JPMorgan (JPM) is hosting a major investor event on Thursday evening to get SpaceX's (SPAX.PVT) IPO in front of its base of high-net-worth clients and everyday investors.

Longtime CEO Jamie Dimon will speak at the event from JPMorgan's Manhattan headquarters. The event will be broadcast across 90 private bank offices and select brick-and-mortar branches, according to people briefed on the matter. Dimon has been adamant that JPMorgan leverage its 5,000-location branch network to drum up more investor interest in the IPO, according to a person briefed.

Dimon's key lieutenants, Mary Erdoes and Marianne Lake, heads of JPMorgan's asset and wealth division and sprawling consumer bank, respectively, are expected to speak. SpaceX COO Gwynne Shotwell and CFO Bret Johnson will also be present.

Bank of America (BAC) will also host a fireside chat with Shotwell and Johnson this week. The event is aimed at organizing BofA's massive financial adviser network and high-net-worth clients of its private bank. It will be live-streamed across several of the bank's key markets and Merrill offices.

Both efforts underscore how the nation's largest banks are readying investors for what's set to be the biggest public listing ever.

SpaceX confirmed in a regulatory filing on Wednesday that it's seeking to raise at least $75 billion in proceeds. The rocket maker is looking to raise far more capital from retail investors than the historical standard, according to a person briefed on the matter. It's potentially allocating 30% of shares to retail investors, compared to 10% for most IPOs.

At SpaceX's request, certain shares will be made available through retail investing platforms, including Charles Schwab, Fidelity, Robinhood, SoFi, and Morgan Stanley's E*TRADE.

The company has lined up JPMorgan, Bank of America, and 21 other banks for the IPO, with Goldman Sachs (GS) and Morgan Stanley (MS) taking lead positions. Typical IPO underwriting fees range from 4%-7% of the capital raised. Given the size of the listing, SpaceX is currently negotiating an unusually slim fee of potentially less than 0.75%, according to a person familiar with the deal.

The public debut of Elon Musk's rocket and AI company is expected to make history.

But the massive amount raised is still expected to translate to a significant windfall for bankers. Bloomberg earlier reported on the bank fees and roadshow events.

The major pitch isn't just about this deal's fees either. JPMorgan and other banks are looking to land key roles in the IPOs of AI model makers Anthropic (ANTH.PVT) and OpenAI (OPAI.PVT), expected later this year.

Dimon and SpaceX CEO Elon Musk haven't always seen eye to eye. The two men feuded for several years, beginning in 2016, after JPMorgan refused to underwrite leases for Tesla (TSLA) under Musk's leadership.

But in more recent years, the dynamic has changed. Dimon told CNBC during a January 2025 interview at the World Economic Forum that he and Musk have "settled some of our differences." The Wall Street bank boss applauded Musk, who was then starting the Trump administration's Department of Government Efficiency (DOGE).

It's also far from the first time Dimon has jumped into a major deal to help smooth it over and get it across the finish line. Before negotiating the bank's acquisition of troubled lenders Washington Mutual and Bear Stearns during the financial crisis, Dimon spent much of his early career helping finance mogul Sandy Weill build a financial empire through a merger binge that eventually became Citigroup (C).
