OpenAI turns away new $200-a-month ChatGPT subscribers to protect Astra capacity
OpenAI paused new sign-ups to its $200 ChatGPT Pro plan because Astra demand outran its compute. It closed the tier to new buyers and left the price where it was, and existing Pro accounts keep running.

What happened
- OpenAI said on Thursday it was pausing new sign-ups and upgrades to the $200-a-month ChatGPT Pro plan, the tier where its new Astra model is available, for lack of compute capacity.
- A day earlier, product head Thibault Sottiaux had called demand for Astra "unprecedented" and warned the company might have to pause new Pro subscriptions for a bit if it kept up.
- Astra's marquee feature, computer use, fills out forms and navigates web pages on a desktop at what OpenAI president Greg Brockman called "superhuman speed".
- OpenAI temporarily halted sign-ups to the $20-a-month ChatGPT Plus plan in November 2023, after its first developer conference drove a surge in usage.

Why it matters
- decision The $200 price stays and the door closes, so revenue growth at the top of OpenAI's consumer price list now waits on hardware deliveries.
- constraint Scarce Astra capacity is committed to existing Pro accounts and the cheaper tiers below them, and buyers willing to pay $200 today are put in a queue.
- exposure If the Astra surge cools before the 2026 machines are installed, OpenAI owns hardware that depreciates in a few years against demand it no longer has.
- precedent This is the second capacity pause since November 2023 and it lands at ten times that price point, so paying customers can expect the top tier to be rationed at each flagship launch.
The Pro tier carries 20 times the usage allowance of the Plus plan below it [2], and Plus cost $20 a month when OpenAI last ran out of room, in November 2023 [12]. Ten times the price for twenty times the usage puts each unit of allowance at half the cost at the top of the price list that it costs one tier down [3]. So the accounts straining the fleet hardest are the ones paying least per unit of it [3][3]. Thibault Sottiaux, OpenAI's head of product, wrote on X that the $200 plan puts the most strain on the company's systems [3].
A company with more demand than it can serve can move the price or move the quantity. OpenAI moved the quantity. "We wanted to take the smallest step that allows us to continue giving the broadest access possible," Sottiaux said, adding that OpenAI is "working on adding more capacity" and that existing Pro accounts are unaffected [4][5]. The day before, he wrote on X: "We're pulling all the levers possible to sustain the demand, but I've not seen anything like it until now and we went through very steep growth before" [7]. OpenAI did not respond to Fortune's request for comment [18].
Astra went first to a handful of enterprise customers, to buy OpenAI time to scale its compute [8]. That time was bought against a fleet OpenAI says grew from 0.2 gigawatts in 2023 to about 1.9 GW in 2025 [14]. The capacity lined up from the second half of 2026 comes to 26 GW once you add at least 10 GW of Nvidia systems, the 6-GW AMD agreement and 10 GW of Broadcom-built custom accelerators [16][1], roughly 13.7 times the 2025 number [2]. Stargate, the buildout behind part of it, is budgeted at $500 billion over four years [15].
Two readings fit the record. In the first, the ceiling is physical: computer-use demand is genuine, OpenAI is short of machines until the 2026 deliveries arrive, and the queue clears itself. In the second, the flat fee is the problem, since OpenAI said Astra burns through usage allowances faster than GPT 5.6 Sol [11], and a subscription that meters nothing against consumption that scales with how long an agent runs gets fixed with a price, not a gigawatt. The 2023 halt was temporary [12]. If Pro reopens at $200 with the same allowance, capacity was the binding constraint; if it reopens dearer, or metered, the pause was about gross margin.
What to watch
- Whether Pro reopens at $200 with the same allowance, at a higher price, or with metered usage.
- Whether the rationing spreads down to the cheaper ChatGPT tiers as Astra usage grows.
- Whether OpenAI publishes a 2026 compute figure to set against the 1.9 GW it reported for 2025.
