Fireblocks has rejected an Axios report that Visa was in advanced talks to acquire the digital-asset infrastructure company for about $2.5 billion. Fireblocks said the reported discussions were not taking place at present. Visa declined to comment on the claim, while Coinbase separately denied reports that it was considering a bid. None of the companies has confirmed an acquisition process. The reported price would be about 69% below Fireblocks’ $8 billion valuation from its January 2022 Series E funding round. The company generated $124 million in revenue in 2024 but remained unprofitable, and it has initiated plans to cut 60 to 70 jobs amid the rumors. Visa already uses Fireblocks as an institutional client and works with it on an interoperability initiative. Those existing links provide context for the speculation, but do not establish that a transaction is under discussion.

Coinbase demonstrated machine-to-machine AI payment workflows at Sibos 2026 in Miami Beach, highlighting the Model Context Protocol, Agent-to-Agent protocol and its x402 payment standard. The demonstration followed the August general availability of Amazon Bedrock AgentCore Payments, which incorporates Coinbase Developer Platform wallet infrastructure and x402 settlement. The AWS service supports Coinbase Developer Platform and Stripe Privy wallets for autonomous USDC microtransactions, while keeping developer credentials separate from AI agents and applying deterministic spending limits. The work connects a conference demonstration to infrastructure already available to developers. Coinbase and AWS had also enabled publishers and API endpoints using AWS CloudFront and AWS WAF to monetize autonomous agent traffic through x402. Coinbase Institute research argues that AI agents need sub-cent stablecoin payments, although that argument is not evidence of transaction volumes. The developments show how payment authorization, wallet access and settlement are being assembled for agent-initiated transactions, without establishing how widely the technology is used.
