Why are so many companies splitting their stock in 2026? We examine the mechanics, the post-split performance record, and which names could be next, including Meta and Microsoft.

Key Highlights

  • Stock splits are clustering across U.S. markets in spring 2026, spanning five unrelated sectors.
  • 2024 recorded 168 split announcements in its first half — the highest in a decade; 2025 saw a sharp contraction.
  • Booking Holdings, Carvana, KLA, and five Vanguard ETFs all split within a six-week window.
  • Post-split data is clear: Alphabet up 250%, Netflix down 20% — fundamentals decide outcomes, not mechanics.
  • Meta, Microsoft, Costco, and MercadoLibre are the four names most likely to act next.

A Concentrated Wave Across Unrelated Sectors

Within six weeks in the spring of 2026, U.S. markets witnessed an unusual clustering of split announcements across structurally unrelated industries. Booking Holdings (Nasdaq: BKNG) completed a 25-for-1 split on April 6, reducing its share price from approximately $4,117 to around $170. Five Vanguard ETFs then split simultaneously on April 21: the Vanguard Information Technology ETF (NYSEARCA: VGT) at 8-for-1, the Vanguard Growth ETF (NYSEARCA: VUG) at 6-for-1, the Vanguard Mid-Cap ETF (NYSEARCA: VO) at 4-for-1, the Vanguard S&Amp;P 500 Growth ETF (NYSEARCA: VOOG) at 6-for-1, and the Vanguard Mega Cap Growth ETF (NYSEARCA: MGK) at 5-for-1. Carvana (NYSE: CVNA) executed its first-ever forward split, a 5-for-1, on May 7, bringing a share price of approximately $400 down to roughly $80. That same day, KLA Corporation's (NASDAQ: KLAC) board approved a 10-for-1 forward split effective after market close on June 11, with split-adjusted trading commencing June 12.

The breadth of activity across travel, used-car retail, semiconductor equipment, and passive fund management reflects a common structural condition. Sustained price appreciation across sectors had pushed nominal share prices to levels where boards and corporate governance teams increasingly concluded that Liquidity constraints and reduced retail participation were becoming material concerns.

What a Split Does and Does Not Do

A forward split multiplies outstanding shares by the split ratio and divides the per-share price by the same Factor. A Shareholder holding one share at $1,000 in a 10-for-1 split holds ten shares at $100. Total portfolio value, Market Capitalisation, Earnings power, and competitive positioning are all unchanged.

The primary rationale is accessibility. Booking Holdings' pre-split price above $4,100 created genuine friction for investors without access to fractional shares. At that level, a single share represented a disproportionate allocation for most retail portfolios. The split did not make the Business more valuable; it made the ownership unit more manageable.

A secondary benefit is market microstructure. As share prices rise substantially, the spread between bid and ask prices tends to widen. Vanguard cited this explicitly when announcing its five ETF splits in March 2026, noting that the primary rationale was keeping share prices within accessible trading ranges while improving bid-ask efficiency. For ETFs with hundreds of billions in Assets under management, tighter spreads translate into material cost savings for investors at scale.

What splits do not do is alter the underlying risk-return proposition. A structurally weak business at a lower nominal price post-split remains a structurally weak business. The split is a symptom of prior price appreciation, not a mechanism for future returns.

The 2024 Surge, the 2025 Contraction, and the 2026 Recovery

The current wave sits within a clearly identifiable multi-year cycle. The first half of 2024 recorded 168 split announcements, the highest for any six-month period in over a decade, driven by high-profile actions from Nvidia (NASDAQ: NVDA) (10-for-1), Broadcom (NASDAQ: AVGO) (10-for-1), Chipotle (NYSE: CMG) (50-for-1), and Walmart (NYSE: WMT) (3-for-1) among others. That momentum decelerated sharply through 2025. Despite major stocks climbing to record nominal levels, including Netflix (NASDAQ: NFLX) above $1,200, Meta (NASDAQ: META) above $760, and AutoZone (NYSE: AZO) above $4,200, significant split activity among large-caps was absent for most of the year. Netflix (10-for-1), Interactive Brokers (NASDAQ: IBKR) (4-for-1), and O'Reilly Automotive (NASDAQ: ORLY) (15-for-1) completed splits, but none generated the market-wide attention that the 2024 cohort had produced.

The 2025 pause created pent-up pressure. When Booking Holdings announced its 25-for-1 split in February 2026, the scale of the ratio amplified the signal. A company allowing its share price to reach $4,117 before acting was, in effect, demonstrating the degree to which split decisions are discretionary. The announcement likely accelerated board-level reviews at other high-priced names, contributing to the clustering effect that followed.

What Post-Split Performance Actually Shows

The performance record among major split stocks since 2022 is instructive precisely because it is not uniform. Alphabet (NASDAQ: GOOGL) is up 250% since its 20-for-1 split in July 2022. Amazon (NASDAQ: AMZN) is up 124% since its 20-for-1 split in June 2022. Nvidia is up 71% since its 10-for-1 split in June 2024. Tesla (NASDAQ: TSLA) is up 34% since its 3-for-1 split in August 2022. Netflix, which split 10-for-1 in November 2025, is down approximately 20%.

The divergence is analytically useful. The companies that delivered the strongest post-split returns did so because their underlying earnings trajectories continued to compound after the split date. Alphabet's Advertising and cloud businesses kept growing. Nvidia's data centre revenues accelerated through the AI infrastructure build-out. The split contributed nothing to those outcomes.

Netflix's decline illustrates the inverse. The company's announced intention to acquire Warner Bros. Discovery (NASDAQ: WBD) in December 2025 introduced material uncertainty about Capital allocation, Leverage, and strategic direction. That uncertainty compressed the multiple. The split mechanics were irrelevant to the price trajectory; the Acquisition news was the decisive variable. When the deal collapsed in February 2026, the stock partially recovered, but remains below its pre-split level. The lesson is that corporate events, whether positive or negative, carry far greater weight than the nominal price adjustment a split produces.

Morningstar's analysis of the 54 S&P 500 companies that split their stock over the prior decade found no statistically consistent outperformance pattern in the year following a split, reinforcing the case that split announcements are indicators of prior strength, not drivers of future performance.

Candidates Still to Act, and Why Each Case Is Distinct

The four most analytically grounded candidates for future splits each carry a different structural logic.

Meta Platforms (NASDAQ: META) has never executed a forward split since its 2012 IPO. At current price levels approaching $700 per share, it is the most expensive stock among the Magnificent Seven. The case for a split is straightforward on accessibility grounds, but the more relevant argument is index mechanics: as Meta's share price increases relative to the broader market, its absence from the price-weighted Dow Jones Industrial Average becomes increasingly anomalous, creating indirect pressure for management to act.

Microsoft (NASDAQ: MSFT) last split its stock in 2003, a 22-year gap that is the longest in the company's history. All nine of its previous splits occurred at share prices well below $200. At approximately $500 per share, Microsoft is one of only two Dow Jones Industrial Average constituents trading above $500, alongside Goldman Sachs (NYSE: GS). The price-weighted methodology of the Dow creates a specific governance incentive that does not apply to S&P 500 members: a higher nominal share price translates mechanically into a higher index weight, which can distort the index's sector representation in ways that index committees eventually have to address.

Costco (NASDAQ: COST) has not split since 2000 despite its share price trading above $1,000 for an extended period. Its rival Walmart executed a 3-for-1 split in February 2024 when its shares were trading at a fraction of Costco's current price. Management has historically been non-committal on the subject, but the price differential relative to peers is now sufficiently wide that accessibility arguments are difficult to dismiss.

MercadoLibre (NASDAQ: MELI) has never split its stock in its history despite trading above $2,000. The company dominates E-commerce and digital payments across Latin America and has compounded at high double-digit Revenue growth rates for several years. The price level alone makes a case, but management has not signalled intent, and no regulatory filings or corporate communications as of early 2026 suggest the question is under active consideration.

The Structural Takeaway

The 2026 split wave reflects an Equity market in which sustained earnings growth across multiple sectors has driven nominal prices to levels that periodically require structural resets for liquidity and accessibility purposes. It does not signal overvaluation, excessive speculation, or imminent correction. It signals that a number of well-run businesses have compounded in value over an extended period and that their boards have concluded the time has come to reduce the unit cost of ownership.

For investors, the split calendar functions as a useful but limited indicator. It identifies which companies have generated sustained price appreciation, which is a necessary but not sufficient condition for attractive forward returns. The analytical question that actually matters is whether the underlying earnings trajectory, competitive position, and capital allocation discipline justify current valuation multiples. That question is independent of whether a company trades at $80 or $800 per share.
