a16z Blog says Olivia Moore and Justine Moore named the B2A economy as the next distribution shift, with no prediction venue pricing odds or volume and Shopify (NYSE:SHOP) reporting AI traffic up eightfold year over year in Q1 26 as the early signal while most enterprises still block agents over fraud fears.
Shoppers drown in tabs and checkout forms while a helper that knows size and budget could finish the purchase in seconds.
B2A is business to agent commerce where software buys on behalf of a person after it learns intent and constraints.
Today most buying agents work by taking over a browser or spinning up a virtual machine and clicking like a human, per the authors.
Connectors and plug ins let OpenAI ChatGPT call tools like Krea and Descript directly, and in one demo it upsold a paid Descript plan to finish a video ad.
Businesses in ChatGPT lets companies claim a profile and feed product data, and sign in lending would let a user hand identity tokens to an agent so it can pay without retyping cards.
Human Security saw agentic browser traffic grow eightfold between August and October with Claude driving 60 percent and OpenAI products reaching a combined 30 percent, while an estimated 11 percent of shopper journeys visited AI before a transactional site.
Coding agents show the pattern first with upwards of 40 percent of GitHub PRs starting from an agent draft as of September 2026 versus 17 percent six months prior, alongside Supabase reporting more than 60 percent of new databases launched by AI tools and Vercel reporting agent triggered deployments up 28 times in twelve months.
Generative engine optimization is the practice of shaping brand citations inside answers from ChatGPT and Claude, and LLM Pulse tracks 11 platforms that monitor citation and share of voice across ChatGPT and Perplexity and Gemini while agents still fail when docs and error messages do not tell them the next valid call.
Watch for Cognition style tooling and Stripe style docs to decide winners, because agents reread the error and rebuy from scratch every run with no loyalty to save a clumsy checkout.
Not financial advice.
Markets move fast.
