Robinhood
Date: September 29, 2026
Who it affects: Robinhood customers and anyone running AI agents
Official site: robinhood.com
At its HOOD Summit, Robinhood announced Robinhood Agents that trade stocks, options and crypto from a dedicated account using OpenAI or Anthropic models, plus Loops for standing instructions and Agent Apps, paid add ons priced from $5 to $30 a month. It said more than 150,000 agentic accounts had opened since Agentic Trading launched in May. What to do: keep agents in a separate, small account and set your own loss limits.

Public.com
Date: September 24, 2026
Who it affects: Public members with access to Agents
Official site: public.com
Public added AI agents for prediction markets, with contracts supplied by Kalshi. Its general Agents feature launched March 31, 2026 for select members. What to do: prediction markets carry a different risk than stocks, so read the contract terms before an agent touches them.

TradingView
Date: September 16, 2026
Who it affects: Essential plan users and above
Official site: tradingview.com
TradingView opened a public beta of its MCP server so AI agents like Claude can read charts and data. It requires the Essential plan or higher, allows about 100 calls a minute, and serves delayed data. What to do: fine for research agents; do not build fast execution on delayed data.

Interactive Brokers
Date: July 28, 2026
Who it affects: IBKR clients using Claude Code, Cursor, Perplexity and other MCP tools
Official site: interactivebrokers.com
IBKR opened its MCP connector to any MCP compatible tool, and every order still requires the client’s approval. What to do: this is one of the safer agent designs from a major broker, because a human stays in the loop. Keep it that way.

Webull
Date: July 21, 2026
Who it affects: Developers using Webull OpenAPI
Official site: webull.com
Webull added OpenAPI simulation to paper trading across multiple asset classes, so API bots can practice without real money. What to do: if you build on Webull, run every code change through the simulator first.

Alpaca
Date: July 16, 2026
Who it affects: Developers and AI tool builders
Official site: alpaca.markets
Alpaca raised $135 million to build what it calls agent first brokerage infrastructure. It already offers an official MCP server that defaults to paper trading. What to do: expect new AI trading tools to launch on Alpaca early, and check that any new tool uses paper keys by default.

Composer by SoFi
Date: June 23, 2026
Who it affects: Composer users
Official site: composer.trade
SoFi’s deal for Composer, announced June 23, put the product under the Composer by SoFi name. The old Trading Pass is gone; plans now run from a free Starter tier to Pro at $40 a month. What to do: recheck your plan and fees after each product change.

FINRA
Date: Effective June 4, 2026
Who it affects: Anyone who day trades a margin account, bots included
Official site: finra.org
FINRA Regulatory Notice 26-10 replaced the old pattern day trader rule, including the $25,000 minimum and the day trade count, with intraday margin standards. The SEC approved it on April 14, 2026. Brokers have until October 20, 2027 to put it in place, so yours may still apply the old limits. What to do: ask your broker which rule your account runs under before a bot starts day trading.

What we report
- New AI trading bots. Launches worth a look, and the ones worth a skip.
- Pricing and plan changes. When a free tier shrinks or a feature moves behind a paywall.
- Broker API updates. New authentication, rate limits, or endpoints that can break a live bot.
- Outages. When a platform or broker connection goes down during market hours.
- AI features from brokers. New assistants, screeners, and automation tools built into trading apps.
- Regulation. SEC, FINRA, and CFTC moves that affect automated retail trading and AI marketing claims.
How every story is written
Each news post answers three questions in the first few lines:
- What happened, with the source.
- Who it affects, by broker, bot, or account type.
- What to do now, if anything.
NO BS, no price predictions, no “this changes everything.” If a story does not change what you should do, we say so.
Why a news section on a bot review site
Because the fastest way to lose money with a trading bot is to find out about a change after it breaks your strategy. A broker updates its API on a Friday, and a bot that ran fine all week sends bad orders on Monday.
News also keeps our reviews honest. When a pricing change or outage hits a bot we have scored, the AI Trading Bot Reviews page gets updated and the change is dated.

Our take
We started this news desk because the AI trading tool market changes faster than any static review can keep up with. Pricing pages change without notice. Free tiers shrink. Broker APIs switch login methods on a Friday. If you run a bot, those changes are not trivia, they are risk. Every story here ends with what it means for your account, because news you cannot act on is just noise. If you spot a change we missed, send it in. Reader tips are some of the best early warnings we get.
Quick answers
Can I use AI for trading?
Yes. Traders use AI to scan for setups, summarize news, write strategy code, and run automated rules through a broker. AI does not remove risk. The useful question is which part of your process it improves, and how you check its work.
Is AI trading really working?
AI trading tools work as tools. They can speed up research and execution, and some traders use them well. Claims that AI produces steady profits on its own are not supported by evidence. Follow our news coverage for what changes, and our reviews for what holds up.
What AI trading news matters most if you run a bot?
Broker API changes, outages during market hours, and pricing or plan changes matter most, because each one can break a live strategy or raise its cost overnight. New bot launches matter next. Hype about AI stocks matters least for bot users.
