Bullpen vs Senpi: a terminal for perps, Polymarket and Solana tokens, or an AI agent that runs your Hyperliquid perps
Bullpen and Senpi both trade Hyperliquid perps, and that is where the overlap ends. Bullpen is an all-in-one terminal: Hyperliquid perps and spot, Solana tokens through Jupiter Ultra, and Polymarket prediction markets from one self-custodial wallet, with smart-money tracking and one-click copy trading on Polymarket wallets, a CLI that Claude Code can drive, and same-day ACH in and out. Senpi is an AI trading agent for Hyperliquid: you describe a strategy in a sentence and the agent writes it, runs it 24/7 under a risk harness, protects every strategy built from a rule or a template with DSL, and reads wallets with a proven record for you, from the app, from Claude or ChatGPT, or from the Chrome Companion.
The honest split: Senpi wins where you want a perp strategy built, run and protected for you; Bullpen wins where you want predictions, Solana tokens and perps in one place and a feed of what Polymarket whales are doing. Facts below come from bullpen.fi and docs.bullpen.fi (trading, smart money, funding, FAQs), DefiLlama’s on-chain record of its Hyperliquid builder fees, senpi.ai/pricing and senpi.ai/fees, as of Nov 7, 2026.

What Bullpen is built for
Polymarket smart money and copy trading
Discover, Trending, Walletscope and Eventscope views of profitable Polymarket wallets, convergence signals, alerts, and one-click automatic copying.
Three venues from one balance
Hyperliquid perps and spot, Solana tokens with MEV protection, and Polymarket, with cross-chain transfers inside the app.
A bank account on both ends
Card, Apple Pay, Google Pay, ACH or wire in through fun.xyz, and same-day ACH withdrawals out, with $BULL points and competitions on top.
The agent, and where you reach it
Bullpen has a CLI your coding agent can drive. Senpi is the agent.
| Criterion | Bullpen | Senpi |
|---|---|---|
| Inside AI assistants | A CLI with skills for Claude Code and Codex: plain-English requests become Polymarket commands (buy shares, limit orders, alerts, top traders), run on request through your session; no perps, no autonomy | Senpi Connectors for Claude, ChatGPT, Grok, Hermes and Muse: one address and a Senpi sign-in, then your agent answers inside the assistant you already use |
| On the sites you read | app.bullpen.fi only | Senpi Companion, a Chrome extension on 28 sites: X, Hyperliquid, TradingView, Binance, Coinbase, OKX and more |
| What the Companion does | Not applicable | Quant Desk on any wallet you see, the Signals brief for the asset on screen, and Trade the Take: a post or headline becomes a trade setup with size and stop |
| Phone | Home-screen web app on iOS and Android; no native app | iOS and Android apps |
Senpi's edge here
Bullpen’s CLI skills are a real developer feature and the page scores them a tie on the developer row. They are not an agent: they map your request to a Polymarket command and stop. Senpi’s agent writes and runs the perp strategy itself, and reaches you inside the assistants and the sites you already use.
Senpi Signals vs Whales, Insights and Polymarket smart money
Both read other wallets. Bullpen reads them on three venues; Senpi scores them on one.
| Criterion | Bullpen | Senpi |
|---|---|---|
| The read | Whales (large-wallet inflows and buys), Runners for breakout tokens, Hyperliquid Insights for net positioning, open interest and volatility, and Polymarket smart-money views with convergence signals | Senpi Signals: per asset, the biggest recent moves from proven wallets set against the broader cohort, scored, with the driver named |
| One wallet in depth | Walletscope on a Polymarket wallet; leaderboard profiles with current positions | Quant Desk: a score over six explained dimensions, a protection audit of the live book, leaks priced in dollars, on any Hyperliquid address |
| Alerts | Smart-money alerts on specific trades or trader profiles; real-time notifications | An alert when any wallet you add opens, adds or cuts, plus the agent’s own read before it trades |
| Where it reaches you | In the terminal and its notifications | In the app, in Claude or ChatGPT, on the Companion while you read X or TradingView, and inside the agent’s reads |
Senpi's edge here
For Polymarket, Bullpen’s smart-money layer is the deeper one and Senpi does not compete. For Hyperliquid perps, Signals and Quant Desk score the wallets with a record and the market they sit in, and the agent acts on the read.
From an idea to a protected position
Building, running, following and protecting on perps.
| Criterion | Bullpen | Senpi |
|---|---|---|
| Starting point | A market on the ticket, or a Polymarket wallet to copy | A sentence: “short ETH when funding flips positive and open interest is at a 7-day high, max 2% of equity” |
| Building and running | You place every order; a full manual palette including TWAP and scale | The agent researches, writes the strategy, shows you the rules before anything opens, then a hosted runtime runs it 24/7 under a risk harness; edits apply live |
| Following a trader | Copy Polymarket wallets automatically with one click; on Hyperliquid, track whales and place the trade yourself | Mirror a trader you choose, after it researches their record, 0.1x to 4x, with the fee load checked and an exit attached |
| Exits and halts | TP/SL, stop-market and stop-limit per position; no daily-loss or drawdown halt across the account | DSL on every strategy built from a rule or a template; cooldowns, optional daily-loss and drawdown halts per strategy; watch-only alerts on wallets you add |
Senpi's edge here
Bullpen’s copy trading is built for Polymarket and it is a good implementation; on perps you are the operator. Senpi is for the trader who wants the perp strategy built, operated and protected, and the follow researched and sized by rule for a trader you choose. Neither product can promise a fill at a stop’s trigger price.
Venues, predictions and cost
Where Bullpen is built to win, and what each costs.
| Criterion | Bullpen | Senpi |
|---|---|---|
| Venues | Hyperliquid perps and spot, Solana tokens via Jupiter Ultra, Polymarket, one balance | Hyperliquid perps only |
| Prediction markets | Polymarket order book, smart-money discovery, convergence signals, one-click copy | None |
| Funding and cash-out | Card, Apple Pay, Google Pay, ACH, wire, wallet; same-day ACH out to a bank | Card, Apple Pay or Google Pay through the on-ramp, or USDC on seven chains; crypto withdrawals only |
| Cost of $150K a month of perps | About $44 to $68 in builder fee (0.029% on-chain average; 4.5 bps taker at the first tier), plus Hyperliquid’s 0.015% to 0.045% | $50 on Pro, whatever the volume, plus Hyperliquid’s 0.015% to 0.045% |
Winner: Bullpen
If your trading spans predictions, Solana tokens and perps, or you want ACH on both ends, Bullpen wins and Senpi does not compete. On perps the cost lines cross between roughly $110K and $170K of monthly volume depending on your tier: below that Bullpen’s builder fee is cheaper than a Pro plan, above it the subscription is.
Where Senpi is stronger
An agent inside Claude, ChatGPT and your phone
Senpi Connectors for Claude, ChatGPT, Grok, Hermes and Muse, iOS and Android apps, and the Companion on 28 sites.
Signals from proven wallets
Per-asset reads of what wallets with a record are doing against the crowd, alerts on any wallet you add, Quant Desk on any address.
Strategies written, run and protected for you
From a sentence to a 24/7 runtime with DSL on every strategy built from a rule or a template and optional halts per strategy, and mirrors of traders you choose, sized by rule.
Which should you choose?
Choose Bullpen if
- You trade Polymarket and want smart-money feeds and one-click copying there
- You want perps, predictions and Solana tokens from one balance
- You want to move money in and out of a bank by ACH
Choose Senpi if
- You want your trading agent inside Claude, ChatGPT or your phone
- You want a Hyperliquid perp strategy written, run and protected for you
- You want proven-wallet signals and a wallet score on the Hyperliquid wallets you follow
Conclusion
Senpi is the agent. It writes the strategy from a sentence, runs it 24/7, protects every strategy built from a rule or a template with DSL and optional per-strategy halts, reads wallets with a record instead of a feed, and comes to you inside Claude, ChatGPT, Grok, Hermes or Muse, on your phone, or on the Companion while you read X or TradingView. For a trader who wants Hyperliquid perps run with help, that is the whole case.
Senpi Signals and Quant Desk give you a scored read of the Hyperliquid wallets Bullpen only tracks: what proven wallets are doing against the crowd, and a six-dimension score on any address, with the leaks in your own book priced in dollars.
Senpi’s price is flat: $50 a month on Pro with 0% Senpi fee, so a busy month costs the same as a quiet one, and above roughly $110K to $170K of monthly perp volume it is cheaper than Bullpen’s builder fee.
Bullpen is the better terminal for what it was built for: Polymarket smart money with one-click copying, Solana tokens and Hyperliquid perps from one balance, and a bank account on both ends. If that is your trading, Bullpen; if your trading is Hyperliquid perps with an operator behind them, Senpi. One is a terminal across three venues; the other is an operator on one.
Frequently asked questions
Does Bullpen use Hyperliquid?
Yes. Every Hyperliquid perp market is tradable with up to 50x leverage, cross or isolated margin, and market, limit, stop, TP/SL, TWAP and scale orders, and Hyperliquid spot routes through UNIT. Bullpen also trades Solana tokens through Jupiter Ultra and Polymarket through its order book. Senpi trades Hyperliquid perps only, through the agent.
What are Bullpen’s fees?
Published in its FAQ: on Hyperliquid perps a builder fee tiered by 30-day volume, from 4.5 bps taker and 3.5 bps maker down to 0.5 and 0.2 bps, on top of Hyperliquid’s own fees; Hyperliquid spot charges 10 bps on sells and nothing on buys; Solana swaps carry route fees shown before you trade. On-chain, Bullpen’s perps builder code collected about $14.3K on $49.9M of volume in the 30 days to Nov 7, 2026, about 0.029%. Senpi charges 0% on every paid plan (Pro $50, Advanced $100, Quant $200 a month), 0.03% on the free trial or without a paid plan, plus Hyperliquid’s fees.
Does Bullpen have copy trading?
For Polymarket, yes: one click mirrors a profitable Polymarket wallet automatically, with smart-money discovery, convergence signals and alerts around it. For Hyperliquid perps, Bullpen tracks whales and shows leaderboard positions, and you place the trade. Senpi’s mirrors are set up by the agent after it researches a Hyperliquid wallet you choose, sized 0.1x to 4x, which can carry a flat stop.
Can Claude Code trade on Bullpen?
Yes, on Polymarket. Bullpen’s CLI ships agent skills for Claude Code and Codex: you ask in plain English and the assistant runs Bullpen CLI commands through your session to buy shares, place limit orders or set whale alerts, on request. Senpi’s agent is the product itself: it writes and runs Hyperliquid perp strategies, and Senpi Connectors expose it inside Claude, ChatGPT, Grok, Hermes and Muse.
How do you fund Bullpen?
Through fun.xyz: connect a wallet, transfer crypto, pay by card, Apple Pay or Google Pay, or send ACH or a wire for larger amounts; withdrawals to a bank account go by same-day ACH. Perps need USDC, Polymarket needs USDC.e on Polygon, Solana tokens need SOL. Senpi takes a card, Apple Pay or Google Pay through its on-ramp, or USDC on seven chains, and withdraws to crypto.
Is Bullpen non-custodial?
Yes. Wallets run on Turnkey, Bullpen never has access to your funds, and you can export your private key from the Portfolio page. Senpi’s wallets are non-custodial too, with exportable keys; each strategy trades from its own funded strategy wallet, the agent holds no keys, and withdrawals are made by you in the app, behind MFA.
Who should not pick Senpi?
Anyone who trades Polymarket or Solana tokens: Senpi trades Hyperliquid perps only. Anyone who needs ACH withdrawals to a bank. And anyone trading a small book: below roughly $110K to $170K of monthly perp volume, Bullpen’s builder fee costs less than a $50 Pro plan.
Can I run Senpi from Claude or ChatGPT?
Yes. Senpi Connectors put your Senpi agent inside Claude, ChatGPT, Grok, Hermes and Muse: you ask it to research a market, build or edit a strategy, review a wallet or close a position, and it does it on Hyperliquid without you opening the app.
What are Senpi Signals and the Senpi Companion?
Signals are per-asset reads of what proven wallets are doing against the broader cohort, scored and with the driver named. The Companion is a Chrome extension that brings Senpi onto 28 sites, including X, Hyperliquid, TradingView, Binance, Coinbase and OKX: Quant Desk on any wallet you see, the Signals brief for the asset on screen, and Trade the Take, which turns a post into a trade setup.
What is DSL?
Senpi’s dynamic stop. It starts at a loss-protection floor and moves the floor up as a position gains, so a trade exits on structure rather than on hope. No stop can guarantee a fill at its trigger price.
