IPO Ballot Singapore

IPO ballot Singapore refers to the random allocation process for retail investors when a Singapore Exchange (SGX) IPO is oversubscribed — meaning more share applications are received than shares available in the public offer tranche. The ballot is conducted by the share registrar appointed by the issuer. This page is for general information only and does not constitute financial advice.

Why Is a Ballot Needed?

Popular IPOs in Singapore — especially S-REIT listings — can be oversubscribed by 10× to 100× or more. When demand far exceeds supply, a random ballot fairly allocates the available public offer shares. The process is transparent and computerised, managed by MAS-regulated share registrars such as Boardroom, Tricor, or Computershare.

How the SGX IPO Ballot Works

  1. Applications close at the stated deadline (usually 12pm on the closing day)
  2. The share registrar compiles all valid applications, grouped by number of lots applied for
  3. A ballot ratio is determined — for example, “1 in 10 applicants of 1 lot receive 1 lot”
  4. A computerised random draw selects successful applicants
  5. Results are announced typically 2–4 days after closing
  6. Successful applicants’ CDP accounts are credited; unsuccessful applicants receive full refunds

Ballot Outcomes by Oversubscription Level

Oversubscription Typical Outcome for Retail
2× – 5× Most applicants receive some shares; larger applications may be fully met
10× – 30× Fraction of applicants succeed; minimum lots likely
50× – 100×+ Very few applicants succeed; even large applications may get 1 lot or nothing

Tips for Singapore IPO Applicants

  • Apply for the maximum lots you can afford: Larger applications can marginally improve odds without proportional benefit in heavily oversubscribed IPOs
  • Multiple CDP accounts in the household: Each eligible family member (spouse, adult children) can apply separately using their own CDP account — one application per CDP per IPO
  • Do not tie up money you need: Funds are blocked during the offer period; refunds come after the listing date
  • Read the prospectus first: Understand business risks, use of proceeds, and financial health — ballot success is not guaranteed profit

After the IPO Ballot

Successful applicants receive shares in their CDP account on the listing date. The stock begins trading and prices may move sharply above or below the IPO price.

Frequently Asked Questions

How do I check IPO ballot results in Singapore?
Ballot results are announced in the press (Business Times, Straits Times) and via SMS if you registered your mobile. You can also check your CDP account — allotted shares appear by the listing date. Unsuccessful applicants see a refund in their bank account within 1–3 business days of the listing date.
Does applying for more lots improve my IPO ballot chances?
Somewhat. SGX IPO ballots group applications by lot size. Applying for more lots may marginally improve your odds, but the benefit is not linear. In 50×+ oversubscribed IPOs, even large applications may receive only 1 lot. Spreading applications across eligible family members’ CDP accounts is the most effective way to increase household allocation chances.
What happens to my money if I am unsuccessful in an IPO ballot?
Your application funds are held by the share registrar during the offer period. If unsuccessful, the full amount is refunded to your bank account (or CPF/SRS if applicable) within 3–5 business days of the listing date. No interest is earned on funds held during this period.
Can I apply for the same IPO through multiple brokers?
No. Each CDP account holder may only submit one application per IPO regardless of how many brokers they use. Multiple applications using the same CDP number violate IPO terms and may result in all applications being rejected. Different family members with separate CDPs may each submit their own application.
Can I use CPF to apply for an IPO in Singapore?
Some IPOs allow CPF OA funds under CPFIS. This is stated in the prospectus. REIT IPOs are more likely to be CPF-eligible than equity IPOs. Check the prospectus “Use of CPF Funds” section before applying. Note that CPF withdrawals for investment are only allowed for amounts above S$20,000 in the OA.
