“That same month, Cursor’s AWS costs — which I believe are the minority of its cloud compute costs — exploded by 104% (or by $6.48 million), and never returned to their previous levels.”
Our reading:
Cursor's AWS costs rose 104% in June 2025 and never fell back to earlier levels through September.

Outcome: Unresolved
We checked, and the evidence so far doesn’t settle it.
Evidence up to . Checked .
Why
The claim is that Cursor's AWS charges rose about 104% ($6.48M) from May to June 2025, and that every month from July to September 2025 stayed above the May level. Checking it needs independent records of Cursor's monthly AWS charges for May to September 2025. The evidence packet has no such records. The sources found either repeat the speaker's own figures or cover Anysphere's funding, valuation and revenue rather than its AWS charges. The searches found no statement from Anysphere or Amazon about the figures. Under the contract, the speaker's own post cannot count as evidence. So the claim can be neither supported nor contradicted.
Caveats
- No independent billing data for Cursor's AWS charges from May to September 2025 was found.
- Revenue, valuation and funding reports do not show AWS charges, so they cannot test the claim.
- The packet records only two search queries, so a relevant disclosure may have been missed.
- Finding no confirmation or dispute from Anysphere or Amazon in these sources does not show that none exists.

How we judged it
- Kind of claim
- Observation
- Deadline
- None given. We don’t add one.
Where we had to interpret
- The baseline for the June increase is May 2025, the month the post lists just before June ($6.19M to $12.67M).
- '104%' allows for rounding: $6.48M on a $6.19M base is about 104.7%, so any June increase of about 100–105%, or about $6.3–6.6M, counts as matching.
- 'Never returned to their previous levels' is read as: every monthly AWS bill from July to September 2025 (the last month of his data) stayed above the May 2025 level.
- The hedged aside that AWS is 'the minority' of Cursor's compute costs ('I believe') is not scored.
Right if: Independent records of Cursor's (Anysphere's) monthly AWS charges show June 2025 about double May 2025 (up roughly $6.5M, about 104%), and every month from July to September 2025 above the May level.
Wrong if: Independent records show the May-to-June 2025 rise was materially different from about 104% / $6.48M, or show that any month from July to September 2025 fell back to or below the May 2025 level.
We wrote this test after the outcome was known.
What would settle it
AWS invoices or billing records, an Anysphere or Amazon disclosure, a filing, or an independent news report that saw Cursor's monthly AWS charges for May to September 2025.
