SpaceX closes its $60 billion Cursor buy; OpenAI cuts off the coding tool's access to its models

August 30th, 2026: OpenAI to cut off Cursor's access to its models

Overview

Updated Aug 31

SpaceX went public on June 12 in the largest stock-market debut ever. Five days later, it agreed to spend $60 billion on Cursor, an AI coding tool barely three years old. The all-stock deal closed on Aug. 14.

SpaceX wanted Cursor's developer data and talent to fix a weak spot: Elon Musk's xAI has trailed rivals in frontier AI. OpenAI, which supplies models to Cursor, now says it will cut off access by Nov. 12, citing a lack of trust in Musk's companies.

Why it matters

SpaceX is converting fresh public-market value into AI software, betting developer data can close Grok's gap with OpenAI and Anthropic.

  1. OpenAI to cut off Cursor's access to its models

    Latest Conflict

    OpenAI says it will end developers' access to its models on Cursor by Nov. 12, citing an inability to trust SpaceX to follow its terms of service. OpenAI models serve about 5% of Cursor user traffic.

  2. Cursor launches Origin code hosting

    Product

    Three days after the deal closed, Cursor began rolling out Origin, a code-hosting service, in early beta on all paid plans.

  3. SpaceX closes Cursor acquisition

    Deal

    SpaceX completes its all-stock acquisition of Anysphere at an implied value of $60 billion, issuing about 389.3 million Class A shares. Cursor becomes a wholly owned subsidiary within SpaceXAI.

  4. SpaceX agrees to buy Cursor for $60 billion

    Deal

    SpaceX exercises its option in an all-stock deal, its first major move as a public company. Close is expected in Q3, pending regulatory approval.

  5. Shares jump 19% on debut

    Market

    SpaceX stock closes its first Nasdaq session up 19%, valuing the company near $1.77 trillion.

  6. SpaceX prices record IPO

    Market

    SpaceX prices 555.5 million shares at $135 each, raising $75 billion, the largest IPO on record.

  7. SpaceX secures an option to buy Cursor

    Deal

    SpaceX takes an option to either partner with Cursor or acquire it for $60 billion later in the year.

  8. Series D values Cursor near $29 billion

    Funding

    A $2.3 billion round co-led by Accel and Coatue roughly tripled the company's valuation.

  9. Four MIT students start Anysphere

    Origin

    Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger found the company behind Cursor.

Scenarios

1

SpaceX closes the Cursor deal by end of Q3

Likely Resolves by Q3 2026

Discussed by: Yahoo Finance, CNBC, company filings

Regulators clear the all-stock purchase without major conditions, and the deal finalizes on the timeline SpaceX set. Cursor becomes part of SpaceX, and its developer data starts feeding xAI's work. This is the path both companies have stated they expect.

2

Antitrust review pushes the deal past 2026

Possible Resolves by End of 2026

Discussed by: Antitrust commentators citing FTC and DOJ merger practice

A regulator opens an extended review of how a Musk-controlled buyer absorbing a widely used coding tool affects competition and data flows to Grok. A second request or court challenge delays closing well beyond the third quarter.

3

The acquisition is called off before closing

Unlikely Resolves by End of 2026

Discussed by: Deal-risk analysts noting all-stock value swings

Because the price is paid in SpaceX shares, a sharp drop in the stock or a regulatory block could push either side to walk away. A termination would leave Cursor independent and reset Musk's AI plans.

4

Cursor still sells under its own name a year later

Uncertain Resolves by Q2 2027

Discussed by: Software analysts comparing it to GitHub under Microsoft

SpaceX keeps Cursor running as a standalone product and brand, the way Microsoft kept GitHub, rather than folding it into xAI. Developers keep buying Cursor subscriptions under the Cursor name through mid-2027.

5

OpenAI's model cutoff stands, pushing Cursor deeper into SpaceX's own models

Likely Resolves by Nov 12, 2026

Discussed by: OpenAI, Cursor CEO Michael Truell, TechCrunch, LA Times Now

If OpenAI follows through on its Nov. 12 cutoff, Cursor loses about 5% of user traffic and pivots more of its inference to Grok. Cursor said it is talking with OpenAI to resolve the issue; the two sides' history makes a resolution uncertain.

6

SpaceXAI's Grok gains ground in AI coding

Possible Resolves by Q2 2027

Discussed by: The Agentic Review, business-news-today.com

With Cursor folded into SpaceXAI and access to the largest GPU fleet in the world, SpaceX targets Anthropic's lead in AI coding. Grok 4.6, released Aug. 12 and trained jointly with SpaceXAI, is an early product of the combined team.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

February 2014

Facebook buys WhatsApp (2014)

Facebook agreed to pay about $19 billion, mostly in stock, for the messaging app WhatsApp, then a young company with a small team. The price stunned the industry.

Then

The deal closed after European regulators reviewed it and cleared it with conditions.

Now

Facebook was later fined for misstatements it made to EU regulators about merging the two services' data.

Why this matters now

It shows how a giant stock-funded purchase of a fast-growing startup draws regulatory focus on data, a live question given Cursor's data feeding Grok.

August 2016

Tesla buys SolarCity (2016)

Tesla agreed to buy SolarCity, a solar firm where Musk was the largest shareholder and chairman, in a $2.6 billion all-stock deal. Critics called it a bailout of a related company.

Then

Tesla shareholders approved the deal, but investors sued, alleging Musk steered it.

Now

A Delaware judge ruled in 2022 that the deal was fair to shareholders, ending the main case.

Why this matters now

Musk controls both SpaceX and the xAI unit set to gain from Cursor, raising the same related-party questions that shadowed the SolarCity purchase.

June 2018

Microsoft buys GitHub (2018)

Microsoft agreed to buy GitHub, the code-hosting platform developers depended on, for $7.5 billion in stock. Many developers feared Microsoft would degrade or wall off a neutral tool.

Then

Microsoft kept GitHub independent with its own brand and chief executive.

Now

GitHub grew sharply and later became the base for the Copilot AI coding tool.

Why this matters now

It is the closest model for a tech giant buying a developer tool with stock and the question of whether the new owner keeps it open or folds it in.
