Anthony Pompliano, chief executive and chairman of Silvia, Inc., alleges that Anthropic staff courted his engineers from April to learn how Silvia’s AI finance product was built, then gave the company “a heads-up” days before Claude’s Personal Finance launched on 5 November. Anthropic had not publicly responded as of 00:34 UTC on 6 November.
Silvia’s own SEC filings had named this kind of risk long before the launch. Its Form 10-K, filed on 18 February, already warned that model providers could “prioritize their own competing AI offerings”: 260 days before Claude’s launch, by our arithmetic.
Business Pill · The Model and the Harness
A short Business Engineer explainer on the difference between an AI model and the harness around it. It teaches the general idea only and says nothing about Anthropic, Silvia or these allegations.
The key insight: Pompliano alleges Anthropic courted Silvia’s engineers before launching a rival finance tool, and Anthropic had not publicly responded as of 00:34 UTC on 6 November; Silvia’s own filings had named the risk of model providers favouring their own products since 18 February, 260 days before Claude’s launch, by our arithmetic.
Pompliano made the claims in a post on X at 19:03 UTC on 5 November, quoting Claude’s launch post. It had 644,001 views when we checked at 00:31 UTC on 6 November.
He wrote that “In April, the Anthropic team began heavily courting our engineering team to tell them corporate secrets, technical details, and future plans” for Silvia. He described a steak dinner where, he says, someone told his team “don’t worry about it, this is on Dario.”
Pompliano says his team “refused to share sensitive information and technical details with the Anthropic team.” He says Anthropic staff later “messaged us a few days ago” to give Silvia “a heads-up” that they were launching “a competing product.” He called the launch “a Claude wrapper that is masquerading as a personal finance product.”
These are Pompliano’s allegations. His post names no Anthropic employee other than the reference to Dario, and gives no documents. Decrypt reported the allegations late on 5 November.
Let me tell you a story about how unethical Anthropic is.
In April, the Anthropic team began heavily courting our engineering team to tell them corporate secrets, technical details, and future plans for @cfosilvia.
They pretended their interest was due to our exploding popularity and accelerating compute usage, but it quickly became apparent that Anthropic was fishing for details on how we built our product and why it was so popular.
This included the Anthropic team trying to wine-and-dine our engineers, including a infamous steak dinner where someone told our team “don’t worry about it, this is on Dario.”
Our team was not born yesterday, so we quickly realized what was happening and refused to share sensitive information and technical details with the Anthropic team.
As we suspected, Anthropic was trying to get information from us, so they could build a competing product. Some people on their team must have a guilty conscious because they messaged us a few days ago to give us “a heads-up” that they were launching a competing product.
Thankfully, the Silvia engineering team has been aggressively working to get off the frontier models for the last ~ 6 months. That effort has been highly successful, because our compute costs are ~ 97% lower when we use our own model & hardware, the latency is lower, and the accuracy of answers materially increases as well.
The sad thing for Anthropic is they have now released an inferior product and they had to sell their soul to do it.
The only thing worse than being a trillion-dollar company that can’t beat a 10-person team is being a trillion-dollar company that no one trusts and everyone knows is unethical.
Serious investors continue to choose @cfosilvia over ChatGPT, Claude, and other frontier companies because these products are not optimized to solve the actual user problem.
Today, Anthropic launched a Claude wrapper that is masquerading as a personal finance product. Best of luck to them.
But I will take the Silvia misfits vs the Anthropic losers any day of the week.

Anthony Pompliano, chief executive of Silvia, Inc., posted these allegations on X at 19:03 UTC on 5 November, quoting Claude’s launch post. The post had 644,001 views when we checked at 00:31 UTC on 6 November. The claims are his; Anthropic had not publicly responded as of 00:34 UTC.
Who Silvia Is
Silvia, Inc. is listed on Nasdaq. Its 8-K of 22 September says ProCap Financial, Inc. changed its name to Silvia, Inc. that day, and its shares moved from the BRR ticker to SVIA. Its prospectus of 15 October says Pompliano “serves as our Chief Executive Officer and Chairman.”
The same prospectus says the company acquired CFO Silvia, “an AI agent lab focused on finance”, on 6 April 2026, for total consideration of $23.3 million. It says the CFO Silvia platform “connects to financial account integrations, including brokerage accounts, retirement accounts, cryptocurrency wallets, real estate valuation services, and alternative investment platforms.” Silvia’s website says it is “Trusted by 20,000+ investors” with “$60B+ assets tracked”; those are the company’s own figures.
The Risk Its Filings Named
Silvia’s 15 October prospectus says: “We also rely on third-party providers of foundation models and large language models to power certain features of our AI products, and we have limited control over the development, pricing, availability, or performance of those models.”
It lists what could go wrong, including any “decision by those providers to prioritize their own competing AI offerings”, which it says “could impair our ability to develop and operate our AI products or increase our costs.” An EDGAR full-text search finds the same phrase in Silvia’s 10-K of 18 February 2026, its 424B3 of 4 March, a post-effective amendment of 9 October and the 15 October prospectus.
Silvia’s Answer: Its Own Model
Pompliano says the Silvia engineering team “has been aggressively working to get off the frontier models for the last ~ 6 months.” He says “our compute costs are ~ 97% lower when we use our own model & hardware”, and that latency is lower and accuracy higher. Those are his figures; Silvia’s filings we read do not report them.
The CFO Silvia acquisition closed 213 days before Claude’s launch, by our arithmetic. Anthropic’s announcement says Personal Finance is rolling out in beta on the Pro, Max and Ultra plans in the US, with accounts linked through Plaid and read-only access.
As we read Silvia’s filings, the company built on third-party foundation models and disclosed, months before the launch, that those providers could compete with it.
As we read Pompliano’s post, Silvia’s stated answer is to rely less on frontier models; the cost and accuracy figures he gives are his own and are not in the filings we read.
Silvia, Inc. prospectus, 15 October 2026
“We also rely on third-party providers of foundation models and large language models to power certain features of our AI products, and we have limited control over the development, pricing, availability, or performance of those models.”
Three Implications
FOR SILVIA Pompliano says the company has spent about six months moving off frontier models and says its compute costs are about 97% lower on its own model and hardware.
FOR ANTHROPIC Pompliano’s post had 644,001 views when we checked at 00:31 UTC; Anthropic had not publicly responded as of 00:34 UTC.
FOR APPS BUILT ON MODELS Silvia’s filings list a provider’s decision to prioritize its own competing AI offerings among the risks to its products.
The framework says: “There is no scenario in which product capability outruns model capability over the long term, because every product is built on top of the model.”
As we read it, Silvia’s filings describe the same dependence, and Pompliano says the company’s response is to build on its own model.
What Is Not Established
Anthropic had not publicly responded to the allegations as of 00:34 UTC on 6 November. Pompliano’s post does not say who at Anthropic made the approaches, what was discussed, or whether any information was shared. Nothing we read shows whether Claude’s feature drew on anything from Silvia. Silvia’s 97% cost figure and its own model are not described in the filings we read, and it is not established whether Silvia still uses Anthropic’s models for any feature.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Pompliano alleges that Anthropic courted Silvia’s engineers before launching a rival finance tool, and Anthropic has not publicly answered. Silvia’s own filings show the company had disclosed, since February, the risk that a model provider might favour its own competing product: 260 days before Claude’s launch, by our arithmetic.
A note on sourcing. The allegations are Anthony Pompliano’s, from his post on X of 5 November 2026; we have not verified them, and Anthropic had not publicly responded when we published. Silvia’s role, acquisition and risk-factor details are from its SEC filings; its user and asset figures are its own website’s claims. The view count is our reading at 00:31 UTC on 6 November; the 260-day and 213-day gaps are our arithmetic.
