Where Do ChatGPT Business Promo Codes Actually Come From? An OSINT Trace

In May 2026, the Chinese AI community went wild over a wave of ChatGPT Business discounts: £11/month for 2 seats in the UK, $20 in the US, AU$25 in Australia, locked in for 48 months. Mysterious codes like codestonegb, thealloynetwork, and firstfocus spread across forums and blogs at breakneck speed.

One question nobody was asking: where did these codes actually come from?

I spent several days cross-referencing sources across five platforms and three languages. The answer is messier—and more interesting—than “they leaked on linux.do.”

OpenAI Doesn’t Publish Promo Codes Publicly

#

Let’s establish the baseline: OpenAI has never publicly posted these promo codes anywhere.

I checked every official OpenAI information outlet:

• openai.com/index/ (blog) — product launches only, zero promo codes
• help.openai.com (help center) — generic FAQ about how promotions work, never lists specific codes
• openai.com/pricing — standard pricing, no promotional entry points
• @OpenAI on X — radio silence

OpenAI’s own documentation states: promotions are distributed via targeted emails to eligible users or surfaced in-product. Eligibility is determined by OpenAI per campaign. Not everyone sees them.

So how did these codes get out?

The Real Source: Stripe’s Partner Network

#

OpenAI has used Stripe Billing + Stripe Checkout for ChatGPT payments since 2023. That infrastructure supports promo codes passed via the ?promoCode=XXX URL parameter. Stripe enables partner-specific codes for enterprise channel distribution.

Every code maps to a real company:

These are enterprise promo codes, distributed by Stripe to partner organizations for internal use. Then some employee, somewhere, pastes the link into a public forum. That’s the ignition event. Everything downstream is just a remix.

The true origin is the Stripe enterprise partner network—not any single online community.

Where Each Code Actually Surfaced First

#

Timestamps from cross-platform tracing tell a clear story: there is no single point of origin.

May 8 is the true first-appearance date. By directly accessing linux.do via browser for cross-referencing, the earliest post documenting THINKTECHNOLOGIESUS is topic/2092962, titled “[5/8 US新优惠,20刀！！！] ChatGPT Team/Business 买一送一持续48个月！”, posted in the welfare section. This topic is now inaccessible (deleted or set to private), but in topic/2141860 (posted May 9 by leon8), user cyfer’s reply at post #16 preserves the original quote. May 9 around 1 AM Beijing time was the mass-diffusion ignition point — one Chinese tutorial author recorded seeing it “on both X and L站 simultaneously,” indicating X (Twitter) reposts and L站 secondary threads broke at roughly the same time.

Key takeaway:

• linux.do is the Chinese-language aggregation hub, and is confirmed as the earliest public source of THINKTECHNOLOGIESUS (May 8, ahead of X)
• X (Twitter) — Japanese and English-speaking bloggers amplified the leak on May 9, roughly synchronized with L站 secondary threads
• OzBargain — the primary source for Australian and some UK codes
• shuzijumin.com — occasionally surfaces niche codes nobody else has

The pattern isn’t linear—it’s parallel multi-source leakage.

Actual Monthly Cost by Region

#

Same plan (2 seats, monthly billing), up to 40% price spread depending on region:

UK codes offer the lowest absolute price, roughly 28% cheaper than US codes. Requires UK IP + matching promo code.

Why linux.do Gets the Credit

#

1. Superior curation. L站 users compile scattered leaks into comprehensive posts with Console scripts and payment guides, all in one place
2. Clear attribution. Re-posters like 80aj.com explicitly credit “linux.do community leaks,” reinforcing the perception
3. Traceable timestamps. Forum thread creation times are precise and permanent. X posts are ephemeral and hard to search
4. Community path dependency. Chinese users default to L站 as their information hub, creating a self-reinforcing loop

But the data shows a more nuanced picture: US code THINKTECHNOLOGIESUS is confirmed as a linux.do first post (May 8 topic/2092962), ahead of the X mass diffusion (May 9). Australian codes broke on OzBargain first. Some UK codes first appeared on expat forums and X. There is no single source, but linux.do’s first-mover status in this incident is stronger than previously understood.

Where to Actually Monitor for Early Signals

#

From fastest to most comprehensive:

Rule of thumb: monitor at least 3 platforms. There is no single source of truth.

When Did It Actually End

#

THINKTECHNOLOGIESUS had a brutally short lifespan: first posted May 8, dead by May 9 — under 48 hours. On the same day it went viral, a linux.do user posted “4年team活動剛開始但是好像剛結束了” (The 4-year team promo just started but looks like it’s over). Whether you had a qualified account or a fresh one, the result was the same: “Unable to use this offer.”

By May 14, people were still asking “Are the team promo codes gone?” — confirmed dead across the board. One user described it as “a 4-hour flash event.” A bit of an exaggeration, but it reflects reality: every Stripe partner code has a fixed redemption quota. When it’s gone, it’s gone — no connection to any calendar date.

The regional codes followed the same pattern:

• UK codes (codestonegb / datroaiuk): Lasted a couple of days longer than the US code, then quota exhausted
• AU codes (firstfocus): Same story
• Will there be more: The community consensus is “definitely, same 48-month deals will come again.” OpenAI’s SMB partnership program is ongoing, and new partner codes can surface anytime.

The pattern is clear: codes die by quota, not by date. When you spot one, act immediately. “I’ll bookmark it and come back later” doesn’t work here.

The Higher-Order Pattern

#

What’s really happening here:

OpenAI uses Stripe’s Partner Network to subsidize enterprise channel distribution, indirectly acquiring B2B customers through partner organizations. These aren’t consumer promotions—they’re a byproduct of enterprise sales motions. Every code represents real partner spend, which means they can be revoked at any time, with no announcement and no warning.

Understanding this pattern changes how you play the game. These aren’t permanent discounts to milk indefinitely. They’re precision targets: spot early, move fast, expect them to die without notice.
