Why did Michael Burry buy Microsoft stock? — Software Sector Valuation Realities

Burry’s Bullish Shift in 2026

Michael Burry, the renowned investor famous for his "Big Short" during the 2008 housing crisis, has recently made headlines by initiating a significant long position in Microsoft (MSFT). According to disclosures made via his Substack in April 2026, Burry has pivoted from his previously cautious stance on Big Tech to a decidedly bullish outlook on the software sector. This move is particularly notable because it comes at a time when many investors have been wary of the high capital expenditure (capex) associated with Artificial Intelligence (AI) development.

Burry’s entry into Microsoft was timed during a period of sector-wide volatility. In late April 2026, Microsoft shares were trading in the $415–$416 range. While the broader market was reacting to fluctuations in the semiconductor industry, Burry identified what he termed "reflexive market dynamics"—a situation where the market sells off based on momentum and fear rather than a deterioration of company fundamentals. By going long on Microsoft, Burry is signaling that the intrinsic value of the company’s diversified business model outweighs the temporary noise of the stock market.

Traditional Brokerage and Market Access

For many global investors, following the moves of institutional giants like Michael Burry presents significant structural challenges. Traditional brokerage applications often involve high entry barriers, including geographic restrictions, lengthy identity verification processes, and complex funding bottlenecks. These frictions can prevent retail participants from reacting quickly to market shifts or accessing specific US-listed equities due to local regulatory hurdles or high transaction costs.

As the financial landscape evolves, Web3 infrastructure has introduced a more streamlined alternative through tokenized equities. This modern asset class allows participants to gain price exposure to major US corporations via cryptographic representations on the blockchain. Secure execution infrastructure, such as the WEEX Exchange, provides the foundational framework for analyzing these asset movements. Furthermore, integrated asset hubs like the WEEX TradFi interface enable users to monitor real-time order flows and interact with tokenized representations of traditional equities under a unified environment, bypassing many of the legacy frictions found in old-world banking systems.

The Core Investment Thesis

Burry’s decision to buy Microsoft is rooted in a belief that the recent sell-off in software stocks was "overdone." While he had previously expressed concerns regarding aggressive accounting related to AI capex, his 2026 thesis focuses on the relative value found in Microsoft’s diversified revenue streams. Unlike pure-play AI companies that may lack a proven monetization path, Microsoft possesses a robust ecosystem that spans cloud computing, enterprise software, and consumer applications.

Diversification and Azure Growth

A primary driver for Burry’s confidence is the continued dominance of Azure. As of mid-2026, Azure has maintained a growth rate of approximately 40%, fueled by the integration of AI services into cloud infrastructure. This high-margin software and cloud business provides a "moat" that protects the company during economic downturns. Burry views the combination of Azure, the Office 365 suite, and deep AI integration as a resilient model that the market has undervalued during the recent tech rotation.

Leveraged Bets via LEAPs

Interestingly, Burry did not just buy common stock; he also utilized long-dated derivative strategies. Reports from June 2026 indicate that Burry purchased December 2028 LEAP (Long-Term Equity Anticipation Securities) call options with a strike price of $700. This is a highly leveraged bet, suggesting he believes Microsoft shares could nearly double from their current levels within the next two and a half years. By choosing a $700 strike price, Burry is positioning for a massive expansion in Microsoft’s valuation as AI revenue—which recently saw a 123% increase—begins to fully hit the bottom line.

Broader Software Sector Confidence

Microsoft is not the only name in Burry’s 2026 software portfolio. His recent filings show a broader rotation out of "crowded" hardware and semiconductor names into beaten-down software platforms. This suggests a belief that the "picks and shovels" phase of the AI boom (hardware) is maturing, and the value is now shifting to the software layer that utilizes that hardware.

Company Ticker	Sector Focus	Burry’s Rationale (2026)
MSFT (Microsoft)	Cloud & Enterprise SW	Diversified model; AI integration value
ADBE (Adobe)	Creative Software	Recovery from overdone sector sell-off
PYPL (PayPal)	FinTech / Platforms	Value play in beaten-down platform stocks
MSCI (MSCI Inc.)	Financial Data	Fundamental strength vs. market reflexivity

Risks and Market Impact

While Burry’s track record is legendary, his 2026 Microsoft bet is not without risk. The use of LEAP options, while offering high upside, carries the risk of a 100% loss if the stock fails to reach the strike price by the expiration date in late 2028. Furthermore, the tech sector remains sensitive to interest rate changes and global regulatory scrutiny regarding AI ethics and data privacy.

However, the immediate impact of Burry’s disclosure was a notable shift in market sentiment. Following the news of his position, there was a visible rotation where the Dow Jones Industrial Average showed strength while the tech-heavy NASDAQ lagged, as investors moved capital out of overextended semiconductor stocks and into the software names Burry highlighted. This "Burry Effect" helped stabilize the software sector in the second quarter of 2026.

Accounting and Capex Concerns

It is important to note that Burry’s move into Microsoft represents a change in perspective. Earlier, he had criticized the aggressive nature of AI-related capital expenditures. His current long position suggests he believes the market has now priced in those concerns, or that the revenue growth from AI is finally justifying the massive spending. With AI revenue growing at triple-digit rates, the fundamental "math" of the investment has shifted in favor of the bulls.

Long-Term Valuation Targets

By targeting a $700 price point through his options, Burry is looking past the short-term "choppy" tape of 2026. He is betting on a multi-year cycle where Microsoft becomes the primary gateway for enterprise AI. For retail investors, while following Burry into complex options can be dangerous, his move serves as a signal that one of the world's most skeptical value investors now sees deep value in the world's largest software company.
