X Has the Traders. Now Brokers Are Competing for Their Orders

• X launched its U.S. Cashtag Partner Program with five brokerage and crypto platforms.
• Trades are completed by partners rather than directly on X.
• X said an earlier Cashtag pilot drove an estimated $1 billion in global trading volume in three days.
• The bigger opportunity may be controlling which broker receives users when market interest becomes trading intent.

X has officially connected Cashtags with Interactive Brokers, Moomoo, Coinbase, Kraken and Gemini in the U.S., but the more interesting story is not the new Trade button. It is what happens to an investor after they press it.

The Cashtag Partner Program, launched September 15, allows users to open a supported stock, ETF or cryptocurrency ticker, view its price chart and related posts, and then select a trading provider. Execution remains outside X, on the partner’s app or website.

That distinction changes the economics of the product. X does not need to become a brokerage to participate in the trading funnel. It already occupies something brokers spend heavily to acquire: the investor’s attention immediately before a potential trade.

And X has already claimed that attention can translate into substantial activity.

A $1 Billion Pilot Changes the Cashtag Story

When X introduced its redesigned Cashtag experience earlier this year, the feature initially centered on asset discovery, price information and financial conversation.

Three days after the April launch, X Head of Product Nikita Bier said aggregated data from its trading pilot indicated the platform had driven an estimated $1 billion in global trading volume. The figure was reported by X and has not been independently audited, so it should be treated as a company estimate rather than verified transaction data.

Still, it provides useful context for the new partner program.

The question in April was whether users who encountered assets on X would actually move from discussion toward execution. The September rollout asks a different question: which financial platform captures those users once they decide to act?

That is where the five launch partners become more significant.

Coinbase, Kraken and Gemini are competing for crypto users, while Interactive Brokers and Moomoo provide routes into conventional markets. X sits above them as the discovery interface rather than underneath them as the execution infrastructure.

The Trade Button Is Also an Acquisition Button

Interactive Brokers provides the clearest evidence of how financial companies may value that position.

Eligible new U.S. clients who open and fund a qualifying IBKR account through the Cashtag experience receive $100 to start investing, according to the broker’s official announcement. Existing customers can move from a ticker on X into Interactive Brokers to conduct further research or place a trade.

That turns a Cashtag into something more measurable than a financial-content feature.

For a broker, there is a substantial difference between advertising to someone scrolling through a social feed and receiving a user who has already opened $BTC or $AAPL, checked the market and deliberately pressed Trade.

The second user has demonstrated intent.

X Product Engineering Lead Mridul Singhai described Cashtags as closing the gap between seeing a ticker on the timeline and reaching the market. The commercial value of closing that gap is that fewer stages of the customer journey occur before the brokerage handoff.

How the new funnel works

• Financial post → $Cashtag → Price and discussion → Trade → Broker selection → Execution

X controls the first four stages. Its partners take over when an account, regulated execution or custody is required.

That division could prove considerably easier to scale than X building those functions itself.

Twitter Tested the Idea With eToro Years Ago

There is also an important precedent that makes the current rollout less experimental than it initially appears.

Twitter partnered with eToro in 2023 to expand real-time pricing through Cashtags and allow users to click through to the investment platform. Reuters reported at the time that the integration covered stocks, cryptocurrencies and other assets.

The difference is structural.

The earlier arrangement directed users toward eToro. The new Cashtag Partner Program introduces multiple competing destinations across traditional brokerage and crypto.

Historical data also shows why that placement could be valuable. X reported that more than 1.4 billion posts referenced trading or investing in 2023, up 54% from the previous year, including more than 324 million posts from U.S. users. Those figures are historical and should not be treated as a measure of X’s current financial audience, but they illustrate the scale of the behavior Cashtags were built around.

The platform is therefore not creating financial intent from scratch. It is trying to build infrastructure around activity that already happens there.

Crypto Exchanges Now Compete Before Users Open an Exchange

That creates a particularly interesting change for Coinbase, Kraken and Gemini.

Crypto exchanges traditionally compete after investors have decided they want to trade digital assets. Marketing, search, app distribution and brand recognition help determine which platform the customer opens.

Cashtags potentially move that competition one stage earlier.

Someone following a Fed announcement, earnings report or breaking crypto story may move between $BTC, $ETH, $COIN and $SPY without thinking in terms of separate crypto and equity ecosystems. The Trade button can present financial providers while that decision is still being formed.

For Kraken, the integration extends to more than 2,400 crypto assets, according to reporting on the launch.

That makes X less like another exchange interface and more like a distribution layer sitting above several financial platforms.

The Numbers X Needs to Prove the Model

The next useful Cashtag statistics are not impressions, searches or posts.

They are Trade-button conversion, funded accounts, trading volume by partner and customer-acquisition economics.

Interactive Brokers’ $100 incentive already shows that at least one partner is willing to attach a concrete acquisition cost to customers arriving through X. The reported $1 billion pilot, meanwhile, suggests X believes it can generate meaningful downstream trading activity.

Neither figure proves the model yet. The pilot number comes from X itself, while a promotional bonus tells us what a broker is willing to offer, not whether those customers ultimately become profitable.
But together they establish a much more interesting benchmark for the Cashtag program than the existence of a Trade button.

If X can repeatedly deliver funded customers and trading volume, brokers may eventually have to think about Cashtag distribution in the same way they think about search, app stores and other acquisition channels.

The important competition may not be over who executes the trade. It may be over which broker X sends the trader to first.
