3 Top AI Stocks to Buy for the Rest of 2025

The article identifies Taiwan Semiconductor Manufacturing (TSMC), Alphabet, and AppLovin as compelling investment opportunities positioned for growth amid the AI boom. TSMC, the leading AI chip foundry with an estimated 67% market share, is projected for 21% annual earnings growth over the next 3-5 years, with its stock up 31% year-to-date. Alphabet is poised for further upside following a favorable antitrust ruling on its Chrome browser, leveraging substantial liquidity for AI investments and shareholder returns, and remains the cheapest 'Magnificent Seven' stock at 25x P/E. AppLovin, an AI-powered digital advertising platform, reported robust Q2 2025 performance with 77% year-over-year revenue growth to $1.26 billion and 164% net income increase, driving its stock up 75% YTD, despite a high valuation.

Analysis

The artificial intelligence sector continues to present distinct investment opportunities across the value chain, as highlighted by the fundamental strengths of Taiwan Semiconductor Manufacturing (TSM), Alphabet (GOOGL), and AppLovin (APP). TSM solidifies its position as a critical infrastructure provider, commanding an estimated 67% of the foundry market and serving as the primary manufacturer for leading AI chip designers. Its strategic importance is underscored by analyst projections of 21% average annual earnings growth over the next three to five years, with a current P/E ratio of 25 suggesting further upside potential despite a 31% year-to-date stock appreciation. Concurrently, Alphabet has been significantly de-risked by a favorable antitrust ruling concerning its Chrome browser, which protects its core digital advertising business that constituted 74% of H1 2025 revenue. This legal clarity, combined with a P/E of 25—the lowest among the 'Magnificent Seven'—and substantial financial power ($67 billion in free cash flow over 12 months) to fund both a $75 billion capex plan and a $70 billion share repurchase program, strengthens its investment case. In the application layer, AppLovin demonstrates exceptional hypergrowth, with its AI-powered ad platform driving a 77% year-over-year revenue increase to $1.26 billion and a 164% net income surge in its most recent quarter. However, this performance comes with significant valuation risk, as its price-to-sales ratio of 37 is more than triple its historical average of 11.

Key Decisions for Investors

• Investors should assess Taiwan Semiconductor Manufacturing for its foundational role in the AI supply chain, where its 67% market share and projected 21% annual earnings growth offer a compelling growth-at-a-reasonable-price profile.
• The favorable antitrust ruling for Alphabet can be viewed as a catalyst that reduces legal overhang, making its valuation of 25x P/E attractive given its immense free cash flow generation and aggressive capital deployment into both AI infrastructure and shareholder returns.
• While AppLovin's 77% year-over-year revenue growth is impressive, it is imperative to weigh this against its elevated price-to-sales ratio of 37, which suggests a high sensitivity to any deceleration in growth or shifts in market sentiment.
• Consider that these three companies offer distinct exposures to the AI theme: TSM as the core infrastructure, Alphabet as the mega-cap platform, and AppLovin as a high-growth application specialist, allowing for diversified strategies within the sector.
