OpenFX Raises $94M Series A With Accel and Pantera

OpenFX, the FX startup co-founded by FalconX alum Prabhakar Reddy, closed a $94 million Series A led by Accel with participation from Atomico, Lightspeed Faction, M13, Northzone and Pantera Capital. The round values the company at roughly $500 million and confirms that stablecoin-powered cross-border rails are crossing from speculative narrative into core financial infrastructure.

What happened

OpenFX raised a $94 million Series A to scale an API-first FX network that uses stablecoins as the settlement leg between traditional bank rails. The syndicate is rare in its composition: tier-one generalist VCs (Accel, Atomico, Northzone) sitting alongside a deeply crypto-native fund (Pantera) and a stablecoin-focused vehicle (Lightspeed Faction). That blend is the story.

Founded in 2024 by FalconX co-founder Prabhakar Reddy, OpenFX now claims more than $45 billion in annualized payment volume, up from $4 billion a year ago. That is an order-of-magnitude jump in twelve months, and it explains why investors stretched into a half-billion-dollar valuation for an infrastructure player most consumers will never directly use.

Why stablecoins, why now

Traditional FX corridors clear through correspondent banking, SWIFT messaging and a chain of intermediaries that introduce float, fees and friction. OpenFX uses regulated stablecoins (USDC, USDT and tokenized USD variants) as an intermediate hop, allowing a US importer to pay a Vietnamese supplier in seconds rather than days. The dollar leaves the US bank, becomes a stablecoin on-chain, then is converted to local currency on the receiving side.

For the user, nothing changes. For the rails, almost everything does. Settlement risk collapses, working capital improves, and FX spreads compress because liquidity providers no longer need to pre-fund local accounts in every corridor. That is the thesis Pantera and Faction have been underwriting for three years; OpenFX is one of the first companies to put real volume behind it.

Where the capital is going

The capital will accelerate two priorities. First, Southeast Asia: corridors into Indonesia, the Philippines and Vietnam where remittance volume is large and traditional FX spreads remain wide. Second, deepening Latin American liquidity, building on existing rails into Mexico, Colombia and Brazil where US importers and exporters are already routing payroll and supplier payments through stablecoin intermediation.

The competitive landscape

OpenFX is not alone. Bridge (acquired by Stripe for $1.1 billion in late 2024) is the headline comparable, while Conduit, Felix Pago, Mural, ZeroHash and a long tail of regional players are all chasing the same opportunity. What differentiates OpenFX is the explicit API positioning: the company sells to fintechs, neobanks and payment service providers who do not want to build their own stablecoin treasury stack.

That B2B2C layer is where Pantera has been concentrating bets in 2026. Rather than betting on a winner-takes-all consumer brand, the thesis is that dozens of fintechs will need infrastructure plumbing, and the company that wins the developer relationship at the API layer captures the long-tail volume. OpenFX is one of three Pantera infrastructure bets in this category over the past six months.

Market impact and signal

Three signals to take from this round. First, stablecoin payment volume is no longer a venture story; it is a revenue story. A company doing $45 billion in annualized flow is generating real take-rate revenue, even at thin margins. Second, generalist tier-one funds are now leading these rounds, not following. That is a meaningful shift from 2023, when Accel and Atomico would only follow crypto-native leads. Third, the regulatory tailwinds matter: the GENIUS Act and FinCEN's stablecoin AML framework have given enterprise treasurers explicit cover to use these rails.

For token markets, the read-through is indirect but real. Increased stablecoin payment flow means more USDC and USDT velocity, which historically correlates with broader on-chain activity. Layer-2s that host stablecoin payment volume (Base, Arbitrum, Polygon) benefit on the margin. Tokens directly exposed to the stablecoin theme (Ethena's ENA, Sky's SKY, Resolv) are the most obvious second-order beneficiaries.

Risks worth flagging

A second risk is platform concentration. If OpenFX's volume is heavily concentrated in a small number of large enterprise clients, those relationships become single points of failure. Public payment infrastructure companies (Wise, Remitly) trade at premium multiples partly because their volume is diversified across millions of consumers. OpenFX is closer to the enterprise-API model, which historically supports lower multiples in public markets.

Where to track this story

The next milestones to watch are the Southeast Asia corridor launches (Vietnam and the Philippines are the most likely first markets), partnership announcements with regional banks or fintech aggregators, and any disclosure of corridor-level take rates. A Series B at a meaningfully higher valuation within twelve to eighteen months would confirm the thesis; a quiet round at a flat valuation would signal that growth has slowed.

For traders, monitor stablecoin issuance velocity on-chain (USDC and USDT mints into corridor wallets), Layer-2 stablecoin TVL trends, and watch DEXTools for liquidity moves in stablecoin-adjacent tokens. The crypto market often prices in payment infrastructure narratives weeks before the equity market does.
