BlackRock stock split: what it means for traders

Stock splits can draw attention when reviewing the long-term history of large, publicly traded companies.

They can reshape how a share is presented to the market without changing the underlying value of the business, making them a useful reference point when looking at a company’s past corporate actions.

BlackRock (BLK) is one of the world’s largest asset managers, and its share price often draws attention from investors and market observers. Stock splits are a common consideration for large-cap companies, as they can change how accessible a share appears without altering a firm’s underlying market value.

What is a stock split?

A stock split is a corporate action in which a company increases the number of its outstanding shares by issuing additional shares to existing shareholders at a set ratio. This lowers the price per share while leaving the total value of a shareholder’s position unchanged.

For example, in a 2-for-1 split, shareholders receive one additional share for every share they already hold. Their share count doubles, the share price halves, and the company’s market capitalisation stays the same because the business’s value is unaffected.

Companies may use stock splits to improve the perceived affordability of their shares and broaden potential market participation. Lower entry prices can also support trading volumes.

BlackRock’s latest stock split

Publicly available historical data shows that BlackRock has completed one stock split to date. This took place on 5 June 2007 and remains the most recent split recorded across major financial and corporate reporting sources.

The event is commonly listed with a cumulative split effect of 1:1, reflecting that there is no lasting change to the split-adjusted share count. No subsequent stock split has been reported up to mid-December 2025, and no recent filings or disclosures indicate a newer action.

Why did BlackRock conduct a share split?

Companies may choose stock splits to make shares appear more accessible by reducing the share price without affecting the firm’s valuation. This can help widen the potential investor base and support liquidity, particularly when a company’s share price has increased over time.

BlackRock did not provide extensive long-term commentary on its 2007 split, though the rationale appears consistent with general market practice at the time: improving affordability and supporting smoother trading conditions.

Since then, no similar corporate action has been announced, and more recent company communications do not highlight any new considerations relating to share splits.

Will BlackRock split again in 2026?

As of 16 December 2025, BlackRock has not announced or signalled any intention to conduct a stock split in 2026. Public statements, regulatory filings and investor-relations materials show no reference to an upcoming split.

Any future split would require board approval and formal disclosure. No such items currently appear in the company’s published corporate activity.

Speculation can arise around companies with high share prices, but there is no available evidence that BlackRock plans a split in the near term. The firm’s recent communications continue to focus on operational performance, assets under management and longer-term themes.

BlackRock stock split history

Across leading financial data providers, BlackRock’s split history is consistent: one event, dated 5 June 2007. While some services display the split using different formatting conventions, the underlying data does not vary.

Because stock splits do not change a firm’s market value, the absence of additional splits in nearly two decades reflects a preference for a stable share structure rather than a need for ongoing adjustments.

Latest earnings: BlackRock FY2025 results

BlackRock’s most recently reported figures show continued revenue growth, stable earnings and strong asset-gathering activity.

For Q3 2025, the company reported:

Diluted earnings per share (EPS): $8.43
Adjusted EPS: $11.55
Quarterly revenue: approximately $6.5bn, with year-on-year growth of about 25%
Assets under management (AUM): approximately $13.4–$13.5tn
Total net inflows: around $205bn for the quarter

These figures reflect broad-based activity across the business. Rising AUM and consistent inflows indicate continued demand across the firm’s product range, which includes ETFs, fixed-income strategies, multi-asset solutions and private markets.

Operational performance remains central to BlackRock’s messaging, with recent updates emphasising the scale of its platform and its investment in long-term strategic areas.

Outlook and upcoming developments

BlackRock’s 2025 communications highlight several long-term themes – described by the company as 'mega forces'. These include:

Infrastructure investment.
Private markets.
Retirement solutions.
Digital assets.
Growth across global ETFs and ETPs.

The firm has also noted continued inflows into its exchange-traded products and a growing range of fixed-income, liquid alternatives and thematic strategies.

None of the latest company updates refer to a potential stock split, and there is no indication that such an action is under consideration for 2026. Instead, the focus remains on long-term growth drivers, product innovation and global distribution capabilities.

As with any large financial institution, decisions about capital structure or share issuance would depend on board-level assessments and market conditions.

FAQ

When did BlackRock stock split?

Publicly available split-history databases record one stock split for BlackRock. The event took place on 5 June 2007 and remains the only split listed across major financial data sources. No additional split dates appear for BLK, and providers either reference the 2007 adjustment or note that the company has no further split history.

When did the BlackRock stock split take effect?

The split became effective on 5 June 2007, the date shown in corporate filings and market split-tracking tools. On that day, BLK closed at around $152.20, compared with approximately $152.93 on the previous trading day. This reflects normal price movement rather than a mechanical reset, as the action was recorded as a 1:1 adjustment.

Did BlackRock have a stock split before?

How much was BlackRock stock after the split?

On 5 June 2007, BlackRock’s closing share price was about $152.20, compared with roughly $152.93 the preceding day. Because the recorded action was a 1:1 adjustment, the share price did not undergo a typical multi-for-one split change.

Why did BlackRock split its stock?

BlackRock has not published detailed commentary explaining the rationale behind the 2007 adjustment. A 1:1 split is usually administrative and does not alter a shareholder’s economic exposure.
