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.

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.
