In this article, we will discuss the 10 Best Stocks to Buy According to Billionaire Ken Griffin.

Billionaire Ken Griffin is one of Wall Street’s most influential money managers. Over the years, he has posted strong returns across tactical trading, equities and alternative strategies. In 2025, his firm Citadel’s flagship hedge fund, Wellington, rose 10.2%, compared with the S&P 500’s 18% gain over the same period. Why the underperformance? Wellington fund follows a diversified, multi-asset strategy. This approach lowers risk but also limits upside. While the stock market surged amid AI-driven euphoria, Wellington’s risk-averse positioning meant it didn’t capture the full gains. That strategy is proving prudent in 2026, as the war in the Middle East is creating market volatility and testing riskier investments.

Citadel’s Global Fixed Income Fund fell 8.2% in March, according to a Bloomberg report, amid disruption in the global markets due to the ongoing Middle East conflict. However, Citadel’s Wellington fund, which is more diversified, only fell 1.9% in March and is up about 1% so far this year, while the S&P 500 is down 4%.

In an October interview with Bloomberg, Griffin warned that the market might be overlooking inflation-related risks and signs of brewing turmoil. He emphasized that market crashes often begin without warning, and there is only so long the market can ignore such signals. When a crash occurs, it can happen quickly and unpredictably, the billionaire warned. He said at the time that stocks were in a “deep” bull market, and there was a lot of FOMO that was making everyone ignore the red flags.

“When the market chooses to change its mind, the correction can be extraordinarily quick and extraordinarily painful,” Griffin said. “In 87, we didn’t have a catalyst. No matter how exuberant the market may be at any moment in time, when you’re late, that cycle, that cycle can shift in the blink of an eye.”

Major clients like Nvidia, Apple, and Broadcom are reportedly entering agreements to secure capacity 3-4 years in advance.

Taiwan Semiconductor Manufacturing Company (NYSE:TSM) has raised its capital expenditure forecast to $56 billion for 2026 and plans $165 billion in US investments over the next few years. Its moat and high-capacity production make it an attractive buy for the long term despite its gains.  The stock trades at a forward P/E of 20x, slightly above its 5-year average of 19x.

9. Alphabet (NASDAQ:GOOGL)

Ken Griffin’s Stake Value: $913,187,829

Alphabet (NASDAQ:GOOGL) shares are down about 7% so far this year and some believe now is the right time to pile into the stock to benefit from its long-term growth catalysts. In the recently reported quarter, Alphabet (NASDAQ:GOOGL) revenue rose 18% rose year over year, while search grew 17% despite AI-related threats.  Google Cloud was up 48% YoY, and had a backlog of $240 billion, signaling strong enterprise demand for AI infrastructure.

But let’s not ignore the elephant in the room. How can Alphabet (NASDAQ:GOOGL) save its search and ads business in the long term from AI-related cannibalization effects? The Gemini AI ecosystem is the answer.  Gemini reached more than 750 million monthly active users and Alphabet’s (NASDAQ:GOOGL) AI models now process over 10 billion tokens per minute via API usage. Google is testing ads inside AI-generated answers and placing sponsored results below AI responses. It’s using AI to better match commercial intent, with early data showing engagement rates similar to traditional search ads. AI queries are typically 3× longer and more detailed, allowing Google to understand user intent more precisely and serve higher-quality, higher-priced ads, especially for shopping, travel, finance, and local services where monetization remains strongest. GOOG ranks ninth in our list of the best stocks to buy now, according to billionaire Ken Griffin.

Montaka Global Investments stated the following regarding Alphabet Inc. (NASDAQ:GOOGL) in its Q4 2025 investor letter:

Alphabet Inc. (NASDAQ:GOOGL) has large, valuable core businesses that are clear beneficiaries of larger and more powerful AI models. Therefore, any ‘excess’ capacity that might materialise from the data centre buildout over the coming years will more rapidly be absorbed by their internal needs. So overall, we see the existence of large, tech/AI-enabled non-cloud businesses attached to the hyperscalers, not as a risk, but as a major strategic advantage (Click here to see the full text).

8. Morgan Stanley (NYSE:MS)

Ken Griffin’s Stake Value: $916,479,807

Morgan Stanley (NYSE:MS) ranks 8th in our list of the best stocks to buy now, according to billionaire Ken Griffin. Morgan Stanley’s (NYSE:MS) wealth management business is its key catalyst to buy the stock today. Why? Wealth management produces recurring revenue and grows with the broader economy despite short-term volatility. Morgan Stanley (NYSE:MS) currently sits at $9.3 trillion in total client assets. In just the last quarter of 2025, net new assets surged 116% year over year to $122 billion, driven by a funnel that pulls clients in through E*Trade and workplace stock plans, then migrates them into advisor-managed relationships.

Investment banking is also a sound catalyst for the stock because the Fed is expected to keep cutting rates in the long term, despite the short-term pause or war-related uncertainty. Deals were frozen for two years when rates were high. With easing rates and deregulation back, the M&A pipeline that’s been building pressure like a coiled spring is starting to release.

Baron Financials ETF stated the following regarding Morgan Stanley (NYSE:MS) in its fourth quarter 2025 investor letter:

“During the quarter, the Fund invested in Morgan Stanley (NYSE:MS), a leading global investment bank and wealth management firm. Morgan Stanley has successfully diversified its business beyond cyclical banking and trading fees into more recurring wealth and investment management. These businesses collectively oversee $9.3 trillion in client assets that generate predictable, capital light revenue that grows from inflows and market appreciation. Morgan Stanley has a unique client acquisition model that includes financial advisors, self-directed accounts, and workplace accounts, providing multiple avenues to serve clients. In 2025, the company amassed over $350 billion in net new assets, with a 7% net inflow rate in the fourth quarter. These businesses provide a durable base of revenue and earnings for Morgan Stanley even when banking activity is slow. At the same time, Morgan Stanley remains a top three global investment bank, enabling the firm to generate considerably higher earnings during periods of strength in the capital markets.

Morgan Stanley benefits from numerous competitive advantages. It has a leading brand in banking and wealth management, long held customer relationships, and access to premier industry talent. Its unique customer acquisition model gives Morgan Stanley a strong relationship with clients earlier in their wealth lifecycle and the ability to grow with clients as they build wealth. As Morgan Stanley grows revenues, we expect continued margin expansion from operating leverage and efficiencies from the broader usage of AI. The company has significant excess capital, which could be used to invest in the business or returned to shareholders, especially as capital requirements ease under a more business-friendly administration…” (Click here to read the full text)
