Why Did Marvell (MRVL) Stock Rise on Oct 6, 2026? The Investor Day Targets

Marvell Technology (NASDAQ: MRVL) rose 5.81% to close at $287.01 on Tuesday, October 6, 2026, after telling its investor day in New York that it expects about $20 billion of revenue in fiscal 2028 and sees a market of about $400 billion for its products by 2030. The market-size headline reached the MoveSurge news feed at 09:25:17 ET, before the open, with the stock at $269.64. It was at $270.13 a minute later, at $287.36 after ten minutes, up 6.57%, and at $294.12 after fifteen, up 9.08%, before giving back part of the gain during the regular session.

Marvell investor day targets, October 6, 2026

Marvell's fiscal 2028 ends on January 29, 2028, so the $20 billion target roughly covers calendar 2027 and is the nearest of the new numbers. It implies growth of about 67% over fiscal 2027. The company had already raised the same target once this quarter, when it reported second-quarter results on August 27, and the October figure sits $3.5 billion above where it stood before that report. Chief executive Matt Murphy said data center revenue of about $18 billion in fiscal 2028 would reach the company's fiscal 2029 data center goal almost a year early.

Where Marvell expects the $400 billion market to come from

Custom silicon, meaning the accelerators Marvell designs for cloud companies together with the chips attached to them, accounts for about $235 billion of the 2030 market estimate. Switching and storage account for about $85 billion, interconnect, the electro-optical parts that carry data between AI servers, for about $65 billion and communications for about $15 billion.

The fiscal 2031 revenue plan is weighted the other way. At the $80 billion midpoint of the $70 billion to $90 billion range, Marvell's breakdown puts interconnect at about $37.5 billion and custom silicon at about $30 billion, followed by switching and storage at about $10 billion and communications at about $2.5 billion. Fiscal 2031 ends in early 2031, so it lines up with the calendar-2030 market estimate. Read together, the plan has Marvell taking more than half of the interconnect market it sized and roughly an eighth of the custom silicon market, so the larger share of the forecast revenue comes from optics even though custom silicon is by far the larger market.

How Marvell's last three catalysts traded, measured

The August and October events both raised the fiscal 2028 outlook and drew opposite reactions. In August the raise arrived inside the quarterly report, which showed revenue of $2.739 billion, up 37% from a year earlier, data center revenue of $2.171 billion, up 46%, and third-quarter guidance of $3.150 billion, plus or minus 5%. In October it arrived with the long-range market sizing and the first revenue range for fiscal 2031. In each of the three cases the first fifteen minutes pointed the same way as the close.
