Interactive Brokers reported a record $182 billion in idle client cash in its Q2 2026 results. The company earns interest on these funds, which could be impacted if clients divert their capital to invest in the upcoming public offering of AI company Anthropic.

Anthropic, the developer of Claude AI, confidentially filed its draft S-1 registration statement in June 2026. The company expects to launch its IPO in mid-October 2026.

Financial observers and analysts are monitoring the timing and pricing of the IPO as key indicators of how much cash will be shifted from Interactive Brokers' client accounts to the new AI venture.
