SpaceX Issues 389 Million Shares as Cursor Deal Closes

SpaceX completed its $60 billion all-stock acquisition of Cursor on August 14, converting Anysphere equity into 389,289,254 Class A shares and folding the AI coding platform into SpaceXAI as a wholly owned subsidiary. SPCX shares slipped in Friday trading near $137 to $140 after an earlier five-day climb.

The close locks developer distribution for Grok just as the market digests the share issuance that a lower seven-day average price produced.

How the Share Conversion Worked

An August 14 Form 8-K completion filing shows X67 Inc., the SpaceX merger subsidiary, merged into Anysphere. Cursor survived as the wholly owned unit. The implied equity value stayed fixed at $60.0 billion. The exchange ratio used SpaceX’s volume-weighted average closing price over the seven trading days immediately before closing.

That formula produced a concrete share count instead of a floating cash bill. Common and preferred shares outstanding right before the effective time converted into rights to receive the 389,289,254 Class A shares. Vested restricted stock units converted into rights to 1,752,426 Class A shares before tax withholding. Cash covers fractional shares.

Unvested awards stay subject to their original service and vesting schedules. The issuance relied on the Section 4(a)(2) exemption for a non-public offering. SpaceX first signed the merger agreement on June 16 and expected a third-quarter close. It delivered on schedule.

• Fixed $60 billion equity value sets the numerator.
• Seven-day VWAP sets the denominator and therefore the share count.
• Lower average price means more SPCX shares change hands for the same label.
• Former Cursor holders and employees now ride the public stock’s performance.

The math is simple and mechanical. It is also the second-order effect that matters more than the headline number.

SPCX Digests the Dilution After a Five-Day Climb

Shares opened Friday near $143 and traded as low as $135.53 before recovering toward $140, according to market data cited across reports. That left the stock roughly 2 percent lower on the session in some feeds and still well below the June peaks that followed the original deal announcement and IPO afterglow.

Stats snapshot

• ~$137-140: Friday trading range after the close announcement
• $135.53: intraday low cited in contemporaneous coverage
• +23%: roughly the five-day climb into the close amid Grok 4.6 and deal anticipation
• $300 / $600: Morgan Stanley base and bull cases retained by Adam Jonas

Crowd tallies on X quickly noted the arithmetic. Because the share count floats with the recent average, a softer SPCX price handed Cursor holders more paper than a higher-price close would have. One widely shared observation put the seven-session average near levels that required hundreds of millions of shares, far above the count that would have applied at June announcement prices near $200. The $60 billion label stayed constant. Ownership transfer did not.

Existing holders absorb the new float. Former Cursor investors and employees gain direct exposure to Starlink, Starship, and the AI stack. That transfer is permanent.

Cursor’s Path From $29 Billion Private Round to $60 Billion Exit

Anysphere, the company behind Cursor, raised its Series D of Series D $2.3 billion at $29.3 billion in November 2025. Investors included Accel, Thrive, Andreessen Horowitz, Coatue, NVIDIA, and Google. At that point the company reported crossing $1 billion in annualized revenue, a team past 300 people, and in-house models already generating large volumes of code.

1. 2022-2023: Founded by MIT alumni; Cursor editor launches.
2. August 2024: Series A at roughly $400 million valuation.
3. June 2025: Series C $900 million at $9.9 billion.
4. November 2025: Series D $2.3 billion at $29.3 billion; $1B+ ARR disclosed.
5. April 2026: SpaceX compute and option arrangement (buy for $60B or $10B collaboration fee).
6. June 16, 2026: Binding merger agreement signed.
7. August 14, 2026: Merger effective; Cursor wholly owned by SpaceX.

The jump from the last private round to the $60 billion implied equity value compressed enormous growth into under a year. An earlier $2.3 billion Cursor funding round already marked the company as a category leader in AI-assisted coding. SpaceX simply paid the next multiple in stock.

Grok 4.6 Arrived Days Before the Legal Close

SpaceXAI released Grok 4.6 on August 12 with a focus on long-running agents, ambitious interactive work, and coding. The model is available immediately inside Cursor and Grok Build, with doubled included usage for the first week. Pricing starts at $2 per million input tokens and $6 per million output tokens.

Grok 4.6 release notes and benchmarks show competitive scores on agentic coding suites including CursorBench and FrontierCode. The product already treated Cursor as a primary distribution channel before the legal merger finished.

Today, we have officially closed our acquisition. We will join the SpaceXAI team to help make Grok the world’s most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more.

That line comes from Cursor’s own closing announcement post on August 14, which drew millions of views. The company kept the Cursor brand and told users the work continues under the SpaceX roof.

Joint work predated the June agreement. An earlier compute arrangement already gave Cursor access to SpaceX GPU capacity. The merger simply removes the optionality and makes the teams one legal entity.

Who Gains the Coding Surface and Who Absorbs the Float

Cursor’s enterprise footprint (tens of thousands of customers, heavy Fortune 500 penetration in earlier disclosures) now sits inside a company that also runs Starlink, launches, and large-scale AI training. Developers who already live in the editor gain tighter Grok defaults and agent tooling. SpaceXAI gains a high-signal data flywheel from real professional codebases and a distribution channel that pure model companies still fight for.

Existing SPCX holders pay in ownership percentage. The 389 million new shares plus the converted awards expand the Class A float at a moment when the stock had already retraced from its post-IPO and deal-announcement highs. That is the clear near-term cost.

Rival coding tools and model labs lose a well-capitalized independent player. Cursor no longer needs to raise another private round or chase its own IPO. It can draw on Colossus-scale compute and the broader SpaceX balance sheet. Public-market paths for other AI labs, including the OpenAI and Anthropic public-market paths, now look different against a vertically integrated competitor that owns both rockets and the editor millions of engineers open every day.

• Cursor employees and early investors: large SPCX stakes at the VWAP-determined ratio.
• Enterprise Cursor users: continued product plus deeper Grok integration.
• SpaceXAI: coding distribution and feedback loops for agent models.
• SPCX public holders: permanent dilution in exchange for the AI software revenue stream.

Morgan Stanley’s Adam Jonas has kept a $300 base target and a $600 bull case, with Cursor’s potential path from roughly $8 billion ARR by year-end 2026 toward $33 billion by 2030 cited as one bridge to the upside scenario. Those remain forecasts, not SpaceX guidance.

The Platform Bet Now Runs Without an Exit Ramp

The April option structure had given SpaceX a clean out: buy at $60 billion or pay $10 billion for collaboration rights. Pulling the trigger removes that flexibility. Cursor is inside the house. Grok Build, Grok Bot, the API, and the editor itself are now one product surface under SpaceXAI.

Short-term price action on Friday reflected the share math more than any sudden doubt about the product. The five-day run-up into the close had already priced much of the anticipation. The legal close simply made the ownership transfer real and permanent.

For SpaceX the deal converts recent public-market currency into a strategic asset that pure model competitors still lack: an editor with daily professional usage and a direct path to improve coding and agent performance. Whether the ARR trajectory justifies the dilution will show up in subsequent quarters. The share count is already locked.

Frequently Asked Questions

How many SpaceX shares did Cursor shareholders receive?

Common and preferred shares converted into rights to an aggregate of 389,289,254 Class A shares. Separately, vested RSUs converted into rights to 1,752,426 Class A shares before tax withholding, with cash paid for fractional shares.

What happens to unvested Cursor equity awards?

Unvested RSUs converted into approximately 29,128,326 SpaceX RSUs and outstanding options into approximately 44,365,047 options to purchase SPCX Class A stock. Those awards remain subject to their original vesting and service conditions.

What was Cursor’s last private valuation before the SpaceX deal?

The November 2025 Series D raised $2.3 billion at a $29.3 billion post-money valuation. The SpaceX merger later used a $60 billion implied equity value for the exchange ratio.

Why did the number of shares depend on a seven-day average?

The merger agreement fixed Cursor’s equity value at $60 billion and set the exchange price as the volume-weighted average closing price of SPCX Class A stock over the seven consecutive trading days immediately before closing. A lower average produces a higher share count for the same dollar value.

Which SpaceXAI products will Cursor work on?

Cursor’s closing statement said the team will join SpaceXAI to improve Grok, Grok Build, Grok Bot, the Grok API, Cursor itself, and related tools. Grok 4.6 was already live inside Cursor two days before the legal close.
