JPMorgan ended a formal Polymarket banking relationship. The rest of the tie is company-described.

JPMorgan Chase ended a formal banking relationship with Polymarket in October 2025 and told the company to find another bank, the Financial Times reported on 14 August 2026 — according to independent write-ups opened for this page, not the FT article itself, which timed out behind a paywall.

crypto.news printed that lede and said the reason given was regulatory concerns. CoinDesk and CryptoBriefing reported the same FT peg. PYMNTS dated the FT story to Friday 14 August and said it cited unnamed sources. A Reuters wire the same day, bylined Nupur Anand and Manya Saini, reported the October termination citing a person familiar with the matter and noted the FT had the story first.

That is the public record on the account. It is not, on these pages, a record that every JPMorgan tie is gone.

What the opened pages say happened next

The same reports say Polymarket has since moved to another lender. Every opened page leaves that bank unnamed.

crypto.news printed Polymarket’s words to the FT: the company maintains “a close, active relationship with JPMorgan across multiple entities, operational integrations and material handling of customer fund flows.” PYMNTS printed a shorter cut of the same line, plus “Any suggestion otherwise fundamentally mischaracterizes our relationship.” Reuters printed an emailed spokesperson statement with both of those sentences and a further claim: “The strength of our relationship is highlighted by our CEO speaking at three of their flagship events in the past year alone.”

crypto.news added a limit that this page keeps: the company’s description of the remaining relationship has not been independently detailed publicly.

What JPMorgan said — and did not

On the opened pages that asked, JPMorgan declined to comment (crypto.news; PYMNTS, which said it reached the bank). No opened page prints a JPMorgan description of the remaining operational integrations or of how customer fund flows are still handled. That description is UNKNOWN here.

Conference talk and IPO talk are not a filing

crypto.news and CoinDesk, attributing the FT, said JPMorgan invited Polymarket CEO Shayne Coplan to a private client conference in February 2026 (crypto.news locates it in Miami). Those same write-ups said the bank is reportedly interested in an underwriting role if Polymarket eventually pursues an IPO. CryptoBriefing reported the same IPO-role framing. No opened page identified a public registration statement. Reported interest is not a listing.

The Reuters company quote (“three of their flagship events in the past year”) is a broader count than the single February conference named in the FT-via-secondaries copy. This page reports both. It does not invent a list of three events.

The $1 billion / $20 billion figures are reported targets

Separately, crypto.news said Reuters reported on 4 August, citing Bloomberg, that Polymarket was in early talks to raise roughly $1 billion at a valuation above $20 billion. crypto.news said Reuters could not independently verify that report and that Polymarket did not respond. PYMNTS also printed a 4 August line of “about $1 billion” at “a valuation north of $20 billion.” Those figures stay marked as reported targets. They are not treated here as a completed financing.

What this page does not claim

• That JPMorgan has ended every commercial relationship with Polymarket.
• That the remaining “operational integrations” and “customer fund flows” have been independently mapped.
• The name of the successor bank.
• That an IPO will happen, or that the $1 billion talks have closed.
• A live price, a position, or trading advice.
