As of September 26, 2026, OpenRouter has not filed a Form S-1 or F-1 with the US Securities and Exchange Commission on EDGAR, which covers only US filings, and there is no public filing to track toward an IPO. Instead, Axios reported on July 24, 2026, citing the Wall Street Journal, that Stripe was in talks to acquire OpenRouter for around $10 billion, up from a $1.3 billion valuation set earlier in 2026. On August 16, 2026, Bloomberg reported that Stripe had finalized an agreement to acquire OpenRouter for more than $7 billion, below the roughly $10 billion figure described in the July talks. TechCrunch confirmed the same deal that day, citing Bloomberg's more-than-$7-billion figure, and noted OpenRouter had raised a $113 million Series B round in May 2026 at a reported $1.3 billion valuation, with investors including Sequoia, a16z, Menlo Ventures, and CapitalG. A completed acquisition by Stripe would end any path to an independent OpenRouter IPO rather than advance one. Track SEC EDGAR and any direct statement from OpenRouter or Stripe, not secondary reporting.
Axios reported on July 24, 2026, citing the Wall Street Journal, that Stripe was in talks to acquire OpenRouter for around $10 billion, up from a $1.3 billion valuation set earlier in 2026. That was reporting on a negotiation in progress, not a signed agreement or a stock listing.
Three weeks later, on August 16, 2026, Bloomberg reported that Stripe had finalized an agreement to acquire OpenRouter for more than $7 billion. TechCrunch confirmed the same deal that day, citing Bloomberg's more-than-$7-billion figure. Neither report is a filing, and neither is a statement from OpenRouter or Stripe as reviewed here.
The valuation moved twice in three months
TechCrunch reported on August 16, 2026 that OpenRouter had raised a $113 million Series B round in May 2026 at a reported $1.3 billion valuation, with investors including Sequoia, a16z, Menlo Ventures, and CapitalG.
By late July, Axios reported acquisition talks valuing OpenRouter at around $10 billion, roughly 7.7 times that Series B figure. By mid-August, Bloomberg's reported agreement priced the deal at more than $7 billion instead, a lower number than the July talks but still well above the May valuation.
What would actually confirm a listing
SEC EDGAR covers only US filings, and no Form S-1 or F-1 for OpenRouter appears there as of September 26, 2026. A Form S-1 is the standard US registration statement for a domestic issuer's IPO; a Form F-1 is the equivalent for certain foreign private issuers. Neither has been filed.
If the Stripe acquisition reported by Bloomberg and TechCrunch closes, it would end OpenRouter's path to an independent IPO rather than move it forward. Until OpenRouter or Stripe makes a direct statement, or a filing appears on EDGAR, the acquisition reporting is the only verified status.

Searches like 'When Will OpenRouter IPO? Stripe Is Reportedly Buying It Instead' are research questions: what a filing or a company statement confirms, what has only been reported, and what is still unknown.
What counts as a listing step
For an IPO, the primary record is a registration statement filed with the securities regulator of the listing market, such as an S-1 or F-1 on SEC EDGAR for a US listing. Funding rounds, valuations and secondary-market prices are context, not listing steps.
Segmara role
Segmara takes reviewed pre-IPO allocation requests funded by Stripe USD credits from $25 ($1.00 starter credit); no allocation is guaranteed. It also publishes dated indicative reference marks across 140+ private companies. Nothing on this page is investment advice.

Axios reported on July 24, 2026, citing the Wall Street Journal, that Stripe was in talks to acquire OpenRouter for around $10 billion, up from a $1.3 billion valuation set earlier in 2026, a reported negotiation, not a signed deal or an IPO filing.
Bloomberg reported on August 16, 2026 that Stripe had finalized an agreement to acquire OpenRouter for more than $7 billion, below the roughly $10 billion figure described in the July talks reported by Axios three weeks earlier.
TechCrunch confirmed the same Stripe-OpenRouter deal on August 16, 2026 (more than $7 billion, per Bloomberg), and reported OpenRouter had raised a $113 million Series B in May 2026 at a reported $1.3 billion valuation, with Sequoia, a16z, Menlo Ventures, and CapitalG among the investors.
Risk notes
Rumor risk: unofficial dates, valuations, or funding details circulating on social media or forums are frequently wrong or outdated and should not be treated as confirmation of anything.
Illiquidity risk: any private-market interest, indicative marks, or pre-IPO share arrangements in a company that has not listed can be difficult to exit and may not reflect a tradable price.
Timing risk: a company can pause, restart, or abandon IPO preparation at any stage, including after a confidential or public filing, so no step before pricing guarantees a listing.
Can investors request private-company shares on Segmara?
Yes. Start from $25 ($1.00 starter credit available) in USD portfolio credits via Stripe with no password required, or select a listing across 140+ private companies on Segmara to submit a pre-IPO share allocation request.
Why was this market historically hard for individual investors to reach?
Private-company share access has often moved through private equity firms, venture funds, insiders, institutions, and relationship-driven secondary networks. Segmara makes the starting point simpler: browse 140+ named private-company listings, fund USD credits via Stripe from $25 ($1.00 starter credit), and request share allocations with no password wall.
What is the easiest next step?
Start from $25 ($1.00 starter credit available) via instant Stripe checkout (Card, Apple Pay, Link, no password required), or browse Segmara's live pre-IPO listings to select your target company.
Has OpenRouter confirmed an IPO date?
No. OpenRouter has not filed a Form S-1 or F-1 with the SEC on EDGAR as of September 26, 2026. Reporting since July 2026 has focused on a Stripe acquisition, not an independent listing, and no filing or company statement sets an IPO date.
What is OpenRouter's most recent reported valuation?
OpenRouter raised a $113 million Series B in May 2026 at a reported $1.3 billion valuation, per TechCrunch (August 16, 2026), with Sequoia, a16z, Menlo Ventures, and CapitalG among the investors. Axios reported on July 24, 2026 that Stripe's acquisition talks valued OpenRouter at around $10 billion, before Bloomberg's reported agreement priced it above $7 billion.
Is Stripe's acquisition of OpenRouter final?
Bloomberg reported on August 16, 2026 that Stripe had finalized an agreement to acquire OpenRouter for more than $7 billion, a figure TechCrunch confirmed the same day. That is reporting on an agreement, not a company announcement of a closed transaction.
Can I buy OpenRouter shares before the IPO?
Not through a public exchange. OpenRouter is a private company, and current reporting points to an acquisition by Stripe rather than a stock listing. Segmara does not sell, broker, or arrange purchases of OpenRouter shares.
