Because artificial intelligence (AI), that's why.</p> <p>Citing &#34;greater regulatory clarity,&#34; says Citi, Alphabet says it will release new products more quickly than in the past, building on its dominant position in internet advertising. In particular, Citi's looking to see Alphabet roll out its Gemini AI product across all the company's advertising and cloud businesses, capitalizing on its investments in AI. </p>  <h2>Is Alphabet stock a buy?</h2> <p>Investors had better hope Citi is right, because the investments that Alphabet has made in artificial investments have been truly massive -- and very expensive.</p> <p>According to data from S&amp;P Global Market Intelligence, since OpenAI released ChatGPT in late 2022, Alphabet's capital spending (on chips and server farms and other AI infrastructure, primarily) has more than doubled. Over the last 12 months, Alphabet's spent a staggering $67 billion on capital expenditures, such that today, roughly half the company's operating cash flow is immediately consumed by capex.</p> <p>Result: Free cash flow at the company grew just 11% <em>total </em>over the last three years.</p> <p>Right now, Alphabet may be a leading AI company. I won't argue that. But it's hard to call Alphabet a growth stock anymore, and until that changes, I'm not at all certain Alphabet stock is a buy.</p>                                                                            </div>

<p>Alphabet's stock surged 3% today, reaching a market cap of $3 trillion, following Citigroup's price target increase to $280 per share, a 24% rise. The boost is attributed to anticipated advancements in AI, particularly the rollout of the Gemini AI product. However, despite significant investments in AI infrastructure, concerns remain about Alphabet's growth potential, as capital expenditures have consumed much of its operating cash flow, leading to only an 11% increase in free cash flow over three years.</p>
