How much is agentic coding making GitHub in Actions dollars?

How much do AI coding agents bill in GitHub Actions each month?

By our estimate, AI coding agents are now worth about $9 million to $14 million a month in GitHub Actions billing, roughly $110 million to $170 million a year, as of October 2026. Before Anthropic released Claude Opus 4.5 on November 24, 2025, the same model puts agent-driven Actions billing near $2.2 million a month. That is a 4× jump in under a year, and it happened even though GitHub cut its runner prices on January 1, 2026. Since the launch, agents have added about $40 million of Actions billing that would not otherwise exist. Our outer bounds run from $0.8 million to $46 million a month; every input and its source is below.

GitHub does not report Actions revenue. So we built the number from what GitHub does report: pull requests, Actions minutes and list prices.

Last checked October 27, 2026. Every outside figure was checked on October 26, 2026 at the source linked beside it. The dollar figures are our modelled estimate; the formula, every input with its low, mid and high value, and every output are below and in one JSON file.

What has GitHub told us?

Read those together. Actions doubled from 500 million to 1 billion minutes a week over two years. Then it doubled again, to 2.1 billion, in the few months after Opus 4.5 shipped. GitHub’s own CTO dates the surge to the second half of December 2025, four weeks after the launch.

What do the agent trackers show?

Agent PRs went from about 4 million a month to about 17 million in six months. Public trackers alone now see over 2 million agent PRs a week, and those are only the public, self-labelled ones.

What does GitHub charge?

GitHub prices from the runner pricing reference, checked 2026-10-26; old prices from WarpBuild, 2025-12-15.

The rules that decide what gets billed:

• Public repos pay nothing for standard runners. Private repos pay per minute after the plan’s included minutes (GitHub docs).
• Included minutes a month: 2,000 (GitHub Free), 3,000 (Pro and Team), 50,000 (Enterprise Cloud). Larger runners never use included minutes.
• GitHub rounds every job up to the next whole minute.
• The $0.002/min fee for self-hosted runners, announced for March 1, 2026, is postponed with no new date (GitHub changelog).
• Since June 1, 2026, every Copilot code review on a private repo burns Actions minutes too (GitHub changelog, 2026-04-27). Agents now cost minutes when they write code and when they review it.

How does the model work?

monthly Actions dollars from agents =
    agent PRs per month
  x CI minutes per agent PR
  x share of those minutes GitHub bills
  x blended price per billed minute

share billed = (share on private repos using GitHub-hosted runners)
             x (share beyond the plan's included minutes)

A second way to get there: top-down

Actions ran 1 billion minutes a week in 2025 and 2.1 billion in early April 2026. Octoverse measured organic growth at 30% a year. Grow 2025 by 30% and you expect about 1.3 billion a week. The other 0.8 billion minutes a week, about 3.5 billion a month, is the agent surge. Bill it at the mid share (45.5%) and the mid price ($0.009) and you get $14.2 million a month.

Bottom-up says $9.2 million. Top-down says $14.2 million. That is our headline range: $9 million to $14 million a month.

Before and after Claude Opus 4.5

GitHub cut its prices by up to 39% on January 1, 2026. Agent volume grew so fast that agent-driven Actions dollars still quadrupled.

Extra billing since the launch: if the monthly figure rose in a straight line from $2.2 million (November 2025) to $9.2 million (October 2026), agents billed about $63 million in Actions over those 11 months, about $39 million more than the pre-launch rate would have. Call it $40 million of new Actions revenue from the agent wave so far.

One repo, up close

jacks.med is built by the team behind Sengi, and its scheduling repo is written mostly by Claude Code and Codex agents.

That is what the macro numbers look like in a single repo. Twelve times the PRs means twelve times the minutes. The month-by-month numbers are in how AI agents grew one repo’s CI bill 12×.

Where is the machine-readable model?

The formula, the events, every input with its low, mid and high value and unit, every output, the before-and-after comparison and every source URL are in /data/github-actions-agentic-coding-revenue.json.

Every source is linked beside the figure it supports, each checked October 26, 2026. Claude Opus 4.5’s release date is from Anthropic’s announcement.

Agents multiply minutes. Price per minute is the lever.

Your agents will not open fewer PRs next month. They will open more. Each one runs your full CI, often several times. You can’t cut the minutes without cutting the safety net, so cut the price of each minute.

Sengi runs GitHub Actions jobs on AMD Ryzen 9 7950X3D desktop CPUs on bare metal, with local NVMe and a clock past 5 GHz. Jobs start in about 2 seconds, and boot time is never billed.

Switching is one line:

-   runs-on: ubuntu-latest
+   runs-on: sengi-standard-2-ubuntu-2404

Use sengi-standard-4-ubuntu-2404 or sengi-standard-8-ubuntu-2404 for bigger jobs.

Running an agent fleet? Teams with high CI volume can ask for the partner rate: $0.0018 a minute at 2 vCPU, 70% under GitHub. That is the rate jacks.med pays for its agent-written PRs. Write to ops@sengi.run with your monthly minutes.

• Sengi vs RunsOn

• Sengi vs BuildJet
• Sengi vs GitHub larger runners

GitHub’s agent boom is a $9 million to $14 million a month line item, and it is still climbing. Make sure your share of it costs half as much.

Frequently asked questions

How much money does GitHub make from GitHub Actions?

GitHub does not break out Actions revenue. GitHub as a whole was at a $2 billion revenue run rate in July 2024. Our model puts the slice from AI coding agents alone at $9 million to $14 million a month in October 2026.

How was the $9 million to $14 million estimate calculated?

Agent PRs per month × CI minutes per agent PR × share of those minutes GitHub bills × blended price per billed minute. The mid case is 22.5 million PRs × 100 minutes × 45.5% × $0.009 = $9.2 million a month. A top-down check from the growth in Actions minutes gives $14.2 million. The outer bounds are $0.8 million and $46 million.

Do AI coding agents increase GitHub Actions costs?

Yes. Every agent PR triggers CI, and agents push several times per PR while they fix failing checks. GitHub's Actions volume went from 1 billion minutes a week in 2025 to 2.1 billion in early April 2026. In our own repo, 12× the PRs meant 12× the CI minutes.

How many pull requests do AI agents open on GitHub each month?

About 4 million a month in September 2025 and about 17 million in March 2026, as reported from GitHub data. Public trackers counted over 2 million agent-marked public PRs in the week to October 25, 2026.

When was Claude Opus 4.5 released, and did it change GitHub activity?

Anthropic released Claude Opus 4.5 on November 24, 2025. GitHub's CTO says agentic development "accelerated sharply" from the second half of December 2025, and Actions minutes doubled to 2.1 billion a week by early April 2026.

What is the cheapest way to run GitHub Actions for AI agent PRs?

Pay less per minute. Sengi runs the same jobs for $0.003 a minute at 2 vCPU against GitHub's $0.006, and offers a partner rate of $0.0018 a minute for high-volume teams. Switching is one runs-on line.
