. Sandisk SNDK https://finance.yahoo.com/quote/SNDK/ is leading the way with an almost 600% gain on the year amid strong demand for its memory chips at ever higher prices. The list is interesting for several reasons. First of all, chip king Nvidia NVDA https://finance.yahoo.com/quote/NVDA/ isn't on the list, as its stock is "only" up 18% year to date. Second, on the list are old tech giants that have pivoted hard to partaking in the AI infrastructure build-out — see Dell DELL https://finance.yahoo.com/quote/DELL/ , Intel INTC https://finance.yahoo.com/quote/INTC/ , and Hewlett Packard Enterprise HPE https://finance.yahoo.com/quote/HPE/ . Finally, the list is a sign that the AI trade is broadening beyond hyperscalers like Amazon AMZN https://finance.yahoo.com/quote/AMZN/ and the aforementioned AI chip leader Nvidia. Marathon Petroleum MPC https://finance.yahoo.com/quote/MPC/ and Valero VLO https://finance.yahoo.com/quote/VLO/ are front and center here. If you don't think the many AI data centers being built in this country need a lot of fuel, well, then you are seriously missing a screw. To be sure, this has been another impressive year on the AI front. Nvidia alone hit an all-time high of $236 on May 14, per Yahoo Finance AlphaSpace https://finance.yahoo.com/about/promos/gold/alphaspace?100003557 data. That briefly made CEO Jensen Huang's company the most valuable enterprise on earth before a brutal summer sell-off wiped out more than $1 trillion in market cap and sent the stock back into the $190s. The stock has since rallied back to near record highs. The SpaceX SPCX https://finance.yahoo.com/quote/SPCX/ IPO raised a record $86 billion in June and minted CEO Elon Musk as the world's first trillionaire on the strength of AI-driven Starlink and data center revenue — before the stock plunged back to some form of reality. Microsoft MSFT https://finance.yahoo.com/quote/MSFT/ has committed $190 billion in capital expenditures for this year, Amazon has guided to $200 billion, Google GOOG https://finance.yahoo.com/quote/GOOG/ , GOOGL https://finance.yahoo.com/quote/GOOGL/ to $175 billion, and Meta META https://finance.yahoo.com/quote/META/ to $145 billion. This is a combined $700 billion-plus spending pledge from four tech beasts aiming to dominate the future of AI.
